This first novel in LeCarre’s Karla Trilogy is definitely worth a read, especially as it is being remade into a movie later this year. Set at the height of the Cold War, LeCarre’s hero, the British Secret Service Agent George Smiley, is forced out of retirement and placed in charge of finding the Soviet mole within the British ranks. The excellent pacing and intrigue will keep you turning the pages until the mole is uncovered.
