A note of terror broke into his voice. "What a fool I should have been!" he cried out. "I should never have come here! I should never have known _him_!" Even by the light of the street lamp Marco could see him begin to look almost ghastly. "The Squad could easily have half killed me," Marco added. "They could have quite killed me, if they had wanted to do it. And who would have got any good out of it? It would only have been a street-lads' row--with the police and prison at the end of it." "But because you'd lived with him," The Rat pondered, "you walked in as if you didn't mind, and just asked why we did it, and looked like a stronger chap than any of us--and different--different. I wondered what was the matter with you, you were so cool and steady. I know now. It was because you were like him. He'd taught you. He's like a wizard." "He knows things that wizards think they know, but he knows them better," Marco said. "He says they're not queer and unnatural. They're just simple laws of nature. You have to be either on one side or the other, like an army. You choose your side. You either build up or tear down. You either keep in the light where you can see, or you stand in the dark and fight everything that comes near you, because you can't see and you think it's an enemy. No, you wouldn't have been jealous if you'd been I and I'd been you." "And you're _not_?" The Rat's sharp voice was almost hollow. "You'll swear you're not?" "I'm not," said Marco. The Rat's excitement even increased a shade as he poured forth his confession. "I was afraid," he said. "I've been afraid every day since I came here. I'll tell you straight out. It seemed just natural that you and Lazarus wouldn't stand me, just as I wouldn't have stood you. It seemed just natural that you'd work together to throw me out. I knew how I should have worked myself. Marco--I said I'd tell you straight out--I'm jealous of you. I'm jealous of Lazarus. It makes me wild when I see you both knowing all about him, and fit and ready to do anything he wants done. I'm not ready and I'm not fit." "You'd do anything he wanted done, whether you were fit and ready or not," said Marco. "He knows that." "Does he? Do you think he does?" cried The Rat. "I wish he'd try me. I wish he would." Marco turned over on his bed and rose up on his elbow so that he faced The Rat on his sofa. "Let us _wait_," he said in a whisper. "Let us _wait_." There was a pause, and then The Rat whispered also. "For what?"
