Our take on the The Defector: The Untold Story of the KGB Agent Who Saved MI5

Richard Kerbaj's The Defector is a narrative history of Oleg Lyalin, the KGB officer whose 1971 defection to Britain exposed Soviet plans to plant fake agents inside MI5 and the CIA. Drawing on newly declassified documents and interviews with spymasters, it follows how Lyalin's revelations pushed MI5 to break with the CIA and wrecked the credibility of defector Anatoly Golitsyn and counterintelligence chief James Jesus Angleton. It suits readers of Cold War espionage history who want a documented account rather than a spy thriller. Its edge over older Angleton- and Golitsyn-centered books is the Lyalin side of the story, told at book length for the first time.

About the The Defector: The Untold Story of the KGB Agent Who Saved MI5

The Defector is a nonfiction Cold War spy history by Richard Kerbaj. It tells the story of Oleg Lyalin, a former KGB officer who defected to the West, and the secrets he revealed.

The book draws on newly declassified intelligence documents and dozens of interviews with spymasters. It covers a Soviet mission to plant fake Kremlin agents within British and American intelligence services, and the paranoia that followed.

Lyalin's defection led MI5 to rethink its relationship with the CIA. It also discredited an earlier KGB defector, Anatoly Golitsyn, and ultimately destroyed the reputation of the CIA's head of counterintelligence, James Jesus Angleton. The story involves lies, disinformation, Kremlin deception campaigns, intelligence failures by the CIA and MI5, and a tangled love life.
