Not since The Diary of Anne Frank has a young voice so vividly expressed the capacity for humanity and heroism in the face of Nazi brutality.

    They had little trouble getting in. With scant scrutiny, many gained entry on their own as self-styled war "refugees," their pasts easily disguised and their war crimes soon forgotten. But some had help and protection from the U.S. government. The CIA, the FBI, and the military all put Hitler's minions to work as spies, intelligence assets, and leading scientists and engineers, whitewashing their histories. For the first time, once-secret government records and interviews tell the full story not only of the Nazi scientists brought to America, but of the German spies and con men who followed them and lived for decades as ordinary citizens. Only years after their arrival did private sleuths and government prosecutors begin trying to identify the hidden Nazis. But even then, American intelligence agencies secretly worked to protect a number of their prized spies from exposure. Today, a few Nazis still remain on our soil. Investigative reporter Eric Lichtblau, relying on a trove of newly discovered documents and scores of interviews with participants in this little-known chapter of postwar history, tells the shocking and shameful story of how America became a safe haven for Hitler's men.
