lt3f DR. PRIESTLEY LAYS A TRAP By JOHN RHODE The death of Lessingham and his companion, Purvis, was, indeed, a tragic affair; but an automobile accident, especially one occurring in a race, rarely arouses suspicion. Sergeant Showerby, however, was a conscientious soul. His duty was to investigate thoroughly and investigate he did, with results that were suspicious enough to arouse Inspector Hanslet of Scotland Yard and, through him, the great criminologist, Dr. Priestley. At first, there is so little evidence that one cannot under- stand Dr. Priestley's interest in the.case. Then, one by one, clues appear—not the ordinary clues which fall fortuitously in a detective's lap, but clues that are found because the Doctor, by his famous process of logical deduction, knows where to look for them. Gradually a pattern forms so dia- bolical in its simplicity and effectiveness that Dr. Priestley is forced to set a dramatic trap which very nearly ends the lives of both detective and criminal. For sheer ingenuity of detective story mechanics, John Rhode has few equals and none of his many stories present a neater puzzle than this one, which will perplex all but the keenest detective fans.

To NUMBER 187 AND HER DRIVERS March lst-3rd, 1932 CHAPTER I The British Motor-Car Rally of that year, organized by the Royal Automobile Club, was generally voted to have been a huge success. But it proved a bitter dis- appointment to Mr. Robert Weldon, one of the com- petitors. He owned a luxurious 20 h.p. Armstrong Siddeley saloon, the performance of which entitled him to expect to win one of the coveted prizes. But his luck was against him. He never finished the course, owing to circumstances which were no fault either of the car or her crew. The task set to the competitors was this. They had to cover a course of approximately a thousand miles, at an average speed of twenty-five miles per hour. This course finished at Torquay, where subsequently a series of tests to determine the efficiency of the compet- ing cars was held. The competitors were distributed over nine separate starting points, and each was allot- ted his own time to start. To Bob Weldon was as- signed the official number 513. His task was to leave Bath at 8.45 p.m. on Tuesday March 1st, and proceed to Torquay via Norwich, Kendal, Droitwich and Moor- chester. At each of these towns controls were estab- lished, where competitors had to produce their route books, sign them, and have them stamped. Since the shortest possible distance by this route was 1005 miles, Bob Weldon's finishing time at Torquay was 12.57 2 DR. PRIESTLEY LAYS A TRAP p.m. on the 3rd. All went well at first. Bob had taken a pretty effi- cient crew with him. Richard Gateman, an old friend of his, was acting as second driver. Since a map- reader was also desirable, Richard had suggested an acquaintance of his, Harold Merefield, and Bob had fallen in with this suggestion. The three of them started from Bath at the appointed time, and ran steadily enough for the first twenty-four hours, keep- ing well ahead of the schedule which they had pre- pared. But their luck turned shortly before midnight of the 2nd, when they were about two thirds of the way be- tween Droitwich and Moorchester. They ran into a bank of fog, which seemed to fill the valleys with a sort of fluid cotton-wool. Their speed dropped at once, and on several occasions the car had to be stopped while Harold got out and tried to decipher the signposts with his torch. Eventually they lost their way completely, and spent much valuable time in getting back to the right road. They left the fog-belt behind at last, but the experi- ence had told upon all of them. This was their second night on the road, with only such snatches of sleep as they could get by turns in the back of the car. Bob was driving; Harold, schedule in hand, was sitting be- side him; Richard, who had been relieved at the wheel a few minutes before, was dozing in the back. "How are we getting on?" asked Bob, without taking his eyes from the strip of illuminated road in front of him. DR. PRIESTLEY LAYS A TRAP 3 "Not very well, I'm afraid," replied Harold. "We lost a devil of a lot of time in that confounded fog. As far as I can make out we're still twenty miles or more from Moorchester, and it's long after four o'clock already." Bob grunted. "What fools we were to take this job on!" he ex- claimed. "If this is your idea of pleasure, it isn't mine. I'm pretty well played out, but Richard's no better, so there's no point in changing over again. What time were we due at Moorchester?" "Two twenty-five," replied Harold. "We're running something like a couple of hours behind time." Bob's reply was to press gently on the accelerator. Tired out as he was, nothing would have induced him to give up. The speedometer needle crept over the dial as the car gained speed, till she settled into her stride at something over fifty miles an hour. This was the utmost speed at which Bob dared to travel, even on the straight stretches. A few thin wisps of fog still hung about, appearing like puffs of steam in the beam of the headlights, and the frequent bends in the road made it necessary to slack up every half mile or so. Neither of the two in front felt inclined for conversa- tion. Bob's whole attention was concentrated upon the road in front of him. Only by a supreme effort of will could he keep at bay his overmastering desire for sleep. An instant's relaxation, and he found himself plunging headlong into the void of unconsciousness. Harold, free from the responsibility of driving, and lulled by the luxurious movement of the car, dozed fitfully. At 4 DR. PRIESTLEY LAYS A TRAP one moment he saw the road in front of him, white and unreal, like the highway of a dream. At the next his eyelids had closed of their own weight, only to start open as his subconscious self reminded him of his duty to watch the route and direct the driver if necessary. At last, after an interminable period, as it seemed, a faint glare began to soften the darkness ahead. Lamp-posts began to appear, and they felt rather than saw that scattered houses fringed the road on either side of them. The road became a street, the silent and unlighted houses flanking it like endless walls. Bob slackened speed, and turned sharply as a painted board "To the R.A.C. Control" caught his eye. A couple of minutes later he pulled up in the courtyard of the Im- perial Hotel. Several cars were standing in the courtyard, pre- sumably belonging to the control officials. None of them bore the flag and official number which showed that they were competing in the Rally. All these must have passed through long ago, and by now were well on their way to the finishing point. Harold noted this at a glance, then shouted over his shoulder: "Wake up, Richard! Moorchester control!" Urging their weary limbs to action, they descended from the car and entered the hotel. In a comfortable room reserved for their use, they found a group of con- trol officials. Richard blinked in the brilliant illumina- tion and looked about him. "My word!" he exclaimed. "I like the way you fel- lows make yourselves comfortable in the best pub in the town, while we go hurtling across England. Any DR. PRIESTLEY LAYS A TRAP 5 chance of a drink? I'm dying of thirst." The officials laughed. "You're number five thirteen, I suppose?" said one of them. "We were wondering what had become of you. There's some cold tea on that table over there if that's any good to you." "Oh, never mind him," interrupted Bob impatiently, as he came forward, route book in hand. "He'll stay here all night, if you encourage him. And we haven't a minute to spare." "You've only just saved your bacon, as it is," re- plied the official, glancing at the clock. "The control closes in ten minutes, and then we are off home to bed. All the other Bath cars are through. What happened to you? Did you have a breakdown, or something?" "Breakdown?" said Bob scornfully. "No, fog; ran into it about midnight and couldn't get clear. We'd have been here hours ago, but for that. Still, we'll do it all right if we don't strike another patch." He signed the book with shaking fingers, his usually firm and bold signature looking like that of an old man. The other two, their fingers numb with sleep, followed his example. The official stamped it with a rubber stamp, and handed the book back to Bob. "Off you go; and better luck to you on this stage," he said. Outside in the courtyard they held a hurried council of war. "It's now three minutes past five," said Harold, con- sulting the schedule. "We're two hours and forty min- utes behind time. We're due at the finishing line at DR. PRIESTLEY LAYS A TRAP 7 themselves into the same positions as before. Bob glanced at the gauge. "We've enough for a hundred miles," he replied. "We'll stop at the first garage we see open after it's light." He flicked the pre-selective gear with his fin- ger, and touched the clutch pedal. The car glided softly out of the courtyard, and began to gather speed. "Five five," remarked Harold, as he pencilled in the time on his schedule. "Good enough!" exclaimed Bob. "Bar accidents, we'll be in Torquay to the minute, and have time for breakfast on the way, into the bargain. You see if we don't." The few minutes at the control and the mouthful of coffee he had swallowed seemed to have roused Bob for a while. He swung the car through the deserted streets of Moorchester, until he gained the open road, the bon- net of the car pointing westward. It was pitch dark, with only a few frosty stars twinkling overhead, but mercifully a faint breeze had sprung up, driving before it the last vestiges of fog. The steady beam of the headlights shed a hard, cold ray upon the road ahead of them. It could not be described as a fast road. For the first few miles out of Moorchester it was narrow and winding, with an irritating succession of sharp corners, necessitating constant checking of speed. But the car responded nobly to Bob's driving. The brakes acted smoothly but powerfully; at a touch on the accelerator pedal, the car gathered speed again like a live thing. At last the road seemed to make up its mind to keep a 8 \ DR. PRIESTLEY LAYS A TRAP constant direction. It became comparatively straight, running like a ribbon across a stretch of flat country, with deep ditches on either side. Bob took advantage of this at once, and the speed- ometer needle settled at a steady sixty. But it was obvious that he had come to the end of his tether. More than once the car edged towards the grass alongside the road, to be corrected by an almost convulsive clutch at the wheel. Harold endured this as long as he could, but at last, when the near wheels actually mounted the grass, he could not contain himself any longer. "Steady, Skipper!" he exclaimed. "You'll have us in the ditch if you're not careful." "Sorry," said Bob dreamily. "I'm so tired I can hardly keep my eyes open. The only things I can see are the trees by the side of the road, and they persist in making faces at me. Give Richard a hail, and as soon as he's properly awake he can take over." Harold was about to turn his head for the purpose, when he caught sight of something in the road ahead of them. "Look out!" he said. "There is a red light in front there, the road's up, as likely as not." Bob nodded. "I see it," he replied. Harold turned to wake Rich- ard, a feat which he accomplished with some difficulty. By the time he was facing the road again, the car had slowed down, and the red light was no more than a hun- dred yards or so ahead. "Hallo!" he exclaimed. "That's the rear light of a car. And, by Jove, he's in the ditch, by the look of it." DR. PRIESTLEY LAYS A TRAP 9 Bob pulled up the Armstrong Siddeley a few yards from the red light, which seemed to glower at them like some evil eye. "He's in the ditch all right," he said. "We'd better have a look, I suppose, before we go on." There was no doubt about the car being in the ditch which, as Harold had already noticed, was particularly wide and deep. The car had apparently swerved to the right, the off front wheel was right in the ditch, and the near front wheel was just on the edge of it. The car had not overturned though it had a dangerous list, only the rear part remaining on firm ground. The crew of the Armstrong Siddeley got out and hurried towards the derelict. "Hallo!" exclaimed Bob. "It's a Rally car. The flag is still fixed to the radiator cap. A two-seater sports Comet, by the look of it. Did anybody think of bringing a torch along?" The torch was obviously necessary. Although the rear light was still burning with an ominous red glow, the side and headlights were smashed, and nothing in front of the car could be seen. Harold produced the torch, walked a couple of yards up the road, and turned the light on to the radiator of the Comet, revealing a plate with the official number 514. "Hallo, the next number to us!" exclaimed Bob. "He must have started from Bath after we did. I won- der what's become of the driver and his passenger?" "I remember the car now," said Richard. "It was standing next to us in the starting park. There were two fellows in it, and I remember thinking that they'd 10 DR. PRIESTLEY LAYS A TRAP be jolly miserable before they finished, in an open car like that. I expect—" But he was interrupted by a horrified cry from Har- old. "Good Lord, look there!" The beam of his torch was directed upon a point on the further side of the ditch, about a couple of yards beyond the radiator of the Comet. The beam moved to and fro in his shaking hand, and it was a second or two before the others understood the cause of his ex- clamation. Then, simultaneously, they made out the figures of two men, lying in horribly contorted posi- tions between the ditch and the hedge beyond it. A sudden sense of disaster shocked them into instant wakefulness. Richard, the most agile of the party, took a running jump at the ditch and cleared it. The others followed him more deliberately. As Harold threw the light of his torch upon the nearest figure, they started back instinctively. His leather coat was covered with blood, and a dark patch spread over the grass round the upper part of his body. Fragments of broken glass scattered round about told their own story. "He must have gone straight through the wind- screen," said Bob, in a shaky voice. "Poor chap! Is there anything to be done for him?" Harold, who had some knowledge of medicine, put his fingers hesitatingly upon the wrist of one out- stretched arm. After a second or two he shook his head. "He's gone, I'm afraid," he replied. "Look at the blood he's lost." DR. PRIESTLEY LAYS A TRAP 11 "What about the other fellow?" asked Bob, his voice sounding harsh and broken. The second man, also wearing a leather coat, lay, like the first, on his face. Though he also was spat- tered with blood, no pools of it lay round him. But he showed no sign of life, and once more Harold shook his head. "He doesn't seem to be cut about like the other one," he said. "More likely his neck was broken when he was thrown out." "Well, it's all pretty ghastly," remarked Richard. "It's plain enough what happened. The driver went to sleep, and ran off the road when he was travelling at high speed. I suppose we'd better get these poor chaps into the Armstrong, and find the nearest hospital." "I don't think we can do that," replied Harold hesi- tatingly. "I'm pretty sure there's nothing to be done for either of them, and if they're dead we mustn't touch their bodies." "Then it's a job for the police," said Bob with deci- sion. "Where the devil are we? I've lost count of time and direction." Harold produced a map from his pocket and con- sulted it by the light of his torch. "I reckon we've come about fifteen miles out of Moor- chester," he said. "If that's so, there's a place called Westernham about three miles ahead." "I've driven through it," replied Bob. "It's a small market town, and there's bound to be a police station there. Look here, Richard, you're the freshest of us. Take Harold with you and drive like the devil. I'll CHAPTER II "What a beastly thing to happen!" exclaimed Richard when they were well under way. "I can quite under- stand it, though. I've driven one of those Comets my- self, and they're none too easy to keep on the road when they're travelling really fast." "And those two fellows can't have had much sleep in an open car like that," replied Harold. "It's been quite different for you and the Skipper. You've both had an hour or two of comfort in the back of this most luxurious car. What's more, she practically steers her- self. Yet all the same, I don't mind telling you that the Skipper frightened me more than once as we came along just now." "One nod on a Comet, and you're off the road. That's what happened, beyond a doubt. It's queer that they went off on the right hand side, though. The in- stinct of most English drivers, at least, is to pull in towards the left. They must have been travelling some, when it happened. Did you notice that the whole front axle was knocked right back?" Harold made no reply. He was intent upon watch- ing the road. They seemed to be nearing a town. A pavement sprang up to one side of them, and the glare of the headlights was reflected in the windows of houses ahead. A big notice board appeared: "Westernham. Narrow streets. Please drive slowly." 13 14 DR. PRIESTLEY LAYS A TRAP Before they had gone much further, they saw a blue lamp burning over the door of a severe looking build- ing. "That'll be the police station," said Richard as he pulled up. "Slip out, and see if there's anybody about." Harold descended from the car. As he did so, he noticed that the ebony darkness through which they had driven for so many hours had softened to a dull grey. Objects were becoming dimly visible, seeming monstrous and misshapen. The stars were no longer bright and hard, and seemed less plentiful. Those that remained showed as pale and sickly points in the sky. He mounted the steps leading to the police station, and rang the bell. A muffled clangour, harsh and threatening, rang out inside the building. Then there was silence, intensified by the utter stillness of the sleep- ing town, until at last it was broken by the sound of Richard's footsteps as he joined his friend. "Seems as if the local constabulary were plunged in slumber," he remarked. "Looks like it," replied Harold. "Hold on, though, I believe I hear somebody moving about inside." They listened, and a sound as of heavy boots pacing a stone passage came to their «ars. There was a groan of a bolt, and the door was flung open, revealing a mas- sive form in shirt sleeves. "Well, and what do you gentlemen want?" asked a deep bass voice. "There's been an accident on the road, about three miles from here," replied Richard. "A car in the ditch, and the driver and passenger killed, by the look of it. DR. PRIESTLEY LAYS A TRAP 15 One of the Rally cars; the driver must have gone to sleep—" His voice trailed off as he caught the policeman star- ing at him curiously, then he realized that he was sway-" ing as he stood, and made a spasmodic effort to steady himself. "An accident, eh?" said the policeman suspiciously. He came a step nearer, and began sniffing, as though suddenly afflicted with a violent cold. "I should like to see your driving licence, please," he said sharply. "It's in the car," replied Richard; and then, as the absurdity of the policeman's action dawned upon him, he laughed mirthlessly. "We're not drunk, only dog- tired," he explained. "We were competing in the Rally too, and we've been some thirty-three hours on the road. None of us have tasted a drink since we started, I can promise you that." "Oh! so that's it!" exclaimed the policeman, some- what mollified. "Well, some folks have queer ways of enjoying themselves; that's all I can say. Did you see this accident happen?" "No, we didn't," replied Richard wearily. "We saw the car by the roadside, and stopped to investigate. But hadn't you better come and see for yourself? You can ask all the necessary questions later. We'll run you to the spot." The policeman grinned. "Perhaps you're right," he said. "Come inside a minute while I get my coat and telephone to the doc- tor. You're sure the people you saw were dead, and not merely stunned?" 16 DR. PRIESTLEY LAYS A TRAP "I had a look at them without disturbing them in any way," said Harold. "I couldn't find any signs of life about them." The policeman nodded, and disappeared through a doorway. They heard his voice as he used the tele- phone in the charge room. Then he came back, fully clad, and they saw that he wore a sergeant's stripes. And to Harold's astonishment, he had a camera in his hand. "I'll have your names, please, gentlemen," he said, producing a notebook. "Mine is Showerby, Sergeant Showerby, of the County Police. I've rung up Dr. Mason, and asked him to come along. He'll be here in his own car in a minute or two. Mr. Richard Gate- man? Thank you. And yours, sir? Mr. Harold Merefield? And which of you gentlemen is the owner of this car?" "Neither of us," replied Richard. "We've left the owner with the other car, the one that's had such a smash." It seemed to Richard that the sergeant's eyebrows lifted for an instant. "And what is the gentleman's name?" he asked. Richard told him, and he closed the notebook and re- placed it in his pocket. "That will do for the present," he said. "We had better get into the car, so as to be ready for Dr. Mason when he comes." Richard and Harold walked out to the Armstrong and got in. "Jump in at the back, Sergeant," said the former. DR. PRIESTLEY LAYS A TRAP 17 "I'll turn her round ready to start when the doctor comes." But Sergeant Showerby seemed to be in no hurry. Instead of getting in by the door nearest to him, he walked slowly round the car, staring at it as though a motor was a wholly unfamiliar form of transport. "What's he up to?" asked Richard impatiently, his foot on the clutch pedal. "Looking for the damage," replied Harold softly. "He suspects us of having run into the other fellow! Haven't you spotted that yet? You can't blame him; he's only doing his duty." At that moment the sergeant opened the door and climbed in. Richard reversed the car, and for a few minutes they waited in silence. Then the lights of a second car shone out behind them and drew alongside. The sergeant leant out of the window. "That you, Doctor? Well, will you follow us? These gentlemen say it is about three miles along the road." "All right, go ahead," replied Dr. Mason. The Armstrong started off, closely followed by the other car. The three miles were covered in silence, and ■ Richard pulled up beside Bob Weldon, who was wait- ing for them by the roadside. By now it was getting light, that deceptive half- light in which, though objects cannot be clearly dis- cerned, the most powerful headlights seem feeble and irresolute. The wrecked Comet, tilted at an unnatural angle, seemed utterly abandoned and forlorn. And beyond it were the two motionless figures in leather DR. PRIESTLEY LAYS A TRAP 19 "Official number five fourteen, entered by A. Lessing- ham. Yes, that's what the first signature looks like. I can't make out the other quite, but I think it is T. Purvis. They seem to have left Bath at nine p.m. on the first; that's the day before yesterday. Where did you gentlemen start from?" "We started from Bath, too," replied Bob. "Our official number is five thirteen, the next before theirs. We started at eight forty-five, a quarter of an hour in front of them." "And yet you found this car in the ditch as you came along?" said the sergeant quickly. "They must have been in front of you then?" "Of course they were," replied Bob with a hint of irritation in his voice. "You wouldn't expect us to keep the same distance apart over eight hundred miles odd, would you? We happened to be delayed by fog, and perhaps they escaped it." A new idea seemed to strike the sergeant. "You have a route book similar to this, Mr. Wel- don?" he asked. "Yes. Every competitor in the Rally carries one. Slip over to the car and fetch it, will you, Harold? It's in the cubby-hole in the front." Harold fetched the route book, and smiled as he saw the eagerness with which the sergeant inspected the names inscribed in it. Apparently satisfied that they corresponded with those he had already been given, he turned to the record of the Moorchester control. "Your time is given as four fifty-six a.m., this morn- ing," he said. "Mr. Lessingham's is given as four 20 DR. PRIESTLEY LAYS A TRAP thirty-two a.m. He was twenty-six minutes in front of you, then?" "You can't tell exactly. Those are the times at which the books were presented. They may not have left immediately afterwards. Though we signed in at four fifty-six we didn't actually leave till five five." "So that Mr. Lessingham's car may have been only a short time ahead of you? Not more than a minute or so, perhaps?" "It must have been a good deal more than that. It had left the control before we arrived there. No other cars with the Rally flag and number were in the court- yard of the Imperial Hotel." "But still you might have overtaken it between Moorchester and here?" persisted the sergeant. "I can only assure you that we saw.no sign of it in front of us until we found it as you see it," replied Bob firmly. Their conversation was interrupted by Dr. Mason, who rejoined them at that moment. "They're both dead," he said tersely. "One of them has a jagged gash right across the jugular, and must have bled to death in a very short time. I can't say off-hand how the other man died. He appears to have escaped the broken glass, and so far as I can see at present no bones are broken. Some internal injury, no doubt. They had better be taken to the mortuary, Sergeant, and I will communicate with the coroner." "Can you say how long they have been dead, Doc- tor?" asked the sergeant, taking out his notebook once more. DR. PRIESTLEY LAYS A TRAP 21 "Not to within a few minutes, naturally," replied Dr. Mason. "Somewhere round about an hour, I should think. The indications seem to show that the man with the gash in his throat died first, if that's any good to you. I can't do any more here, and I'm off back home. I'll see you later on in the morning." Harold looked at his watch as the doctor was speak- ing. He stared at it for an instant, then held it to his ear. No, it had not stopped. Yet it was incredible that the time should be no later than twenty minutes past six. Only an hour and a quarter since they had left Moorchester! It seemed an eternity! He nudged Richard and showed him the watch. Obviously Rich- ard was equally incredulous. He fumbled in his pocket and produced his own. The two watches agreed to the minute. "By Jove, I thought it was hours later than that!" he muttered. "I say; we might do it yet!" Then he turned to the sergeant. "Anything more we can do for you, Sergeant?" he asked nonchalantly. "If not, we'd better be getting along." Sergeant Showerby's lips widened in a grim smile. "I'm afraid I shall have to ask you gentlemen to stay here for the present," he replied. "One moment, Doctor. Would you mind calling at the police station on your way home, and asking them to send a constable out here on a bicycle at once?" Dr. Mason nodded, got into his car, and drove away. By this time it was really light. The eastern sky was flecked with pink, and the stars had completely disap- peared. For the first time Sergeant Showerby was DR. PRIESTLEY EAYS A TRAP able to observe the group that stood before him. It struck him that their appearance was scarcely prepossessing. Their unshaven faces were haggard and drawn, stained with the grime of the fog through which they had passed. The heavy coats and mufflers which they wore did not improve matters. Bob Wel- don was the eldest, a man of forty-five, or thereabouts, with a shrewd, half-humorous expression. Richard Gateman, between thirty-five and forty, was slighter and shorter. He wore glasses, and his expression was one of eager alertness. He moved restlessly, as if the whole affair bored him, and he longed to be done with it. Harold Merefield, the youngest of the party, was tall and powerful, but had the face of a man who spends most of his time indoors. The sergeant's face as he glanced at them each in turn was inscrutable. "I should like to see your driving licences, please," he said. Bob and Richard produced theirs, and the sergeant noted the particulars in his book. Then he turned to Harold inquiringly. "Sorry, I haven't got a licence," said Harold. "I wasn't driving, merely time-keeping. You'll have to take me on trust, unless you'd like to ring up my em- ployer." "We'll see about that later," replied the sergeant curtly. "Now your occupations, please?" "Manufacturer," said Bob Weldon. "I own a pot- tery works at Clayport—Weldon & Company." "And I suppose I can be described as a manufac- DR. PRIESTLEY LAYS A TRAP 23 turer's agent, can't I, Skipper?" said Richard. "I manage Mr. Weldon's London office for him, in Upper Thames Street." The sergeant took down these particulars, and glanced at Harold. "Secretary," said the latter. "My employer's name is Dr. Priestley, and he lives in Westbourne Terrace, London." Evidently the sergeant was a man of method. He next noted the registered numbers of the cars. That of. the Armstrong was QK 1773, and of the wrecked Comet ZV 9694. Once more he examined the Arm- strong Siddeley closely, then turned his attention to the Comet. The damage to the latter was now clearly apparent. The impact of striking the further side of the ditch had bent both dumb-irons, and driven the front axle hastily back towards the gear box. The radiator was appar- ently undamaged, but only a few jagged spikes of glass remained where the windscreen had been. So far as could be seen from the road, there was no blood in- side the car, but the bonnet was spattered with drops. One of the spokes of the steering wheel was broken, and the column was bent forward. The front seats had fallen from their normal position, and were lying on the floor beneath the dash. The rear portion of the car was undamaged. While the sergeant was noting these details, the fig- ure of a policeman on a bicycle appeared from the di- rection of Westernham, pedalling furiously towards them. He dismounted, breathing heavily, and saluted. 