Billy Kane swung himself up and over a high fence, and dropped noiselessly to the ground on the other side. He found himself in a yard that, even in the darkness, he could make out was strangely restricted in area. A few feet in front of him was the wall of the building itself. He crept forward, skirting along this wall. There was no window, but opening almost on a level with the ground were shuttered French doors. He continued on, rounded the angle of the building, and suddenly stooped down in a crouching posture. There was a window here just above his head, and from it came a meager gleam of light. His eyes grown accustomed to the darkness, he could distinguish his surroundings a little more clearly now. The yard here, a narrow strip of it paralleling the side fence, seemed to run back quite a distance, taking up a jut in the building. They had puzzled him, those shuttered French doors where logically he had expected to find an ordinary back door and porch, but it was obvious now that the “back room at Jerry’s” was an addition that had been built onto the house, extending almost to the fence in the rear.
The window beneath which he crouched was shoulder high. He straightened up. The light came through slightly parted, heavy portières. He felt the blood quicken suddenly in his veins. He could see in quite well. There were two men in the room—Karlin, and another man whom he did not recognize. The room was luxuriously, if somewhat garishly furnished. A green baize card table, with several unopened packs of cards upon it, stood in the center; there was a blue-and-gold Chinese rug with a huge dragon pattern upon the floor; and at one side a large buffet groaned under a load of wine and whisky bottles, bowls of fruit, and refreshments of various descriptions. The two men were talking earnestly. Karlin pulled out his watch, and scowled.
Billy Kane’s lips tightened. He could see, but he could not hear. He took his penknife from his pocket, and slipped the blade under the window sill. If he had luck, if the window was not locked, he—ah!—his breath came in a soft, long-drawn intake—the window gave slightly under a cautious pressure. An inch was all that was necessary, half an inch even. The window went up by infinitesimal fractions of that inch.
Billy Kane returned the penknife to his pocket. He could hear them now. Karlin was speaking; and the other man, it appeared now, was the proprietor of the place, Jerry, the ex-croupier of Monte Carlo.
“What’s the matter with you, Jerry—getting nervous waiting?” said Karlin curtly. “Well, forget it! This is the Rat’s plan—and that ought to be good enough, what? Nothing is going wrong, nothing can go wrong. Certainly, the police will close you up for a month, but that’s all there is to it, so far as you are concerned. They have nothing on you. That’s the inside of the whole thing—that the killing is done in an unpremeditated, drunken brawl over cards—that it just happened—just an untimely end without any other strings to it! There’s no reason why you should lose your nerve—your story is straight. Young Merxler came here often. He gives a little party here to-night. Neither you nor your doorkeeper knows a damned one of his guests. He vouched for them, and that’s all you know. You heard a row in here, then a revolver shot, and when you got here the table was upset, wine, cards and glasses all over the place, the boys beating it out through the French doors there, and young Merxler dead on the floor. You just notify the police. Your loss through being closed for a month makes it a cinch your story’s straight—you don’t have to tell the police that your share of the split is the best bet you ever made in your life! Let me do the worrying! I’m the one who’s taking the risk. I’m the one who’s been showing a seamy side to Merxler in confidence lately. I’m the one who’s invited him to the party that the police will be told he was giving. You can leave it to me that nothing goes wrong. I’ve got my own skin staked on this. There won’t be any mistake made—dead men can’t talk. The only thing I’m bothering about is what is keeping Bull McCann. He might——”
Billy Kane drew suddenly back from the window, and crouched down again against the wall of the building. Someone, unless he were curiously mistaken, was out there in the lane at the rear of the place. He was listening intently now—but there was a strange turmoil in his brain that seemed somehow to divide his attention, that had made his act of caution one that was almost purely automatic. Murder! That casual discussion of murder! There was something within him, soul deep, that he could not quite analyse—save that it seemed a lust for murder was upon him too, possessing him, engulfing him. Would that be murder? Was it murder to crush out the life of a poison-fanged snake! There was a fury upon him, but a most strange fury, a fury that was utterly cold—and utterly merciless. Murder! Yes, he knew now beyond question that there was to be murder, that the stage for it was set with a devil’s craft, with the craft of the Rat whose identity he had assumed; that it would appear on the face of it nothing more than quite a logical outcome of the life led by young Merxler, that there would appear to be no connection whatever with young Merxler’s death and what was to follow—but what was it that was to follow? How, in what way, was this murder, in dollars and cents, to show a profit at the next meeting of that unhallowed directorate of crime? How did Karlin——
Strange how his mind should isolate itself from his immediate surroundings, and yet leave him fully conscious of those surroundings! He was still listening—listening intently. There was no mistake. A boot scraped against a board. Someone was climbing the fence. Came then the soft thud of feet dropping to the ground, and now a quick step across the yard.
Billy Kane’s revolver was in his hand. If the newcomer came around the corner of the house, dark as it was, it was almost certain that—no! The other had halted evidently before those shuttered French doors, and was rapping softly—three raps, a single rap, two raps. The raps were repeated. Someone moved swiftly across the floor of the room. There was the faint clash of portière rings, and the sound of the French doors being opened.
Billy Kane was at the window again. A third man was in the room now. Karlin was speaking sharply.
“You’ve been a long time coming, Bull!”
