In this classic, John le Carré's third novel and the first to earn him international acclaim, he created a world unlike any previously experienced in suspense fiction. With unsurpassed knowledge culled from his years in British Intelligence, le Carré brings to light the shadowy dealings of international espionage in the tale of a British agent who longs to end his career but undertakes one final, bone-chilling assignment.
When the last agent under his command is killed and Alec Leamas is called back to London, he hopes to come in from the cold for good. His spymaster, Control, however, has other plans. Determined to bring down the head of East German Intelligence and topple his organization, Control once more sends Leamas into the fray -- this time to play the part of the dishonored spy and lure the enemy to his ultimate defeat.

Peter Guillam, staunch colleague and disciple of George Smiley of the British Secret Service, otherwise known as the Circus, is living out his old age on the family farmstead on the south coast of Brittany when a letter from his old Service summons him to London. The reason? His Cold War past has come back to claim him. Intelligence operations that were once the toast of secret London, and involved such characters as Alec Leamas, Jim Prideaux, George Smiley and Peter Guillam himself, are to be scrutinized by a generation with no memory of the Cold War and no patience with its justifications.
Interweaving past with present so that each may tell its own intense story, John le Carré has spun a single plot as ingenious and thrilling as the two predecessors on which it looks back: The Spy Who Came in from the Cold and Tinker Tailor Soldier Spy. In a story resonating with tension, humor and moral ambivalence, le Carré and his narrator Peter Guillam present the reader with a legacy of unforgettable characters old and new.
