They have never existed any more than your Victorian detective friend. But the unconscious racial mind has reached "The North American government has to have this secret, Kevin," the girl said. "You can't let it fall into the hands of the Martians." "Fifteen cents a bed," he said mechanically. Andre did not deny that he wanted it to fall into his hands. The tubercular clerk looked up from the gaudy comics sections of one of "Fifteen cents a bed," he played it back for me. those little tabloids that have the funnies a week in advance. Miss Casey did her duty and tried to stop me with a judo hold, but I since we ain't full up. In ad don't think her heart was in it, because I reversed and broke it. I kicked the thing weren't now. Miss Casey leaned against my dirty chest and cried into it. I didn't mind her touching me. "I'm glad," she said. Andre flowed out of the doorway with a sigh. Of relief? I would never know. I supposed I had destroyed direction or love, but I would never know for sure. I thought I could kick the habit—perhaps with Miss Casey's help—but I wasn't really confident. scare me.

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." She was younger than I was, so I didn't have to call her that. "A little more for food, if you could spare it." I hadn't eaten in a day and a half, but I didn't care much. "I'll buy you a dinner," she said carefully, "provided I can go with you and see for myself that you actually eat it." I felt my face flushing red. "You wouldn't want to be seen with a bum like me, ma'am." "I'll be seen with you if you really want to eat." I was a caffeine addict. 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 human. I was a , of course, not an alien hour for the rest of my life. glass of milk. I didn't want to black out on coffee with Doc waiting for me. "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. "It's Miss Casey—Vivian Casey," she corrected. She was a 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 girl that my name was ... Kevin O'Malley. Abruptly I realized that that was my name. "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 "Happy to, miss," I mumbled.

The world disoriented itself and I was on the floor of the somber diner and Miss Vivian Casey was out of sight and scent. "She didn't," he stammered. "Why do you think I was trying to get that bill out of your hand?" 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 time from which he comes." The surprise stung. "How did you know?" I asked. He gestured with a pale hand.

She inclined the lethal silver toy. "Let me see those papers, Kevin." I handed her the doctor's manuscript. Her breath escaped slowly and loudly. "It's all right. It's all right. this myself." Doc was lying on the cot, half his face twisted into horror. "Don't move, Kevin," she said. "I'll have to shoot you—maybe not to kill, but painfully." I watched her face flash blue, red, blue and knew she meant it. But I "I just want a drink of coffee from that container on the chair," I told her. She shook her head. "I don't know what you think it does to you." It was getting hard for me to think. "Who are you?" I had to help Doc. I had to have some coffee.

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.

Martians were supposed to be against the destruction of any life-form, I had read someplace. I doubted it, but it was worth a try. "Kevin," Andre said, "why don't you take a bath?" The Martian weapon staggered me again. I tried to say something. I tried to explain that I was so dirty that I could never get clean no matter how often I bathed. No words formed.
