James Jesus Angleton: even the name is an enigma, the middle name an inheritance from his Mexican mother. So was the person, a remote Anglophile who was an orchid raiser and adept fly fisherman. For more than twenty years as counterintelligence chief of the CIA, Angleton was "spycatcher for the Western world." Mangold, a BBC producer, has interviewed carefully and even-handedly and writes this fascinating story in sturdy prose. Yet the book is a commanding indictment: in spydom's wilderness of mirrors, Angleton slipped from caution to obsession. Passionately committed to the truth as revealed by one Soviet defector, Anatoly Golitsyn, he dismissed contrary evidence, stopped all else to turn the CIA upside down in his search for a KGB mole and, in the process, did grievous harm to the agency he loved.
