Camhorn shook his head. "We can't say how much they really knew, Gus. The theft might have been arranged as a speculative operation. There's enough loose money in large quantities around to make that quite possible."

Fry grunted. "Do you have any definite suspects?"

"A great many. Unfortunately, there seems to be at least some probability that the people involved won't turn out to be among them. However, those lists will provide an immediate starting point. They're being transferred to the IPA today."

"Thanks," Fry said sourly.

"I wouldn't do it if I didn't have to, Gus. Our Research investigators can't begin to cope with a number like that. They will cooperate with you closely, of course."

"Nobody else will," said Fry. "I've come to the conclusion that our current populations are the least cooperative people in the history of the race."

Camhorn nodded. "Naturally."

"Naturally? Why should they be? Most of them are a little short of living space—unless they're willing to put up with frontier conditions—but otherwise humanity's never had it so good. They're not repressed; they're babied along—nine-tenths of the time anyway. They do just about as they damn well please. Thirty percent of them won't turn out a stroke of honest work from the beginning of their lives to the end."

"True enough. And you've described an almost perfect setting for profound discontent. Which is being carefully maintained, by the way. We don't want humanity to go to sleep entirely just yet. Gus, how much do you know personally about Ym-400?"

"Nothing," said Fry. "Now and then some rumor about it comes to the IPA's attention. Rumors of that kind go into our files as a matter of course. I see the files."
