your coming look casual, Frank." "Why the devil should I?" I told her. "Everyone in the Station knows how I chase you." She didn't object when I kissed her. I liked the cool firmness of her lips, and the warm firmness of her body in my arms, and the way her disorderly lock of dull-blond hair fell across her forehead. She wasn't pretty. Her mouth was too wide and her face had a little too much strength. No, she wasn't pretty—but she was beautiful. She pushed me away. "I'm getting to like that a little too much, Frank." "I wish you'd take me seriously," I complained. She laughed. "Be reasonable! I'm twenty-nine years old to your twenty-seven, I'm a very plain girl, and we don't know each other at all. It's just propinquity." I was annoyed because she always fended me off that way. But before I could argue, we heard a step on the stair. It was Varez who came up into the lookout. He smiled at us in his quiet way. He was a dark, soft-spoken young Costa Rican whom we all liked. "Just the man I want to see," I said. "I have an emotional problem. It's Marie." "What can I do about that, Drummond?" he countered. Marie laughed. "Probably Frank wants you to order me to spend a week-end with him, when we return to Earth." "You French all have evil minds," I told her. And then asked Varez, "Tell her she has to marry me." Varez laughed softly. "Transuranic Station is like heaven in only one way—there is no giving in marriage. I can't help you, Drummond." It struck me suddenly that he looked tired and depressed. "What about Nils?" I asked. "Is he all right now?" "I don't know," murmured the psychologist. He peered out of the window at the terminator creeping like a tide of darkness across the ghastly lunar plain. In the Earthshine, distant craters fanged the star-specked sky. "Can you tell us what Andersen meant by his talk in the lab?" Marie asked him soberly.
