Spying on America

Leon Turrou was the FBI agent closest to the Nazi spy ring in America in the late 1930s. His leaks to the American press and the book he was allegedly writing led to him being fired from the Bureau by J. Edgar Hoover. But he did publish his book, this book, and then Hollywood made a movie of the case that starred none other than Edward G. Robinson. Turrou was one of America's original whistleblowers.