24 DR. PRIESTLEY LAYS A TRAP Sergeant Showerby took him aside, and gave him a few brief instructions in a low tone. The sergeant then opened his camera. The sun had risen by now, and, though the shadows were still long, the light was at least passable. He took several photo- graphs of the wrecked car, and of the bodies lying in front of it, trying to get his pictures from as many dif- ferent points as possible. Then he turned his atten- tion to the road itself. During the night a certain amount of dew had fallen, covering the smooth surface of the Tarmac road with a thin film of moisture, which was already beginning to disappear in thin vapour under the sun's rays. But enough remained to show distinctly the wheel tracks of the Armstrong and the Comet. The former, being the most recent, were the clearest. They led up to the scene of the tragedy in a fairly straight line. Only occasionally did they trend gently towards the left- hand side of the road and back again. In several places they crossed the tracks of the Comet, which were thus obliterated at these points. Finally, they showed no trace of skidding, or of the wheels having locked, where the car first drew up, showing that the brakes had been applied normally. Up to about thirty yards from its present position, the Comet had left very similar tracks. They were even straighter than those of the Armstrong, running without deviation along the centre of the road. But suddenly this regularity ceased. For a few yards the front wheels had left a serpentine track, as though the steering wheel had been wrenched violently first in one DR. PRIESTLEY LAYS A TRAP 25 direction, then another. Finally, the steering wheel seemed to have been turned hard over, and the tracks led abruptly to where the car stood now. And, throughout the whole of these contortions, there were marks where the wheels had been momentarily locked and then released. Sergeant Showerby changed the spool in his camera, and took a series of photographs of the tracks. This done, he turned to the waiting group, on which the con- stable had been keeping a watchful eye. "I'm sorry to have kept you waiting, but I thought it best to take these photographs in your presence," he said weightily. "It will, I am afraid, be necessary for you to remain at Westernham for the present. You all appear to need a rest, and if you will get into your car, the constable will show you the way to the White Hart where I am sure you will be quite comfortable." Under other circumstances they might have ques- tioned Sergeant Showerby's authority for disposing of them thus summarily. But, as things were, there seemed no alternative to compliance. By the time they could appeal to the sergeant's superior, it would be far too late to continue their journey with any hope of ar- riving within the specified time. They all realized this, and resigned themselves to the prospect of the White Hart. After all, sleep was what they all craved, and here was a chance of getting it. Without protest, they entered the Armstrong, taking the constable with them. Under his guidance, they reached the hotel, where they made the just-roused staff understand that they wanted a wash, and some place where they could sleep undisturbed. CHAPTER III Bob Weldon was the first to wake. He did so with a start. How was it that the car was not moving? Had they reached a control? Then as he opened his eyes, he saw that he was lying on a bed in an unfamiliar room, and recollection of the events of the early morn- ing returned to him. A chambermaid, a stolid girl who looked as though nothing was likely to perturb her, was standing by his bedside. "Beg pardon, sir," she said as soon as she saw that Bob was awake. "There's a police inspector asking for you downstairs. He says he'll come up here if you don't want to go down." "Oh, I'll go down," replied Bob hastily. "What time is it?" "Just gone one, sir, and there's some lunch on in the coffee room if you'd care for it." "Just gone one!" He would have been over the finishing line at Torquay, if this confounded business had not interfered with his plans. For an instant he regretted the impulse that had led him to pull up and investigate the ditched Comet. But the thought of its occupants flung out lifeless beside it recurred to him. He could not have gone on and left them untended. "Lunch," he said. "Yes, rather! I'll have some as soon as I've finished with this inspector chap. Tell them to keep me some at all costs. And if you're going 26 DR. PRIESTLEY LAYS A TRAP 27 down you might tell the inspector I shall be with him in a couple of shakes." The chambermaid departed and Bob sprang out of bed. He had only thrown off his outer garments, and he was quickly dressed. As he caught sight of his face in the mirror he paused. He was certainly a ghastly spectacle. Why shouldn't his visitor wait while he had a shave? No, better not, perhaps there would be time for that later. He walked downstairs with legs that had a curious feeling as though they did not belong to him. As he reached the hall, a tall, pleasant-faced man of about his own age came towards him. "Mr. Weldon?" he asked. "I am Inspector Harra- way from Moorchester. I am very sorry to disturb you, but I am anxious to obtain information regarding the accident which happened to Mr. Lessingham's car this morning." "I should have thought that Sergeant Showerby could have given you full particulars," replied Bob. "He asked enough questions last night—or rather this morning. Still, I'm ready to tell you all I know. Is there anywhere here where we can sit down and talk?" "The landlord says we may use his office," replied Inspector Harraway. "There's nobody there at this time of the day, and we shan't be disturbed. It's just through here." He led the way to a small but comfortably furnished room, and the two seated themselves. "I'm afraid that you must have thought Showerby a trifle officious," began the inspector, apologetically. 28 DR. PRIESTLEY LAYS A TRAP "But you must realize that he was bound to collect what information he could, and to take every possible precaution. He's really a most intelligent and pains- taking man, and a very good fellow at heart." "I'm sure he is," agreed Bob dryly. "I had evidence of his thoroughness, anyhow. I wouldn't have minded if he hadn't so obviously suspected us of being responsi- ble for the smash." Inspector Harraway smiled. "He was bound to consider the possibility, you know," he replied. "In fact, I think he's still got it at the back of his mind that your car had something to do with it. Now, I'll be perfectly frank with you, Mr. Weldon. For my own part, I don't believe for a mo- ment that you know anything of the cause of the acci- dent. But I'm bound to make certain inquiries. In the first place, I want to be quite clear as to the details of this Rally. As I understand it, each competitor had to cover a distance of approximately a thousand miles at an average speed of twenty-five miles an hour. Both you and Mr. Lessingham started from Bath during the evening before last." Bob nodded. "That's right," he agreed. "Competitors were given the choice of nine starting places. They had to start between six and nine o'clock, and each was allotted a separate starting time. Our time was eight forty-five, p.m., and we were the last but one to start from Bath. The Comet followed us at nine o'clock." "I gather that your course was marked out for you, and that you had to report at various controls en DR. PRIESTLEY LAYS A TRAP 29 route?" "We had to report at Norwich, Kendal, Droitwich, and Moorchester, in that order. Competitors starting from other points had a different set of controls. But, as long as we reported at those controls, we were free to choose the route to follow between them. No doubt different drivers chose different routes." "I see. Just one more point, Mr. Weldon. Each competitor was given a route book on starting, which he had to produce at each control to be stamped with the time of his arrival?" "Exactly. When the route book was produced, all the occupants of the car had to sign it in the presence of the officials." "Thank you, Mr. Weldon. Now, I have been com- paring your route book with Mr. Lessingham's, and there are certain discrepancies which perhaps you can explain. I have made a summary of them on a piece of paper. Here it is." The inspector handed Bob a piece of paper, drawn up as follows: Control 513 (Weldon) 514 (Lessingham) Bath 8.45 p.m. (1st) 9 p.m. (1st) Norwich 3.12 a.m. (2nd) 3.21a.m. (2nd) Kendal 12.07 a.m. (2nd) 9.52 a.m. (2nd) Droitwich 7.31p.m. (2nd) 4.02 p.m. (2nd) Moorchester... 4.56a.m. (3rd) 4.32a.m. (3rd) "Now," continued the inspector, "there are one or two things I can't quite make out. On the first section, from Bath to Norwich, you and Mr. Lessingham seem 80 DR. PRIESTLEY LAYS A TRAP to have kept your relative positions. He started fifteen minutes later than you and arrived nine minutes later. That means that you both travelled at about the same average speed?" "Probably we did," replied Bob. "Our route from Bath to Norwich was two hundred and eight miles by speedometer. We took six hours and fifty-seven min- utes to cover this distance. Got a pencil and a bit of paper on you?" The inspector tore a leaf out of his notebook, and handed it over, together with a pencil. Bob did a rapid calculation. "That works out at an average speed, in- cluding stops for traffic, change of drivers, and petrol, of thirty miles an hour. That's what we were aiming at. We meant to travel at that average speed through- out the trial." "It was not in any sense a speed test?" inquired the inspector. "Only in so far as the average speed had to be main- tained. There was no point in driving too fast. Com- petitors were penalized if they crossed the finishing line more than five minutes before their time." "You say that you intended to maintain an average speed of thirty miles an hour, Mr. Weldon. Mr. Les- singham seems to have started with the same intention. But during the second stage of the journey, your times begin to vary. He arrived at Kendal two hours and a quarter before you. How do you explain that?" "I can explain it best if I fetch our schedule, which is in the car," replied Bob. "Will you excuse me for a moment?" He went to the hotel garage, into which he DR. PRIESTLEY LAYS A TRAP 31 had driven the Armstrong that morning, and brought back with him a board on which was pinned a piece of paper. "This is a table of times and distances, prepared be- forehand," he explained. "You will see that it shows the distances between important points on the route, with the times at which we should pass them if our aver- age speed is maintained. In pencil against these fig- ures is marked our actual time. You will see that we arrived at the Norwich control at three twelve, which is the time registered in our route book. But we did not leave at once. We had some hot coffee, and filled up with petrol. This took us fourteen minutes, and we did not leave Norwich till three twenty-six. Then again we had breakfast at Doncaster, which took thir- ty-seven minutes. The route book shows eight hours and fifty-five minutes between Norwich and Kendal, but fourteen minutes plus thirty-seven minutes, or fifty-one minutes, must be deducted from this. This stage was two hundred and forty-nine miles by speed- ometer, and we covered it in eight hours, four min- utes, actual running time. Let me work that out. Thirty-one miles per hour near enough. "Now, Mr. Lessingham possibly did not stop long at Norwich, or for breakfast en route. If we allow him ten minutes off his route book time, he covered the dis- tance in six hours, twenty-one minutes, or at the rate of thirty-nine miles per hour. It is pretty good going, but not beyond the powers of a sports car, built for speed, especially as he had daylight for more than half the way. In fact, I dare say we could have done it 32 DR. PRIESTLEY LAYS A TRAP ourselves, had we wanted to." "I'm much obliged to you for your information, Mr. Weldon," said the inspector, as he pored over the sum- mary he had made. "Mr. Lessingham seems to have pushed on as fast as he could. But what was his object, since you have just told me that he would be penalized if he arrived at Torquay before his time?" "By the look of his route book figures, he intended to get as far ahead as possible by yesterday evening," replied Bob. "I know that this was the intention of several of the competitors. Their plan was to snatch a few hours' sleep at Moorchester last night. Look here; he seems to have taken over twelve hours between Droitwich and Moorchester, a hundred and eighty-six miles, by the route we took, which is absurd. We were held up by fog, and lost over two hours in consequence, but we took less than nine hours and a half." "You think it possible that Mr. Lessingham slept at Moorchester last night?" asked the inspector quickly. "I think it extremely probable. Judging by his average speed over the previous stages, he should have arrived at Moorchester about ten or eleven o'clock last night. The Moorchester control did not open till twelve forty-two a.m., this morning, so he could not present his route book then. He probably took a room at some hotel, slept till half past four, then presented his book for stamping, and started off at once. He would have plenty of time. Since he started from Bath fifteen minutes later than we did, his finishing time at Torquay would be correspondingly later, or one twelve p.m., today. He thus had eight hours and forty min- DR. PRIESTLEY LAYS A TRAP 33 utes in which to cover approximately two hundred and thirty miles, an average of twenty-six and a half miles per hour." But the inspector's attention seemed to have wan- dered. He made no comment upon Bob's calculation, but sat for a moment frowning thoughtfully. "What is your explanation of the accident that hap- pened to Mr. Lessingham's car, Mr. Weldon?" he asked suddenly. "Why, it seems simple enough to me," replied Bob. "The driver went to sleep at the wheel, and the car ran into the ditch. That very nearly happened to me on the same stretch, as Harold Merefield, who was sitting beside me, can tell you." Inspector Harraway nodded, and looked at his watch. "Why, it's half past one!" he exclaimed. "You must be very hungry, Mr. Weldon. I don't suppose you had much time for food while you were driving?" "I haven't had a decent meal since breakfast yester- day," replied Bob. "I told the people here that I should have lunch as soon as you had gone." "How thoughtless of me! I would not have kept you from your lunch for the world. For that matter, I am feeling a bit peckish myself. How would it be if we went into the coffee room and had lunch together?" Bob agreed to this readily enough. They adjourned to the coffee room, where they chose a table at which their conversation would not be overheard by the other occupants of the room. The meal having been ordered, the inspector began to talk in a conversational tone. DR. PRIESTLEY LAYS A TRAP 35 "Yes. I suppose four hours' sleep would be sufficient to refresh anybody. By the way; you remember those photographs Sergeant Showerby took? They came out wonderfully well. Photography is Showerby's hobby, and he's awfully keen on it. He married the sister of the local photographer here a year or two back. I don't know whether the hobby was responsible for the marriage or the marriage for the hobby. Anyhow, these photographs are excellent. He showed me the negatives, and he's having them printed by his brother- in-law this afternoon. You ought to get him to show them to you when they are ready. The ones he took of the tracks of Mr. Lessingham's car are particularly good. But since you saw the actual tracks for your- self, perhaps you wouldn't be as interested as I am." It dawned upon Bob that the inspector had been watching him closely throughout this apparently irrel- evant conversation. He frowned slightly, as he realized that there was something behind it, which he had not perceived. "Look here, Inspector Harraway," he said quietly. "As one man to another, would you mind telling me exactly what it is you're getting at?" The inspector smiled. "I was hoping that you would see that for yourself," he replied. "You told me just now that you believed the accident to Mr. Lessingham's car to have been caused by the driver going to sleep at the wheel. From your own experience, you regard such a thing as quite possible. But there is one thing you have quite over- looked. You say that you are perfectly fit to drive now 36 DR. PRIESTLEY LAYS A TRAP after four hours' sleep. But Mr. Lessingham and his passenger, if your deduction from his route book is cor- rect, had at least that amount of sleep at Moorchester." Bob whistled softly. "If they had, it is not in the least likely that they went to sleep fifteen miles out," he said. "Exactly. But until we have verified that they did actually get this sleep, we cannot base any argument upon it. But there's another thing. Imagine yourself driving Mr. Lessingham's car with Mr. Gateman be- side you. You are feeling very sleepy, and constantly doze off. What would happen?" Bob laughed. "I can tell you exactly what did happen in my car this morning," he replied. "More than once I did doze off for a fraction of a second. On the last occasion I did not recover my senses till the wheels of the car were actually on the grass. I dare say it was the slight jolt that wakened me." "On which side of the road did you go on to the grass?" "On the left. It's one's natural instinct. It's curi- ous that the Comet should have gone in on the right." "That's one of my points. Imagine that you were in that car, dozed off, and didn't wake in time. What would have happened then?" "If Richard had been beside me, and awake, he would probably have snatched the wheel and got the car back on the road before we hit the ditch. If he had been asleep, we should have gone into the ditch as the Comet did." DR. PRIESTLEY LAYS A TRAP 37 "In that case, what would be the appearance of the wheel tracks of the car?" "They would have shown a gradual tending towards the left, until the car came to a stop in the ditch." "That is just my opinion, and I am very glad you have confirmed it. If you will recall the appearance of the tracks of Mr. Lessingham's car, you will remember that they were very different. Before the car took the final swerve to the right into the ditch, there was a very well marked wobble from side to side. And as soon as that wobble commenced, the brakes were applied. Is it possible that the application of the brakes caused the wobble and the final swerve? I should like your opinion as an expert driver." "I suppose it would be possible if the brakes were very badly out of adjustment," replied Bob thought- fully. "I have known cases of cars with badly adjusted brakes, tending to one side or another when the brakes were applied. But I can't imagine any adjustment be- ing so bad as to cause the extreme wobble and the sud- den swerve that the tracks showed. There was no question of a skid. The tracks showed no sideways movement of the wheels." "Did you form any theory to account for the be- haviour of the car, as shown by the tracks?" "I can't say that I did. For one thing I was too sleepy, and for another I took it for granted that the driver had gone to sleep, and didn't think any more about it. But now after what you've said, I see the ob- jections to that. The only thing I can think of is that the driver somehow lost control of the steering wheel CHAPTER IV Lunch over, Bob went upstairs and looked into the rooms occupied by Richard and Harold. They were sleeping like logs, and it seemed a pity to disturb them. He shaved and made himself look more presentable, and then rejoined Inspector Harraway in the hall. They got out the Armstrong. Bob regretfully re- moved the Rally flag and official number and they started off in the direction of Moorchester. The in- spector sat beside Bob, very much on the alert. "There's nothing much the matter with your driving now, whatever it may have been like early this morn- ing," he said. "But my object in asking you to take me out wasn't only to test that. I want you to help me with some inquiries in Moorchester, if you will. The control there was established at the Imperial Ho- tel; I know that. Where did competitors leave their cars while they were reporting?" "I don't know what the others did. We were so late that they had all gone on by the time we arrived. We parked in the courtyard, under the instructions of an R.A.C. man who was there. I expect the others did the same." "We'll try and find that R.A.C. man. He may be able to tell us when Mr. Lessingham arrived, and put us on his track. I'm very anxious to find out if he did actually put up anywhere in Moorchester last night." 39 DR. PRIESTLEY LAYS A TRAP 41 seater Comet sports, painted grey, among them?" "Yes, sir, there was. I remember it because it was the only open car there. The rest were all saloons." "Do you know when it left the control?" "Yes, sir. A lot more cars came in and drove away after I got there, but this particular Comet didn't move. In fact, I wondered what had become of the driver. About half an hour before the control closed it was the only competing car left. And then a couple of gentlemen came running out of the hotel, jumped into it, and started off. I heard one say to the other something about having overslept themselves. I thought that must be the last of the Rally cars, but quarter of an hour after these had gone, an Armstrong Siddeley, exactly like the one you're in now, sir, arrived at the control. Three gentlemen got out of it, went into the hotel, and came out again almost at once. I thought to myself that if they'd been a few minutes later, they would have found the control shut. I re- member the official number. It was five thirteen." "This is the very car," remarked the inspector. "It has been unfortunately prevented from finishing, the course. Don't you recognize either of us?" The R.A.C. man peered at Bob and the inspector. "I can't say that I do, sir," he replied. "It was very dark in the courtyard, and I couldn't well distinguish faces. It's bad luck that you weren't able to finish, sir." "Then you wouldn't recognize the gentlemen who got into the Comet if you saw them again?" asked the inspector. 