State Department Counterintelligence reveals an insider’s account of leaks, spies, and lies and the bureaucratic machinations that accompany them and adversely affect national security. Robert Booth tells the story of his pivotal role in three multiple year counterespionage and numerous unauthorized disclosure investigations including Fidel Castro’s most damaging US citizen spy. “He operated undetected and with impunity for decades before we discovered him. We had been hunting him for years. And now he was about to escape.” With the narrative style of a thriller, Booth lures readers into the real world of counterintelligence.
