Kim Philby was recruited by the Russians in the early 1930s.
He entered the British Secret Service in 1939 and remained a double agent until 1962, when he escaped to the Soviet Union.
His orders, he said, were to penetrate British Intelligence and “it did not matter how long I took to do the job.”
Kim Philby’s real name was Harold Adrian Russell Philby. He was nicknamed “Kim” after Rudyard Kipling’s Indian boy-hero.