42 DR. PRIESTLEY LAYS A TRAP "No, sir, I'm pretty sure I shouldn't. But they were both wearing leather coats, and the shorter of the two was at the wheel when they left the control. He started off as if he was in a terrible hurry, too." The inspector thanked the man for his information, and they drove on towards the town. "Your theory appears to be correct, Mr. Weldon," remarked Inspector Harraway. "I thought something of the kind must have hap- pened, when you showed me their control times," replied Bob. "They evidently arrived at the control before midnight, and went to sleep somewhere. Probably in the Imperial Hotel itself, since they left their car in the courtyard. I should try there first, if I were you." Again Bob proved to be on the right track. In- quiries at the Imperial Hotel revealed the fact that Mr. Lessingham had engaged a room there for the previous night. The letter in which he had done so was produced. It was headed "14 Cawdor Street, W.l" and was written in a careless, untidy hand. "Please reserve a room with two beds for me on the night of March 2nd. Aubrey Lessingham." "That's the address given on his driving licence, and the signature is similar to the one in his route book," re- marked the inspector aside to Bob. Then, addressing the reception clerk, to whom he was apparently well known, he said: "I'll keep this letter for the present. Now, can you tell me if Mr. Lessingham actually occu- pied the room?" "Oh, he occupied it all right. He and his friend. They were driving in the Rally, you know, and they DR. PRIESTLEY LAYS A TRAP 43 stayed here for a few hours to get some sleep." "Did you actually see them?" the inspector asked patiently. "No, I didn't see them myself. I left instructions with the chief night porter that they were to be shown into number two hundred and twelve. You see, I go off duty at ten o'clock, and they hadn't come by then. And by the time I got here at ten o'clock this morning they had gone. They paid the chief night porter, and he handed the money to me before he left this morning. The hotel was busy all night with people coming and going, he said." "I expect it was. Did the porter tell you what time they arrived?" "Oh, yes. Theirs was the first of the Rally cars that he was expecting to turn up. It was just about half past ten. Mr. Lessingham gave his name, and he showed them up to number two hundred and twelve. They looked very tired, he said; and they must have been, for they didn't wake when they were first called. It was like this you see, Mr. Harraway. They asked the porter to call them at a quarter to four, as they wanted to get away by four o'clock sharp. So he sent a man up to wake them then. He didn't think any more about it for a time; he was so busy with all those people continually coming and going, and wanting this and that. But half an hour later it occurred to him that he hadn't seen them about, and he sent up to their room a second time. Do you know, Mr. Harra- way, they had both gone to sleep again!" "Not altogether surprising under the circum- DR. PRIESTLEY LAYS A TRAP 45 idea. Itfs not a bad plan, but the objection to it is that it doesn't allow much margin for possible mishaps on the final" stage from here to Torquay." "Well, that's as may be. I think we've established that Mr. Lessingham and his friend did actually get a certain amount of sleep last night; and that, in my opinion, finally disposes of the theory that the cause of the accident was the driver going to sleep. Perhaps the experts will discover some defect in the car to ac- count for it. Meanwhile, I'm going to open this tele- gram. It may tell us something that we don't already know about Mr. Lessingham." He tore open the envelope, and took out the tele- graph form. Having read it, he handed it silently to Bob. It had been handed in at 6.12 p.m. on the 2nd, the previous day. The office of origin was South Ken- sington, and the message was as follows: "Lessingham, Imperial Hotel, Moorchester. Cannot meet you at Torquay as we arranged, love." "I don't know that that's particularly enlightening," remarked Bob, as he handed the telegram back, "ex- cept that it shows he had spoken beforehand of his in- tention of stopping at the Imperial Hotel, which you knew already from his letter." "Oh, it tells us a lot more than that," replied In- spector Harraway. "It tells us that the sender was a woman. For one thing, no man would put the word 'love' at the end of a wire. And there's another thing. The address and the message proper took eleven words. Now, nearly everybody likes to send twelve words, and so get full value for their shilling. But the average 46 DR. PRIESTLEY LAYS A TRAP person, having a word to spare, would add his name, Tom, Dick, or Harry. To put in the word 'love' is a regular woman's trick. I wonder if Mr. Lessingham was married? I don't think that there's much more we can do here, for the present. Suppose we get back to Westernham?" As they drove over the now familiar road, Bob could no longer restrain his curiosity. "It seems to me, In- spector, that you're spending a lot of time and trouble over this business," he said. "Do you always do this sort of thing in the case of a pure accident?" "Our instructions are to investigate very carefully the circumstances of any fatal accident," replied the inspector. "Besides, the coroner will want to know all about it, you may be sure. And, to be quite frank with you, Mr. Weldon, there are points about this particular accident that I don't understand. I'm hoping that the examination of the car may throw some light upon it." "Perhaps it will, and perhaps it won't," replied Bob doubtfully. "With the front of the car smashed up like that, it will be the deuce of a job to discover any defect which existed before the accident. Look here, Inspector, it's none of my business, but who is carrying out that examination?" "The people at the Central Garage at Westernham. We got them to send out and fetch the car." "Well, without any disrespect to them, I doubt if they will be able to tell you much, unless the defect which you suspect is still very obvious. You see, they are not likely to be experts in this particular make of car, and they might not recognize any unusual adjust- DR. PRIESTLEY LAYS A TRAP 47 ment. If I were you, I'd get on to the Comet people, and get them to send one of their engineers down. If any defect existed, he'd be more likely to find it than anyone else." "I'm much obliged to you for the hint, Mr. Weldon," said the inspector gratefully. "If the garage people haven't found anything by the time we get back, I'll put a call through to the Comet people. I've already asked the Metropolitan Police to call at the addresses given on both Mr. Lessingham's and Mr. Purvis's driv- ing licences, and inform their relatives. That's always the worst part of it. That reminds me of another thing I want to ask you. Why, if Mr. Lessingham lived in London, should he have started on the Rally from Bath?" "I couldn't say off-hand. Competitors were given the choice of nine starting places, of which London was one. The routes by which they had to reach Torquay differed in each case; The controls for those who started from London were Harrogate, Edinburgh, Buxton, and Cambridge. I personally started from Bath because it was the nearest starting place to where I live. Mr. Lessingham may have chosen it because he knew the roads on the Bath route better than any of the others." "I think you told me, Mr. Weldon, that within cer- tain limits competitors could choose their own time of starting. Why did you hit upon eight forty-five p.m.?" "I asked to be allotted as late a starting time as pos- sible. You see, the later one started, the more hours of daylight one got during the following forty hours. 48 DR. PRIESTLEY LAYS A TRAP You may take it that it is dark from six p.m. to six a.m. at this time of year. A car starting at six p.m. would have twenty-four hours of darkness and sixteen light, while one starting at nine p.m. would have twenty-one hours of darkness and nineteen light. I was told that the latest starting time, nine p.m., was already allotted —presumably to Mr. Lessingham—but that I could have eight forty-five p.m." "The same idea must have occurred to Mr. Lessing- ham," remarked the inspector. He said nothing more until they reached Westernham, where, after thanking Bob for his assistance, he left him at the White Hart. Bob found Richard and Harold up, and gorging themselves upon an excellent tea. "Hallo, Skipper!" exclaimed Richard. "We thought you'd bolted from the clutches of the law. They told us that you'd taken out the car and driven off, and we were hoping to see the face of our estimable friend Sergeant Showerby when he heard you'd given him the slip." "Showerby has been superseded as far as we're con- cerned," replied Bob. "I've spent a most interesting afternoon in the company of his superior, Inspector Harraway." "The devil you have!" exclaimed Richard. "And he didn't lock you up at the end of it? Are we still sup- posed to be the bold bad boys who forced the Comet into the ditch? It strikes me that these local sleuths are pretty thick-headed. It's perfectly obvious that those poor fellows went to sleep, and crashed in conse- quence." DR. PRIESTLEY LAYS A TRAP 49 "Don't you run away with the idea that the inspec- tor's a fool," replied Bob. "He's anything but that. And what would you say if I told you that Lessingham and his passenger had nearly six hours' sleep at the Im- perial Hotel in Moorchester last night?" Harold was the first to see the implication. "Six hours' sleep!" he exclaimed. "Then, by Jove, they aren't likely to have gone to sleep at the wheel!" "You're an apt pupil of Dr. Priestley; I can see that," replied Bob. "Then, if they didn't fall asleep, how did the accident happen? That's what the inspec- tor wants to know." "Well, if he does, it's his job to find out," Richard put in. "How long are we to be kept hanging about here? I don't see what it's got to do with us." "We needn't hang about here, as you call it. But we shall have to turn up at the inquest, which will prob- ably be tomorrow, so we may as well stay where we are till then." Richard groaned. "I don't find a small provincial town particularly exhilarating, myself," he said. "It would be different if this was Clayport, and we were at the Unicorn. What on earth does one do here? I say, I've an idea! Let's drive over to Moorchester and spend the evening there." "You always were a restless devil, Richard!" said Bob. "I don't feel in the least like spending the eve- ning in riotous living. I'm going to bed as soon as I decently can after dinner. Meanwhile, a little exercise wouldn't do any of us any harm. What about walking along the road to where the smash happened, and hav- 50 DR. PRIESTLEY LAYS A TRAP ing another look at things?" Harold agreed eagerly, and neither he nor Bob paid any attention to Richard's protests. In the end, all three set out, Bob explaining the situation as he went. "I confess that I don't understand what happened," he said. "If those fellows had as much sleep as it ap- pears, they weren't in the least likely to fall asleep half an hour later. I was pretty well played out this morn- ing, as Harold knows, but after four hours' sleep I could have driven for another couple of hundred miles at least. The inspector's theory is that some defect de- veloped in the car, presumably in the steering." "That's possible, I suppose," replied Richard. "But it's a very unusual thing to happen in a modern car. Look here; what if their lights failed suddenly? All at once, I mean, sidelights and headlights together. That could happen, if the main lead to the battery broke or came adrift." "Yes, I've had something like that happen to me, once," agreed Bob. "But I've two objections to that theory in this case. The first is that the road is dead straight where it happened. You'd think, even if they were suddenly left in the dark, they would have been able to keep the car straight and pull up. The second is that the rear lamp was burning when we came on the scene. I don't quite see what could have happened to extinguish the front lamps and leave the rear one burn- ing." "That sounds reasonable enough," remarked Harold. "It's my turn to make a suggestion. What if the driver lost control trying to pass something on the DR. PRIESTLEY LAYS A TRAP 51 road? Not another car, of course, or we should have seen its tracks. Or a pedestrian, either, for that mat- ter. He or she would hardly have gone on their way and left them in the ditch. But a stray cow or some- thing like that?" "There may be something in that," conceded Bob. "But again I've an objection. They must have been travelling at least sixty miles an hour. Although they put on their brakes, as the tracks show, they hit the ditch hard enough to pitch them both out and smash up the front axle. Nobody in their senses would try to pass a cow on the road going at that pace." "They may not have seen it until they were right on top of it. It may have jumped over the hedge, or come out of the ditch, just as they reached the spot." "Do cows lurk in ditches at night and pounce out upon the unsuspecting wayfarer?" inquired Richard. "I don't know; I'm not an expert upon bovine habits. Anyhow, apart from the classical instance of the cow that jumped over the moon, and that's probably sym- bolical or connected in some way with a solar myth, I know of no instance of a cow behaving like a steeple- chaser." "Oh, shut up, Richard!" exclaimed Harold. "I'll admit that cows may not jump over hedges, but horses can and do." "All right, I'll allow you to transform your cow into a horse," replied Richard. "But what became of Peg- asus after the event? He must have been a bit star- tled by the crash, and I'll wager he pranced about a bit. And if he did, we should have seen the marks of his 52 DR. PRIESTLEY LAYS A TRAP hoofs on the road." "Not if he kept to the grass at the side," remarked Bob. "Well, here we are. We may as well look and see if we can find any traces of Harold's quadruped." But, though they searched very thoroughly, they could find nothing of the sort. And, upon inspection, Harold was bound to confess that his theory of any animal leaping the hedge into the road was improbable. The hedges on either side were six feet high, and wide in proportion. Further, the fields beyond them were under cultivation, and there were no signs of any large animal having passed over them. In the end, they were constrained to return to the White Hart, without having formulated any theory which would account satisfactorily for the mystery. CHAPTER V Bob Weldon's intention of going to bed soon after dinner was frustrated. He had barely finished that meal when a telephone message came for him from In- spector Harraway, asking him if he could come over to the police station. He consented, with as good a grace as he could, and walked down the street to the building with the blue lamp. There was no sign of Sergeant Showerby, and Bob was taken straight into the presence of the inspector, who immediately rose to greet him. "It's very good of you to come over, Mr. Weldon," he said. "I would have come to the White Hart, but I was afraid that we might not find an opportunity for an uninterrupted conversation there." "It might have been a bit difficult," agreed Bob. "I'm at your disposal, if you have anything to ask me." Inspector Harraway smiled. "As my expert adviser, I think you should know that the garage people report that they can find no defect in Mr. Lessingham's car which would account for the accident." "That's very much what I expected," replied Bob. "You're satisfied that they made a thorough examina- tion?" "I think we can assume that they did. They've sent a pretty full report, anyhow. Perhaps you'd like to see 53 54 DR. PRIESTLEY LAYS A TRAP it?" The inspector handed over a couple of sheets of closely typewritten paper, which Bob read carefully. "Not very helpful, is it?" he remarked, as he handed it back. "Plenty of details of the damage caused by the accident, but that's about all. I see that they re- port that the car seems to have had very little wear, and that the speedometer reading is only just over five thousand. You wouldn't expect a serious defect to develop in a modern car after it had run only five thousand miles." "Well, can you suggest any other cause of the acci- dent?" asked the inspector. "I'm not sure," replied Bob thoughtfully. "We did a little detective work on our own this afternoon. I'll tell you about it." He described their visit to the scene of the accident, and the theories that had been put for- ward. "I'm not sure that there may not be something in the stray animal idea," he concluded. "Although we can't find any traces of it." "And I'm inclined to agree with you, Mr. Weldon. Had you been in Mr. Lessingham's place, what would you have done if an animal had suddenly appeared in the road just in front of you?" "It depends on the animal," replied Bob. "If I'd thought it was big enough to wreck the car, I should have done my best to avoid it, and I might have run into the ditch easily in the process. If it was anything smaller I should have gone straight on, rather than risk the lives of my passenger and myself by a sudden swerve." DR. PRIESTLEY LAYS A TRAP 55 Inspector Harraway nodded. "That seems logical," he replied. "I'll bear that theory in mind. By the way, I've had reports from London about Mr. Lessingham and his passenger. Mr. Lessingham had rooms in Cawdor Street. A man-serv- ant was in charge there, who said that he had been with him for several years. He also said that the only rela- tion his master had, so far as he knew, was his cousin, Thomas Purvis." "Who was killed with him," observed Bob. "I won- der who the lady of the telegram can have been?" "I don't think it will be necessary to inquire into that," replied the inspector hastily. "Mr. Purvis's ad- dress turned out to be a private hotel. They knew very little about him there. He had only been there for a week, and they believed that he was home on leave from somewhere in the East, where he held an appointment of some kind. At all events, neither of them appear to have any near relatives. The London police got the name of Mr. Lessingham's solicitor from his man. Far- rant, his name is. He promised to come down here first thing tomorrow morning. The inquest is at eleven, by the way. I shall serve you and your friends with no- tices to attend, but I expect it will be sufficient for you to give your evidence. The coroner probably won't re- quire anything further." "Oh! we'll attend," said Bob. "It won't be the first time we've been to an inquest together. By the way, are you satisfied with the report on the car, or are you going to call in the Comet people?" "I should have been satisfied but for what you said 56 DR. PRIESTLEY LAYS A TRAP this afternoon, Mr. Weldon," replied the inspector. "As it is, I got on to the Comet people and they are sending a man down tomorrow morning. I described the car to them, and they told me it was one they had delivered to Mr. Lessingham early last month." Bob nodded carelessly, and then something seemed to strike him. "Early last month, and his speedometer registers five thousand miles!" he exclaimed. "Lessingham must have been exceptionally fond of driving. His mileage must have been over four thousand before he started on the Rally. That means that he must have driven that distance during February, or more than a thousand miles a week. He wanted to run the car in thoroughly, I suppose." Shortly afterwards Bob took his leave, and went back to the White Hart. It was settled that, as soon as the inquest was over, he should drive home to Clayport, while the others returned to London by train. Next morning, at a few minutes to eleven, they ar- rived at the police station, where a room was used as a coroner's court. It was bare and chilly, with a few forms and a table hastily put in place. It struck them that there was an informal, almost apologetic look about the whole scene. They were shown to a bench near the table, and asked to sit down. The general public was represented by a sprinkling of men and women, who were presumably there because they had nothing better to do. Doctor Mason strolled in, closely followed by a middle-aged man in glasses. And finally, five minutes late, the coroner appeared, accompanied by Inspector DR. PRIESTLEY LAYS A TRAP 57 Harraway. It was not until he had taken his seat and muttered a few inaudible words that Bob realized that the inquest had begun. The absence of a jury, the complete lack of interest evinced by the representatives of the public and the press, seemed to render the proceedings all the more informal. Charles Farrant was the first witness called. The middle-aged man in glasses stood up. He explained that he was the head of the firm of Farrant and Far- rant, solicitors. He had visited the mortuary, and had there been shown two bodies. The first, the smaller of the two, he identified as Aubrey Lessingham, aged thirty-two, a client of his, of independent means. The second was that of Thomas Purvis, Aubrey Lessing- ham's second cousin, aged twenty-nine. He had known Aubrey Lessingham for many years. Although he had not seen Thomas Purvis for some three years, he had no hesitation in identifying him. Thomas Purvis had been in the Malay States during that period, employed by one of the tin mining companies, and, to the best of his belief, had only recently returned to England. The parents of both men were dead, Thomas Purvis had been Lessingham's next of kin, and vice versa. Neither had any near relatives and he could not say at present who was now the next of kin. Mr. Lessingham had never made a will, though on more than one occa- sion he (Mr. Farrant) had urged him to do so. He could not say whether any will of Mr. Purvis' existed. This concluded the solicitor's evidence, and he sat down. The coroner nodded towards Sergeant Showerby, 58 DR. PRIESTLEY UVYS A TRAP who stood up and recited his evidence in a clear voice. Acting upon information received—and here he glanced at the three friends—he had proceeded to the spot on the Moorchester road. And so on, and so forth. Nothing that threw any fresh light upon the matter. Inspector Harraway bent down towards the coroner, and whispered a few words in his ear. "Ah, yes, certainly," he said. "I understand, Ser- geant-ah-Shower by, that you took some photographs of the accident." "Yes, sir," replied the sergeant, importantly. "I have them here, sir. They1 are numbered—" But the coroner cut him short. "A most commendable precaution," he said. "Lay them on the table, they can be admitted as evidence if necessary." He consulted a piece of paper. "Robert Weldon." Bob stood up and gave a brief account of the finding of the wrecked car, and of the steps that had been taken, to which the coroner listened impatiently. "Both you and the deceased were taking part in a contest, I believe?" he inquired. "Was there any ques- tion of a race between you?" "None whatever, sir," replied Bob. "The Rally was not a race in any sense. It was—" Again the coroner interrupted, this time waving his hand with a gesture of irritation. "I do not wish to hear any details," he snapped. "In the absence of any other evidence I must take your word for it that the two cars were not actually racing. It is hard to believe that a race of some kind was not in DR. PRIESTLEY LAYS A TRAP 59 progress. I was awakened several times last night by the noise of cars passing through Moorchestcr at ex- cessive speeds. I am surprised that the police should countenance a contest which causes such inconvenience to the residents of places through which the competitors pass. Inspector Harraway!" Bob sat down. The inspector took his place, and described the result of his investigations. In his opin- ion, the deaths of Mr. Lessingham and Mr. Purvis were due to purely accidental causes. "Of course accidents will happen if people persist in driving at reckless speeds in the dark along the public roads," commented the coroner. "It is to be hoped that no members of the general public have been killed in the course of this contest." Once more he consulted the list of witnesses. "John Meacher!" John Meacher stood up. He explained that he was the proprietor of the Central Garage, Westernham. At Inspector Harraway's request, he had proceeded with a breakdown lorry to the point on the Moorchester Road described by a previous witness. Here he had found a Comet car, with the front portion in the ditch beside the road. Having examined the position in which the car stood, he had taken steps to haul it back on to the road, and had then conveyed it to his own garage. There he had examined the car very carefully, with special attention to the steering gear, and the adjust- ment of the brakes. Considerable damage had been done to the car by the accident itself. But he had been unable to discover any previously existing defect in the 60 DR. PRIESTLEY LAYS A TRAP car which might have caused the accident. The coroner snorted. "Do you consider yourself an expert on the subject of motor-cars?" he asked. "Well, sir, I've been in the trade for twenty years," replied Mr. Meacher, with a suggestion of indignation in his voice. "Very well. At what speed would you estimate this car to have been travelling when the accident hap- pened?" "It is very difficult to say, sir. The brakes had been applied, but the car must have been travelling at least thirty miles an hour when it struck the ditch." "Then it must have been travelling at a considerably greater speed a short time previously. Do you con- sider such a speed to be safe at night?" "With a suitable car and lights, such as the car I examined, and on a straight and open road, I should consider it perfectly safe, sir." "Indeed! In my opinion it is most unsafe. Per- fectly reckless, in fact. You may sit down. Doctor Mason!" Doctor Mason proceeded to give evidence as to the cause of death. When he had arrived upon the scene of the accident, he had found two bodies, identified by a previous witness as those of Mr. Lessingham and Mr. Purvis, lying a few feet in front of the car. Their at- titudes suggested that they had been flung from the car when it came to a sudden stop. Dealing first with the body identified as that of Thomas Purvis, in this case there could be no doubt of DR. PRIESTLEY LAYS A TRAP 61 the cause of death. Mr. Purvis, who appeared to have been sitting beside the driver, had presumably been thrown head first through the windscreen, the glass of which had severed the principal blood-vessels of the neck. A very large quantity of blood was found on the ground beside him, and on the bonnet of the car. No blood had been found within the car itself. Mr. Purvis had probably been stunned by his fall, and had no doubt bled to death within a few minutes of the ac- cident. The case of Mr. Lessingham was not so obvious. He apparently had been driving. The sudden stoppage of the car had flung him violently against the steering column. The column was bent forward, and the steer- ing wheel was damaged. Examination of the body had revealed extensive abdominal injuries, which might or might not have been fatal. But, as was shown by the position of the body when found, the steering column had not arrested its move- ment. Mr. Lessingham had also been flung out, but with less violence than Mr. Purvis. The latter was con- siderably bruised about the head and shoulders, whereas in the case of Mr. Lessingham the bruising was hardly noticeable. He must, however, have struck the ground with sufficient force to have caused consid- erable shock. Examination has revealed that Mr. Les- singham's heart was in a condition which a sudden vio- lent shock might render fatal. The coroner listened to Dr. Mason's evidence with growing signs of impatience. At this point he could contain himself no longer. 