Jim Prideaux and Bill Roach are both new to the English preparatory school of Thursgood’s in Devon. Prideaux is a mysterious character with a crooked back who has taken a temporary appointment, while Roach is a lonely student who is gratified when Prideaux praises his powers of observation.
In London, George Smiley was until recently an officer in the British Secret Intelligence Service known to its members as the Circus. Smiley arrives home one evening to find an old associate, Peter Guillam, waiting for him. Guillam drives Smiley to the residence of Circus adviser and overseer Oliver Lacon in order to hear a story from field officer Ricki Tarr. It seems that Tarr has deserted his post in Hong Kong and secretly made his way back to England after becoming involved with the wife of a Soviet trade delegate.

After being shot in the back, Prideaux was taken to the Soviet Union for interrogation. He was released only through the efforts of his old friend and colleague (and perhaps one-time lover) Bill Haydon. In the wake of the disaster, Percy Alleline became head of the Circus, his position bolstered by a new, steady flow of seemingly valuable intelligence (code-named Witchcraft) about the Soviet bloc from a mysterious source (code-named Merlin). Haydon emerged as Alleline’s deputy, and about the same time he began an affair with Smiley’s chronically unfaithful wife Ann.
Tarr’s story makes it clear that Control was right about the mole, and Lacon authorizes Smiley to identify him. Smiley secures a safe house where he can...
