"That was when I first looked at the lab analysis and took the gloomiest possible view of his chances. I didn't even know you heard me. Damn it all, Susan. Can't a doctor think out loud without giving his most competent nurse a martyr complex? What is there about him? I'm asking you. If he wasn't married I could perhaps understand it. I could at least make a stab at trying to figure it out. But you've seen his wife. A man with a wife as attractive as she is would have to be even more susceptible than I am to look twice at another woman. That's just another way of saying it couldn't happen."

"I've had two long talks with her, Roger. She loves him so much that if anything happened to him I'm afraid to think what she might do. All alone on Mars, with no close relatives or friends to turn to for help and warmth and comfort. She'd need a lot of support, because there's nothing shallow about her. She's the intense type, very deep in her emotions. I'm that way myself."

"You don't have to tell me," I could hear him saying. "You're the empathy-plus type. It's what makes a good many otherwise sensible women embrace the toughest profession on the list. Hard-boiled, unemotional women make good nurses too. But I prefer the kind of nurse you can't help being. Only ... a little moderation even in people who go all out can be a saving grace."

"But don't you see, Roger? It means I can identify with her. I know exactly how terrible the uncertainty must be for her, because if I loved a man that much and lost him I'd probably go right out and kill myself. If you want the full truth ... there's probably a little of the male-female absurdity mixed up in it too. It's an absurdity in a situation like this, where it makes no sense. But just the fact that he's a man and I'm a woman—"

"Talk like that will get you nowhere," he said. "I'm too sure of you."

There was a rustling sound and a sudden gasp and I was pretty sure I knew what it meant. He'd taken her into his arms and was kissing her. I don't know why I didn't open my eyes. I was fully awake now, aware of every movement in the room. But I just remained quiet and listened, grateful that the needles had stopped jabbing at my temples and my dizziness was practically gone.

Sometimes when you awake suddenly from a deep sleep your eyes feel glued shut, and it takes an effort just to open them. You let it ride for a moment, while you pull yourself together ... especially if it's a nightmare you've just awakened from. There's a kind of pleasure in it.

He was talking again. "I've yet to meet a woman who doesn't think that clinical self-analysis will keep a man guessing about her. But that kind of candor will get you nowhere with me, kiddo. I know you too well. Are you convinced?"

"Yes," she said, with a meekness that surprised me.

He didn't say anything for a moment, but I could hear him moving about and a metallic click, as if he were folding up his stethoscope or returning a hypodermic to its case.
