"It's all right to drink coffee, isn't it?" he asked. "Of course," I said, and added absurdly, "That's why I don't wash." "You mean," Andre said slowly, ploddingly, "that if you bathed, you would be admitting that drinking coffee was in the same class as any other solitary vice that makes people wash frequently." I looked at that which he had made. I wondered where he had gone, in "The rest is simple," Andre said. "Doc O'Malley bought up all the stock in a certain ancient metaphysical order and started supplying members with certain books. Can you imagine the effect of the Book of Dyzan or the Book of Thoth or the Seven Cryptical Books of Hsan or the back into time and created them. And that unconscious mind, deeper than psychology terms the subconscious, has always known about the powers of ESP, telepathy, telekinesis, precognition. Through these books, the human race can tell itself how to achieve a state of pure logic, fall into anyone's hands. I remembered that all the copies of the books had disappeared with their readers now. There must not be any more, I knew. that these words were what I had been waiting for. They told everything I needed I listened to him for a moment, then tested and tasted the craving that The most wonderful thing about her was her perfume. Then I realized it wasn't perfume, only the scent of soap. Finally, I knew it wasn't that. cup of coffee." I knew where I could get it for three cents, maybe two and a half. I felt her looking at me. She spoke in an educated voice, one she used, perhaps, as a teacher or supervising telephone operator. "Do you want it for coffee, or to apply, or a glass or hypo of something else?" I cringed and whined. She would expect it of me. I suddenly realized that anybody as clean as she was had to be a tourist here. I hate tourists. "Just coffee, ma'am."

"I'll buy you a dinner," she said carefully, "provided I can go with you and see for myself that you actually eat it." pale, grayish brown and steaming faintly. I picked it up in both hands to feel its warmth. Out of the corner of my eye, I could see the woman sitting on the stool with a few drops left in them. They have a little caffeine in them—not enough, never enough, but better than nothing. "Now what do you want to eat?" the woman asked. I didn't look at her. She didn't know. She thought I was a human—an Earth "Hamburger," I said. "Well done." I knew that would probably be all I didn't look at the woman. I couldn't. But I kept remembering how clean she looked and I was aware of how clean she smelled. I was so "Could I have a few to take with me, miss?" I pleaded. She smiled. I caught that out of the edge of my vision, but mostly I just felt it. said. "I'm not an old-maid schoolteacher, you know." That probably meant she was a schoolteacher, though. "No, miss," I said. schoolteacher, all right. No other girl would introduce herself as Miss Last Name. Then there was something in her voice.... "What's your name?" she said to me. I choked a little on a bite of stale bun. I . Everybody has a name, and I knew if I went off somewhere quiet and thought about it, mine would come to me. Meanwhile, I would tell the "Kevin," I told her. "John Kevin." "Mister Kevin," she said, her words dancing with bright absurdity like waterhose mist on a summer afternoon, "I wonder if you could help me "What do you think of this?"

"Why do you think I was trying to get that 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 "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, I wondered what the words meant. Wondering takes a kind of concentration. The words "First Edition" were what I was thinking about most. this unemployed, former professional man who has gone through a serious illness and is suffering a more serious addiction to tell me the place and from which he comes." The surprise stung. "How did you know?" I asked. He gestured with a pale hand. "To maintain a logical approach, I must clearly. Time travel is a familiar folk legend and I have been reading an article by the entertaining Mr. Wells. Perhaps he will expand it into one of his novels of scientific romance." I knew who these two men were, with a tormenting doubt. "But the other—" creations." The doctor flushed darkly. "You give my literary agent too much credit for the addition of professional polish to my works." The other man was filling a large, curved pipe from something that There was no theory or practice of time travel. I told them all I had ever heard theorized from Hindu yoga through Extra-sensory Perception to Relativity and the positron and negatron. "Interesting."

I thought of Cleopatra and Helen of Troy and wondered if they would be the goddesses of love that people imagined or the scrawny, big-nosed redhead and fading old woman of scholarship. Then I noticed the detective's hand that had been resting idly on a round brass weight of a snowbird. After a time, I asked the doctor a question. "Why, yes. I'm flattered. This is the first manuscript. Considering my professional handwriting, I recopied it more laboriously." She inclined the lethal silver toy. "Let me see those papers, Kevin."

"I don't know what you think it does to you." It was getting hard for me to think. "Who are you?" secret and he wanted to make money with it. He was an idealist—he had his crusades. How can you make money with time travel?" I didn't know whether she was asking me, but I didn't know. All I knew was that I had to help Doc and get some coffee. "It takes money—money Doc didn't have—to make money," Miss Casey said, "even if you know what horse will come in and what stock will me. He was lying so still with the left side of his face so twisted. I needed some coffee. "He became a book finder.

"I'll begin as Miss Casey did—by telling you things. Hundreds of book from Doc," the Martian said. Something seemed to strike me in the back of the neck. I staggered, but managed to hold onto the gun and stand up.
