"Because you're under arrest. I was after you when I happened to find the other fellow. I haven't any idea you'll try and escape, Mr. Gladwin, but a warrant is a warrant and duty's duty." "But that warrant wasn't meant for me." "No?" Kearney's eyes widened with surprise. "Was the girl running off with that crook?" he asked quickly. "No," Gladwin corrected, realizing his break. "Then you better go along with Ryan. Ryan, you take him upstairs and sit by him till I send for you." "See here," the young man began to splutter as the giant Ryan seized him and walked him on air out of the room and up the stairs. Kearney went to the folding doors and shut them. "He's in this room somewhere," muttered the detective, going to the portières that curtained the window leading out to the balcony. He was almost touching Wilson when the latter suddenly enveloped him in the portière he had wrapped around himself and hurled the big detective to the floor. As Kearney was untangling himself Wilson darted between the portières, glanced out the window and saw that a leap from the balcony would land him in the arms of three patrolmen. He shook open the window and then shrank back into the far corner of the embrasure. Kearney was on his feet again and sprang out to the balcony. "He came out this way," he yelled to the men below. "Did he jump off?" Kearney darted back into the room, looked everywhere, ran to the folding doors and flung them open. Then he looked back at the panel door, noticed that it was ajar and dived for it. "He's hiding somewhere in this black alley," he said with an oath, and disappeared. A moment later Wilson peeked out and re-entered the room. He had scarcely left his place of concealment when Officer No. 666 burst in. "Oh, there ye are, Mr. Gladwin!" said Phelan, with a lovely grin. "Yes, I'm here," nodded Wilson. "I just come back with another bunch of cops," said Phelan, "but I hear the crook got away. He's a smooth snake fer ye." "No, I think he's still in the house," laughed Wilson, "and I'd like to have you get the credit of catching him, Phelan. You go outside and report to the captain, then come back here. Maybe I can help you find him." "Thank ye, sorr," said Phelan, obeying the suggestion. "Here comes another one," breathed the thief, hearing a heavy tread and crossing the room to the big ornamental fireplace which had never known a spark or speck of soot. There was a mammoth opening in the chimney and Wilson vanished up it as Kearney plunged back into the room. As the detective entered through the panel door, Watkins in full chauffeur regalia appeared from the hallway. "Well, who sent you?" Kearney pounced on him. "I don't know," Watkins returned. "Some man--Gladwin, I think, is the name. I was sent here for a lady." "Well, you sit out in the hall and wait," snapped Kearney, who again proceeded to explore the room, muttering and cursing.
