"What t' hell are you doin' here?" cut in the big man as he pushed my revolver-end away and dropped his own gun into his pocket. "I've been trailin' these guys for five weeks—and I want to know why you're queerin' my job!"

Creegan, who had been feeling his front teeth between an investigatory thumb and forefinger, blinked up at the big man. Then he turned angrily on me.

"Put down that gun!" he howled. He took a deep breath. Then he laughed, mirthlessly, disgustedly. "You can't shoot him!"

"Why can't I?"

"He's a stool pigeon! A singed cat!"

"And what's a stool pigeon?" I demanded. "And what's a singed cat?"

Creegan laughed for the second time as he wiped his mouth with the back of his hand.

"He's a Headquarters gink who stays on the fence, and tries to hunt with the hounds the same time he's runnin' with the hares—and gener'ly goes round queerin' an honest officer's work. And I guess he's queered ours. So about the only thing for us to do, 's far as I can see, is for us to crawl off home and go to bed!"