62 DR. PRIESTLEY LAYS A TRAP "Are you prepared to state whether death was due to the abdominal injuries or to shock?" he asked. "It is very difficult to decide," replied Dr. Mason. "On the whole, I am inclined to the opinion that the in- juries, though they would probably have proved fatal, would not have been immediately so. It is therefore probable that the immediate cause of death was shock." "Then, since it is a matter of no practical impor- tance I shall record a verdict to that effect." The coro- ner glanced at his notes. "The evidence I have heard leaves no doubt as to the cause of the deaths of these two unfortunate young men. I have no option but to record a verdict of accidental death in both cases. The technical reasons for the accident having taken place do not concern me, as coroner. As I have remarked before, it must be obvious to any sane man that such so-called accidents are bound to occur if motor-cars are allowed the uncontrolled use of the public highways as speed tracks. "I feel it to be my duty to express my opinion very strongly upon this point. I hope that the police will take a lesson from this most unfortunate occurrence, and exercise in future the powers that they possess to put a stop to contests which menace the life and limbs, not only of those foolish enough to take part in them, but of the general public as well. These two young men have fallen victims to the craze for speed which has become such a distressing feature of modern life. It is devoutly to be hoped that their deaths will serve as a warning to others." Then, after a pause to assure himself that the re- DR. PRIESTLEY LAYS A TRAP 63 porters had got his words correctly, the coroner closed the proceedings, and left the court. The witnesses did not follow immediately. Dr. Ma- son was about to make his way out when Mr. Farrant interrupted him. The solicitor seemed in a great state of excitement, and spoke so loud that Bob could not help overhearing much of what he was saying. It seemed to concern the exact time of Lessingham's death. Mr. Farrant took off his glasses and waved them in the air as he spoke. "You understand, Doctor, that it is a most important point," he was saying. "Aubrey Lessingham was a young man of considerable means. He inherited an estate from his father, which was valued for probate at over a hundred thousand pounds. It has depreciated somewhat since then, but the sum involved is still con- siderable." Dr. Mason, who seemed to be in a hurry, tried to get past. "Quite," he replied vaguely. "Quite, but I don't al- together see—" "Perhaps I have not expressed myself with sufficient clarity," said Mr. Farrant, adroitly barring the line of escape for Dr. Mason. "In the course of my evi- dence I remarked that Aubrey Lessingham had not made a will. Now, as you are doubtless aware, Doctor, in cases of intestacy the deceased's estate passes to his next of kin. Aubrey Lessingham's next of kin Was Thomas Purvis, who would then normally have inher- ited the estate." "Well, in any case, he can't do that, since he is dead," 64 DR. PRIESTLEY LAYS A TRAP replied Dr. Mason impatiently. "Excuse me, Mr. Far- rant, but I have a most urgent visit to make." "I shall not detain you more than a few minutes, Doctor," said the solicitor, without budging an inch. "I assure you that this matter is of the greatest im- portance. It will become a leading case if it is neces- sary to refer it to the court. The point is this. Did Thomas Purvis inherit the estate, or did he not? You said in your evidence that Purvis bled to death a few r.iinutes after the accident. In other words, he was alive during those few minutes. Aubrey Lessingham, you say, may have died immediately from shock. In that case, he predeceased Purvis, and Purvis became his heir. The estate therefore devolved upon Purvis, and became his to dispose of. If he also has died intestate, the estate will descend to his next of kin. "On the other hand, if Aubrey Lessingham died of his injuries, he may have outlived Purvis. In that case, failing Purvis, already deceased, the estate passes to Lessingham's next of kin—" At that moment Inspector Harraway came up to Bob. "I wonder if you would mind coming with me to the Central Garage, Mr. Weldon?" he asked. "The man from the Comet Company arrived just before the in- quest began, and I should like to hear his report. And I should be grateful if you would come with me to ex- plain technicalities." "I'll come like a shot," replied Bob. "But I thought that the coroner had ruled that the technical reasons for the accident were of no importance?" DR. PRIESTLEY LAYS A TRAP 65 Inspector Harraway looked over his shoulder hastily. "Between ourselves, Mr. Weldon, the coroner is an ass," he said. "He's got an exaggerated idea of his own importance, and he hates cars like the plague. I believe that it is his proud boast that he has never driven in one. He always carries on in that way when there is an inquest on a road fatality. Anyway, his verdict was sound. He is quite capable of having found that those two poor fellows committed suicide." They walked round to the garage together, where they found the engineer from the Comet Company. He had put on a suit of blue overalls, and was staring at the wrecked car with a puzzled expression on his face. "Well, have you discovered anything?" asked the in- spector. "I have made a very remarkable discovery, but prob- ably not in the sense you mean," replied the engineer. "This is not the car of which Mr. Lessingham took de- livery at our works on February third last, although in outward appearance it resembles it exactly, being one of the same series and colour." "Not Mr. Lessingham's car?" exclaimed the inspec- tor. "I don't quite understand. He was certainly driving it." "Very possibly, but it is not the car of which he took delivery. The chassis number of that car was four three one seven two two, and the engine number six three two naught eight. The chassis number of this car is four three one six seven three, and the engine number six two one four one. I am sure of the num- bers of Mr. Lessingham's car, for I looked them up 66 DR. PRIESTLEY LAYS A TRAP before I left the works this morning. Curiously enough, however, the registration number, ZV nine six nine four, is that of Mr. Lessingham's car. Also the R.A.C. official number, five fourteen, is that allotted to Mr. Lessingham for the Rally." The inspector frowned but said nothing. Bob stared at the official number and the Rally flag, which had not yet been removed. And then he had a sudden inspira- tion. "Have you examined the back axle?" he asked. The engineer turned to him. "No, why?" he replied. "I was a competitor in the Rally," said Bob, address- ing the inspector as well as the engineer. "My official number was five thirteen, and both Mr. Lessingham and myself started from Bath. Every competitor's car was inspected before the start. At the conclusion of the thousand-mile test, certain slow-running, acceleration and braking tests were to take place. In order to en- sure that competitors should use the same gear ratios throughout, the back axles of their cars were painted with a stencilled monogram. My back axle was so marked at Bath, and Mr. Lessingham's must also have been, or he could not have been issued with a route book." The engineer knelt down on the floor of the garage, and crept under the wrecked car. In a minute or two he emerged. "There is no painted mark of any kind on the back axle of this car," he reported. CHAPTER VI When Harold Merefield reached London that after- noon, he was lucky enough to find his employer, Dr. Priestley, in an exceptionally good humour. The cause of this was immediately apparent. Dr. Priestley had just received the proofs of a paper in which he had demonstrated, with his usual ruthless logic, that a certain eminent scientist had been guilty of a grave blunder. The matter involved was so se- verely technical that only very highly trained minds could possibly understand it, but the perusal of the proofs had evidently caused Dr. Priestley the utmost satisfaction. He listened graciously enough while Harold re- counted his adventures, but expressed his disappoint- ment when he learnt that he had been prevented from finishing the course. "I had hoped for the opportunity of examining you before you had slept," he said. "I should have been in- terested in applying certain tests to ascertain the ef- fect of fatigue upon the mental processes. However, it is not your fault. This accident that you speak of could not be foreseen. I inferred that something of the kind had happened when I received a telephone message from Westernham yesterday morning." "You received a telephone message from Western- ham yesterday morning, sir?" Harold exclaimed. 67 68 DR. PRIESTLEY LAYS A TRAP "Yes, from a person who described himself as Police- sergeant Showerby. He wished to know whether you were employed by me. I assured him that you were and asked him if any accident had happened to you." "And what did he say, sir?" Dr. Priestley allowed himself one of his rare smiles. "He said that you were perfectly safe, and added that you were, in fact, under his own eye." Harold laughed. "That wasn't far from the truth, sir. The sergeant had an idea that we were somehow responsible for the accident. He sent us to the local hotel in charge of a constable." "Were there any grounds for supposing that the disaster was not purely accidental?" asked Dr. Priest- ley. "Not then, sir. But, as it turned out later, there was a very queer circumstance connected with the car that was wrecked. But by that time the inquest was over, and a verdict of accidental death returned. The coroner was an irritable and not over-intelligent man, who struck me as having made up his mind before he had heard the evidence. But after his verdict, even Sergeant Showerby displayed no further interest in us." "What was this very queer circumstance to which you refer?" inquired Dr. Priestley. "I should like to tell you the whole story, sir, if you're not too busy to listen," replied Harold. Dr. Priestley nodded encouragingly, and Harold described to him the engineer's discovery, and the absence of the DR. PRIESTLEY LAYS A TRAP C9 R.A.C.'s stencil on the back axle of the Comet. Dr. Priestley listened attentively, in his favourite at- titude, the tips of his fingers together, and his head thrown back so that his eyes were fixed upon the ceil- ing. He said nothing till Harold had come to an end of his story, and even then his comment was not im- mediate. It was only after a considerable pause that he spoke. "And what are your deductions from these facts, my boy?" he asked abruptly. "There's one thing that can safely be deduced, I think, sir," replied Harold cautiously. "The car in which Lessingham and his passenger were killed is not the one in which they started from Bath at the begin- ning of the Rally." Dr. Priestley frowned. "That is an assumption, not a deduction," he said severely. "I will point out some of the fallacies involved in your argument. It does not follow that Lessingham started in the car which had been delivered to him a month previously. Nor is the isolated fact that the stencil was not found on the back axle of any signifi- cance by itself. It might have been erased, accidentally or purposely. Finally, the fact that two men are found dead by a wrecked car is not logical proof that they were driving in it before the wreck. However, presum- ing your assumption to be correct for the moment, could Lessingham have gained any advantage by changing his car en route?" "That's just what's been puzzling me, sir. An ad- vantage might have been gained in this way. If a 70 DR. PRIESTLEY LAYS A TRAP competitor owned two cars, exactly similar in outward appearance, he could have fitted one, which we can call A, with an ordinary back axle, and a normal gear ratio. The other, B, he could have fitted with an axle giving very low ratios, which would be advantageous in the slow-running tests. If he covered the thousand miles in A, and changed to B before the finish, he would gain an advantage. It was to prevent this type of fraud that the cars were stencilled. If Lessingham was try- ing some dodge like this he must have overlooked the fact that his car would be examined for the stencil at Torquay." Dr. Priestley's eyes twinkled. "Given an accomplice, there would be a very simple means of evading that precaution," he said. "The ac- complice would enter car B for the Rally, and would actually start, preferably from a different starting point. He would thus secure the necessary stencil marks. Having started, he would abandon the contest, and drive to some prearranged point, near the finish, where he would await the arrival of A. The transfer would be effected, and the official and registered num- bers interchanged. But this is of purely academic in- terest. Your contention is that Lessingham changed his cars without having taken the precaution I have mentioned." "It certainly looks very like it, sir. I've thought of this. Lessingham lived in London, and, I suppose, ga- raged his car somewhere near his rooms. The route between Droitwich and Moorchester passes close to London. Lessingham would have had plenty of time to DR. PRIESTLEY LAYS A TRAP 71 go to his garage and change the cars. He took ap- proximately six and a half hours to cover a hundred and eighty miles odd, which is an average of less than twenty-eight miles an hour." Dr. Priestley shook his head. "I do not think that the reason for the change of cars, if a change actually took place, is to be found in that direction," he said. "I imagine that steps are being taken to trace the origin of the wrecked car?" "I expect so, sir. The Comet people would know who took delivery of the car bearing that chassis and engine number." "When that is known, the circumstances will prob- ably be explained. Conjecture in the present state of our knowledge would be useless. But even then, I fancy many points of interest will remain." And with that Dr. Priestley abandoned the subject. But it was recalled to his notice sooner than anyone had expected. That very evening he received a visit from Superintendent Hanslet of the Criminal Investi- gation Department, Scotland Yard. The two were old acquaintances. Long ago the superintendent had dis- covered Dr. Priestley's love for an intricate problem, and since that time he had frequently consulted him upon the various criminal cases in which he had been engaged. Dr. Priestley's good humour had persisted, and he greeted his visitor cordially. "To what do I owe the pleasure of this visit?" he asked. "I do not natter myself that you have come here merely to inquire after the state of my health." DR. PRIESTLEY LAYS A TRAP 78 ber had been delivered to one of their agents in Decem- ber last." "Ah, that accounts for it!" exclaimed Harold. "Accounts for what?" inquired the superintendent quickly. "Why, for a point which puzzled Bob Weldon, and which he told us he had mentioned to the inspector. You see, the speedometer showed a total of about five thousand miles. Allowing a thousand for the Rally, he must have covered four thousand miles in a month if this had been the car of which he took delivery on February third. But if the car was actually delivered in December, the mileage becomes more reasonable." Hanslet nodded. "That's a good point," he said. "The agents to whom the car was delivered were the Supremacy Motor Company of Kingston. They gave instructions that the number plates should be painted with the registra- tion number UQ one seven five four. The agent's driver took delivery at the Comet works in North London on December tenth last year. "Harraway then got on to the Supremacy Motor Company. They confirmed the statement of the Comet people. They had used the car as a demonstration car until last month. They had then found a purchaser for it. The car was overhauled, repainted, and put in condition as new. Their customer, Mr. Chalk of By- fleet, drove it away on February seventeenth. "At this stage Harraway got on to us, asking us to get in touch with Mr. Chalk. He should, of course, have communicated with the Surrey police. But, as it 74 DR. PRIESTLEY LAYS A TRAP happened, his mistake saved time. For we had been informed that a grey two seater sports Comet, regis- tered UQ one seven five four, owner's name Chalk, had been stolen on the night of March first." "If it was stolen on the night of March first, Lessing- ham can have had nothing to do with it," said Harold. "His route book, signed by himself, shows that he could have been nowhere near Byfleet that night." "But it wasn't stolen from Byfleet. Mr. Chalk had gone that evening to dine and play bridge with some friends of his. I've got the statement which he made when he reported the loss of the car. 'I live at Byfleet. At about half past six on March first, I drove to the house occupied by my friend Mr. Catesby, near Den- ham, Middlesex. There was no room in Mr. Catesby's garage, so I left my car just inside the drive leading to his house. This must have been at about half past seven. The distance between the two houses is twenty- seven miles by my speedometer. I stayed with Mr. Catesby and his party till shortly before one a.m. I then prepared to drive home, but when I reached the place where I had left the car, I found that it had gone!' Short and to the point, isn't it?" But Harold made no reply. He was rummaging in a drawer from which he produced a road map of south- ern England. This he opened, and spread out on a table. "Just look here a minute, Mr. Hanslet," he said. "Here's Bath and here's Norwich. That was the first stage of the Rally for Lessingham and ourselves. You can see by the map that there are two reasonably di- DR. PRIESTLEY LAYS A TRAP 75 rect routes. The first, and probably the shortest, is by Chippenham, Swindon, Oxford, Bedford, Cambridge, and Newmarket." "Yes, I see that," said Hanslet. "But what's that got to do with this car of Mr. Chalk's?" "Nothing whatever, but wait a minute. That road, though shorter than the one I am going to show you, is winding in places, and not too easy to follow in the dark. We decided upon a longer but faster and more certain road. We kept along the Bath Road towards London till we reached Slough. Then we turned to the left, and came round by Rickmansworth, Watford, and St. Albans till we struck the Great North Road just south of Hatfield. "Now that road took us close to Denham, though not actually through the village. Here is our schedule, which I kept myself. From it you will see that we reached Rickmansworth at eleven fifty-eight p.m. Lessingham was approximately a quarter of an hour behind us. If he followed the same route that we did, he would have passed by Denham somewhere between twelve ten and twelve fifteen a.m." "The dickens he did!" exclaimed Hanslet. "How do you know that?" Harold explained the routes followed by the Rally competitors and the times of the Armstrong and the Comet, as revealed by the route books. Hanslet listened carefully, a puzzled frown upon his face. "Upon my word, that's very queer!" he exclaimed. "You're suggesting, I suppose, that Lessingham saw this car standing inside the drive, as Mr. Chalk de- 76 DR. PRIESTLEY LAYS A TRAP scribes it, and decided to change over, transferring the number plates when he did so?" "And the R.A.C. official number, which was printed on a piece of stout cardboard and attached to the car. That and the flag which was carried by all competitors. It wouldn't take him more than a few minutes to do so." "But why, in heaven's name, why?" asked Hanslet. "And how did he dispose of his own car?" He turned to Dr. Priestley, who had been following the conversa- tion with close attention. "You're good at, solving problems, Professor," he continued. "What is the answer to this one?" "I make it a habit never to attempt to solve a prob- lem until I have the necessary data," replied Dr. Priest- ley quietly. "Necessary data!" exclaimed Hanslet. "That's all very well, but where are we to get it from? Lessingham and his passenger are both dead, so we are told. And , I don't suppose that they took anybody else into their confidence." "Surely, Superintendent, you are jumping to con- clusions," said Dr. Priestley. "You have no evidence that Lessingham passed by Denham that night. He may have taken the alternative route which Harold out- lined." Dr. Priestley rose from his chair and leant over the map. "In which case his nearest point would seem to be Oxford, nearly forty miles away." "I don't know so much about jumping to conclusions, Professor," replied Hanslet indignantly. "The car was found in Lessingham's possession, after all. And it isn't so very far fetched to consider the person found DR. PRIESTLEY LAYS A TRAP 77 in possession of stolen property as the thief." "That person might be a conscious or unconscious receiver of stolen goods," remarked Dr. Priestley mildly. There is reason to believe, from a conversation overheard by one of Harold's friends after the inquest, that Lessingham was a man of considerable means. He was already the possessor of a Comet car. Why should he wish to steal a similar one?" "If you don't mind my saying so, Professor, that's no argument. He may have made a business of steal- ing cars. It has become a regular profession, I can tell you. In that case, the Rally was his opportunity. It strikes me that the flag and the R.A.C. number was a very ingenious way of camouflaging a stolen car. That the cars had been changed would never have been discovered if he hadn't had that smash. You take it from me, he had a confederate hanging round Mr. Catesby's house, who drove Lessingham's car away afterwards. This other man ran no risk, for he could prove it was Lessingham's car." Dr. Priestley shook his head. "Will you explain the system of stencilling cars, Harold?" he asked. Harold did so. "You see, Mr. Hanslet, the car Lessingham was driving would have been examined at Torquay," he concluded. "When the stencils were not found, he would have been called upon to explain why." Hanslet slapped his thigh and roared with laugh- ter. "Why, man alive, you don't suppose he meant to 78 DR. PRIESTLEY LAYS A TRAP turn up at Torquay, do you?" he exclaimed. "Not he. Look here, will your friend Mr. Weldon be called upon to explain why he did not finish?" "Well, no, I suppose not," replied Harold reluc- tantly. "It will be assumed that some breakdown pre- vented him completing the course. Until the actual facts become known, that is." "There you are, you see. Lessingham would have gone on as far as he thought necessary, for appearance' sake. He would then have driven the stolen car to some quiet place he knew of, and faked it so that it could not be recognized. That is one of the tricks of the trade, I may tell you. If any questions had been asked, he would have produced his own car, with a de- fective magneto, or something like that, which would have accounted for his being unable to finish." "In order to prove that to have been his intention, you will first have to find his own car," remarked Dr. Priestley. "I'll see what can be done in that direction," replied Hanslet confidently. "I'm going to make inquiries my- self about this Mr. Lessingham. I shouldn't be sur- prised if this accident led to the exposure of one of the gangs of expert car thieves which are infecting the country. By the way, Mr. Merefield, Harraway said something about a telegram addressed to him. Do you know anything about that?" "Only what Bob Weldon told me," replied Harold. "It was waiting for him at Moorchester, but he never got it. Somebody had wired him to say they could not meet him at Torquay as arranged, and ended the tele- DH. PRIESTLEY LAYS A TRAP 79 gram with the word 'love.'" Hanslet nodded. "Yes, and Harraway thought it must have been a woman in consequence. That was the impression it was intended to create, of course, if anybody but Les- singham saw it. Depend upon it, it was a code, really. As likely as not a message to say that Lessingham's own car had reached its destination, wherever that was. I've asked Harraway to send me up that wire, it may help in running Lessingham's associates to earth." "An undertaking in which I hope you will be success- ful, Superintendent," said Dr. Priestley gravely. Hanslet glanced at him. There had been something in his tone which suggested a lack of sincerity. But his impassive face baffled the superintendent's scrutiny. "I'll have a good shot at it," replied Hanslet, with rather less confidence than before. "Now I'm going to ask you something, Professor. I may want somebody at hand who knows the details of this Rally business. I wonder if you could spare Mr. Merefield for a day or two?" Harold glanced anxiously at his employer. He had already been away for three days, and he was afraid that Dr. Priestley might have some urgent but dreary work for him. Rather to his surprise, the professor's eyes twinkled. "Certainly, Superintendent," he replied. "On condi- tion, that is, that Harold is allowed to report progress to me from time to time." "Then you are interested in all this, Professor?" asked Hanslet in some surprise. "I'm afraid you will 80 DR. PRIESTLEY LAYS A TRAP be disappointed. There's no suggestion of any serious problem arising. It's simply a matter of exposing Les- singham's organization." "Possibly, possibly," replied Dr. Priestley. "I shall be interested in your progress, just the same." Hanslet shrugged his shoulders, and turned to Har- old. "The first thing to do is to visit Lessingham's rooms," he said. "There seems to be a man in charge there, and we'll see what he's got to say for himself. Will you meet me at the corner of Dover Street and Piccadilly at nine sharp tomorrow morning?" Harold agreed to this, and the superintendent after bidding farewell to Dr. Priestley, took his departure. The professor smiled as he left the room, and Harold marvelled anew at his unusual cheerfulness. "It's very good of you to let me go off again like this, sir," he said gratefully. "My compliance with the superintendent's request was not influenced entirely by altruism," replied Dr. Priestley. "I anticipate deriving a certain satisfaction from the result of his investigations. We shall see, we shall see!" CHAPTER VII Both Superintendent Hanslet and Harold were punc- tual at their rendezvous the following morning. They walked to Cawdor Street, a quiet backwater of May- fair, and Hanslet rang the bell of Number 14. It was answered, after a short delay, by a man fault- lessly attired in