"I know you find it hard to believe, but I don't. There isn't a man here on Mars who knows the whole story, either—and certainly not on Earth. We know enough to keep everything in operation. And we know it's important, all of it, everything we do."

"You mentioned a need for some men elsewhere. Where?"

"Surely you can tell me something more than—"

"Absolutely not. It isn't that I don't want to. I can't. I don't know."

"Well, one more question I'd like you to answer."

The psychiatrist lit a cigarette, grinned. "Say, who is interviewing whom?"

"This one I think you can tackle. I have a brother, Jason Temple. Embarked on the Nowhere Journey five years ago. I wonder—"

"So that's the one factor in your psychograph we couldn't figure out—anxiety over your brother."

"I doubt it," shrugged Temple. "More likely my fiancee."
