When the Duke of Beaumanoir found himself alone in the railway carriage after Alec Forsyth's departure he sank back in his corner with a certain sense of relief. The events of the last twenty-four hours had filled him with a very sincere regard for his cousin Sybil, and he had not much faith in the assurance given him by General Sadgrove that his journey down to Prior's Tarrant would be free from danger. His past experiences led him to expect that the terrible Ziegler and his myrmidons would be more than a match for the shrewd but somewhat out-of-date Indian officer, and if there was to be an "episode" on the railway he would be glad to think that it could not now plunge his plucky young cousin into mourning for her lover.

"She is a girl in a thousand," he murmured, as he lit a cigarette; "I should never forgive myself if I were the means of making her a widow before she is a wife. If, as I half suspect, Alec's detachment was effected by a ruse on the part of the graybeard at the Cecil—well, I take off my hat to that gentleman for his consideration."

As the train gathered speed, rushing through the twinkling suburban lights, the Duke put his feet on the opposite cushions and reviewed the situation—calmly, but always with but slender faith in being able "to worry through" with his life. That had really become quite a secondary object with him, so far as his personal safety was concerned; yet his present attitude was to escape the attentions of Ziegler long enough to convey a warning to Senator Sherman of the plot against him. Whether his nerves would be proof against the strain till the Senator's arrival at Liverpool was a phase of the case which he did not care to contemplate too closely.

Ziegler, he felt sure, would have grasped the position to a nicety, and would use every device in his apparently limitless repertoire to give him his quietus before Leonie's father set foot on shore. It might well be that another attempt would be made on him before he reached the sheltering zone of Prior's Tarrant, wherein General Sadgrove had promised him safety.

His reflections were cut short by the slowing down of the train for the stoppage at Kentish Town, and the Duke's sensations at that moment hardly presaged a comfortable journey for him, brief though it would be. The compartment was labeled "reserved," it was true, and the guard had been tipped to see that the legend was respected, but that stood for little when people of the Ziegler type were on the move, and he looked forward with dread to the future stoppages if his heart was to thump like this.

Which is a study in the quality of fear, for Beaumanoir was of the kind that leads cavalry charges to visible and certain death with gay recklessness.

The present trouble passed, however, for the guard hovered round the carriage and gave no chance to invaders, who in any case would have had some difficulty in effecting an entrance, as the door was locked. The train sped on again, out into the country now, through the balmy summer night, and Beaumanoir breathed more freely. One of the dreaded stoppages was notched off the list.

So, too, were Hendon and Mill Hill safely negotiated, and Beaumanoir was able to contemplate the slackened speed for Elstree with greater equanimity. As before, the guard's portly form loomed large outside the compartment the moment the train stopped, and so doubtless would have remained had not a loud, imperious voice on the platform summoned him to a divided duty.

"Here, guard! What are you about there? Hurry up now, and open this door!" came the choleric command.

With a deprecatory glance at the Duke's carriage the guard perforce hurried off, and Beaumanoir peered out of the window after him. The official had gone to the assistance of a tall, well-groomed gentleman, who, with an air of irritable importance, was fumbling with the door-handle of a first-class compartment some way along the train. The traveler was of the type that secures the immediate respect of railway servants—dressed in brand new creaseless clothes, every immaculate pocket of which suggested the jingle of half-sovereigns. A man carrying a yellow hatbox and a rug lurked deferentially behind the magnate and cast reproachful glances at the guard, who was now thoroughly alive to his opportunities and opened the door with a flourish. The tall man, whom Beaumanoir took for a brother duke, or at least a director of the line, stepped with dignity into the compartment; the menial handed in the hatbox and rugs, and sought a second-class carriage; the guard waved his lamp, and the train moved on.

Beaumanoir withdrew his head and sank back in his corner, catching just a glimpse of the guard preparing to spring into his van as it neared him. The station lights flashed past, and the long line of carriages swung into the outer darkness, the little diversion of the important passenger leaving Beaumanoir amused and comforted. To the man who had tramped his weary way along the Bowery to his five-dollar boarding-house within the month this exhibition of class privileges and distinctions was breezily refreshing, seeing that he was now in a position to claim them himself.

