And es also a baby sitter for their children, incidentally, and would take teller's wife on e picnics. They don't drive her where she needed to go with his car. So ewas ingratiated with edward teller and his family. Edward

teller a highly talented physicist obsessed with the idea of the hydrogen bomb. It's not the kind of bomb that's being built at los alamos, but it is an idea that in time, the americans, brits and russ ans, we'll all want to know a whole lot more about.

Klaus fukes was a very good friend and collaborator of teller's, so he no doubt knew a lot about the hydrogen bomb. Fukes

is once again, ahead of the game, but the boundary between friend and exploitation is blurred and murky. He understands that to be a good spy, he needs to build intimacy and trust. You

not only contribute something professionally as a scientist, but also you must be accepted as a human being. And to cultivate your friendships, a human being does not live in he needs to integate himself into the environment, and use that too, in order to win the appropriate recognition. In the beginning, i probably did it subconsciously, later, partly consciously, perhaps also with a bit of arrogance that i was a bit smug about my that i knew that i had the personal relationships under my control. You have to be very cautious. I am one of those people who does not make contacts easily. But when they do, then the contact is very close. And then you

are some times confronted with situations, situations over which fooks has no control. He isn't aware of it. But within the friendships fookes is forming are the seeds of future confrontations. As fookes is ingratiating himself with his colleagues on picnics and in laboratory, the overule boss of the atomic bomb programme, general groves, is trying to enforce a strict security regime. He is a highly competent engineer and manager, but first and foremost, he is a military man. Secrecy and chain of command are in his blood. So he to compartmentalize and isolate each team. But science doesn't work like that. Minds like these can't be kept in a box. They question collaborate and dispute their way to the answers. The scientific director, j robert oppenheimer, pushes back, and ultimate wins the day they

had to talk to each other.
