"He took to a cab," explained Tom, "and him and his partner give us a fierce chase down the avenoo. O'Halloran shot the horse, and the cab was all knocked to hell. The other fellow clawed out before we could nab him. But we got this one all right." "Hi, there, McCarthy!" shouted the sergeant to someone in the dim vast beyond. "Come and open up." He examined McAllister with a degree of interest. "Quite a swell guy!" he commented. "Them dress clothes must have been real pretty onc't." McAllister stood with soaked and rumpled hair, hatless and collarless, his coat torn and splashed, and his shirt-bosom bloody and covered with mud. He wanted to cry, for the first time in thirty-five years. "Wot's yer name?" asked the sergeant. The prisoner remained stiffly mute. He would have suffered anything rather than disclose himself. "Where do yer live?" Still no answer. The sergeant gave vent to a grim laugh. "Mum, eh?" He scribbled something in the blotter upon the desk before him. Then he raised his eyes and scrutinized McAllister's face. Suddenly he jumped to his feet. [Illustration: "Do you know who you've caught?"] "Well, of all the luck!" he exclaimed. "Do you know who you've caught? It's Fatty Welch!" IV How he had managed to live through the night that followed McAllister could never afterward understand. Locked in a cell, alone, to be sure, but with no light, he took off his dripping coat and threw himself on the wooden seat that served for a bed. It was about six inches too short. He lay there for a few moments, then got wearily to his feet and began to pace up and down the narrow cell. His legs and abdomen, which had been the recipients of so much attention, pained him severely. The occupant of the next apartment, awakened by our friend's arrival, began to show irritation. He ordered McAllister in no gentle language to abstain from exercise and go to sleep. A woman farther down the corridor commenced to moan drearily to herself. Evidently sleep had made her forget her sorrow, but now in the middle of the night it came back to her with redoubled force. Her groans racked McAllister's heart. A stir ran all along the cells--sounds of people tossing restlessly, curses, all the nameless noises of the jail. McAllister, fearful of bringing some new calamity upon his head, sat down. He had been shivering when he came in; now he reeked with perspiration. The air was fetid. The only ventilation came through the gratings of the door, and a huge stove just beyond his cell rendered the temperature almost unbearable. He began to throw off his garments one by one. Again he drew his knees to his chest and tried to sleep, but sleep was impossible. Never had McAllister in all his life known such wretchedness of body, such abject physical suffering. But his agony of mind was even more unbearable. Vague apprehensions of infectious disease floating in the nauseous air, or of possible pneumonia, unnerved and tortured him. Stretched on the floor he
