Baron Otto von Wächter, a lawyer, husband, and father, was also a senior SS officer and war criminal, indicted for the murder of more than a hundred thousand Poles and Jews. Although he was given a new identity and life via "the Ratline" to Argentina, the escape route taken by thousands of other Nazis, Wächter and his plan were cut short by his mysterious, shocking death in Rome.

In the midst of the burgeoning Cold War, was he being recruited by the Americans or by the Soviets--or perhaps both? Or was he poisoned by one side or the other, as his son believes--or by both? With the cooperation of Wächter's son Horst, who believes his father to have been "a good man," award-winning author Philippe Sands draws on a trove of family correspondence to piece together Wächter's extraordinary life before and during the war, his years evading justice, and his sudden, puzzling death. A riveting work of history, The Ratline is part historical detective story, part love story, part family memoir, and part Cold War espionage thriller.
