I scooped up my change and walked out the door. There was no one on the sidewalk, only in the doorways. * * * * * First I opened the door on an amber world, then an azure one. Neon light was coming from the chickenwire border of the room, from a window somewhere beyond. The wino on one side of the room was singing and the one on the other side was praying, same as before. Only they had changed around--prayer came from the left, song from the right. Doc sat on the floor in the half-darkness and he had made a _thing_. My heart hammered at my lungs. I _knew_ this last time had been different. Whatever it was was getting closer. This was the first time Doc had ever made anything. It didn't look like much, but it was a start. He had broken the light bulb and used the filament and screw bottom. His strong hands had unraveled some of the bed "springs"--metal webbing--and fashioned them to his needs. My orb-point pen had dissolved under his touch. All of them, useless parts, were made into a meaningful whole. I knew the thing had meaning, but when I tried to follow its design, I became lost. I put the paper container of warm coffee and the greasy bag of hamburgers on the wooden chair, hoping the odor wouldn't bring any hungry rats out of the walls. I knelt beside Doc. "An order, my boy, an order," he whispered. I didn't know what he meant. Was he suddenly trying to give me orders? He held something out to me. It was my notebook. He had used my pen, before dismantling it, to write something. I tilted the notebook against the neon light, now red wine, now fresh grape. I read it. "Concentrate," Doc said hoarsely. "Concentrate...." I wondered what the words meant. Wondering takes a kind of concentration. The words "First Edition" were what I was thinking about most. * * * * * The heavy-set man in the ornate armchair was saying, "The bullet struck me as I was pulling on my boot...." I was kneeling on the floor of a Victorian living room. I'm quite familiar with Earth history and I recognized the period immediately. Then I realized what I had been trying to get from Doc all these months--time travel. A thin, sickly man was sprawled in the other chair in a rumpled dressing gown. My eyes held to his face, his pinpoint pupils and whitened nose. He was a condemned snowbird! If there was anything I hated or held in more contempt than tourists or Martians, it was a snowbird. "My clients have occasioned singular methods of entry into these rooms," the thin man remarked, "but never before have they used instantaneous materialization." The heavier man was half choking, half laughing. "I say--I say, I would like to see you explain this, my dear fellow."
