"And Dr. Gomes and Dr. Murillo and Dr. Livesey left papers and plans lying around all over the place," Paula added. "If he went to Niflheim as a spy, he could have copied almost anything."
"Well, there you have it," von Schlichten said. "When Gorkrink found out that plutonium can be used for bombs, he began gathering all the information he could. And as soon as he got home, he turned it all over to Pappy Orgzild."
"That still doesn't mean that the Kee-geeks were able to do anything with it," Air-Commodore Hargreaves argued.
"I think it does," von Schlichten differed. "As soon as Orgzild would hear about the possibility of making a plutonium bomb, he'd set up an A-bomb project, and don't think of it in terms of the old First Century Manhattan Project. There would be no problem of producing fissionables--we've been scattering refined plutonium over this planet like confetti."
"Well, an A-bomb's a pretty complicated piece of mechanism, even if you have the plans for it," Kent Pickering said. "As I recall, there have to be several subcritical masses of plutonium, or U-235, or whatever, blown together by shaped charges of explosive, all of which have to be fired simultaneously. That would mean a lot of electrical fittings that I can't see these geeks making by hand."
"I can," Paula said. "Have you ever seen the work these native jewelers do? And didn't you tell me about a clockwork thing they have at the university, here, to show the apparent movements of the sun...."
"That's right," von Schlichten said. "And what they couldn't make, they could have bought from us; we've sold them a lot of electrical equipment."
"All right, they could have built an A-bomb," Buhrmann said. "But did they?"
"We assume they tried to. Gorkrink got back from Nif on the _Canberra_, three months ago," von Schlichten said. "If Orgzild decided to build an A-bomb, he wouldn't give the signal for this uprising until he either had one or knew he couldn't make one, and he wouldn't give up trying in only three months. Therefore, I think we can assume that he succeeded, and had succeeded at the time he sent Gorkrink here to get that four tons of plutonium we let him have, and, incidentally, to tell his ambassador to pass the word to have Sid Harrington poisoned according to plan."
