Donald Maclean was a star diplomat, an establishment insider and a keeper of some of the West's greatest secrets. He was also a Russian spy... Codenamed 'Orphan' by his Russian recruiter, Maclean was Britain's most gifted traitor. But as he leaked huge amounts of top-secret intelligence, an international code-breaking operation was rapidly closing in on him. Moments before he was unmasked, Maclean escaped to Moscow. Drawing on a wealth of previously classified material, A Spy Named Orphan now tells this story for the first time in full, revealing the character and devastating impact of perhaps the most dangerous Soviet agent of the twentieth century. 'Superb' William Boyd 'Fascinating... An exceptional story of espionage and betrayal, thrillingly told' Philippe Sands 'A cracking story... Impressively researched' Sunday Times 'Philipps makes the story and the slow uncovering of Maclean's treachery a gripping narrative' Alan Bennett
