Background As the tension of the
Cold War is peaking in 1973,
George Smiley, former senior official in Britain's Secret Intelligence Service (known as "the Circus" because its London office is at
Cambridge Circus), is living unhappily in forced retirement, following the failure of an operation codenamed Testify in
Czechoslovakia, which ended in the capture and torture of agent
Jim Prideaux.
Control, chief of the Circus, had suspected that one of the five senior intelligence officers at the Circus was a Soviet mole, and had assigned them code names for Prideaux to relay back to the Circus, derived from the English children's rhyme "
Tinker, Tailor":Tinker, tailor, soldier, sailor, rich man, poor man, beggarman, thief. The failure resulted in the dismissal of
Control, Smiley, and allies such as
Connie Sachs and
Jerry Westerby, and their replacement by a new guard consisting of Percy Alleline,
Toby Esterhase,
Bill Haydon, and Roy Bland. Control has since died, and Smiley's former protégé,
Peter Guillam, has been demoted to the "
scalphunters". Guillam unexpectedly approaches Smiley and takes him to the house of
Under-Secretary Oliver Lacon, the
civil servant who oversees the Circus. There, they meet Ricki Tarr, an agent recently declared
persona non grata due to suspicion that he has defected. Tarr defends himself by explaining that he was informed of a Soviet
mole at the highest level of the Circus – codenamed Gerald – by Irina, the wife of a trade delegate, while in
Hong Kong. Irina claimed that the mole, Gerald, reports to a Soviet official stationed at the
embassy in London called Polyakov. Shortly after Tarr relayed this to the Circus, Irina was forcibly returned to the Soviet Union, leading Tarr to suspect that the mole was real, and now knew his identity. Tarr went into hiding, resurfacing to contact Guillam. Lacon reasons that neither Smiley nor Guillam can be the mole, due to their respective dismissal and demotion, and so requests that Smiley investigate the presence of the mole in total secrecy to avoid another
PR scandal for both the Government and the Circus. Smiley cautiously agrees, and forms a team consisting of himself, Guillam, Tarr, and retired
Scotland Yard Inspector Mendel. Smiley is also given access to Circus documents, and begins by examining Alleline's restructuring, discovering the ousting of Jerry Westerby and Connie Sachs, as well as
slush fund payments to Jim Prideaux.
Smiley begins the hunt Smiley visits Sachs, discovering that she confronted Alleline about her discovery that Polyakov was actually a Soviet Colonel called Gregor Viktorov, but he ordered her to drop the subject. She also mentions rumours of a secret Soviet facility for training moles, and makes allusions to Prideaux and Bill Haydon's relationship being more than just
platonic friendship. Smiley examines Operation Witchcraft, an operation in which Soviet intelligence was obtained through a key source known as "Merlin", which was treated with suspicion by both Smiley and Control. Alleline obtained ministerial support to circumvent Control's authority, and his post-Testify promotion supporters Haydon, Esterhase, and Bland have sponsored it. Smiley also learns that this "Magic Circle" has obtained a
safe house somewhere in London where they obtain information from a Merlin emissary posted in London under a diplomatic cover, who – Smiley concludes – is Polyakov himself. Smiley suspects that the Circus does not realise the flow of information is going the other way, with the mole "Gerald" passing important British secrets ("gold dust") in return for low-grade Soviet material ("chicken feed"), which would make "Witchcraft" simply a cover for the mole.