a black suit. He was the typical gen- tleman's servant, with a quiet deferential manner. His face was flat, and not over intelligent, but it was re- lieved by a pair of sharp, almost cunning eyes. It struck Harold at once that few things would escape his observation. "Mr. Aubrey Lessingham lived here?" inquired Hanslet brusquely. "I'm Superintendent Hanslet of Scotland Yard." The man's face expressed no particular emotion at this announcement. "Yes, sir. Mr. Lessingham's lived here," he replied. "Will you come in?" He stood aside respectfully while the two entered the house, then closed the front door behind them. "Mr. Lessingham's rooms are on the first floor," he continued. "If you will come this way, sir—" "Half a minute," Hanslet interrupted. "Let's have a few particulars first. What's your name, to begin with?" "Orchard, sir. William Orchard. I was an officer's 81 82 DR. PRIESTLEY LAYS A TRAP servant in the war, and—" "Never mind that. How long have you been with Mr. Lessingham?" "Five years, sir; five years next June; ever since Mr. Lessingham took these rooms. I'm a widower, sir, with- out children, and I've got my own quarters on the top floor." "We'll have a look at them later, Orchard. Now then, go ahead and show us Mr. Lessingham's rooms. I may as well tell you at once that I have a warrant en- titling me to search them." Harold, watching Orchard intently, saw an expres- sion on his face which he interpreted as indicating puz- zled surprise. "A search-warrant, sir?" he replied, almost reproach- fully. "I hope that will not be necessary, sir. I am sure that Mr. Farrant would wish me to show you everything that you cared to see." "Mr. Farrant? Who's he?" Hanslet inquired. "Mr. Lessingham's solicitor, sir. He was here yes- terday evening. He told me about the inquest of Mr. Lessingham and Mr. Purvis, and told me to remain here for the present until arrangements had been made for letting the rooms." Hanslet nodded. By this time they had reached the first floor, and Orchard opened a door, bowing them in. They found themselves in a fair sized room, of which the principal features were a thick carpet, and a couple of luxurious armchairs standing before an open grate. Beyond these, there was a table or two, looking rather bare, a few chairs, and a writing desk. The walls were DR. PRIESTLEY LAYS A TRAP 83 covered with a fairly good collection of sporting prints. The superintendent glanced round the room. His eyes rested for a moment on the writing desk, then he sat down in one of the armchairs. "Now, then, Orchard," he said, "when did you last see Mr. Lessingham?" "On Tuesday morning, sir, when I gave him his breakfast. He started soon after that to drive to Bath, where he was to begin the Rally." "He left here as early as that, did he?" remarked Hanslet, with an inquiring glance at Harold. "He would have to report at the Bath control be- tween four and five," the latter explained. "Bath is about a hundred and ten miles from here. He wouldn't want to hurry himself going down." "Was he alone when he left here?" asked the superin- tendent. "Yes, sir. He had arranged to pick up Mr. Purvis at his hotel. They were to drive down together." "You seem to know all about his arrangements, Or- chard. The Rally finished at Torquay on Thursday. When did you expect him back?" "Today, sir. That's when Mr. Lessingham told me to expect him. He said that I could have leave till then, if I wanted to go away. But I had nowhere particular to go, so I just stayed here, sir, and had a thorough turn out of the place." "When did you first hear of Mr. Lessingham's acci- dent?" "When the police came round on Thursday morn- ing, sir. It came as a great shock to me. I couldn't 84 DR. PRIESTLEY LAYS A TRAP understand it, for both Mr. Lessingham and Mr. Pur- vis were expert drivers. It was then that I referred the police to Mr. Farrant, sir." "Yes. Let's get back to Mr. Lessingham's plans. Who did he expect to meet at Torquay?" Harold fancied that Orchard's eyes flickered for a moment. "I am not aware that he expected to meet anybody, sir," he replied quietly. "Aren't you, Orchard?" said Hanslet. "Didn't Mr. Lessingham explain why, although the Rally finished on Thursday, he wouldn't be back here till Saturday?" "He did explain that, sir. I understood him to say that, though the thousand-mile run finished on Thurs- day, there were to be some trials at Torquay, which might take all day Friday, sir." The superintendent glanced at Harold, who nodded. He took a telegram from his pocket, and spread it out before him. "Listen to this, Orchard!" he said. "This is a wire addressed to Mr. Lessingham, at Moorchester, and handed in at South Kensington at six p.m. on Wednes- day. It says, 'Cannot meet you at Torquay as we ar- ranged, love!' Who sent that telegram?" Orchard shook his head. "I cannot say, sir," he replied. "Mr. Lessingham never mentioned to me that he was to meet anybody." "It's not a bit of good trying to bluff me," said the superintendent sternly. "It's pretty obvious that this wire was sent by a lady. Which of Mr. Lessingham's lady friends would be likely to go down and stay with i DR. PRIESTLEY LAYS A TRAP 85 him at Torquay? You say you've been with him for five years, so you ought to know all about his private affairs." Orchard's face assumed a shocked expression. "I am quite sure that Mr. Lessingham had no lady friends of that type, sir," he replied virtuously. "I have never had any reason to suspect anything of the kind." And then a light dawned in his eyes. "If you will allow me to say so, sir, I think you are suffering under a misapprehension," he said. "Perhaps I am," said the superintendent slowly, with his eyes fixed upon Orchard. "Possibly that wire was not sent by a lady, after all." "That is just my opinion, sir," replied Orchard re- spectfully. "Mr. Purvis was lunching here with Mr. Lessingham on Monday, and I overheard a conversa- tion which may explain that telegram, sir." "Oh, you did, did you? Well, I'll trouble you to re- peat it as closely as you can." "Well, sir, the two gentlemen were discussing the Rally. Mr. Lessingham was saying that he would leave Torquay early this morning, and drive straight back here. Mr. Purvis said that would be too late for him. He said he had an appointment in London on Friday morning, and would have to leave Torquay on the previous evening. Mr. Lessingham seemed rather upset at this. It would leave him without a passenger, and he was bound by the rules of the Rally to carry one during the trials on Friday." The superintendent glanced at Harold, who nodded. "That's all right, Mr. Hanslet," he said. 86 DR. PRIESTLEY LAYS A TRAP "The two gentlemen discussed the matter, sir, and at last Mr. Lessingham arranged to get someone in Mr. Purvis's place. 'If you really can't stop, Tom, I'll have to get someone else. I know what I'll do. I'll ring up George Love. He'll come down, like a shot.' I expect this gentleman agreed to take Mr. Purvis's place, but was prevented at the last moment, and sent the tele- gram, sir." Superintendent Hanslet became scarlet in the face from suppressed fury. "And where does this George Love live?" he asked with dangerous calmness. "That I could not say, sir," replied Orchard impas- sively. "I'm not acquainted with him. But I have heard Mr. Lessingham mention his name once or twice previously." Suddenly Hanslet changed the subject. "How did Mr. Lessingham usually spend his day?" he asked abruptly. "Well, sir, he did not get up very early. He rarely breakfasted before eleven o'clock. Then he would sit in here and read his letters and papers. Sometimes he would have a friend, like Mr. Purvis, to lunch here, but more often he went out. After lunch he usually went somewhere or other in his car. He nearly always dined out, and did not usually come back before midnight, usually much later." "Restaurants and night clubs, eh? But look here, Orchard, about going out in the car. He only got it last month, did he?" "This particular one, yes, sir. But he had several DR. PRIESTLEY LAYS A TRAP 87 cars before that. Mr. Lessingham never kept a car for very long, sir. He was always exchanging the one he had for another." "Is that so?" remarked Hanslet meaningly. "Where did he keep his car?" "He rented a lock-up garage in Cawdor Mews, just at the back here, sir. He took the garage at the same time as he took these rooms." "All right; that'll do, Orchard. You can wait up- stairs in your own quarters till we ring for you." As soon as Orchard had departed, the superintendent set to work, silently and methodically. He turned his attention first to the writing desk, going through its contents with a dexterity which aroused Harold's ad- miration. But he found nothing there to interest him, except an address book, which he glanced at rapidly and slipped into his pocket. Having completed his search of the sitting room, Hanslet proceeded to examine the other rooms of which the suite consisted. He went swiftly through the din- ing room, the bedroom, the bathroom and the tiny kitchen. But in none of them did he find anything that cast light upon Lessingham's occupations. Finally, as a measure of precaution, he went through Orchard's quarters, which were situated in an attic at the top of the house. Here, too, he drew a blank; and, after warn- ing Orchard to let him know if any visitors came to the rooms, he and Harold left the house. Hanslet hailed a taxi, and gave the driver the address of Mr. Farrant's office in Bedford Row. During the journey, he studied the address book intently. There 88 DR. PRIESTLEY LAYS A TRAP were quite a number of entries; Lessingham seemed to have had a wide circle of acquaintances. But the pages devoted to the letter L were blank. The name of George Love did not occur. Having arrived at their destination, Hanslet sent in his card, and they were immediately shown into the presence of Mr. Farrant, who stared hard at Harold. "We have met before, I think," he said. "Let me see, now. Were you not at the inquest upon Mr. Lessing- ham at Westernham yesterday?" "That is so, Mr. Farrant," replied Harold. "My name is Merefield. Allow me to introduce Superin- tendent Hanslet." "Since you come in company with Mr. Merefield, I take it that your visit is concerned with the unfortunate event to which I have referred?" said the solicitor, turning to Hanslet. "Exactly, Mr. Farrant," replied the superintendent. "I am hoping that you will be able to give me certain information. I am endeavouring to trace the owner of the car which Mr. Lessingham was driving when the fatal accident occurred." "I cannot tell you that. It seems to me most ex- traordinary, so much so that I am tempted to believe that some mistake must have been made. Inspector Harraway told me, before I left Westernham yester- day, that the car was not the one belonging to Mr. Les- singham, though exactly similar to it." "So I am informed, Mr. Farrant. I have already questioned Mr. Lessingham's man, Orchard, but have learnt nothing from him. It seems to me that if I DR. PRIESTLEY LAYS A TRAP 89 could get in touch with one of his friends, he might be able to help me." "I am afraid that I know none of his friends, except, of course, Mr. Purvis, his cousin, who was killed with him. Although he and his father before him had been my clients for years, we have never moved in the same circle. Mr. Lessingham, like most young men of means, cultivated a different type of society to that of an elderly family solicitor." "I can quite understand that, Mr. Farrant. But perhaps his relatives would be able to put me on the right track." "His relations!" exclaimed Mr. Farrant. "If you can find his present next of kin you will save me an infinity of trouble, Superintendent. I have just drafted an advertisement, which I hope may prove ef- fective. My position is very difficult, since Mr. Les- singham died intestate. In the ordinary course of events Mr. Purvis would have been his heir. But up till now I have been unable to obtain any evidence as to whether he outlived Mr. Lessingham. I fear that it will be an extremely difficult question for the court to decide." "Meanwhile, Mr. Farrant, I understand that Mr. Lessingham changed his cars very frequently. Per- haps he did so immediately before the Rally. It's a point which I am most anxious to clear up." But Mr. Farrant shook his head. "I am afraid that I can give you no assistance what- ever. Mr. Lessingham never consulted me upon such matters." 90 DR. PRIESTLEY LAYS A TRAP "Had Mr. Lessingham any definite occupation?" asked Hanslet innocently. "He had not. Privately, I have always been of the opinion that it was a pity. In my opinion all young men, whatever their position in life, should have some definite object in view. But Mr. Lessingham held that his income was sufficient to justify him in leading a life of idleness." "Didn't he even have some hobby?" The superin- tendent's face wore an air of polite interest. "He had none whatever," replied Mr. Farrant em- phatically. "I happen to know that, for I asked him that very question when I last saw him, as recently as last week. He came here to consult me upon some ques- tion concerned with the lease of his rooms, and when our business was finished, I ventured to suggest that 6ome hobby would be good for him. He told me that his only hobby was driving a car, and that he managed to enjoy life well enough as he was." "Some people are like that," said Hanslet, rather vaguely. "We mustn't waste your time any further, Mr. Farrant." As they left Bedford Row the superintendent chuck- led. "I didn't think we should get much out of Mr. Farrant," he said. "In my experience, getting in- formation out of a solicitor is like trying to get a cork out of a bottle with a pin. I didn't dare tell him that the car had been stolen, and that we suspected his client of having stolen it. He'd have shut up like an oyster." DR. PRIESTLEY LAYS A TRAP 91 "Naturally," replied Harold. "I tell you what it is, Mr. Hanslet, I'm not altogether sure that that chap Orchard was telling us the truth, the whole truth, and nothing but the truth." "Oh, so he struck you that way too, did he? He gave me the impression of being a most accomplished liar. First of all, he said that Lessingham was not expecting to meet anybody at Torquay. That was true enough, since he didn't mean to finish the course. Then I pro- duced the telegram, and he faked up that yarn about George Love. George Love, indeed! I'm willing to bet that no such person ever existed. But it was in- genious, I'm bound to confess. I think, before we go any further afield, we'll call on the Comet people. We may pick up a crumb or two there." They took a taxi to Great Portland Street, and in- terviewed the sales manager of Comet Motors, Limited. "I'm from Scotland Yard," said Hanslet, introduc- ing himself and Harold. "We've already been in touch with you over the telephone. It's this business of the car that Mr. Lessingham was driving when he was killed." "It is the most extraordinary affair altogether," re- plied the manager. "I do not profess to understand it. I knew Mr. Lessingham personally. He came here several times and talked to me before he decided to buy one of our cars." "Could you give us a general idea of his conversa- tion?" "Certainly. He came here first early in the New Year, and said that he thought of entering for the 92 DR. PRIESTLEY LAYS A TRAP Rally, if he could find a suitable car. From what he had heard of our new fifteen h.p. sports model, he thought that it might suit him. We gave him a trial run, and he expressed himself as thoroughly satisfied. To cut a long story short, we eventually persuaded him to buy one, and he took delivery of it on February third. "During February he brought the car back to our works on more than one occasion for minor adjust- ments. He explained that he wanted it tuned specially for the requirements of the Rally; and, naturally, we were anxious to do all we could for him. He came here a few days before the Rally started, and thanked me for what we had done for him. He then seemed very keen, and confident that he would win a prize." "The car that he was driving was similar in every way to the one he bought?" asked Hanslet. "Exactly similar. Unless our customers specify any particular form of body, or other alteration, all the cars of this particular series are built to standard. They are even painted the same colour, which we call Comet grey. They were first exhibited at the Motor Show last November, and I may say that they have proved most successful." "Would you mind telling me, in strict confidence, how many you have sold since then?" "We have actually delivered between a hundred and twenty and a hundred and thirty. In addition to that, we have orders for future deliveries from our agents extending over the next twelve months." "Could you give me an idea of what proportion of DR. PRIESTLEY LAYS A TRAP 93 these have been delivered in the neighbourhood of Lon- don?" "Fully fifty per cent, I should think. I couldn't say more accurately without consulting my figures." Hanslet thanked the manager for his information, and they left the showrooms of Comet Motors, Limited. "The next thing is a spot of lunch," he said. "What about Pagani's? It's close handy." During lunch, the superintendent outlined his plans for the immediate future. "I've had a message sent to Mr. Chalk that we are coming to see him this afternoon," he said. "He doesn't know that his car has been found yet. After we've had a chat with him, we'll have a look at Mr. Catesby's place at Denham. There'll be a car waiting for us at the Yard, and I thought you might drive it. I hate taking a uniformed driver, it's apt to give a wrong impression." "I'll drive it for you, right enough," Harold replied. "I say, doesn't it strike you that Lessingham went to a lot of trouble to steal one car? All that palaver with the Comet people, I mean." "It strikes me that that was only the beginning of his scheme," replied Hanslet. "Entering for the Rally, and buying a car specially for it, put him in a sense above suspicion. I believe he meant to specialize on one particular type of car. As the manager told us, all that series of cars are as alike as so many peas. Les- singham knew that, and saw his opportunity. As soon as he saw one of them about, he or his accomplices found out who it belonged to, and where it was kept, 94 DR. PRIESTLEY LAYS A TRAP or regularly parked. I'll bet he knew exactly where to find Mr. Chalk's car on Tuesday night. "His first effort was to pinch that. But I don't for a moment suppose he meant to stop there. If he hadn't been killed, he'd have carried on in the same way. Cars of this type would have been stolen, one after another. There's just one thing. To steal a car is easy enough. But to dispose of it profitably afterwards is another matter. Now we've got on Lessingham's track, we ought to be able to find out his method of disposal. Orchard knows all about it, I'll warrant. Do you know, I've a pretty shrewd suspicion that Orchard had been round those rooms and destroyed everything compro- mising before we got there? Somebody had, I'll swear. But I'll catch Orchard out, don't you worry." And the anticipation of Orchard's discomfiture gave the superintendent a relish for his meal. CHAPTER VIII Superintendent Hanslet and Harold found Mr. Chalk awaiting them when they reached Byfleet. He was a youngish man, apparently in affluent circum- stances. He dispensed liquid hospitality, and insisted upon their making themselves comfortable before he referred to the object of their visit. It was, in fact, the superintendent who broached the matter. "It's about your car, Mr. Chalk," he said. "You'll be glad to hear that it has been found, though in rather a badly damaged condition, I'm afraid." "Splendid!" exclaimed Mr. Chalk. "The fact that it's found, I mean. As for the damage, I suppose that's a matter for my insurance company. I congrat- ulate you, Superintendent. Where did you find it?" "The credit is not mine, I'm afraid," replied Hanslet. "Mr. Merefield here can tell you more about the find- ing of it than I can. He saw it in the ditch about three miles on the Moorchester side of Westernham, with the driver and his passenger lying dead beside it." "Westernham!" exclaimed Mr. Chalk. "Why, that's where the accident happened to those fellows who were driving in the Rally. I was reading about it in the paper this morning. Lessingham was the name of one of them, wasn't it? And, by Jove, weren't they driving a Comet? What an extraordinary coincidence!" 05 96 DR. PRIESTLEY LAYS A TRAP "Did you know Mr. Lessingham, or his passenger, Mr. Purvis?" asked Hanslet. "Can't say that I did. I never heard their names until I read about the accident. But it's a queer thing. I thought at one time of entering for the Rally my- self. I probably should have, if I had been able to get away in the middle of the week. But I'm in business in the City, and I drive up and down to my office every day but Saturday." "It is curious that you should not have known Mr. Lessingham," said Hanslet, "for the car in which he met with the accident was yours, Mr. Chalk." "Mine!" exclaimed Mr. Chalk incredulously. "How could it have been? The Rally started before my car was stolen. Are you quite sure that there is no mis- take?" "You can decide for yourself, Mr. Chalk. Do you know the detailed particulars of your car?" "I've got them written down in my pocketbook. Here you are. Fifteen h.p. Comet sports, two seater, painted grey. Registration number UQ one seven five four. Maker's numbers, chassis four three one six seven three. Engine six two one four one. Six cylin- ders, bore—" "That's enough to be going on with, Mr. Chalk. The maker's numbers you have just mentioned are those found on this car by the representative of the Comet Company. The registration number plate had been changed, for it bore the number ZV nine six nine four." "Well, I can't make that out at all. It certainly 98 DR. PRIESTLEY LAYS A TRAP do so. I suppose there are twenty or thirty of us all together. On Tuesday I suppose a dozen people were there, beside ourselves and the Catesbys." "Were any of them strangers to you?" "Oh, no, we knew them all. Not intimately, but through meeting them at Catesby's previously. I can't say that I remember all their names at the moment. We stopped playing about midnight, and after yarn- ing a bit we got ready to go home. We were the first to make a move, I remember. I went out to bring the car up to the door, and when I had got to the place where I had left her, I found she wasn't there." "Were there any other cars in the drive then?" "Yes, three or four. They were all nearer the house than mine. I had purposely left my own car near the gate, for easiness in getting away. I couldn't make it out at first. The only thing I could think of was that Catesby's chauffeur or somebody had taken it round to the garage yard. I went up to have a look, but it wasn't there. Then I went back into the house, and told Catesby. "They all thought I was joking at first, but when they saw that I meant it, they all turned out and we started a search. I suppose we spent half an hour looking in every possible and impossible place. But it wasn't a bit of good, and at last it was quite obvious that the car had gone. The only thing we could learn about it was from Catesby's chauffeur. He had been to the pictures or something, and had come back up the drive soon after eleven. He swore that the car was there then. DR. PRIESTLEY LAYS A TRAP 99 "Catesby rang up the local police, and they sent a man round, to whom I gave full particulars. There was no means of getting back here that night, so my wife and I stayed with the Catesbys. And since then I've been going to and from the City by train." "A most irritating occurrence, to lose a car like that, Mr. Chalk. Now, without meaning to be imperti- nent, I should like to ask whether your car was the most valuable of those standing in Mr. Catesby's drive that night?" Mr. Chalk laughed good-humouredly. "No, certainly not," he replied. "There was a Rolls and a big Daimler, I remember. But mine was the easiest to steal. For one thing, she was nearest the gate. And, for another, I had turned her round when I came in, so that she faced towards the road. The others were all facing the house. They would either have to back out, or drive up to the house and turn there." "You say that you are in the habit of going to Mr. Catesby's every Tuesday evening. That was generally known, I suppose?" "Oh, yes, everybody knew it. All my friends round about here, for one thing. They know it's no use dropping in on us that night. And everybody who be- longs to Catesby's bridge circle, for another. In fact, all my friends and acquaintances are sure to know of it." "So that anybody might have known where your car was to be found on Tuesday nights. They might even be aware that you were in the habit of leaving it in the 100 DR. PRIESTLEY LAYS A TRAP drive. Do you habitually leave it unattended in any other place, Mr. Chalk? Where do you keep it in the daytime, when you are in the City, Mr. Chalk?" "In a garage, never in a public parking-place. And when she's here, she's always in my own garage, which is part of the house. But you don't think that some- one had marked my car down as their particular prey, do you?" "I think it very probable," replied Hanslet. "Ex- pert car thieves very rarely steal cars at random. Now, Mr. Chalk, your car is at the Central Garage at Westernham. If you communicate with the police there, and produce the registration book, they will let you have possession of it." Mr. Chalk glanced at the clock. "I think I'll go down there at once," he said. "I'm sure I'm very much obliged to you both. Sure you won't have another drink? Well, then, I won't detain you." As they drove away from the house, the superintend- ent's face expressed a certain satisfaction. "It's all working out very much as I thought it would," he said. "A car left unattended regularly once a week in the same place. Wonderful opportunity for an expert car thief. Chalk couldn't have made things easier for him if he'd tried. Even the way Les- singham got to hear of it presents no difficulties. Chalk and Lessingham have a mutual acquaintance, no doubt, though Chalk isn't aware of the fact." "Yes, that's all very well," replied Harold doubt- fully, "but it seems to me there's a snag in the argu- DR. PRIESTLEY LAYS A TRAP 101 ment. Chalk says that he only took delivery of the Comet on February seventeenth, which was a Wednes- day. The following Tuesday was the twenty-third, and the one after that March first. It was therefore only the car's second visit to the Catesbys' when it was stolen." But this reasoning did not daunt Hanslet in the least. "You don't realize the thoroughness