Over the past fifty years, Nigel West has been involved in almost every espionage-related investigation, breakthrough or revelation that you can think of. His molehunts have led to the unmasking of spies within MI5, MI6 and the CIA and the identification of numerous others – some of whom were crucial to the Allied victory in the Second World War and would have died without any public recognition if not for him.

His first encounter with the intelligence community was a lecture given at his school by John le Carré, the guest of a Benedictine monk who had recently retired from MI6. Later, West worked as a researcher for SOE agent Ronnie Seth, who was sentenced to death by the Nazis after being captured during Operation blunderhead, and exposed two of the Cambridge spies recruited by Anthony Blunt. For the fortieth anniversary of the D-Day landings, West traced the double agent codenamed garbo and brought him to London so he could be decorated at Buckingham Palace.

As action-packed as the lives of the spies he has written about, this is the story of the most enthralling and significant post-war intelligence revelations as told by Britain's most authoritative writer on espionage and the secret services.
