Following nearly a decade of research, this account solves the mysterious death of biochemist Frank Olson, revealing the identities of his murderers in shocking detail. It offers a unique and unprecedented look into the backgrounds of many former CIA, FBI, and Federal Narcotics Bureau officials--including several who actually oversaw the CIA's mind-control programs from the 1950s to the 1970s. In retracing these programs, a frequently bizarre and always frightening world is introduced, colored, and dominated by many factors--Cold War fears, the secret relationship between the nation's drug enforcement agencies and the CIA, and the government's close collaboration with the Mafia.
