About the book: 2011 / Western experts consider Kim Philby (1912–1988) the most famous of the Soviet intelligence officers. A British aristocrat, a Cambridge graduate, in 1934 he threw in his lot with Soviet intelligence and, on its instructions, entered the service of SIS, the British intelligence service. The career that the Soviet intelligence officer made in the ranks of this special service is amazing: in 1944 he headed the department involved in the fight against Soviet intelligence on British territory, and in 1949–1951 he headed the SIS-CIA liaison mission in Washington. As a result, according to one veteran of American intelligence, “all the extremely extensive efforts of Western intelligence in the period from 1944 to 1951 were ineffective. It would be better if we did nothing at all.” Philby was even one of the candidates for the post of head of SIS. The study of intelligence historian Nikolai Dolgopolov, known to readers from the book of the ZhZL series “Abel - Fischer,” not only reveals a number of little-known pages in the life of the legendary intelligence officer after his flight in 1963 from Beirut to Moscow, but also tells in detail about the entire “Cambridge Five”, which included Kim Philby. Especially for this publication, the Foreign Intelligence Service provided a number of unique declassified documents that had not previously been published..