with which men like Lessingham work," he said loftily. "Lessingham decides to specialize in Comets, probably because he knows of a market where he can dispose of them. He therefore keeps his eyes open for likely ones to pick up, and tells his accomplices to do the same. Now, Chalk has owned a car for some time. He mentioned that the Supremacy Motor Company had allowed him some- thing for his old one, you may have noticed. "Well, one of Lessingham's people comes to him and tells him that he knows a man who has just bought a Comet. What's more, he says that he knows where the car will be left every Tuesday evening. I wouldn't mind betting that on February twenty-third Lessing- ham went to have a look at Mr. Catesby's house, and saw the Comet standing in the drive. This was jam for him. He could pass close to Denham on the follow- ing Tuesday night, without putting himself out in the least. And, by Jove, this business gets clearer the further we go. Why did you say he chose to start from Bath at nine o'clock?" "Because the later he started, the more hours of day- light he'd get," replied Harold. - 102 DR. PRIESTLEY LAYS A TRAP "Don't you believe it! He started at nine o'clock for two reasons. First, because that would bring him to Denham at a convenient time for pinching Chalk's car. And second, because he would be the last starter, and there would be no fear of anyone coming up be- hind him while the transfer was taking place. What do you make of that, eh?" "It certainly sounds as if there might be something in it," replied Harold cautiously. They drove into Denham village, where they inquired as to the whereabouts of Mr. Catesby's house. Follow- ing the directions given them, they came to a place just off the road from Denham to Rickmansworth, along which the Armstrong had passed on the first night of the Rally. A gate in a trim wooden paling led into a drive, a couple of hundred yards long, at the further end of which stood a fair-sized modern house. "That's the place, right enough," remarked the su- perintendent. "I don't think we need call on Mr. Catesby. He can't tell us much more than we know already. All Lessingham would have to do would be to change over the number-plates, official number, and flag. He had Purvis with him, and another accomplice, Orchard perhaps, standing by, ready to drive his own car away. How long would the job take the three of them?" "Not more than ten minutes at the most," replied Harold. "The point is, what did they do with Lessingham's own car? Drove it straight to Lessingham's depot, wherever that may be. It's still there, I expect. Les- DR. PRIESTLEY LAYS A TRAP 103 singham meant to drive Chalk's car there on Thurs- day, and change his own number-plates back again." "The problem seems to be to locate this depot, as you call it," remarked Harold. "At present, you've no clue to it at all." "We shall locate it, without any clues," replied Hanslet confidently. "That's where Orchard is going to help us. I've arranged for him to be kept under observation and followed wherever he goes. In the same way, any visitor to the rooms will also be followed. I've also arranged for a record to be made of any tele- phone calls he may put through. He's bound to lead us to the place, sooner or later." After a good look round the vicinity of Mr. Cates- by's house, they drove back to London, and Harold made his way back to Westbourne Terrace. But it was not until after dinner that Dr. Priestley betrayed any interest in his adventures. He listened attentively to Harold's account of his day's work, then relapsed into his favourite position, finger tips touch- ing, eyes fixed upon the ceiling. "This experience should provide you with a very in- structive lesson in the art of deduction," he said acidly. "Consider the facts first, apart from the conjecture with which they have become surrounded. I say, facts, for there are only two occurrences which have been def- initely proved, so far. The first is this. Two men, identified as Lessingham and Purvis, are found dead under circumstances which suggest that they have been killed in a motor accident. The second one is this. The car found on the spot is not the one registered in 104 DR. PRIESTLEY LAYS A TRAP Lessingham's name. I think we may go so far as to say that it is not the car Lessingham was driving when the Rally started. "Inspector Harraway, quite rightly, was primarily concerned with the cause of the accident. He kept an open mind, and his methods of deduction were perfectly sound. In the light of your experience, you and friends leapt to the conclusion that the accident was caused by the driver falling asleep. The inspector's inquiries show that this, to say the least of it, was unlikely. "Other theories to account for the accident were then put forward, none of them, apparently, capable of proof. An inquest, conducted most unscientifically, was held. It was apparently obvious to everybody present that an accident had occurred. The exact man- ner in which the accident took place became of second- ary importance. A verdict was given accordingly, and the inspector pursued no further his inquiries concern- ing the first fact. "The second fact comes into prominence, and is con- sidered without any relation to the first. It turns out that the car had been stolen, and our friend Superin- tendent Hanslet takes the matter in hand. Now, the superintendent's mind suffers from a defect which has very frequently led him astray. Instead of keeping an open mind, he is apt to form a theory upon insufficient evidence. And once this theory is formed all his efforts are devoted to proving it. He is, I gather from what you have told me, convinced that Lessingham stole the car from Mr. Catesby's drive during Tuesday night?" "I think he is quite convinced of it, sir. He believes DR. PRIESTLEY LAYS A TRAP 105 that he completely understands Lessingham's meth- ods." "Just so. Now, looking at the matter logically, he is acting upon pure conjecture. Reverting to the first fact for a moment, there is no real proof that Lessing- ham was driving this car when he was killed. Even if he was, the fact does not prove that he stole it. As I pointed out to the superintendent, he may have been merely a receiver of stolen property. That is a point worth bearing in mind. The essential fact, to my mind, is that at some moment between the time that the car was stolen, and the time when you came on the scene on Thursday morning, one car was substituted for the other." Dr. Priestley paused, and Harold ventured a remark. "You'll admit, sir, that it is a curious coincidence that Lessingham could have been passing close to Mr. Catesby's house at the time the car was stolen?" "My dear boy, you ought to know, by this time, that I never allow coincidence to influence my reasoning. In this case, you cannot prove that Lessingham chose that route. All you can say is that, since you did, he may have done. I am not denying that the substitu- tion may have taken place at that time. I merely sug- gest, with all deference to Superintendent Hanslet, that it may have taken place at any time and place dur- ing the next twenty-four hours or so. "Let us try and estimate the available time more ex- actly. Mr. Catesby's chauffeur saw the car in the drive soon after eleven. It was not there when Mr. Chalk went to look for it 'shortly before one a.m.' It was DR. PRIESTLEY LAYS A TRAP 107 "That may be, sir. But, even if it was the cose, it does not greatly affect the superintendent's problem. The only way in which he can solve it is to find out where Lessingham's car is now, and who drove it there." "Not the only way, perhaps, but still a fairly prom- ising one. How does he propose to proceed?" "He seems pretty sure that Orchard's movements or actions will reveal the hiding place of the car, sir." Dr. Priestley permitted himself one of his rare smiles. "Much of the superintendent's personal charm lies in his incurable optimism," he said. "But try to free your mind from the obsession that Lessingham must have been the actual thief. Suppose, for a moment, that he had no previous knowledge that the substitu- tion was to take place, that he was not, as the superin- tendent insists, a professional car thief. In that case, how could Orchard have any knowledge of the means of disposal of Lessingham's car?" Harold was frankly puzzled, as his expression showed. "I don't quite understand what you're getting at, sir," he confessed. "Possibly not," replied Dr. Priestley, "because you persist in regarding the two primary facts as com- pletely isolated from one another. Superintendent Hanslet is, of course, entitled to his own opinion. But I believe that he has yet to discover the real significance of the case upon which he is engaged." And, without vouchsafing any further explanation,. Dr. Priestley took himself upstairs to bed. DR. PRIESTLEY LAYS A TRAP 109 as his own perquisites." Richard nodded. "I know what you mean, exactly. How far were his answers to the superintendent's questions reliable?" "I don't know. But I had no suspicions that he was not telling the truth until that question of the telegram was raised." "Hanslet's theory is this, I gather," remarked Bob. "Orchard was very possibly the accomplice who took charge of Mr. Lessingham's own car after the theft. The telegram was a code message which really meant 'All well, car in safety.' In that case, Orchard sent the wire himself. That's about it, isn't it?" "I fancy that's it exactly," replied Harold. "Any- l.ow, I'll swear that Orchard was taken aback when the superintendent asked him who Lessingham was expect- ing to meet at Torquay." "Wait a minute," said Bob. "I've been thinking about that telegram since I saw you last. Lessingham can't have been expecting it. It wasn't part of a pre- arranged plan, I mean. If it had been, Lessingham would have asked if there was a telegram for him when he reached the Imperial Hotel." "Oh, I don't know," said Richard. "Remember the circumstances. Personally, I don't remember much about what happened at the Moorchester control. Lessingham must have been as dog-tired as we were. Probably more so, since he and Purvis had driven straight through from Bath, almost without a stop. I can quite understand that he forgot to ask for it when he arrived at the Imperial Hotel. And in the bustle 110 DR. PRIESTLEY LAYS A TRAP of getting off—he was half an hour later than he meant to be, you told us—he might easily have forgotten it again." "No, that won't do, Richard!" exclaimed Bob. "There's no doubt that the superintendent is right on that point. Lessingham can't have had any intention of finishing the course. How was he going to explain the fact that there was no stencil mark on the car he was driving? All that bustle and fuss wasn't genuine. It was merely to impress the people at Moorchester. If he had been expecting a telegram of such impor- tance as that, he would have asked for it all right." "What's your idea, then, Skipper?" asked Richard. "Why, just this. Orchard knew that Lessingham was going to stay at the Imperial Hotel. There's no reasonable doubt about that, since Lessingham had ordered a room there beforehand. The wine was an afterthought on Orchard's part. Perhaps the same for- mula or something like it had been used on a previous occasion. Orchard naturally supposed that Lessingham had received it, and he would assume that he would have destroyed it at once. He was, therefore, taken aback, as Harold puts it, when the superintendent produced it." "Anyhow, he must be a man of pretty quick wit," remarked Richard. "Faking up that yarn of Purvis being unable to stay at Torquay over Friday was good in itself. But the creation of a mythical George Love to account for the last word in the wire is one of the best things I've heard for some time. I should like to make the acquaintance of friend Orchard." DR. PRIESTLEY LAYS A TRAP 111 "He saw that he had made a mistake in sending the telegram," replied Bob. "His natural instinct was to explain it away. I'll admit that he hit on a very in- genious explanation, but I think he would probably have done better to deny all knowledge of it. The only result of his yarn is to convince the superintendent that he's a liar." "There's just one thing about all this," said Rich- ard. "Nobody seems any nearer knowing why Lessing- ham ran into the ditch." "And apparently nobody cares, now that a verdict of accidental death has been given," replied Harold. Lunch over, Harold executed some commissions for Dr. Priestley, and returned home. Nothing further was said about the matter until the evening, when Superintendent Hanslet paid a visit to Westbourne Terrace. He plunged at once into the subject. "I expect that Mr. Merefield has told you about our adventures on Saturday, Professor?" he asked. Dr. Priestley nodded. "He gave me a very full account," he replied, noncommittally. "Then you'll have heard what Orchard told us about the telegram. It was quite obvious that he was lying, as Mr. Merefield will tell you. I didn't let him see that I suspected this at the time, but I've been making in- quiries. The first thing I did was to call round at the hotel at which Mr. Purvis had been staying. He had told the people there that he was going on the Rally. A car, which answers to the description of Lessing- ham's, called for him on Tuesday at about noon. And 112 DR. PRIESTLEY LAVS A TRAP he had said that he would be away for a couple of nights, but hoped to be back some time on Thursday." Harold uttered an exclamation of surprise. "But surely, that confirms Orchard's account of the conversation between him and Lessingham!" he ex- claimed. "At first sight it does," replied Hanslet. "But, if you remember that Lessingham never intended to com- plete the course, Purvis's instructions are explained. He and Lessingham intended to return on Thursday, all along. Orchard only invented the conversation to fit in with the supposition that Lessingham meant to go through the whole Rally. "The next thing I did was to make inquiries at South Kensington about the wire. I got hold of the original form upon which it was written, but nobody in the Post Office can remember who handed it in. I'd like you to look at the form, if you don't mind, Professor." He handed it to Dr. Priestley, who scanned it through his spectacles. "This was written with a hard pencil by somebody who seems to have been in a considerable hurry," he said. "The wording is legible enough, but the ends of each word are slurred. There is, however, a full stop inserted between the two last words of the message, 'arranged' and 'love.'" "Which wasn't telegraphed, of course. But that's a detail, Professor. What do you make of the hand- writing itself?" "It is undoubtedly an educated hand," replied Dr. Priestley. "I am not an expert in handwriting, but DR. PRIESTLEY LAYS A TRAP 113 this appears to display certain feminine characteris- tics." "Exactly!" exclaimed the superintendent trium- phantly. "What becomes of this mysterious George Love now?" "For that matter, Superintendent, what becomes of your theory that Orchard sent the telegram himself?" replied Dr. Priestley mildly. "It seems to me to be quite possible that George Love had a wife or sister who sent the telegram for him." "That argument works both ways, Professor. Or- chard may not have cared to risk sending the telegram himself, and got someone else to do it." "In either case, if the telegram was written out by a woman, a new factor is introduced into the problem." "Not a very important factor. I expect Lessingham had women among his accomplices. It doesn't affect the main issue. Orchard is lying very low. He hasn't attempted to use the telephone, and he's hardly left Cawdor Street at all, and then only to do some shop- ping. What's even more curious, he's had no visitors. I haven't found anybody yet who can tell me anything of his comings and goings after Lessingham left. "So much for the telegram. It's not of any great importance, after all, and I'm inclined to put it aside for the present. I had a message from Mr. Farrant this morning. He seems to think the Yard can help him with his troubles, but I don't quite see how. He seems to be boxed up over the question as to who Les- singham's heir is." "Harold told me that he intended to advertise," re- [114 DR. PRIESTLEY LAYS A TRAP marked Dr. Priestley. "He has done so, but so far without receiving any replies. But he has also sent a cable to Purvis's em- 1 ployers out East, asking that a search for a will of his be made. To this he has had a reply that such a will exists, and that particulars are being sent by mail." "Ah! here we have at last a problem of real inter- est!" exclaimed Dr. Priestley. "We may assume, I think, that Purvis bequeathed everything of which he might die possessed to some person, or that he made that person his residuary legatee. Now, of what did he, in fact, die possessed? That is the question to be decided." "Mr. Farrant had that in his mind at the time of the inquest, sir," remarked Harold. "Exactly. He foresaw the position which might arise, and has now apparently arisen. If Purvis died before Lessingham, he never inherited from him, and his estate consists only of what he possessed at the time of the accident. But if Lessingham died first, Purvis succeeded to his estate, though he may have only sur- vived him for a few seconds. In that case, his estate includes Lessingham's." "Well, Professor, that's a matter for Lessingham's present next of kin, whoever he or she may turn out to be, and Purvis's executors to wrangle over. It doesn't concern us in any way. I'm afraid we can't help Mr. Farrant's troubles. I only told you about his message because I know you like to hear everything, whether it's really got anything to do with the case or not. And now I'll come to the real point of my call. DR. PRIESTLEY LAYS A TRAP 115 Can you spare me Mr. Merefield again for an hour or two tomorrow morning?" "Certainly, if he can be useful to you. May I ask what line your investigations are about to take?" "Mr. Chalk was on the telephone this morning. He told me that he went down to Westernham on Saturday afternoon to see his car. He told me that he had no doubt at all that it was his. He looked in the tool-box, in the presence of Sergeant Showerby, by the way. There he found a peculiarly shaped shifting spanner which he is prepared to swear to. It isn't part of the standard equipment of the car; he put it in the box himself. He also pointed out to the sergeant that a brass plate, which he says bore the words 'Supplied by the Supremacy Motor Co., Kingston,' had been un- screwed from the dash." "Doubtless to render the identification of the car more difficult," Dr. Priestley observed. "Of course. The first thing a car thief would think of. Mr. Chalk went on to tell me that he had made arrangements with his insurance company that the car should be taken to the Comet works for repair. The Comet people have sent a lorry down for it today, and it will be in their works by now. I should like to have a look at it myself, and I have arranged with Mr. Chalk for him to meet me there at ten o'clock tomorrow morn- ing. Since Mr. Merefield saw the car directly after the smash, I thought it might be a good thing if he came with me." Dr. Priestley made no comment for some minutes after Superintendent Hanslet had gone. From his DR. PRIESTLEY LAYS A TRAP 117 So Harold met the superintendent next morning with the notes which Dr. Priestley had dictated in his pocket. Mr. Chalk had not arrived yet, and he put the question about the photographs at once. "No, I haven't got them," replied Hanslet. "The accident has nothing to do with me. But there's noth- ing to prevent the professor having a look at them if he wants to. I'm only too glad that he's taking an interest in the case. I can't quite understand why; it's straightforward enough. If you'll remind me when we leave here, I'll ring up Sergeant Showerby. We may as well go and have a look at the car while we're wait- ing for Mr. Chalk." They entered the works, where they were greeted by the engineer who had examined it at Westernham. "Nothing has been touched," he said. "It's exactly as I first saw it. We shan't get to work until we've settled with the insurance company how much it will be necessary to do." As soon as he saw the car, Harold realized that noth- ing had indeed been touched. Not even the spots of blood upon the bonnet had been removed. With Dr. Priestley's instructions in mind, he examined it very carefully. This done, and Mr. Chalk having not yet put in an appearance, he approached the engineer. "You haven't found anything to account for the accident, I suppose?" he asked casually. "No, I haven't," replied the engineer. "I can't make it out at all. This man, Lessingham, must have swerved suddenly for some reason, and lost control. I can't explain it any other way. There's nothing the 118 DR. PRIESTLEY LAYS A TRAP matter with the car, except, of course, the damage caused by the crash. Apart from that, she's in as good condition as when we delivered her." "Nothing about her has been altered? No gadgets fitted, or anything of that kind?" "Nothing whatever. I examined her pretty care- fully at Westernham, and I've been over her again this morning. She has been exceptionally carefully looked after. The oil in the sump has been regularly changed, chassis lubrication attended to, and so forth. The only thing that has been done is that a new pin has been fitted at the front end of the steering rod. I suppose that the original one had worn a trifle, though it's most unusual." "How can you tell that a new pin has been fitted?" asked Harold. The engineer smiled. "You can see for yourself if you look closely," he replied. "Do you see that the pin is not quite the same colour as the rest of the chassis? That's one of our pins, and it fits perfectly. But what has happened is this. Somebody, probably the agents from whom Mr. Chalk bought the car, thinking the original pin had worn a bit, ordered a new one from our spare parts' department. Now, we send out spare parts unpainted. Whoever fitted the pin painted the head as near as they could get to our Comet grey, to match the rest of the car, but they didn't exactly hit off the right shade. You can see the difference, now I've pointed it out to you? But, of course, a new pin having been fitted wouldn't impair the efficiency of the car in any way." DR. PRIESTLEY LAYS A TRAP 119 At this moment Mr. Chalk came in, apologizing for being late. He spent some time explaining how he could identify the car as his own. The only things missing from it were a couple of rugs. And then Har- old got a chance of a word apart with him. "Do you happen to know what your speedometer was registering when the car was stolen?" he asked. "Well, not exactly," replied Mr. Chalk. "But, as it happens, I can tell you this: I know I was getting pretty close to the five thousand mark, and I'meant to make a note in my diary when I reached it. When I came back from the City on Tuesday afternoon I looked at the mileage and saw that I had only four miles to go. The speedometer showed 4996." "How far do you make it from your house to Mr. Catesby's?" asked Harold. "Oh, I've measured that often enough on other cars I've had. There are two or three ways of going, but by the road I took last Tuesday it is twenty-six miles exactly. I must have checked it half a dozen times." Their conversation was interrupted by Superintend- ent Hanslet. "Much obliged to you, Mr.' Chalk," he said. "I'm glad to have your personal identification of the car. I hope it won't be long before you're on the road again. Next time you go to see Mr. Catesby, I wouldn't leave the car in the drive, if I were you. We may as well make a move, Mr. Merefield. There's nothing more we can do here!" Harold followed the superintendent out of the works. "What's the next move?" he asked. 120 DR. PRIESTLEY LAYS A TRAP "Get back to our respective jobs," replied Hanslet. "Criminal investigation doesn't always mean dashing about the place. More often than not it pays to sit down and wait, like a cat over a mousehole. It's the turn of the other side to play now. Orchard is bound to make a move, sooner or later. And there's Lessing- ham's own car. That won't stay in hiding indefinitely. It can't have been disposed of already. As soon as it appears on the road, whatever disguise it's in, we'll have it." Harold smiled. He remembered a certain car that had once eluded Hanslet's search until Dr. Priestley provided him with a clue as to its whereabouts. "You'll be along to see the professor in a day or two, I expect," he remarked. The superintendent shrugged his shoulders. "Possibly," he replied. "I don't see that he can be much use, though. But as soon as I've found out where Lessingham's car has been hidden, I'll look in. I ex- pect he'll like to hear the end of the story. You might tell him that I'm much obliged to him for letting me take you off like this. I'll have those photographs sent to him, by the way." They parted, and Harold made his way back to Westbourne Terrace, wondering whether even Dr. Priestley could deduce anything from the information which he had collected. That something was at the back of the professor's mind he knew, but as to what it was, he could not even hazard a guess. CHAPTER X Dk. Priestley seemed anxiously eager to hear the re- sult of Harold's inquiries. He settled himself at the table in his study, and provided himself with pencil and paper. "We will take the question of the speedometer, or, to be more accurate, the mileage recorder, first," he said. "Had Mr. Chalk any idea of the reading when the car was stolen?" "When he got home from the City on Tuesday the reading was four thousand nine hundred and ninety- six miles, sir. He says it is twenty-six miles from there to Mr. Catesby's house at Denham." Dr. Priestley made a note of these figures. "The mileage when the car was stolen was therefore five thou- sand and twenty-two," he said. "Now, were you able to observe the reading now showing on the instru- ment?" "It was fifty-one hundred and forty-two miles, sir. And it must have been that at the time of the crash, for it has been impossible to move the car on its own wheels since. The speedometer appeared to be in working order, as far as I could tell." Dr. Priestley made a second note, and then referred to the map which was spread out on his table. "How far from Moorchester did the accident take place?" he asked. 