Another ten minutes passed, and hidden again in the shadows of a porch, he was staring now with feverish eagerness at a great, covered motor truck, a furniture van, that was drawn up in front of what appeared to be a truck-man’s office across the street. The driver had gone into the office, but there was the street to cross—and two men were coming leisurely in his direction along the sidewalk. He clenched his hands fiercely at his sides. Here was the chance flaunting him in the face and tantalizing him, the chance that was a far greater chance even than he had dared hope for, and he was powerless to avail himself of it unless those two men passed by before the driver came out again. He could read the name and address in the huge letters on the side of the van. It belonged down on the East Side. This was probably only a small uptown branch office, and the odds were a hundred to one that the van would be going home now. And if the driver took a direct route he was bound to use a cross street that would intersect that lane in the rear of Marco’s, and intersect it within at least a few blocks of the second-hand dealer’s shop. Billy Kane’s hands clenched tighter, and his face was strained and drawn, as from his hiding place he alternately watched the van and the two men. Those few blocks through a lane would be nothing! God, if he could only reach Marco’s—and a coat! A coat! It seemed an absurd thing to be of such moment—a coat! But it meant life or death. A coat would cover his blood-stained shirt, and he would be able to move with freedom enough to give him at least a fighting chance, and——
The two men had passed by; there was no one else in sight. He waited another moment until they were still further away—and then, in a flash, Billy Kane was across the road, and had swung himself over the tail-board into the van. It seemed like some vast cavernous place here inside, for the van was empty, save for what appeared to be, as nearly as he could make out in the gloom, some large pieces of crated furniture piled at the front end just behind the driver’s seat. Billy Kane’s eyes swept the interior anxiously—and the drawn, strained look in Billy Kane’s face relaxed. By lying flat on the floor of the van the driver would hardly be likely to notice him in any case; but, to make assurance doubly sure, some bits of sacking, evidently used to wrap around and protect furniture from being scratched and marred, were strewn about on the floor. Billy Kane pulled off his slouch hat, that had been jammed down over his eyes, drew a piece of the sacking over him, and lay still.
And then presently he heard the driver come out from the office. The man climbed to his seat. The van jolted forward. Billy Kane’s hand, under the sacking, felt tentatively over his shoulder. It was paining him brutally, and was burning and hot, but it seemed to have stopped bleeding, and the sense of nausea and giddiness had passed away. It was a flesh wound only, probably; or, at least, the bullet had not fractured any bone, for he could move both shoulder and arm readily.
And now, safe for the moment, Billy Kane’s mind was back on the events of the evening; and for a time grief for the man he loved had its sway; and then came fury, pitiless and remorseless, and a cry in his soul for vengeance; and then a quiet, measured analysis of every detail, an analysis that was deadly in its cold, unnatural calm. Jackson’s acts in that back passageway, Jackson’s possession of a revolver, and Jackson’s words at the end stamped the footman irrevocably as being one of the men in the murder plot. And with Jackson’s guilt established as a premise, the rest unravelled itself step by step, clearly, logically, irrefutably.
David Ellsworth’s deductions had proved themselves in ghastly truth. The letter had been written as the initiatory step toward incriminating him, Billy Kane, in the robbery that was to follow; and this demanded, even as he had argued before, that the vault and safe combinations should be known to a third party. Who knew them? The answer came now quickly and emphatically enough—someone within the house—Jackson. He remembered now, though he had paid no attention to it before, that Jackson had been in the library on several occasions when he, Billy Kane, was opening the vault. It had probably taken the man a month or two, perhaps more, watching both David Ellsworth and himself at every opportunity and with infinite patience, to pick up little by little, possibly but a single number or turn at a time, the combinations—but he had undoubtedly accomplished it finally.
The original plan had certainly not contemplated the murder of David Ellsworth, for the letter was primarily intended to make the old millionaire one of the first to accuse him, Billy Kane, of the crime—there having been left on the scene of the crime, of course, in that case, as David Ellsworth had also reasoned, some further damning evidence of his, Billy Kane’s, supposed guilt. But the changing of the combinations had completely upset that original plan. Who was it, then, who knew that the combinations had been changed? Again the question answered itself almost automatically. It must have been someone in the house at the time, and someone who was both listening and watching—Jackson. True, David Ellsworth had looked out into the hall, and had opened the door and looked into the unlighted stenographer’s room, but he had done it only cursorily, and Jackson all the time might well have been hiding in that room—in fact, must have been hiding there.
The rest was self-evident. Without the combinations they were helpless, but the new combinations were on a card in David Ellsworth’s pocket. It had been necessary, then, only to add murder to the theft, employing as accessories the card, the letter, the button and the black silk loop, in order to seize the opportunity of the moment; for, the card bearing the combinations once destroyed or out of reach, the months of work that had been put in to secure the old combinations would have to be repeated to obtain the new—and with very little likelihood of success, since Jackson would know that David Ellsworth’s suspicions were thoroughly aroused.
The van rolled rapidly downtown. Billy Kane, peering out from under the sacking, kept watch on the streets through which he passed. But his mind was still busy with its problem.
Jackson’s act in accosting him on the corner, and afterwards luring him by suggestion to the rear of the house, had puzzled him at first, but that, too, was clear enough now. There was a grain of truth in what the man had said about giving him a chance, though Jackson would care little enough whether he ultimately got away, or not. Jackson’s idea, or perhaps the idea of a keener brain behind Jackson, was to prevent him, Billy Kane, from entering the house at all, and so, by inducing him to run for it, to corroborate the evidence of guilt against him, in which case, being a self-elected fugitive, he would be doubly condemned if eventually caught. On the other hand, if he refused to listen and insisted on entering the house, as they were afraid he might do, they meant to see to it that his entrance was made by apparent stealth, and here again he but added the final touch to the evidence against him, and discredited himself beyond any hope or possibility of recovery. Jackson had taken no personal risk or chance in doing this, as far as the police were concerned; and it was evident now that Jackson had meant to kill him there in that back passageway should he, Billy Kane, persist in refusing to run. The case and all investigation would have ended automatically if he, Billy Kane were killed under such circumstances. It was all simplicity itself! Jackson had only to call for help, as he had done when the issue was forced by that approaching footstep, pretend that he had discovered him, Billy Kane, creeping into the house, and had rushed upon him—that he, Billy Kane, had drawn the revolver, but that in the struggle had been shot himself. With the evidence as it stood, with his, Billy Kane’s guilt so apparently obvious, Jackson would not only have been believed, but would have been rewarded and lauded as a hero.
Still the van rolled on—mostly through deserted streets, for the traffic was light at that time of night. Perhaps another twenty minutes passed. Then Billy Kane began to edge toward the rear end of the truck. He was in the East Side now, and approaching the neighborhood of Marco’s second-hand clothing store.
