At once Caldwell's mood became deadly serious. He leaned forward and spread his elbows on the desk.

"I'll tell you where you go from here, Dr. Hunt," he said. "Out—out to the stars! We're on our way to the stars over here! It started when Danchekker's fish first crawled up out of the mud. The urge that made them do it is the same as the one that's driven you all your life. You've gone inside the atom as far as you can go; there's only one way left now—out. That's what UNSA has to offer that you can't refuse."

There was nothing Hunt could add. Two futures lay spread out before him: One led back to Metadyne, the other beckoned onward toward infinity. He was as incapable of choosing the first as his species was of returning to the depths of the sea.

"What's your side of the deal, then?" he asked after some reflection.

"You mean, what do you have that we need?"

"Yes."

"We need the way your brain works. You can think sideways. You see problems from different angles that nobody else uses. That's what I need to bust open this Charlie business. Everybody argues so much because they're making assumptions that seem obvious but that they shouldn't be making. It takes a special kind of mind to figure out what's wrong when things that anybody with common sense can see are true turn out to be not true. I think you're the guy."

The compliments made Hunt feel slightly uncomfortable. He decided to move things along. "What do you have in mind?"

"Well, the guys we have at present are top grade inside their own specialties," Caldwell replied. "Don't get me wrong, these people are good—but I'd like them to concentrate on doing the things they're best at. However, aside from all that, I need someone with an unspecialized, and therefore impartial, outlook to coordinate the findings of the specialists and integrate them into an overall picture. If you like, I need people like Danchekker to paint the pieces of the puzzle, but I need someone like you to fit the pieces together. You've been doing a bit of that, unofficially, for quite a while anyway; I'm saying, 'Let's make it official.'"

"How about the organization?" Hunt asked.

"I've thought about that. I don't want to alienate any of our senior people by subordinating them or any of their staffs to some new whiz kid. That's only good politics. Anyhow, I don't think you'd want it that way."

Hunt shook his head to show his agreement.
