“It's the Pug and Pinkie Bonn!” he jerked out angrily. “They're in the Pug's room. Pinkie went back there after telephonin'. They've nosed out something they want to put through. The fools! And after last night nearly havin' finished everything! I told 'em--you heard me--that everybody's to keep under cover now. But they think they've got a soft thing, and they say they're goin' to it. I've got to put a crimp in it, and you've got to help me. Y'understand, Nan?” “Yes,” she said mechanically. Her mind was working swiftly. The night, after all, perhaps, was not to be so much of a failure! To get into intimate touch with all the members of the clique was equally one of her objects, and, failing Danglar himself to-night, here was an “open sesame” to the re-treat of two of the others. She would never have a better chance, or one in which risk and danger, under the chaperonage, as it were, of Shluker here, were, if not entirely eliminated, at least reduced to an apparently negligible minimum. Yes; she would go. To refuse was to turn her back on her own proposed line of action, and on the decision which she had made herself. XII. CROOKS Vs. CROOKS It was not far. Shluker, hastening along, still muttering to himself, turned into a cross street some two blocks away, and from there again into a lane; and, a moment later, led the way through a small door in the fence that hung, battered and half open, on sagging and broken hinges. Rhoda Gray's eyes traveled sharply around her in all directions. It was still light enough to see fairly well, and she might at some future time find the bearings she took now to be of inestimable worth. Not that there was much to remark! They crossed a diminutive and disgustingly dirty backyard, whose sole reason for existence seemed to be that of a receptacle for old tin cans, and were confronted by the rear of what appeared to be a four-story tenement. There was a back door here, and, on the right of the door, fronting the yard, a single window that was some four or five feet from the level of the ground. Shluker, without hesitation, opened the back door, shut it behind them, led the way along a black, unlighted hall, and halting before a door well toward the front of the building, knocked softly upon it--giving two raps, a single rap, and then two more in quick succession. There was no answer. He knocked again in precisely the same manner, and then a footstep sounded from within, and the door was flung open. “Fools!” growled Shluker in greeting, as they stepped inside and the door was closed again. “A pair of brainless fools!” There were two men there. They paid Shluker scant attention. They both grinned at Rhoda Gray through the murky light supplied by a wheezy and wholly inadequate gas-jet. “Hello, Nan!” gibed the smaller of the two. “Who let you out?” “Aw, forget it!” croaked Rhoda Gray. Shluker took up the cudgels.
