Leaving the chaos of postwar Germany for an uncertain future, 16-year-old Gerhardt Thamm arrived in America in 1948 with little more than his American birth certificate. With minimal command of English and little formal education, he enlisted in the Army and quickly found himself assigned to operations where his German language abilities were put to use. With the Soviet Union's emergence as a potential adversary, Thamm was recruited into the Army's clandestine services, where he operated as a secret agent in Germany, under multiple identities. This richly detailed personal narrative tells Thamm's incredible story and is supplemented by more than two dozen of the author's personal photographs and sketches.
