The Cadger’s “see youse later,” then, was to be taken literally, and not, as he had supposed, as simply a common and slang expression of adieu! Billy Kane looked at his watch. It was not quite eight o’clock. There was an hour, then, before the Cadger and this Gannet, another of the Cadger’s ilk, would report here ready to follow his leadership in a burglarious raid. Billy Kane stood up; and, in a sort of mechanical and reassuring inventory, his hands felt over the outside of his pockets, over the skeleton keys they contained, the steel jimmy, the flashlight, the automatic, and the soft, slight bulge made by the neatly folded mask—and, too, over another bulge that was made by a certain chamois pocketbook. This latter brought a frown. He had not found a way yet to return Vetter’s diamonds. It wasn’t so easy a thing to do when, if the Rat’s hand showed in the matter, it was certain destruction for the Rat, alias Bundy Morgan, and, for the moment, alias Billy Kane! But Vetter and Vetter’s diamonds were extraneous things just now, weren’t they?

He extinguished the light, crossed to the door, unlocked it, stepped out, locked the door behind him, made his way up the steps, and started briskly off along the street. He did not know what the contents of that “manila envelope” were, nor who Dayler was, nor the Crime Trust’s motive—he was supposed to know all that—he knew only that there was some devil’s scheme on foot that would be worthy of the Crime Trust in its scope and proportions. And the Crime Trust did not interest itself in little things!

[XVII—THE MAN WITH THE CRUTCH]

Billy Kane smiled with grim irony, as he walked rapidly down the block. She was not here to-night with her cool, contemptuous voice bidding him to do this thing. It was evident, therefore, that she was not quite as infallible as she apparently believed herself to be! For once, she was not acquainted beforehand with the Crime Trust’s movements, it seemed! Perhaps it was because, for once, the Rat might not have had anything to do with originating the plan that was afoot to-night, for she had certainly always appeared to be thoroughly informed where the Rat was concerned!

He shrugged his shoulders suddenly, dismissing her from his thoughts. He would better concentrate his mind on the work in hand! The secret lay in the manila envelope. That the envelope contained something of great value, or was of great value to someone, was obvious; to Dayler, probably, since it was in Dayler’s carefully guarded possession. He shrugged his shoulders again. He could tell better about that in the course of another hour—when the envelope was in his pocket instead of Dayler’s safe! To balk this organized gang of super-criminals was sufficient for the moment! Once more his shoulders lifted. He perhaps was not even entitled to any great credit to-night in fulfilling his “moral obligations!” For once, there appeared to be neither any great danger, nor any great difficulty. The house was empty; it was not very far away; he had an hour in which to work undisturbed; and at the expiration of that time he should be back in his room, and ready to set out with the Cadger and Gannet to rob an empty safe. If he with the two men then entered the house, and, for their pains, found the manila envelope already gone, certainly there could be no suspicion to rest upon him!

Billy Kane had reached the Bowery now. He went in through the side entrance of a corner saloon. Here, a minute’s search in the telephone directory supplied him with the number of Dayler’s house on Ninth Street. After that, he made his way over to Washington Square, crossed the Square, gained the lower end of Fifth Avenue, practically deserted now at this hour, and, a moment later, turning into Ninth Street, headed down the block in the direction of Sixth Avenue.

It was one of the old aristocratic neighborhoods of New York, but changed now a great deal with the changing years. What had once been classed as mansions had in many cases been metamorphosed into lodging and boarding houses; but the “mansions” were still here, big, substantial, commodious stone dwellings. Nor had the boarding houses entirely ousted a certain unobtrusive type of wealth and means from their midst, and it argued not at all that this Dayler, for instance, because he had his residence here, was not well to do, even exceedingly well to do.

The street was quiet. Billy Kane located the house he sought. He passed by it, noting that it had a basement entrance, a flight of stone steps to the front door, that it was entirely in darkness, and, returning, he mounted the steps quietly and without any attempt at concealment, found the outer vestibule door unlocked, opened it—after making pretense of ringing the doorbell for the benefit of anyone on the street who might have paid him any notice—stepped inside, and closed the door behind him. The inner door was locked. His skeleton keys came into play. Still far from an adept in their use, he was several minutes at this work. Then he stepped forward into the hall of the house itself.

His flashlight stabbed a lane of light through the darkness. The stairs leading to the upper floors of the house were ahead of him and on his right; on his left, opening off the hall, which seemed to run almost the depth of the house, were several doors, all of which were closed. The house was empty, the cipher message had assured him of that, but nevertheless he moved now with extreme caution to the first door on his left. He knew nothing of the plan of the house, but it was at least logical to assume that the library was on this floor, and the library was the objective of his search.

He opened the door slightly, quietly, then drew sharply back, and stood tense and motionless, listening. There was a dull, faint glow of light in there, not as though the room itself were illuminated, but as though the light came from, perhaps, another room beyond. But there was no sound. A minute passed, and still he stood there, alert, his ears strained to catch the slightest noise. And then, reassured, he pushed the door wider open, and stepped over the threshold. That a light might have been left burning, either intentionally or inadvertently, presented in itself nothing of the unusual, or——
