The Karla Trilogy: Tinker, Tailor, Soldier, Spy; The Honourable Schoolboy; Smiley's People

Three books focusing on George Smiley, an aging British spymaster at the forefront of global espionage. Tinker Tailor Soldier Spy: George Smiley, who is a troubled man of infinite compassion, is also a single-mindedly ruthless adversary as a spy. The scene which he enters is a Cold War landscape of moles and lamplighters, scalp-hunters and pavement artists, where men are turned, burned or bought for stock. Smiley's mission is to catch a Moscow Centre mole burrowed thirty years deep into the Circus itself.; The Honourable Schoolboy: It is a beleaguered and betrayed Secret Service that has been put in the care of George Smiley. A mole has been uncovered at the organisation's highest levels - and its agents across the world put in grave danger. But untangling the traitor's web gives Smiley a chance to attack his Russian counterpart, Karla.; Smiley's People: The murdered man had been an agent - once, long ago. But George Smiley's superiors at the Secret Service want to see the crime buried, not solved. Smiley will not leave it at that, not when it might lead him all the way to Karla, the elusive Soviet spymaster."
