Of course this was a falsehood, but it would have been idle to expect the truth from one like Julius, under such circumstances. He knew Jack well enough to understand that he was quite capable of carrying out his threat, and it decided him, when the two went out, to go out himself and not to return. They might find out that he had been dealing falsely with them, and if so his life was in danger. It was yet early, and he decided to go out at once, as he usually did, for it was not very agreeable to pass an entire evening in the miserable tenement rooms. "Where are you going?" asked Marlowe, as he lifted the latch of the door. "I'm goin' out. I haven't had any supper." "You can do without supper to-night, eh, Jack?" "Yes, he can do without supper to-night." "Why? What's up?" demanded the boy. "Never mind what's up," answered Marlowe. "You ain't goin' out to-night." "I'm hungry." "We'll bring you some supper. We're goin' out ourselves." "You never kept me in before," said Julius, who felt that it was best to show surprise at the action of the confederates, though it did not surprise him. "That's neither here nor there. You ain't goin' out to-night." "All right," said Julius, "if you say so; only bring a feller some grub." "We'll bring you some," said Jack, who was not as fully convinced as his comrade of Julius' treachery. They left the room, carefully locking the door behind them. Julius sat down on the bed, and began to review the situation. Evidently he was to be locked up in the room through the night, while Jack and Marlowe were robbing the house on Madison avenue. In all probability they would be arrested, and prevented from returning. But suppose one or both escaped from the trap in which they were expected to fall. If their suspicions of his fidelity were aroused now they would be confirmed by the discovery of the police. Knowing the desperate character of both, Julius reflected with a shudder that his life would possibly be sacrificed. It would not do for him to remain here. He must escape by some means. But how? This was a difficult question to answer. The room was on the third floor, with a solitary window looking out into a small, dirty court. It was too high up to jump with safety, and there was nothing in the room by which he could descend. He was still considering this question an hour later, when the two returned. Jack had in his hand a couple of apples. "There," said he, tossing them to Julius. "That'll do you till mornin'." "Thank you," said Julius.
