Story in 60 Seconds

The short version

George Smiley has retired from the Circus after a disastrous operation in Czechoslovakia. New evidence of a Soviet mole brings him back to investigate senior officers who once worked beside him. With Peter Guillam's help, he examines missing files and interviews people pushed aside by the service's new leadership. The celebrated intelligence source called Witchcraft becomes suspect: information apparently arriving from Moscow may conceal British secrets traveling the other way. Smiley sets a trap at a London safe house, where professional suspicion intersects with his wife's affair and Jim Prideaux's betrayal.

Spoiler sectionEnding ExplainedShow ending detailsHide ending details

Smiley catches Bill Haydon meeting the Soviet officer Polyakov and exposes him as the mole. Haydon dies in custody before an arranged exchange; the novel strongly implies Prideaux's involvement without directly showing the killing. Smiley takes temporary charge of the damaged Circus. The investigation identifies the traitor while leaving him responsible for repairing networks that Haydon's colleagues had trusted.
