The man he knew as "Control" is dead, and the young Turks who forced him out now run the Circus. But George Smiley isn't quite ready for retirement – especially when a pretty, would-be defector surfaces with a shocking accusation: a Soviet mole has penetrated the highest level of British Intelligence. Relying only on his wits and a small, loyal cadre, Smiley recognises the hand of Karla – his Moscow Centre nemesis – and sets a trap to catch the traitor. Now a successsful movie released by Working Title, directed by Thomas Alfredson and starring Gary Oldman as George Smiley.
