This is the story of the decade-long CIA spy-hunt driven by the paranoid convictions and Cold War obsessions of two men, the legendary American spycatcher, James Jesus Angleton, and the Soviet KGB defector, Anatoly Golitsyn. They were an instrument of destruction for their victims throughout Western intelligence, and the political ramifications are still reverberating today. Convinced that the CIA and Western intelligence had been deeply penetrated by the KGB, that the West had fallen victim to Soviet disinformation, and that only he fully realized the danger, James Angleton, the powerful head of the CIA's Counterintelligence Staff, launched a hunt for alleged Soviet spies within the CIA that spread to the secret intelligence services throughout the West, including Britain, Canada, France and Norway.
