A big-game hunter from a wealthy family, Gertrude "Gertie" Legendre lived a charmed life in Jazz Age America. But when the Japanese attacked Pearl Harbor, Legendre, by then married and a mother of two, joined the OSS, the wartime spy organization that preceded the CIA. In A Guest of the Reich, Peter Finn tells the gripping story of how in 1944, while on leave in liberated Paris, Legendre was captured by the Germans after accidentally crossing the front lines. Subjected to repeated interrogations, including by the Gestapo, she entered a daring game of lies with her captors. The Nazis treated her as a "special prisoner" of the SS and moved her from city to city throughout Germany, where she witnessed the collapse of Hitler's Reich as no other American did, before escaping into Switzerland. A Guest of the Reich is a propulsive account of a little-known chapter in the history of World War II, as well as a fascinating portrait of an extraordinary woman.
