In this engrossing and deeply disturbing exposé from the bestselling author of Nuclear War: A Scenario, Annie Jacobsen tells the gripping story of a decades-long, covert project to bring Hitler's scientists and their families to the United States. In the chaos following the Second World War, the US government faced a critical decision: what to do with the great scientific minds of the Third Reich. Many were accused of war crimes, and others had stood trial at Nuremberg; one was convicted of mass murder.Nevertheless, the US government secretly decided that their knowledge of rocketry and medical advances were vital to the outcome of the Cold War. Drawing on exclusive interviews with dozens of Paperclip family members, colleagues, and interrogators, and dossiers discovered in archives across the world, Annie Jacobsen follows more than a dozen German scientists through their postwar lives and into one of the most startling, complex, nefarious, and jealously guarded government secrets of the twentieth century. ‘Chilling and riveting ... a remarkable achievement of investigative reporting and historical writing’ Boston Globe‘The most in-depth account yet of the lives of Paperclip recruits and their American counterparts’ New York Times Book Review
