More than 70 years after the Cambridge spy ring was revealed, MI6 documents suggest that it had another member
When the KGB spies Guy Burgess and Donald Maclean defected to Moscow in 1951, a frenzied media hunt began for “The Third Man” who had tipped them off.
That man was eventually identified as MI6 officer Kim Philby. The Fourth Man was the Surveyor of the Queen’s Pictures, Sir Anthony Blunt. The fifth was civil servant John Cairncross.
These were the infamous Cambridge Five. Now, more than 70 years later, declassified MI5 files suggest the spy-hunters failed to catch another agent in the Soviet espionage web. The Sixth Man may have been a woman.
