"Yeah, so you do." Berg sighed. "So you do."
Leavetaking was tough for all concerned. They had grown fond of the quiet, bashful man—and as for him, he wondered how he'd get along among normal people. These were his sort. Karen wept openly and kissed him good-bye with a fervor that haunted his dreams afterward. Then she stumbled desolately back to her quarters. Even Berg looked glum.
He regained his cockiness on the trip home, though, and insisted on talking all the way. Lancaster, who wanted to be alone with his thoughts, was annoyed, but you don't insult a Security man.
"You understand the importance of this whole business, and why it has to be secret?" nagged Berg. "I'm not thinking of the scientific and industrial applications, but the military ones."
"Oh, sure. You can make lightning throwers if you want to. And you've overcome the fuel problem. With a few ffuts accumulators, charged from any handy power source, you can build fuelless military vehicles, which would simplify your logistics immensely. And some really deadly hand guns could be built—pistols the equivalent of a cannon, almost." Lancaster's voice was dead. "So what?"
"So plenty! Those are only a few of the applications. If you use your imagination, you can think of dozens more. And the key point is—the ffuts and the essential gadgetry using it are cheap to make in quantity, easy to handle—the perfect weapon for the citizen soldier. Or for the rebel! It isn't enough to decide the outcome of a war all by itself, but it may very well be precisely the extra element which will tip the military balance against the government. And I've already discussed what that means."
"Yes, I remember. That's your department, not mine. Just let me forget about it."
"You'd better," said Berg.
In the month after his return, Lancaster lived much as usual. He was scolded a few times for an increasing absent-mindedness and a lack of enthusiasm on the Project, but that wasn't too serious. He became more of an introvert than ever. Having some difficulty with getting to sleep, he resorted to soporifics and then, in a savage reaction, to stimulants. But outwardly there was little to show the turmoil within him.