Immunity from danger through four suburban stations had brought a delicious sense of calm, and as he leaned back he thought how nice it would be to live the life of an English nobleman, free from all sordid cares and humiliations. And if he could wake up at the end of a week and find that his entanglement was all a nightmare, or, at any rate, that Ziegler's bark was worse than his bite, and that Senator Sherman had safely deposited the bonds at the Bank—well, in that improved state of things what was to prevent his asking Leonie to share his new-found privileges?

Then, suddenly, the icy finger touched his heart again. As the blue wreaths of cigarette smoke in which he had conjured up this alluring vision rolled away he became conscious that his gaze, hitherto absorbed and preoccupied with day-dreams, was in reality riveted on a material object under the opposite seat. A very material object indeed—no less than the heel of a man's boot.

At sight of this disturbing element Beaumanoir's sensations were of a mixed order. First of all, he could see so little of the boot that he could not be sure that there was a man attached to it, though the presumption was in favor of that supposition, for he was quite certain that it had not been there long, or he would have noticed it before. He guessed, so alert had his mind become under stress of emergencies, that the wearer of the boot had got into the compartment on the off side while he himself had been looking out of the window in Elstree station.

But if so, and the man had invaded his privacy with sinister design, why should he have plunged at once into a position of utter impotence? No one flattened out under the low seat of a first-class railway carriage is capable of active violence without a preliminary struggle to free himself, during which he would be at the mercy of his intended victim. The only design that Beaumanoir could attribute to him was that he would presently wriggle to the front and use a pistol.

He sat and eyed the motionless boot, and then an impulse, swift and irresistible, seized him.

"Come out of that, you beggar!" he cried; and, stooping down, he gripped the boot, wondering whether he was to be rewarded with a haul or whether he would have to laugh at himself for grabbing someone's discarded footgear. But the first touch told him that here was no empty boot, and, his fingers closing on it like a vise, he put forth all his strength and dragged its wearer, snarling and spluttering, out on to the open floor. There was no sign of a pistol, but as a measure of precaution Beaumanoir pulled out his own Smith and Wesson.

"Get up and sit in that corner," he said sternly, eyeing the puny form of the invader with curiosity. Open violence at any rate was not to be apprehended from the stunted little figure of a man who coweringly obeyed his order.

But as his captive turned round and showed his sullen face the Duke knew that this was no mere impecunious vagabond, sneaking a cheap railway journey. His fellow passenger was part and parcel of the peril that menaced him—had, in fact, been a fellow-passenger of his before. For the wizened, mean-looking face was the face of the spy Marker, who had been pointed out to him by Leonie on board the St. Paul, and who had afterwards shadowed him to the Hotel Cecil on landing.

"So we meet again, Mr. Marker," said the Duke with pleasant irony. "I should have thought that your friend Mr. Ziegler could have provided you with a railway fare rather than let you travel like a broken racing sharp—under the seat."

The fellow blinked his ferret eyes viciously, but began a futile attempt at prevarication. "My name, I guess, ain't Marker, and I never heard of anyone called Ziegler," he whined.

"Very possibly your name may not be Marker, though you booked under it on the St. Paul; but you are undoubtedly acquainted with the old rascal at the Cecil who calls himself Ziegler," Beaumanoir retorted.

"You seem to know a powerful sight more about me than I know myself," was the sullen reply.

Beaumanoir made a long scrutiny of the weak but cunning countenance of the spy, and he came to the conclusion that this was one of the underlings of the combination, to be trusted only with minor tasks in the great game. His presence there under the seat of the compartment was the more unaccountable, since he was not the sort of creature with either nerve or physique to murder anything stronger than a fly.

"Look here, my good chap," said Beaumanoir with tolerant contempt, after, as he thought, gauging Mr. Marker's caliber. "You've got a bit out of your depth with the people you're trying to swim with. Why not chuck Ziegler and Co. and come over to me? I'll make it worth your while."

But the only response was a dull shake of the insignificant head and the sulky rejoinder: "I don't know what you're getting at, Mister. I'll chuck anybody you like and come over to you with pleasure if you will stand the price of a ticket to St. Albans."

