His mind was clear now and working in lightning flashes. His assailant had been the one man in the world upon whose throat he had prayed to get his fingers—the Man with the Crutch! Well, his fingers had been there, only he had been, at a disadvantage, weak and dizzy from the blow from that thing there, and—yes, this was curious too! He was watching the two men, his automatic covered them unswervingly; but out of the corner of his eye he could not help but see that red patch on the floor beside him, that looked like an ordinary flannel chest protector, and to which the cord that he had torn from his antagonist’s neck was still attached. He reached for it and thrust it into his pocket, as he rose slowly, and a little unsteadily, to his feet.

He eyed the two men now for a long calculating second. Yes, his brain was quite clear now—exhilaratingly clear. And the mental exhilaration seemed to bring in its train a new physical strength as well. In a flash he saw the way out now, and with it, too, the means of slipping Barloff’s self-knotted noose around the miserly old Russian’s throat. But he must work quickly. There was not an instant to spare. This officer could not have come in answer to Barloff’s telephone call, for he realized that, long as it had seemed, his fight here in the room could not have lasted in reality more than two or three minutes, and it had begun almost on the instant that Barloff had run from the house. There would not, therefore, have been time for the telephone call to have been answered, for the nearest police station was too far away, and besides, in that event, there would have been more than one officer. Barloff had probably encountered the policeman out on the street, and, carrying out his devilishly inspired plan, had poured his story into the officer’s ears, and rushed the other back to the house. But in that case, the men from the station would be on their way here now, and the leeway left him, Billy Kane, in which to act must, even now, be narrowed to the very perilous margin of but another four or five minutes—perhaps less!

“Move to the wall, face it, and keep your hands up!” ordered Billy Kane curtly.

The officer, with a chagrined scowl and a shrug of his shoulders, obeyed. Barloff, white and trembling, and thoroughly frightened, needed no urging.

“You’ve got the drop on me,” snarled the officer. “But don’t worry, my bucko, I know who you are! That mask ain’t doing you any good! There’s a free ride and board coming to you again!”

Billy Kane’s automatic was pressed into the small of the officer’s back. With his free hand he deftly relieved the other of a pair of handcuffs and a revolver.

“That’s all right!” said Billy Kane coolly. “Now, Barloff, stick your right hand out behind you!” He slipped one of the steel cuffs over the Russian’s wrist. “Now you, officer! No, your right hand! I know it’s customary in making an arrest to leave your right hand free, but in the circumstances I am forced to inconvenience you a little in your movements.” He snapped the other cuff shut. “Thank you! You may both turn around now!” He stepped back, hurled the officer’s revolver out through the window, and picked up the weapon whose blow, luckily for him, he had partially evaded. He had in no way been mistaken. It was the iron shaft of the crutch, and it was ingeniously fashioned with a spring catch that obviously fitted into a socket in the now missing armpiece of the crutch. It served him now as a support. He leaned upon it, using it as a cane, as he swayed a little on his feet. “I can only spare a moment,” he said engagingly to the officer; “but possibly I can make that moment well worth your while. We’ll talk quickly, if you please. I imagine that you were on your beat out there on the street when Barloff here found you. Am I right?”

“Where else would I be?” said the officer gruffly.

“That’s what I wanted to make sure of,” returned Billy Kane pleasantly. “And that’s why I want to get through here in a hurry—before your reinforcements arrive. What story did this man tell you?”

“Say,” said the officer shortly, “you’ve got your nerve with you! But you can’t get away with it! I tell you, I know you! You might as well take that mask off. You’re the Wop.”
