"I must go back and help him," thought Roy. "Mr. De Royster is no match for that fellow. I'd like to tackle him on my own account, though he was not cruel to me while he had me a prisoner." His determination to do this was increased when his friend leaned out of the window, and called: "Come on up, Roy! Help me!" "He's plucky to tackle that fellow alone," thought the boy from the ranch. But now he had no time for musings. He must act. As he let go the rope, his feet having touched the ground, he found himself in the not very clean yard of the tenement. About him were boxes and barrels of rubbish, decaying vegetables were on all sides, besides tin cans and heaps of refuse. Clearly the tenants in the house were not particular. Roy looked about him. The yard was surrounded by a high fence, and there were no persons in sight. To the rear was the electric light plant, and on either side, the yards of other tenement houses. Then Roy saw an alley, which, he thought, would lead to the street. Leaving his lariat dangling, he made a dash for the alley and soon found himself in front of the tenement house, where he had so recently been a prisoner. Up the stairs he went on the jump, and, as he came near the room where he had been held, he could hear the sound of a struggle. "They're fighting!" he thought. "I must help De Royster!" As he entered the apartment he saw the jewelry salesman holding Wakely by the wrists, while the man was endeavoring to get away. "Quiet now, my dear fellow!" exclaimed Mortimer De Royster. "I say, old chap, you can't get away, don't you know. I've got you, and I'm going to have you arrested." "You are, eh? I'll see about that!" exclaimed Wakely. "Let go of me!" At the same time he gave a violent wrench. "Hold on, my dear fellow," remonstrated De Royster. "You mustn't do that, don't you know." In spite of his rather slight built De Royster was proving himself almost a match for Wakely. But his strength was not of the lasting kind, while the other's was. "Let me go!" fiercely demanded Wakely. "If you don't it will be the worst for you!" At the same time he gave such a yank that he succeeded in freeing one arm. But De Royster was not going to give up so easily. He grabbed Wakely around the waist. At that moment Roy made a rush for Wakely. Just as he was about to grab him, he was thrust aside by some one from behind. Wakely turned, gave one look at the newcomer, and cried: "Quick! Tell Annister he's escaped!" Wakely had not yet observed Roy, as the boy from the ranch was back of him. Then the man who had taken Roy from the hotel succeeded in breaking the hold De Royster and Roy had on him. He dashed from the room, just as the other man, to whom he had called the warning, also ran out. Both seemed much frightened. "Hold on!" cried De Royster, as if either of the men would stop for that. "Hold on! I know you."
