"He became a book finder. He got rare editions of books and magazines for his clients in absolutely mint condition. That was all right--until he started obtaining books that _did not exist_." * * * * * I didn't know what all that was supposed to mean. I got to the chair, snatched up the coffee container, tore it open and gulped down the soothing liquid. I turned toward her and threw the rest of the coffee into her face. The coffee splashed out over her platinum hair and powder-blue dress that looked white when the neon was azure, purple when it was amber. The coffee stained and soiled and ruined, and I was fiercely glad, unreasonably happy. I tore the gun away from her by the short barrel, not letting my filthy hands touch her scrubbed pink ones. I pointed the gun generally at her and backed around the _thing_ on the floor to the cot. Doc had a pulse, but it was irregular. I checked for a fever and there wasn't one. After that, I didn't know what to do. I looked up finally and saw a Martian in or about the doorway. "Call me Andre," the Martian said. "A common name but foreign. It should serve as a point of reference." I had always wondered how a thing like a Martian could talk. Sometimes I wondered if they really could. "You won't need the gun," Andre said conversationally. "I'll keep it, thanks. What do _you_ want?" "I'll begin as Miss Casey did--by telling you things. Hundreds of people disappeared from North America a few months ago." "They always do," I told him. "They ceased to exist--as human beings--shortly after they received a 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. "Use one of those sneaky Martian weapons again," I warned him, "and I'll kill the girl." 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. "But, Kevin," Andre said, "you aren't _that_ dirty." * * * * * The blow shook the gun from my fingers. It almost fell into the _thing_ on the floor, but at the last moment seemed to change direction and miss it. I knew something. "I don't wash because I drink coffee." "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 was knocked to my knees.
