A conversation about the most notorious spies of the Soviet era – until today, the most high-profile example of Moscow Station intervention in the UK. Phillips is the author of a new biography, A Spy Named Orphan: The Enigma of Donald Maclean. Christened ‘Orphan’ by his Russian recruiter, Maclean was the perfect spy and 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 vanished. Macintyre wrote A Spy Among Friends, a book about Kim Philby, probably the most notorious British defector and Soviet mole in history. Agent, double agent, traitor and enigma, he betrayed every secret of Allied operations to the Russians in the early years of the Cold War. His other spy books include Agent Zigzag, Operation Mincemeat and Double Cross.