The persistent denial was as absurd as the suggested reason for his presence under the seat, and Beaumanoir began to lose patience. "I suppose," he said, "that you will maintain that you did not go to Mr. Forsyth's chambers in John Street last night under the pretence of being a chemist's messenger?"

"Never been in John Street in my life," came back the pat and obvious lie.

It seemed useless to argue further, and Beaumanoir preserved silence till the train ran into Radlett Station, when he put into practice the course he had decided upon. At least he would force the creature to disclosure and put him to some inconvenience, as it was possible that thereby he might disconcert his plans, whatever they might be. Lowering the window, he called to the guard, and informed the astonished official that he had found a man traveling under the seat without a ticket.

Then uprose the righteous wrath of the guard, who had Mr. Marker by the collar in a trice and twisted him out on to the platform with the sharp demand:

"Now, young man, your name and address, and quick about it."

"What for?" inquired Marker, openly insolent.

"Defrauding the Company by traveling without previously paying the fare, contrary to By-law 18."

The spy broke into a jeering cackle. "You've only got his word for it that I haven't got a ticket," he replied. "I nipped under the seat because I thought he was a lunatic, and a gent can travel that way, I reckon, if he's paid his shot. Here's the ticket, Mister. I'll make tracks to another carriage."

With which he produced a first-class ticket all in order and walked off along the platform, leaving the Duke and the guard looking after him, the former with a curious smile, the latter with dismayed perplexity.

"Well, of all the funny games!" exclaimed the official. "He must have got in at Elstree while I was attending to that there toff, and blessed if he ain't scooting into the same compartment with him now. Your Grace will understand that I couldn't interfere with him, seeing that he had a ticket and you didn't prefer no charge?"

"All right, guard," replied Beaumanoir, with his weary smile. "It really doesn't matter. He seems to have taken me for a madman, while I took him for a dead-head, that's all. These little misunderstandings will arise, you know. We're behind time, eh?"

Taking the hint, the guard retired and started the train, Beaumanoir resuming his seat in a frame of mind only to be described as mixed. He stared out into the gloom of night, wondering what was to come next. His little stratagem had succeeded, in so far as it had revealed Marker as the possessor of a ticket, and therefore as presumably charged with some design against himself, though it had shed no light on the nature of that design. But the adroitness with which the wretched spy had extricated himself made him gnash his teeth because of the impudent reliance on his inability to assign a reason to the guard for fearing an intruder. That in itself was clear evidence that Mr. Marker was under the seat with a very real purpose.

Had that purpose been entirely thwarted by his discovery? was the question which buzzed through the Duke's brain to the tune of the rolling wheels. There had been an air of insolent confidence in the fellow as he showed his ticket and walked away which hardly tallied with total discomfiture. And then, mused Beaumanoir, was there not ground for further apprehension in his selection of a fresh compartment and a fresh traveling companion? Could it be that "the toff" who had entered the train at Elstree was an accomplice, and that Mr. Marker had gone to report to him and concert new measures? It might well be so, for, whether wittingly or no, the swaggering passenger had certainly caused the diversion which had enabled Marker to open the door on the off side and creep under the seat.

The reflection that the spy might have confederates on the train did not add to Beaumanoir's equanimity, and at the next stop he let down the window again and peered along the line of carriages. Sure enough, he caught a glimpse of a head protruding from the compartment into which Marker had disappeared—not the head of Marker himself, but of the imperious person who had played the magnate and distracted the guard. The head was instantly withdrawn, but it had done a useful work in convincing Beaumanoir that he was really an object of interest in that quarter, and not to Marker alone.

"I wish they would do something and end this beastly suspense," the hunted man muttered to himself as the train moved on once more; "though, for the matter of that, they can't do anything till I get out at Tarrant Road—unless they openly come to the door and shoot me at one of the few remaining stoppages."

But he was soon to learn that stations were not to be the only stopping-places for the 8.45 that night. It had come to a steep gradient, up which it was plodding laboriously, when suddenly there was a bumping thud that hurled Beaumanoir on to the opposite seat; the wheels screeched on the metals as if in agony; a tremor as of impending dissolution quivered through the framework of the carriage, and the train jerked to a standstill.

