Five Cambridge Graduates Became Soviet Spies and Built Stalin’s Empire

The Cambridge Five did more damage to the Western Bloc than any other intelligence outfit of the Cold War. They were five Cambridge graduates who drank gin at the right clubs, moved through the right corridors of British intelligence at the height of WW2, and quietly handed Stalin the keys to post-war Europe. Kim Philby, Anthony Blunt, Donald Maclean, Guy Burgess, and John Cairncross were recruited for their sympathies to communism because they were radicalized by the wreckage of World War I and the Great Depression. They believed that Soviet communism was the only serious answer. The Five each quickly took up a place in the British government, granting them access to top-secret intelligence that they shared with the USSR, whether decrypted German intelligence obtained from Alan Turing’s Bletchley Park and the Wehrmacht’s latest troop movements, or nuclear designs fresh from Manhattan Project labs. What followed was decades of betrayal so consequential it shaped the entire postwar map of Eastern Europe. They did this not just by passing secrets, but by condemning millions of Poles, Ukrainians, Albanians, and Baltic peoples to Soviet repression when their underground resistance networks were quietly handed over to Moscow.

Today’s guest is Antonia Senior, author of Stalin's Apostles, and she explains how she pieced together a story that was designed never to be found, because moles don't leave paper trails, and the Cambridge Five made sure their communications rarely entered any correspondence at all. We see that they did more to cause the Iron Curtain to descend deep into Europe than any other intelligence group.
