When a Russian emigre is found murdered on Hampstead Heath, Smiley is called out of retirement to exorcise some Cold War ghosts from his clandestine past. What follows is Smiley the human being at his most vulnerable and Smiley the case officer at his most brilliant; and it makes to a thrilling conclusion his career-long, serpentine battle with the enigmatic and ruthless Russian spymaster Karla.
Starring the award-winning Simon Russell Beale as Smiley, and with a distinguished cast including Anna Chancellor, Lindsay Duncan, Maggie Steed, Alex Jennings and Kenneth Cranham, this enthralling dramatisation captures every nuance of le Carre's complex and compelling novel - the final book in John le Carre's Karla trilogy.
