In November 1942, American spymaster Allen Dulles slipped into Switzerland just before Nazi forces sealed the border. His mission: to report on the inner workings of the Third Reich. Code-named Agent 110 by the OSS, he was astounded to find a network of Germans – industrialists, students, diplomats and generals -- conspiring to overthrow Hitler and negotiate a surrender to end World War II. On back roads, in bedrooms, and high in the Alps, Dulles plotted with his ring of renegades who were risking and losing their lives. Yet Dulles was much more than a spy. At a time when the Soviet Union was an American ally, he was driven by the conviction that Moscow aimed to dominate postwar Europe and saw in the underground a chance to thwart communist ambitions. Agent 110  brings this dangerous, dark period alive with chilling tales of spies, idealists and traitors matching wits in a vicious world. Dulles himself would eventually lead the CIA during the Cold War, driven by his wartime distrust of the Soviets.
