Alec Leamas has ended his time in Berlin. Or his time has ended him. The last of his Eastern agents has been killed, like the others, by the Abteilung. Back at the Circus, Leamas is put on the shelf. He turns to drunkenness and dishonesty and finally disappears from view, a seemingly broken man. But unknown to anyone except George Smiley and his master, Control, Leamas has been given his toughest mission ever. He will have to be himself but more so.

George Smiley was summoned from his dubious retirement by two seemingly unconnected events - an old woman in Paris is promised the return of a daughter she will never see, and a handover is to take place on a steamer in Hamburg.

George Smiley has become chief of the battered British Secret Service. The betrayals of a Soviet double agent have riddled the spy network, and Smiley wants revenge. He chooses his weapon: Jerry Westerby, "The Honourable Schoolboy", a passionate lover, and a seasoned, reckless secret agent. Westerby is pointed east, to Hong Kong. So begins the terrifying game.

The Berlin Wall is down, the Cold War is over, but the world's second oldest profession is very much alive. Smiley accepts an invitation to dine with the eager young men and women of the Circus' latest intake; and over coffee and brandy, by flickering firelight, he beguilingly offers them his personal thoughts on espionage past, present, and future. In doing so, he prompts one of his former Circus colleagues into a searching examination of his own eventful secret life.