Karla Smiley also discovers that the log from the night Tarr reported in from Hong Kong has been removed, and Guillam starts to suffer from paranoia as a result of their operation. Smiley tells Guillam that he suspects a Soviet intelligence officer named
Karla is linked in some way to the operation, and reveals what he knows about him. Karla is believed to have followed his father into espionage, getting his start during the
Spanish Civil War, posing as a
White Russian émigré in the forces of General
Francisco Franco, recruiting foreign, mainly German, operatives. After this, the Circus lost track of Karla, but he resurfaced during
Operation Barbarossa, directing
partisan operations behind German lines. Smiley explains his belief that somewhere in the gap between these two conflicts, Karla travelled to England and recruited Gerald. Smiley points out that Karla is fiercely loyal to both the
Soviet Union and communism, highlighting Karla's current rank despite his internment in a
gulag by the
Stalinist regime. He reveals that Karla turned down an offer from Smiley in India to defect, even though his return to the Soviet Union in 1955 was to face a likely execution, after Smiley worked with American authorities to disrupt Karla's efforts to establish a clandestine radio transmitter for agents in San Francisco. During his attempt to obtain Karla's defection, Smiley plied him with cigarettes and promises that they could get Karla's family out to the West safely. Smiley suspects that this only revealed his own weakness, his love for his unfaithful wife, Ann. Smiley offered Karla his lighter, a present from Ann, to light a cigarette, but Karla rose and left with it.
Merlin and Testify Smiley suspects a link between Merlin and the botched Operation Testify. Sam Collins, who was the duty officer that night, tells Smiley that Control ordered him to relay the report of the Czech operation only to him, but that when he did so, Control froze up, and that Bill Haydon's sudden arrival was the only reason the hierarchy did not fall apart that night. Smiley then visits Max, a
Czech operative who served as a legman for Prideaux on the operation, who tells Smiley that Prideaux gave him instructions to leave
Czechoslovakia any way he could if Prideaux did not surface at the rendezvous at the appointed time. Smiley next visits Jerry Westerby, who tells Smiley about the trip to
Prague when a young army conscript insisted that the Soviets were in the woods waiting for Prideaux a full day before he was ambushed. Finally, Smiley tracks down Prideaux, who tells him Control believed there was a mole in the Circus and had whittled it down to five men, Alleline (Tinker), Haydon (Tailor), Bland (Soldier), Esterhase (Poorman), and Smiley himself (Beggarman). Prideaux's orders were to obtain the identity from a defector in
Czech intelligence who knew. He tells Smiley he almost did not make the rendezvous with Max because he noticed he was being tailed, and that when he arrived to meet the defector, he was ambushed, taking two bullets to his right shoulder. During his captivity, both Polyakov and Karla interrogated him, focusing solely on the extent and status of Control's investigation. Prideaux suggests that the Czech defector was a plant, contrived by Karla to engineer Control's downfall through Testify's failure, all conceived to protect the mole.
Catching the mole Smiley confronts Toby Esterhase, stating that he is aware that Esterhase has been posing as a Soviet mole, with Polyakov as his handler, to provide cover for Merlin's emissary, Polyakov. Smiley compels Esterhase into revealing the location of the safe house by making him realise that not only is there a real Soviet mole embedded in the SIS, but also that Polyakov has not been "turned" to work in British interest, pretending to run the "mole" Esterhase, and in fact remains Karla's agent. Tarr is sent to Paris, where he passes a coded message to Alleline about "information crucial to the well-being of the Service". This triggers an emergency meeting between Gerald and Polyakov at the safe house, where Smiley and Guillam are lying in wait. Haydon is revealed to be the mole, and his interrogation reveals that he had been recruited several decades ago by Karla and became a full-fledged Soviet spy partly for political reasons, partly in frustration at Britain's rapidly declining influence on the world stage, particularly on account of
the failings at Suez. He is expected to be exchanged with the Soviet Union for several of the agents he betrayed, but is killed shortly before he is due to leave England. Although the identity of his killer is not explicitly revealed, it is strongly implied to be Prideaux, due to the method of execution (a quick snap of the neck) echoing the way he euthanises an injured owl earlier in the book, Prideaux's implied threat to execute a driver in Czechoslovakia in the same way that Haydon is killed, and a sense Smiley has of someone with Prideaux's background observing some of his later interrogations. Smiley is appointed temporary head of the Circus to deal with the fallout, and is still head at the start of the second book of
The Karla Trilogy,
The Honourable Schoolboy. == Background ==