Beaumanoir had the door open instantly with his own private key, and clambering down on to the side of the line nearly fell into the arms of the guard, hurrying from the rear van towards the engine.

"Run into an obstruction, I expect, your Grace—nothing very serious, I hope," panted the guard as he went scrunching over the ballast to the center of disaster.

People were swarming out of the carriages, all of them evidently more frightened than hurt, and Beaumanoir strained his eyes through the leaping, scuffling figures to the compartment occupied by his enemies. Yes, there they were, and apparently the thing was to be done in character to the last. The tall, well-dressed man opened the door, called "Guard!" in the same old tone of importance, and, getting no response, began to leisurely descend on to the permanent way, followed by Marker, who feigned to hold no converse with him. At the same time there hastened up the man who had handed in the hatbox and rug, and then the three were swallowed up in the shadows beyond the radius of light from the carriage windows.

For the night had fallen inky dark, and outside that narrow band of artificial light all was as black as the nether pit. Shrieking women and agitated men appeared for a moment on the footboards and disappeared, directly they had traversed the short zone of light, into the outer gloom of the waste ground at the side of the railway.

Casting a comprehensive glance at his surroundings, the Duke saw that the accident had occurred at a lonely spot where the line was hemmed in on either hand by dense woods running right up to the rail-fence that bounded the track. Instinct prompted him to quit the dangerous proximity of his own compartment, and at the same time he desired to ascertain how long the delay was likely to last. This he could only do by proceeding to the front of the train, but to reach the engine would entail passing the place where the mysterious three lurked in the shadows. In order to avoid them, therefore, he darted across the zone of light, hoping to escape observation, dived under the train, and made his way forward on the other side of the line, shielded from his foes by the carriages.

One glance at the derailed engine sufficed to show him the nature of the accident, and to inform him of the reason for it. A barrier composed of baulks of timber, supplemented by heaped-up ballast, had been built across the six-foot way, and from the excited remarks of driver, stoker, and guard Beaumanoir gathered that the locomotive was so damaged that even when the obstruction was removed it would be unable to proceed under its own steam. The passengers would have to wait till a relief train came along, unless they elected to trudge three miles to the next or the last station.

It was all too plain to Beaumanoir that here was no accident at all, but an outrage designed to strand him in that lonely place, where amid the darkness and the confusion murder would come easy. The choice of the locality, half-way up a steep gradient where the speed would be reduced to a minimum, pointed to no desire to injure the passengers generally; indeed, there would have been an obvious intention to avoid a really perilous collision, seeing that some of the conspirators were on board. He could pretty accurately gauge Marker's functions now. The spy was to have kept close to him after the "accident," so as to signal his whereabouts in the darkness to the more active members of the gang.

The emissaries of Ziegler would have to dispense with that aid now, but still Beaumanoir could not shut his eyes to his imminent peril. The three who had traveled in the train were on the other side of the line, but the contingent—there would be at least two of them—who had wrecked the engine were probably lurking somewhere near. He could have no assurance that they were not at his very elbow, stealing on him through the dense undergrowth that fringed the fence.

A shout from the guard to the passengers congregated behind the train told him that at least half an hour must elapse before they could be picked up and carried on, and he at once decided that to stay at the spot would be intolerable. He should go mad if he remained at the mercy of invisible adversaries whom he could not hit back. If they would only come out into the open, in a body if they liked, so that he could empty the six chambers of his revolver into them before he went down, he would take his risks gladly; but to stand still in the dark, not knowing how soon a stab in the back would be his fate, was the thing too much. There and then he ended the situation by climbing the fence and plunging into the wood.

He had not taken six steps through the brambles when from the pitch darkness ahead a low, flute-like whistle sounded, to be instantly answered by the cracking of a twig a little to the right of him. His present intention to quit the scene and make his way to Prior's Tarrant on foot across country had evidently been foreseen and provided for. Those bushes were occupied, and his retreat at that point was cut off. He clambered back on to the railway, and, running as hard as his lameness would allow, close to the fence, he again essayed the wood two hundred yards ahead of the engine. This time he won free into the tangle of the copse without any sign of pursuit, and presently came to an open "ride" where progress was easier.
