Memoir reveals regret of Soviet spy Anthony Blunt - Yahoo! News Anthony Blunt — English gentleman, art adviser to Queen Elizabeth II and Soviet spy — felt the decision to give British secrets to the Kremlin was "the biggest mistake of my life." Blunt wrote of his remorse in a 30,000-word memoir completed shortly before his death in 1983 and released Thursday by the British Library. It was given to the library in 1984 on condition it not be made public for 25 years. Blunt was the infamous "fourth man" in a ring of upper-class Britons who spied for the Soviet Union. He, Guy Burgess, Kim Philby and Donald Maclean attended Cambridge University in the 1930s and — fired by opposition to the spread of fascism across Europe — were drawn into espionage. The document reveals few new details of Blunt's career as a spy, but recounts how he was recruited at Cambridge by the charismatic Burgess. Blunt wrote that he believed, "naively," that the story would never be made public. However, in 1979 Prime Minister Margaret Thatcher publicly unmasked him as a Soviet spy, and he was stripped of his knighthood. Blunt said he considered suicide but decided it would be cowardly to leave his friends and family with "the double shock of my suicide and the revelations which would have followed immediately." Blunt said that after he was exposed he took refuge in "whisky and concentrated work." The manuscript, which has been known about for years but never made public, is likely to disappoint historians because it does not contain any sensational revelations.
