Then he put the roof back on the little dog-house, knocked the pins back into position, stood erect, and surveyed his work with satisfaction. If Irina's father, old Dekanosov, was right, the people of the Atomnii Gorod should have plenty on their minds by summertime. The Atomic City would be busy trying to survive instead of thinking up weapons to drop on a lot of poor harmless Aleuts and Irishmen, not to mention Americans in general.

Time was getting mighty short. What should he do with the tools?

"The model Socialist worker," said Dugan to himself in Russian, "always takes good care of his tools. He realizes that the Supreme Genius, Stalin, expects the monkey wrenches to be kept out of the pigsty and the electric drills to be removed from the latrine."

He climbed back down to the entrance of Number Eighteen.

Perhaps he could come out on the other side of the mountain — or perhaps he could raise a little Cain.

"Sasha who?"
