The Peace Machine

Also published as Ground Zero Man. Hutchman was an ordinary man, doing his job, devising rocketry guidance systems. Life held its satisfactions and its frustrations. He had no spectacular ambitions. Then one day, Hutchman discovered that he could destroy the world--or save it, and destroy himself. There was no other way. But the masters of the earth didn't want it saved Hutchman's way. They wanted Hutchman destroyed along with his doomsday device. And so the chase was on. Hutchman had succeeded in one thing, at least--he had brought about unity among the world's powers. They all wanted him dead!
