Oleg Gordievsky was a Russian KGB agent who, for over ten years during the Cold War, spied for the British government on behalf of MI6. The author retells the tales of Gordievsky’s engagement, espionage, and eventual extraction from the Soviet Union based on interviews with Gordievksy himself, as well as other MI6 and KGB agents.

While this book is nonfiction, it was such a gripping story that I felt like I was reading a spy thriller. The pace of this book was excellent and held my interest throughout while still proving a plethora of information and details. A great read or listen for anyone interested in history!