121 122 DR. PRIESTLEY LAYS A TRAP "Three miles short of Westernham, sir. Western- ham is eighteen miles from Moorchester." "Assuming, then, that the car passed through Moor- chester, and that the mileage recorder was in order, the reading when iti left Moorchester should have been fifty-one twenty-seven. That seems to me highly sig- nificant." "The car certainly passed through Moorchester, sir. Lessingham reported to the control, and he and Purvis signed the route book. Besides, the R.A.C. man saw them get into the car and drive off." "Did the R.A.C. man examine the maker's numbers on the car?" asked Dr. Priestley acidly. "If he did not, there is no proof that the car he saw was the one that you found by the roadside. However, for the moment I will assume that it was the same. How far did you calculate it was from Windsor to Moorches- ter?" Harold referred to his schedule. "Eighty-seven miles, sir, by the route we planned to take," he replied. For a minute or two Dr. Priestley made no reply. He was engaged with a rotary measurer on the map. "I make the distance from Denham to Moorchester ninety-one miles," he said. "That agrees very well with the figure which you have just given me. Now, it is a curious fact that the mileage reading of the car when stolen was five thousand and twenty-two, and when it left Moorchester fifty-one hundred and twenty- seven. The difference is ninety-five miles. Does that suggest anything to you?" 124 DR. PRIESTLEY LAYS A TRAP stitution then took place, and Lessingham drove the car on to Moorchester, the mileage would have risen to fifty-one hundred and twenty-seven, or thereabouts. The same thing would have happened if the substitu- tion had taken place at Moorchester itself." Harold considered this for a moment or two. "In any case, it comes to this, sir," he said. "The substitution must have taken place on Wednesday, not Tuesday night. And in that case I cannot see what Lessingham's game was. Why should he hide the stolen car all through Wednesday, with the risk that it would be found during that time?" "Why, indeed?" replied Dr. Priestley drily. "But remember, there is always the possibility that Lessing- ham may have put the speedometer out of action, or tampered with it in some way. For instance, he may have stolen the car on the first night, and immediately disconnected the speedometer. He may then have driven the car round the Rally course, and connected the speedometer again when he passed through the neighbourhood of Denham on the second night. But why should he do so? He could not have anticipated the accident, and the inquiries that would ensue. No, the balance of probability seems to me that the substi- tution took place on the second night." "Well, sir, then this must be the explanation. Les- singham intended to steal Mr. Chalk's car. He could only do so on Tuesday night, since on Wednesday night it would be safely locked up in its own garage. He did so, hid it in some place he had already prepared, and picked it up on Wednesday night. But I can't under- DR. PRIESTLEY LAYS A TRAP 125 stand why he did not change over at once, unless on Tuesday he had no one to take charge of his own car." "Then why not leave his own car in this hiding place, thereby lessening the risk of discovery of the stolen car? Your reasoning, my boy, is consistently based upon the preconceived theory that Lessingham stole the car. There is not an atom of proof that he did so. There is no evidence that he was within forty miles of Denham on the first night." "But even if he didn't steal the car himself, sir, he must have known all about the theft. In fact, it is pretty certain that he must have arranged it. Other- wise, why did he consent to the substitution?" "That is a question that we cannot yet answer," re- plied Dr. Priestley, with sudden gravity. "When we can, we shall be considerably nearer a solution of the problem than we are now. Conjecture upon that point is useless at this stage. But I think that the matter of the mileage readings is of the first importance. I should like you to go back to the Comet Motor Com- pany's works, and renew your acquaintance with the engineer to whom you spoke this morning. I should like his opinion upon the possibility of the speedometer having been disconnected or tampered with." Harold went off on his errand, and it was not until that evening that he returned. After dinner, Dr. Priestley returned to the subject. "While you were out this afternoon, I received a most interesting collection of photographs," he said. "They were sent to me by Sergeant Showerby, and he must have considered the matter urgent, for he dis- 126 DR. PRIESTLEY LAYS A TRAP patched them by passenger train to save time." "I expect that he wanted to bring himself to the notice of the Yard, sir," replied Harold. "Superin- tendent Hanslet's name would mean a lot to him." "Very possibly. However, we will defer discussion of the photographs until later. Let me hear the result of your investigations at the Comet Motor Company's works." "I found the engineer, sir, and told him that there was reason to suspect that the speedometer might have been tampered with. He and I examined the car very carefully together. Oddly enough, in spite of the dam- age to the front of the car, the speedometer and its connections are uninjured. "We came to the conclusion that the speedometer had never been disconnected. It would have been im- possible to do so without leaving marks on the paint. You remember, sir, that the car had been overhauled and repainted just before Mr. Chalk took delivery of it, just a fortnight before the accident. And the paint is still unbroken over the connections. As to tampering with the instrument itself, sir, the engineer assured me that it couldn't be done without leaving still more ob- vious traces." "That seems satisfactory. Did you discuss any other method by which the mileage record could be falsified?" "There was only one other way that was possible, sir, and that not in this case. Some mileage recorders work in the reverse direction when the car is run back- wards. Their readings can therefore be set back if DR. PRIESTLEY LAYS A TRAP 127 the front wheel is jacked up and then revolved counter- clockwise. But the particular speedometer fitted to the Comet has a ratchet device, which prevents the mileage recorder functioning when the car runs backwards." "Then all possibilities of the record having been falsified are eliminated," remarked Dr. Priestley. "We may now say with some certainty that the substitution took place during the night of the second and third* somewhere between Denham and Moorchester, or at either place itself. Now, let us consider these photo- graphs. Will you describe to me again how the bodies of Lessingham and his passenger were lying when you first saw them?" "They were lying a short distance apart, sir, on the further side of the ditch. Purvis was stretched out on his face, Lessingham was rather more on his left side, with his legs drawn up. Both bodies were directly in front of the radiator of the car, and a few feet from it." "Suggesting at once that they had been thrown from it, in a forward direction, by the impact?" "Yes, sir. Purvis had apparently been shot head- first through the windscreen. Lessingham must have cleared it, for he was not cut about at all." Dr. Priestley had followed Harold's description with the photographs. "Yes, "that appears to have been the case," he re- plied. "We can understand it in the case of Purvis, I think. He was presumably sitting beside the driver, and there was nothing between him and the windscreen. "The case of Lessingham is slightly different. He was driving, and had the wheel and steering column in 128 DR. PRIESTLEY LAYS A TRAP front of him. These are damaged, you told me. Did you observe the damage more closely this morning?" "Yes, sir. The column itself is bent forward at least six inches. The rim of the wheel is flattened, and one spoke of it is broken." "The medical evidence at the inquest was to the effect that Lessingham was suffering from severe ab- dominal injuries. The natural inference is that he was flung against the steering column by the force of the impact. It seems to me a curious fact that this did not arrest his motion. In spite of the retarding action which it must have had, Lessingham's body continued its progress, and reached a spot approximately the same distance from the seat as that reached by Purvis, who was not retarded." "But perhaps a fraction of a second later," sug- gested Harold. "That explains why he was not cut about. Purvis had already broken most of the glass out of the screen." "A good point, my boy," said Dr. Priestley approv- ingly. "But still, I should have expected to find Les- singham's body within the car rather than outside it. But that is a matter which concerns the cause of the accident. These photographs taken by Sergeant Showerby show very clearly the tracks of the car before it left the road. There are, I notice, two sets of tracks only, those of the car driven by Lessingham, and those of the Armstrong. Since no other tracks are visible, I gather that no great volume of traffic uses the road?" "Not at that time in the morning, sir. So far as I can remember, we saw nothing on the road after we left DR. PRIESTLEY LAYS A TRAP 129 Moorchester until we came upon the Comet." Dr. Priestley took out the map and studied it. "There are two roads westward from Moorchester, I see," he said. "The one followed by you and Lessing- ham, which passes through Westernham, and a second, running roughly parallel to it, but nearer the coast. By the map, the coast road appears to be the shorter. What made you select the inland road?" "Because, though it may be a trifle longer, it is a good deal faster, sir. The coast road is narrow andi very hilly, and, since it is not much used, is not in very good repair." Dr. Priestley examined the contours on the map. "Yes, it certainly appears to be hilly," he replied. "I see that it follows roughly the crest of a ridge, to the southward of which is the sea. The road you took, on the other hand, lies in the valley. At intervals minor roads connect the two. The lower road should be vis- ible from the crest of the ridge for the greater part of its length. In fact, from the upper road the view would be over the sea to the southward, and over the valley to the northward." "I can't say, sir, I've never been along it. Bob Weldon could tell us; he knows that part of the world." Dr. Priestley made no reply, but continued staring at the map. Harold wondered why he had strayed away from the subject, but was too wise to ask ques- tions. At last his employer put the map away, and turned once more to the photographs, which he studied again intently. "It appears that Sergeant Showerby took photo- 130 DR. PRIESTLEY LAYS A TRAP graphs only of the tracks behind the wrecked car," he said. "Were there any tracks visible in front of it, that is to say, on the Westernham side?" "Not of the Comet, of course, sir. But by the time the light was good enough to take the photographs there were plenty. There were our own tracks, going to and coming from Westernham to fetch the sergeant, the tracks of Dr. Mason's car, coming out, turning, and going back, and the tracks of the constable's bi- cycle." "So that if any tracks had existed, they would by then have been indistinguishable?" "I should say completely, sir. I don't think that anybody looked for them in that direction. As you can see from the photographs, sir, nothing had passed the scene of the accident till we came along." "Passed, no!" replied Dr. Priestley irritably. "However, let us return to the tracks of the wrecked car. You have told me that several explanations have been suggested to account for the curious wobbling visible before the car left the road. Which, in your opinion, is most likely?" "Well, sir, I'm inclined to hold to my own theory, that Lessingham lost control of the car while trying to avoid something that suddenly appeared on the road in front of him. That would account for the wob- bling." "What do you mean exactly by his losing control of the car?" "Swerving suddenly, sir, and then endeavouring to correct the swerve. If he was travelling at a high DR. PRIESTLEY LAYS A TRAP 131 speed, he may not have been able to apply the correc- tion quick enough. When the wheel struck the grass edge, it may have wrenched the steering wheel out of his hands. And that would mean disaster." "The tracks certainly suggest loss of control," agreed Dr. Priestley. "But could this control not be lost through a mechanical failure of the mechanism, rather than through a physical failure on the part of the driver?" "It could, sir. That was Inspector Harraway's idea. But if such a mechanical failure had occurred, the reason of it would be apparent. And the engineer at the Comet works declares that the car must have been in perfect order when the accident happened." Dr. Priestley shook his head. "That is going too far," he said. "All that he can state with certainty is that the car, allowing for the damage caused by the accident, was in perfect order when he examined it. And that is an entirely dif- ferent matter. It is also safe to assume, I think, that the car was in perfect order when it was stolen. But we have no evidence that it was so during the interven- ing period. The important point seems to be, was it in perfect order at the time of the substitution?" "Surely, sir, Lessingham would have assured himself of that before he took it over?" "Lessingham, Lessingham!" exclaimed Dr. Priestley petulantly. "I believe that you and the superintendent have Lessingham on the brain. How do you know that that unfortunate individual knew anything about it?" "Well, after all, sir, he was killed while he was driv- 132 DR. PRIESTLEY LAYS A TRAP ing the car!" expostulated Harold. "Was he? How do you know? Did anyone see him driving a car known to be Mr. Chalk's? Even suppos- ing that he was? Is that any evidence that he stole it? Let me put a parallel case to you. A certain half- crown is marked in such a way that the mark is invisible to the unaided eye. This half-crown is stolen from its owner. Thirty hours later it is found in your posses- sion. Is that proof positive that you stole it?" "No, sir, it isn't," Harold admitted. "But surely—" Dr. Priestley brushed his protest aside. "Why is it not proof against you?" he persisted. "Because I might have acquired it perfectly inno- cently, sir. For instance, the thief might have given it to me, with other coins, in exchange for a pound note. All half-crowns are similar, and I could not be ex- pected to see a mark which was invisible to the naked eye." "You would, in fact, be an unwitting, and there- fore innocent, receiver of stolen goods. Why should not Lessingham have been in exactly the same position? Why should not the cars have been substituted without his knowledge?" Harold's reply was interrupted by the entrance of Mary, the parlourmaid, with the message that Super- intendent Hanslet had called, and would like to see Dr. Priestley. The latter hesitated, and a slight frown crossed his face. "Very well, let him come in," he said curtly. Hanslet entered the room, a triumphant smile upon his face. It was clear that some important piece of DR. PRIESTLEY LAYS A TRAP 133 news was on his lips. But Dr. Priestley pointed to a chair. "Sit down, Superintendent," he said. "Harold and I were just expounding some possible theories to ac- count for the accident to the car that Lessingham is believed to have been driving when he was killed. Since you have arrived so opportunely, it may interest you to hear them. What was it that you were about to say, Harold?" But the superintendent, exasperated by Dr. Priest- ley's manner, could contain himself no longer. "The accident?" he exclaimed. "Why that's ancient history, Professor. All that's over and done with long ago. I dropped in to tell you something much more important than that. Lessingham's car has been found!" DR. PRIESTLEY LAYS A TRAP 135 rect. I shall have to work it out in my own mind. But it doesn't affect the case at all. It merely means that Lessingham or his accomplice stole the car on Tuesday night, but that the change-over wasn't made till Wednesday night. It's really only a matter of detail." "It may prove to be considerably more than that," replied Dr. Priestley patiently. "Now, just before you came in, Harold and I were discussing a rather inter- esting possibility. It was that Lessingham had no knowledge whatever of the theft, but was an unwitting, and therefore innocent, receiver of stolen goods." Hanslet stared at Dr. Priestley as though he had taken leave of his senses. "You mean that somebody exchanged one car for the other without his knowledge?" he said incredulously. "But, if you'll excuse my saying so, Professor, that's absolutely ridiculous!" "Rather a strong expression, Superintendent," said Dr. Priestley equably. "Would you mind telling me why you consider it ridiculous?" "Because there could be no possible point in anybody doing such a thing," replied Hanslet promptly. "You'll admit that the only person who could have substituted one car for another was the man who stole Mr. Chalk's? Very well. What had he to gain? Hav- ing stolen a car, his problem was to dispose of it. He would want to get rid of it, to pass it on to someone else, as soon as possible, it's true. But what advantage was it to him to exchange it for an exactly similar car? He had, if you like, disposed of one stolen car, but in 136 DR. PRIESTLEY LAYS A TRAP doing so he had burdened himself with another. For, in exchanging the cars, he had clearly stolen Lessing- ham's." "It is the motive, then, that you consider ridiculous, and not the substitution itself," said Dr. Priestley. "We will consider the motive later. For the moment we will consider the act of substitution. You will not deny that this, in fact, took place?" "Of course I won't; it's a perfectly obvious fact. But I don't see how it could have been done without Lessingham's knowledge." "On my part, I consider that it would be a compara- tively easy matter. Your investigations have shown that the various cars of tins particular model are ex- actly alike. They are built to standard, are fitted with identical equipments, and are even painted the same distinctive colour. "Before these two cars, Mr. Chalk's and Lessing- ham's, left the maker's hands they were indistinguisha- ble except for the numbers engraved on the engine and the chassis, and these were not readily discernible by the ordinary observer. Subsequently, other dissimi- larities began to appear. The cars were allotted dif- ferent registration numbers, and these were painted on plates attached to the respective cars. Mr. Chalk's car had a brass plate attached to the dash by the Suprem- acy Motor Company. At the time when Lessing- ham's car started for the Rally, it bore a flag and an official number. All these subsequent distinctive marks were easily recognizable. How were the flag and the official number attached to the competing cars, Har- DR. PRIESTLEY LAYS A TRAP 137 old?" "In our case the flag was fixed to the Sphinx mascot on the radiator cap with copper wire, sir. The official number was tied with tapes to the front of the car, be- low the radiator." "And, once fitted, they were readily detachable?" "It would only take a few seconds to get them off, sir." "Very well, then. Now, let us consider how the sub- stitution might have taken place. We will suppose that Lessingham left his car unattended for a few min- utes, during Wednesday night. The individual who stole Mr. Chalk's car, whom we may for the present call the thief, seized his opportunity. "Remember he had several hours in which to pre- pare Mr. Chalk's car to resemble Lessingham's. No doubt he had already removed the brass plate from the dash. He may even have fitted Mr. Chalk's car with registration number plates bearing Mr. Lessingham's number, ZV nine six nine four. All he had to do there was to transfer the official number card, and the Rally flag, which, as Harold has told us, would be the work of a few seconds. "He, then, one must presume, drove away in Lessing- ham's car. Lessingham, on returning to the place where he left his car, would have no suspicions of the change that had been made. It was dark, of course, and any distinctive marks, such as scratches on the paint work and upholstery, would not be noticed. The thief would, of course, have transferred any baggage, such as maps, from one car to the other. Lessingham 138 DR. PRIESTLEY LAYS A TRAP drives away without suspecting the trick that has been played upon him. Is there anything impossible in this hypothesis?" It wrs Hanslet who replied to this question. In spite of the ill grace with which he had consented to listen to Dr. Priestley's arguments, he had gradually become interested. "There's nothing impossible, Professor. The thing might have been done, I'll admit. But you won't mind if I criticize your theory a bit, will you?" "Not if you criticize it intelligently," replied Dr. Priestley, still with a trace of severity in his voice. "I'll try to do so. In the first place, it's almost in- credible that the thief should have come by chance upon Lessingham's car standing unattended. The substitution must have been premeditated. You have realized that yourself, since you say that Mr. Chalk's car may have been already fitted with plates bearing Lessingham's registration number. Doesn't that sug- gest that Lessingham was in the plot? How else could the thief know where his car was to stop, and what his number was?" "I will reserve my answer to that criticism till later. What is your next objection, Superintendent?" "Just this, Professor. If neither Lessingham nor Purvis were in league with the thief, the car must have been left unattended in some lonely spot where he could transfer the flag and number unobserved. This seems rather unlikely." Dr. Priestley turned to Harold. "What have you to say on that point, my boy?" he DR. PRIESTLEY LAYS A TRAP 139 asked. "Well, sir, the only time we left the Armstrong un- attended was while we were in the controls. And then she wasn't exactly unattended. There were plenty of other cars and people about." "That is a very vague statement. Who were these people?" "Other competitors, for the most part, sir. At all the controls there was some enclosed space or park into which competitors drove their cars. There they were left while the driver and passengers signed the route book, snatched a meal, and so forth. Meanwhile other competitors were busy with their own cars, filling up with petrol, or making adjustments." "Did any of your party, at any of these controls, notice particularly what other competitors were do- ing?" "I don't suppose we did, sir. We were too intent upon our own affairs." Dr. Priestley nodded. "That is very much what I imagined," he said. "Now, can you describe to us the conditions at the Moorchester control?" "I'm afraid I can't exactly, sir," replied Harold. "We were so much delayed by the fog that we didn't get there until everybody else had gone. But I can describe the car park there. It was an open space, a sort of courtyard beside the Imperial Hotel. It was a biggish place, with plenty of room, but unlighted. One had to depend on one's own lights to find the way about it. And it must have been very busy earlier in the 140 DR. PRIESTLEY LAYS A TRAP night, for Moorchester was a control for starters from other places besides Bath." "Were other than competing cars allowed in this parking place?" asked Dr. Priestley. "Oh, yes, sir. There were half a dozen or more not carrying flags or official numbers when we were there. I expect that they belonged to the control officials, and people like that." "Now, just one moment. As I understand it, the car that Lessingham was driving and Mr. Weldon's were the last to leave the control. Do you suppose that they all took the road through Westernham?" "All those which had started from Bath, sir, at all events. Some of the others had another control to reach before they entered on the final stage to Tor- quay. The road through Westernham is the most direct between Moorchester and the finishing point." "Then how do you account for the fact that their tracks were not visible on the photographs taken by Sergeant Showerby?" "Because the dew only began to fall about the time of the accident, sir. Cars passing over the dry road be- fore then would leave no visible tracks." "It could be predicted, with some certainty, that Les- singham would take the route through Westernham after leaving Moorchester?" "I think it could, sir. There are, of course, other roads between Moorchester and Torquay. But the one we took is the most obvious, and I expect that nearly all the competitors followed it." Dr. Priestley leant back in his chair. DR. PRIESTLEY LAYS A TRAP 141 "Well, Superintendent?" he asked expectantly. "I see what you're driving at," replied Hanslet. "You're trying to make out that the substitution took place at the Moorchester control. I dare say that it did. What do you think, Mr. Merefield? You've seen the place, and I haven't." "It could have been done, easily enough," replied Harold, with conviction. "We know that Lessingham got there about half past ten. Although the control was not open then, I dare say that a good many cars arrived about that time or soon after. The thief, with Mr. Chalk's car, arrived later. The fact that he had not a flag or official number would not be noticed, or, if it was, his car would be supposed to belong to one of the officials. "He might even be carrying plates with Lessing- ham's registration numbers. He could feel certain that he ran practically no risk of discovery. Nobody would notice that there were two cars in the park with the same registration number. It was nobody's business to look at the registration numbers, for one thing. And, for another, everybody concerned had been on the road for over twenty-four hours. I know I shouldn't have noticed anything if all the cars in the park had been carrying the same number, or, for that matter, no number at all. "The thief could have taken the flag and official num- ber from Lessingham's car and put it on Mr. Chalk's without any difficulty. In the general confusion, no- body would have been a penny the wiser. All he had to do then would be to change the cars round, so that Les- 142 DR. PRIESTLEY LAYS A TRAP singham should find Mr. Chalk's in the place where he had left his own. With cars continually coming in and out, there would be no difficulty about that. And Les- singham, coming out into the dark, not yet thoroughly awake, and in a tearing hurry to get on, would notice nothing." "A most graphic picture of what probably hap- pened," remarked Dr. Priestley approvingly. "By the time that Lessingham came out of the hotel, the thief had already left in Lessingham's car, no doubt. His scheme, so far, had been thoroughly successful." "But what was his scheme, Professor?" demanded Hanslet. "You're asking me to believe in a car thief who must have known Lessingham's intended