Carefully each article was replaced. He made his way down to the third and then the second floor. Through cobwebby corridors and bedchambers he searched, but found nothing further to aid his case. In the unused rooms on the first floor he found an old spinning-wheel, candle moulds and utensils used in cooking in the days when housewives cooked over an open fire. * * * * * He did not find the "secret" passageway until Mrs. Darrow came to his aid. Leading from the basement was a coal chute. This shoot was formed in a triangle with the point under a trap. It was man-high at the cellar opening and its floor was a slide for fuel. It had been in use, evidently, quite recently. At the cellar wall of this chute, Mrs. Darrow pressed what appeared to be a knot in the old timber and pushed open a door. A dank odor issued forth as the door was opened. Lees entered the passage and Mrs. Darrow returned upstairs. Following the underground passageway, Lees came onto a cave about 14 by 14 feet in size with a ceiling and walls of arched brick. It had evidently been built before the days of cement construction. A long bench and shelves with carboys and jars of chemicals were the only furnishings. Lees sounded all the walls, but found nothing further to interest him. Lees returned to town at the urgent call of "Old Perk," who had arranged with great care to keep the appointment at 50th street and Broadway, where the decoy package was to be left. He had snipers in nearby windows. He had detectives, dressed in the gay garb of the habitues of the neighborhood, patrolling the corner, and he and his own guard parked an automobile, against all traffic rule, at the curb near the rubbish can. An office boy sauntered up to the rubbish can, threw in the decoy package, and sauntered away. A second later there was a low humming sound. The decoy package fairly jumped out of the rubbish can and disappeared in thin air. The humming sound seemed to round the corner into 50th Street. Detectives followed on the jump. The humming approached an auto at the curb and the auto's self starter began to function. As the police stood near by, enough to have jumped into the auto, the whole machine, a big touring car, actually disappeared before their eyes. Consternation is a mild word when used to describe the result. * * * * * All forces set to trap the extortionists gathered in a group, and in their surprise and disappointment began discussing the queer case in loud tones. A crowd was gathering which was blocking traffic. "Old Perk" was the first to recover from his surprise. "Get the hell out of this neighborhood," he yelled to his working forces. "All of you get down to my office!" The working force dissolved and "Old Perk" drove away. At "Old Perk's" office shortly afterward a conference of the defeated forces of the law and of science was held.
