An hour later, I sagged in a grimy coach seat and studied Foster, sitting across from me--a middle-aged nut with the face of a young kid and a mind like a blank slate. I had no choice but to drag him with me; my only chance was to stick close and hope he got back enough of his memory to get me off the hook. It was time for me to be figuring my next move. I thought about the fifty thousand dollars I had left behind in the car, and groaned. Foster looked concerned. "Are you in pain?" he said. "And how I'm in pain," I said. "Before I met you I was a homeless bum, broke and hungry. Now I can add a couple more items: the cops are after me, and I've got a mental case to nursemaid." "What law have you broken?" Foster said. "None, damn it," I barked. "As a crook, I'm a washout. I've planned three larcenies in the last twelve hours, and flunked out on all of them. And now I'm wanted for murder." "Whom did you kill?" Foster enquired courteously. I leaned across so I could snarl in his face: "You!" Then, "Get this through your head, Foster. The only crime I'm guilty of is stupidity. I listened to your crazy story; because of you I'm in a mess I'll never get straightened out." I leaned back. "And then there's the question of old men that take a nap and wake up in their late teens; we'll go into that later, after I've had my nervous breakdown." "I'm sorry if I've been the cause of difficulty," Foster said. "I wish that I could recall the things you've spoken of. Is there anything I can do to assist you now?" "And you were the one who wanted help," I said. "There is one thing; let me have the money you've got on you; we'll need it." Foster got out his wallet, after I told him where it was, and handed it to me. I looked through it; there was nothing in it with a photo or fingerprints. When Foster said he had arranged matters so that he could disappear without a trace, he hadn't been kidding. "We'll go to Miami," I said. "I know a place in the Cuban section where we can lie low, cheap. Maybe if we wait a while, you'll start remembering things." "Yes," Foster said. "That would be pleasant." * * * * * "You haven't forgotten how to talk, at least," I said. "I wonder what else you can do. Do you remember how you made all that money?" "I can remember nothing of your economic system," Foster said. He looked around. "This is a very primitive world, in many respects. It should not be difficult to amass wealth here." "I never had much luck at it," I said. "I haven't even been able to amass the price of a meal." "Food is exchanged for money?" Foster asked. "Everything is exchanged for money," I said. "Including most of the human virtues." "This is a strange world," Foster said. "It will take me a long while to become accustomed to it." "Yeah, me, too," I said. "Maybe things would be better on Mars." Foster nodded. "Perhaps," he said. "Perhaps we should go there."
