In Puppetmaster, Richard Hack separates truth from fiction to reveal the most hidden secrets of Hoover's private life and exposes previously undisclosed conduct that threatened to compromise the security of the entire nation. Based on files, documents, and over 100,000 pages of FBI memos and State Department papers, Hack rips the lid off Hoover's façade of propriety to detail a life replete with sexual indiscretions, criminal behavior, and a long-standing alliance with the Mafia.
