I got up and started pacing. Foster had already told me there was nothing to connect him with his house in Mayport; the locals there had seen enough of him to know he was pushing middle age, at least. I could kick and scream and tell them this twenty-year-old kid was Foster, but I'd never make it stick. There was no way to prove my story; they'd figure Foster was dead and that I'd killed him--and anybody who thinks you need a _corpus_ to prove murder better read his Perry Mason again. I glanced out of the window and did a double take. Two cops were standing by Foster's car. One of them went around to the back and got out a pad and took down the license number, then said something over his shoulder and started across the street. The second cop planted himself by the car, his eye on the front of the hotel. I whirled on Foster. "Get your shoes on," I croked. "Let's get the hell out of here." We went down the stairs quietly and found a back door opening on an alley. Nobody saw us go. * * * * * 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," 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 inquired 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.
