Back in the church basement in Norrsbruck, Sweden, Rudy yells, and drops a cigarette on the floor, having allowed it to burn down to his fingers, like a slow fuse, while relating this story. He puts his hand to his mouth, sucks on the finger briefly, then remembers his manners and composes himself. "Göring knew a surprising amount about cryptology, and was aware of my work on the Enigma. He didn’t trust the machine. He told me that he wanted me to come up with the very best cryptosystem in the world, one that could never be broken—he wanted to communicate (he said) with U-boats at sea and with installations in Manila and Tokyo. And so, I came up with such a system."
