Two of his subjects — the spy and the pilot — were the original seekers of weapons of mass destruction. The third, an intellectual, fluent in German, unencumbered by dependents, and researching a Ph.D. thesis on the foreign trade system of the Soviet bloc, seemed to the Stasi precisely the sort of person the CIA should have been recruiting. He was not. In over his head in the world capital of spying, he was wrongly charged with espionage and thus came to the Agency’s notice by a more roundabout route. The three men were rescued against daunting odds by fate and by their families, and then all but forgotten. Yet they laid bare the pathological mistrust that fueled the arms race for the next 30 years.  Drawing on new interviews conducted in the United States, Europe and Russia with key players in the exchange and the events leading to it, among them Frederic Pryor himself and the man who shot down Gary Powers, Bridge of Spies captures a time when the fate of the world really did depend on coded messages on microdots and brave young men in pressure suits. The exchange that frigid day at two of the most sensitive points along the Iron Curtain represented the first step back from where the superpowers had stood since the building of the Berlin Wall the previous summer – on the brink of World War III.
