A Spy among friends

Kim Philby was the greatest spy in history---a brilliant and charming man who rose to head Britain's counterintelligence against the Soviet Union during the height of the Cold War, while also secretly working for the enemy. Nicholas Elliott, Philby's best friend and fellow officer in MI6, had no trouble trading confidences with Philby as the two had gone to the same schools and belonged to the same exclusive clubs. But Philby was betraying his British friend as well as an American one--James Jesus Angleton, the head of the CIA's counterintelligence. Every word of Elliott's and Angleton's unwitting disclosures helped Philby sink almost every great Anglo-American spy operation for twenty years, leading countless operatives to their doom.