move- ments exactly, and yet had no connection with him. This remarkable person exchanges the car he has stolen for Lessingham's. He then drives away, and Lessing- ham's car is found in a disused quarry in Somersetshire, completely smashed up, I gather. I think I'm entitled to ask what his scheme was!" "Before I answer that question, Superintendent, how do you reconcile the finding of Lessingham's car with your theory?" "Easily enough. I've maintained all along that Les- singham had associates, that he was the chief of a gang of car thieves. One of these took Lessingham's own car to a depot established for the purpose. Lessing- ham was probably on his way there when he crashed. But as soon as they heard of the accident, the gang got the wind up. They would know that the car that Les- singham was driving would sooner or later be identi- 144 DR. PRIESTLEY LAYS A TRAP Harold. "There you are, Professor. I assure you that there was not a shadow of doubt about it. You'd have spot- ted it at once, if you'd been there with us. If Lessing- ham's business was perfectly straight and above board, why should Orchard have invented this cock and bull yarn?" "For some purpose which we have not yet fathomed," replied Dr. Priestley thoughtfully. "For instance— but you are tempting me to conjecture. Besides, we are straying from the subject. You asked me to out- line the thief's scheme. But first of all, who was the thief, assuming, as I do, that he and Lessingham were not associated in the theft? "We know two things about him, of which the first is this. He must have been acquainted with Mr. Chalk, to the extent that he knew his practice of going to Mr. Catcsby's on Tuesday evenings. More than this, he must have known that he was the owner of a Comet car similar to Lessingham's, and that he was in the habit of leaving his car in Mr. Catcsby's drive. I would point out that it does not follow that he knew Mr. Chalk personally. He may have discovered these data by observation. "The second thing is that he must have known the details of Lessingham's intended schedule. I am quite satisfied in my own mind that the substitution took place in the courtyard of the Imperial Hotel at Moor- chester. The thief must therefore have known the in- tended time of Lessingham's arrival and departure. I do not press the point of Mr. Chalk's car having been DR. PRIESTLEY IAYS A TRAP 145 stolen at a time when Lessingham may have been pass- ing near Denham. This, very possibly, was what is termed a coincidence. But I have my own reasons for believing that he knew the route which Lessingham was to follow between Moorchester and Torquay. Finally, he was sufficiently familiar with Lessingham's car to know the registration number." "In that case, he must be a pretty intimate friend of Lessingham's," remarked Hanslet. "Probably. Now, what was his scheme? I am con- vinced that he did not steal Mr. Chalk's car for profit. He stole it because he wanted a car exactly similar to Lessingham's. Any one of that particular model would have served his purpose. It was probably Mr. Chalk's habit of leaving his car in Mr. Catesby's drive that in- fluenced his selection of this particular car. "Having stolen it, nearly twenty-four hours must elapse before he could effect the substitution. How he disposed of the car during that period I do not know. He certainly removed the brass plate from the dash, and there is reason to believe that he did something else. But I prefer not to discuss that until further evi- dence is available." Hanslet smiled. "No guesswork for you, Professor," he said. "It comes to this, then. He wanted, for some mysterious purpose of his own, to exchange Lessingham's car for one exactly similar to it. In other words, he wanted to obtain possession of Lessingham's car without its owner knowing anything about it. But what did he want it for? Had it any peculiarity that made it of 146 DR. PRIESTLEY LAYS A TRAP special value to him? In any case, he would not have dared to use it openly for long, for Lessingham would have discovered, by the absence of the stencils, that he was not driving his own car, as soon as he reached Torquay." Dr. Priestley shook his head. "The object of the substitution was not to enable the thief to obtain possession of Lessingham's car," he re- plied gravely. "Then what was the object, Professor? According to you, it seems utterly pointless. Was it a joke or something?" "Anything but a joke. Has it not occurred to you, Superintendent, that the substitution of the cars was the direct cause of the accident which happened shortly afterwards?" "It can't have been, Professor. Mr. Chalk's car was in as perfect condition as Lessingham's could have been. We have the word of the experts for that. Inspector Harraway raised the point, and it has been satisfacto- rily disposed of." "Did the experts see Mr. Chalk's car before the ac- cident took place?" replied Dr. Priestley swiftly. "You have allowed the comparatively simple matter of the theft to divert your attention from the significance of the so-called accident." Hanslet shrugged his shoulders. "Well, after all, motor-car accidents will happen, as we all know." Dr. Priestley rapped his desk impatiently. "Yes, yes, of course!" he exclaimed. "And appar- DR. PRIESTLEY LAYS A TRAP 147 ently coroners exist who are as ready to take accidents for granted as you are, Superintendent. But in this case there can be no shadow of doubt in the mind of any intelligent person that Lessingham was deliberately murdered!" CHAPTER XII If Dr. Priestley had hurled the ink-pot which stood on his desk at him, Superintendent Hanslet could not have been more amazed. "Murdered!" he exclaimed. "Lessingham murdered! How on earth do you make that out?" "Not, as yet, by logical deduction, I confess," replied Dr. Priestley. "There are many steps to be filled in before the argument is complete. But the overwhelm- ing probability is there, for anybody to see." "But who murdered him, Professor?" asked Hanslet, only half seriously. "The only person with him when he was killed was Purvis. You don't suggest that Pur- vis snatched the wheel and drove the car into the ditch, do you?" "I do not suggest anything so ridiculous, but murder can be remote; by which I mean that it is not necessary for the murderer to be present at his victim's death. For instance, I prepare an infernal machine, fitted with a time fuse, and put it in your pocket. An hour later, when we may be many miles apart, the machine deto- nates and kills you. Am I none the less a murderer be- cause I am not present at that time?" "I hope you won't try anything of the kind, Profes- sor. But, seriously, what's that got to do with this Lessingham business?" "This; that I believe that Mr. Chalk's car had been 143 DR. PRIESTLEY LAYS A TRAP 149 converted into the equivalent of an infernal machine, and that it was for that reason that it was substituted for Lessingham's." Hanslet shrugged his shoulders wearily. "We can't go against the evidence of the experts," he said. "Can't you be a little more explicit, Professor?" "Not at this stage," replied Dr. Priestley decidedly. "To you, as an officer of police, I put the matter like this: You have no proof that Lessingham stole Mr. Chalk's car. I think I have demonstrated that the sub- stitution of one car for another, an admitted fact, could have been carried out without Lessingham's knowledge. Harold has shown us the possibility that such a substi- tution could have been carried out at the Moorchester control on the Wednesday night. "Since in any investigation you are bound to con- sider all the possibilities, you must consider this one. The first question you will then ask yourself is, what was the motive of the substitution? And, in seeking the answer to this question, you must bear in mind the fact that, shortly after Lessingham began to drive the sub- stituted car, he met with a fatal accident, the cause of which has never been satisfactorily explained." Hanslet nodded, but for some moments he made no reply. Had anybody but Dr. Priestley expounded such a seemingly far-fetched theory, he would have dismissed it at once without giving it serious consideration. But, from long experience, he knew that even the professor's most startling theories had a way of turning out to be correct. During the conversation that evening his faith in the 150 DR. PRIESTLEY LAYS A TRAP construction which he had put upon the Lessingham case had been rudely shaken. But he was hardly pre- pared for it to take the dramatic form which Dr. Priest- ley had outlined. This was turning the tables with a vengeance! Instead of regarding Lessingham as a criminal he was asked to look upon him as a victim. On the face of it, it seemed absurd. Still— "You can't give me a hint as to who killed Lessing- ham, if your theory's right?" he asked suddenly. Dr. Priestley shook his head. "Not from the facts at present in my possession," he replied. "The discovery of the murderer's identity is, surely, a matter for the police." Again Hanslet nodded, and a second pause ensued, longer than the first. "I tell you what I'll do, Professor," he said abruptly. "Tomorrow I'm going down to this place Slowford. I want to see the quarry where Lessingham's car was found. And I think I'd better arrange for what re- mains of the car to be brought up to London for exami- nation. If that doesn't get me any further, I'll see the Assistant Commissioner, and put this murder theory of yours before him. It's for him to decide if any steps are to be taken in that direction. It's a bit awkward, you see. A verdict of accidental death has already been returned." "It would not be the first instance of an incorrect verdict having been given at an inquest," replied Dr. Priestley. "To cite one instance alone. You know bet- ter than I do that it has been found that a victim, whose death was attributed at an inquest to natural causes, DR. PRIESTLEY LAYS A TRAP 151 has subsequently been found to have been poisoned." "Yes, I know," said Hanslet, without enthusiasm. He rose heavily from his chair. "I'd better be making a move, I suppose," he continued. "Can I look in again in a day or two, Professor?" "You had better telephone first," replied Dr. Priest- ley. "It may save you a journey. I think it is quite likely that I shall be out of London for a day or two." Harold followed the superintendent to the front door. "Where's the old boy off to?" asked the latter, with a shade of anxiety in his voice. "I don't want to lose touch with him, after what he said just now." "I haven't the slightest idea," replied Harold. "It's the first I've heard of his going away at all." But he was soon to be enlightened. When he re- turned to the study after seeing Hanslet out, he found his employer still sitting at his desk, with a map spread out in front of him. He said nothing for a few min- utes, and then looked up. "A change of air would do us both good, my boy," he said benignly. "We might spend a day or two in a bracing atmosphere with advantage. Do you suppose that the Imperial Hotel at Moorchester would be incon- veniently crowded?" Harold with difficulty repressed a smile. So this was the secret of his employer's sudden resolve. "I shouldn't think so, sir, at this time of year," he replied. "Then you had better telephone in the morning, and reserve rooms for us tomorrow night. Do you think that your friend Mr. Weldon could be persuaded to DR. PRIESTLEY LAYS A TRAP 153 ley when he came down to breakfast. "That is most satisfactory," was his employer's com- ment. "I shall be glad if Mr. Gateman comes in addi- tion to Mr. Weldon. We will catch a train which will take us to our destination in time for dinner. Mean- while, there are certain inquiries which I should like you to make for me." So it happened that after breakfast Harold set out for Mr. Chalk's office in the City. Mr. Chalk seemed delighted to see him. "Hullo, Mr. Merefield!" he exclaimed. "Still on the trail, eh? Haven't you brought our friend the superin- tendent with you this morning?" "No, he's out of town today, I believe," replied Harold. "Look here, I only want to ask you one ques- tion. When I was up at the Comet works yesterday, the engineer there pointed out to me that the pin at the end of the steering rod had been renewed. Did you have this done?" Mr. Chalk shook his head. "Not I!" he replied. "I never even noticed that it had been replaced. I've had nothing done to the car since I've had her. She was running perfectly up to the time she was pinched. I only hope she'll be as good when I get her back again. Damn the man who put me to all this trouble, I say!" "Let's hope the superintendent will run him to earth," remarked Harold. "I expect he will.- He's a blend of the strong silent man and the old British bull dog, and that always im- presses me. But about that pin. The Supremacy peo- 154) DR. PRIESTLEY LAYS A TRAP pie must have put it in. They overhauled the car be- fore they delivered it to me, you know. I tell you what. If you're really interested, you can go and ask them. They'll tell you all about it if you give them my card. They're good people, and they know me very well, for I always deal with them. Are you off already? Well, let's go round the corner and have a spot. There's nothing doing in the office this morning." The consumption of the spot occupied a few minutes, and then Harold, having taken leave of Mr. Chalk, set out for Kingston. He found the premises of the Su- premacy Motor Company, and asked for the manager, who glanced at Mr. Chalk's card and immediately be- came communicative. "Always ready to do anything for a friend of Mr. Chalk's, sir," he said. "He's a very good customer of ours. His car was smashed up in the Rally the other day, I hear? Terrible business. Both driver and pas- senger killed, weren't they? Lucky Mr. Chalk wasn't one of them. That's what comes of lending cars to other people." Harold let this distorted view of the accident pass. Since the manager apparently knew nothing of the theft of the car, there was no point in enlightening him. "I wonder if you could tell me exactly what was done to Mr. Chalk's car before you delivered it to him?" he asked. "Nothing much, so far as I remember. We re- painted it, I remember, with Comet grey which we got from the Comet people. A demonstration car soon be- gins to look shabby, you know. I can soon tell you 156 DR. PRIESTLEY LAYS A TRAP been the same colour as the rest of the chassis. We must accept Mr. Chalk's statement that he did not fit it subsequently. "In that case, the new pin must have been fitted be- tween the time when the car was stolen, and the time when the Comet Company's engineer examined it. Why was this done if the steering gear was in perfect order when the car passed out of Mr. Chalk's posses- sion? That is the first question. The second is, what is the exact function of this pin? Perhaps you can explain it?" "I think so, sir. The pin connects the steering rod, which is actuated by the steering wheel, to the front wheels of the car. It is a connecting link between the driver's hands and the pivoting motion of those wheels." "And if the pin were removed?" "The driver would be unable to steer the car, sir. He might revolve the steering wheel, but the motion would not be communicated to the front wheels of the car, which would be free to pivot as they pleased." "That is what I imagined. And yet, the opportu- nity— Well, well, we shall see." Dr. Priestley and Harold reached the Imperial Hotel at Moorchester about six o'clock that evening. Bob Weldon had already arrived, and, after a few words with the professor, he took the opportunity of drawing Harold aside. "Richard's coming down later," he said. "What's on, exactly? I didn't care to ask outright before your old man." Harold glanced round to see that he could not be DR. PRIESTLEY LAYS A TRAP 157 overheard before he replied. "What he means to do, I don't know," he said, "but he's got some plan of his own on. He wouldn't tell Hanslet where he was going. His latest theory is that Lessingham was murdered, and I think he wants to find out how it was done." Bob whistled softly. "Murdered, eh!" he exclaimed. "What will our old friend Inspector Harraway say to that, I wonder. Has the professor broken this to Superintendent Hanslet?" "Yes, last night. Hanslet didn't know what to make of it, quite. He's had news that Lessingham's own car has been found somewhere in Somerset, and he's gone down to have a look see." "While we make sensational discoveries down here. I say we, because I gather I'm to be made use of? The professor wouldn't have suggested my joining the party for the sake of my good looks." "Oh, you'll be made use of, all right, and the Arm- strong too, I expect. Come over here and let's have a cocktail, and I'll tell you what I know of the old boy's theory." Just before dinner they were joined by Dr. Priestley, and half way through that meal Richard arrived. Be- tween them they made a merry party, for Dr. Priestley could get on perfectly well with younger men when he chose. But he steered the conversation away from the object of this meeting, and it was not until after ten o'clock, when the lounge began to empty, that any men- tion was made of Lessingham or even of the Rally. And then it was Dr. Priestley who introduced the sub- .158 DR. PRIESTLEY LAYS A TRAP ject. He did so abruptly, after a glance at the clock. "It was about this time that Lessingham drove up to the control," he said. "I should like to inspect the place where competitors' cars were parked. Will one of you show me the way?" They all rose, and Bob led the Way. "The room used by the control officials was there," he said, pointing to the further corner of the lounge. "We came in by a side door, I remember. That must be it." They passed through the door, and found them- selves on a wide gravel sweep, with a high wall round two sides of it. There were no lamp-posts within this enclosure, which was illuminated only by the light that filtered through the curtained windows of the hotel on one side, and the reflection of the lights of the town on the other. Three or four cars, with their lights extin- guished, were ranged against one side, but until Dr. Priestley's eyes had accustomed themselves to the gloom, he did not catch sight of them. "Looks much the same as when we turned up that morning, doesn't it?" remarked Bob. "I haven't the least recollection of what the place, looked like," replied Richard. "I was walking in my sleep, I believe. But it must have been pretty busy earlier in the night. There's not room for a lot of cars at a time." "You could get a hundred in, I dare say, if you parked them carefully," said Bob. "But with fellows coming and going every moment, there must have been a bit of confusion. The R.A.C. man on duty couldn't DR. PRIESTLEY LAYS A TRAP 159 possibly look after them all. I expect he had his work cut out to keep the entrance clear, as it was." Dr. Priestley listened to this conversation with in- terest. He could well imagine the scene. Cars scat- tered all over the enclosure, their drivers and passen- gers, weary with driving and lack of sleep, moving among them like the figures of a dream. Other cars coming and going, their lights dazzling the already be- wildered throng. The harassed R.A.C. man, hur- riedly giving directions, holding up a stream of arriv- ing cars in order to let a competitor out. And over all a confusion of light and darkness, in which nothing could be distinctly discerned. "This is no doubt where the substitution took place," he said, after a long pause. Bob, who had heard this theory from Harold, nodded approvingly. But to Richard it came as news. "By Jove, sir, I'll bet you're right!" he exclaimed. "It would have been the easiest thing in the world. I don't believe I should have noticed if someone had ex- changed Bob's Armstrong for an old Ford. Until I be- gan to drive, of course. But in this case they were exactly similar. Nobody could possibly have noticed the difference." Dr. Priestley smiled. "We seem to be in agreement on that point," he said. "Suppose we return to the lounge and discuss the vari- ous points involved?" When they had found a quiet corner, the professor gave a detailed explanation of his theory, for the bene- fit of Bob and Richard. CHAPTER XIII On the following morning, punctually at nine o'clock, the party left the hotel in Bob's Armstrong Siddeley. Bob was driving, with Dr. Priestley beside him, map in hand. As they took the road to Westernham, Bob described the incidents of the morning of the Rally. "I was pretty well at the end of my tether, as Harold will tell you, sir. But I do just remember where it was that we first saw the red tail light of the Comet in front of us. I'll show you when we come to it." They drove on in silence for some miles, Dr. Priestley following the road on his map. "It was just about here, wasn't it, Harold?" Bob asked. "Yes, that's right," replied Harold from the back of the car. "I remember that belt of trees on the right." "Thank you, Mr. Weldon," said Dr. Priestley. "Now, will you do exactly as you did that morning, pulling up exactly in the same place as you did then?" Bob began to slow up. "That's the place where the Comet was," he said, after a few seconds. "You can still see where the edge of the ditch is broken away. I kept over to my left, and pulled up by the side of the road. I believe this is the spot to an inch." He stopped the car a yard or two in advance of the 162 DR. PRIESTLEY LAYS A TRAP 163 mark in the ditch. "Then we all got out and ran across to the Comet," he continued. "It was still pitch dark, and we had to use a torch to see what we were doing." "Did any of you notice if there were marks of tires on the road, beyond where the two cars were stopped?" asked Dr. Priestley. Silence followed this question till Bob spoke, half apologetically. "I don't think anybody thought of looking, sir. We were too concerned with what had happened to Lessing- ham and his passenger to think of anything else. I'll admit that, while the other two had gone on to fetch the police, I examined the tracks of the Comet, but of course, they were behind the two cars. It never oc- curred to me to look in front of them." "Perhaps, if you had looked, you would have made an interesting discovery," remarked Dr. Priestley. "The road is fairly wide here, it appears. Would it be possible to turn a car in it without much difficulty?" "Easily enough, sir. We turned this car, when we went with the policeman to the White Hart, and Dr. Mason turned his." Dr. Priestley nodded. He took a pencil from his pocket and made a cross on the map at the point where they stood. "I should like you to look at this map, if you will, Mr. Weldon," he said. "The scale is one inch to a mile. Approximately three miles ahead of us lies Western- ham. Half a mile from here, in the Westernham direc- tion, there is a road branching off to the left, which 1G4> DR. PRIESTLEY LAYS A TRAP leads to a road running parallel with this, rather over a mile away. Do you know that parallel road?" "I've driven over it once or twice, sir. You get a magnificent view from it, looking over towards the sea. If you look at the map, you'll see a crossroads two or three miles out of Moorchester. We passed that as we came along. It was where the R.A.C. scout was stand- ing, if you remember. If we had turned to the left there, we should have come out on the parallel road, which runs along the crest of the ridge. I expect we can see it from here, if we get out of the car." They got out, and Dr. Priestley, looking southward, saw a line of low hills before him. Upon the sky line, clearly outlined against the clouds, was the silhouette of a horse and cart, slowly plodding its way along. "That cart's on the road you mean, sir. It's not a bad road, but it isn't much used now, except for farm traffic. I believe it was the highroad once, before this one was made. But it's abominably steep in places, and the surface is none too good." "I noticed as we were driving here that the ridge is visible nearly all the way from Moorchester. Does the old road run along the crest of it for the whole of that distance?" "Practically. It dips here and there, but it always comes up again." Once more Dr. Priestley studied his map thought- fully. "Besides the crossroads which you mentioned, and the side road which I pointed out, there are two roads, or rather lanes, connecting the two roads," he said, ap- DR. PRIESTLEY LAYS A TRAP 167 , which road we got here by. About a hundred miles from here we ran into fog, as I expect Harold has told you, and lost our way completely. It wasn't until we saw a signpost that we had any idea where we were go- ing, and after that we trusted to them entirely." "How do you explain the apparent fact that Les- singham was not delayed by this fog?" asked Dr. Priestley. "Easily enough, sir. He may have reached here be- fore the fog came on. He was three hours and a half ahead of us at Droitwich, the previous control. Or he may have taken a different route—there are at least a dozen possible ones—and so escaped it." "I see," said Dr. Priestley. Bob turned once more to the map, exploring the various roads into Moorchester. "I believe I've got it!" he exclaimed after a few mo- ments. "I seem to remember that name, Hedgeworth, don't you, Harold? Didn't you spot it on one of those yellow A.A. signs as we came through?" "I believe I do, now that you mention it," replied Harold. "About twenty miles out of here, isn't it?" "That's right," replied Bob, pointing to the map with the stem of his pipe. "This is the road we must have come in by, sir. And it must have been soon after passing Hedgeworth that we struck that patch of wooded country." Dr. Priestley produced his map-measurer. "I make the distance between Denham and Hedge- worth sixty-seven miles," he said. "The thief would have no difficulty in reaching that point before daylight on Wednesday morning. If the theft took place about 168 DR. PRIESTLEY LAYS A TRAP midnight, his journey would have been accomplished during the quietest time of the night. He had prob- ably reconnoitred his route beforehand, with the aid of a map. By the way, were any maps found in the car which Lessingham was driving?" "By Jove, sir, now I come to think of it, there weren't," exclaimed Bob. "I'm quite sure of that. I examined the car pretty carefully twice, first just after the accident when I was waiting for the others to come back from Westernham, and again with Inspector Har- raway at the Central Garage. The route book was there, but no maps. Yet Lessingham would never have started on the Rally without taking maps with him." "Looks as if Homer had nodded," remarked Richard. "In other words, the thief forgot to take them from Lessingham's car and put them in Chalk's when l
