Tinker Tailor Soldier Spy

The time is 1973. The Cold War of the mid-20th Century continues to damage international relations. Britain's Secret Intelligence Service (SIS), a.k.a. MI6 and code-named the Circus, is striving to keep pace with other countries' espionage efforts and to keep the U.K. secure.

The head of the Circus, known as Control, personally sends dedicated operative Jim Prideaux into Hungary. But Jim's mission goes bloodily awry, and Control is forced out of the Circus, as is his top lieutenant, George Smiley, a career spy with razor-sharp senses. Estranged from his absent wife, Ann, Smiley is soon called in to see undersecretary Oliver Lacon. Smiley is to be rehired in secret at the government's behest, as there is a gnawing fear that the Circus has long been compromised by a double agent, or mole, working for the Soviets and jeopardising England. Supported by younger agent Peter Guillam, Smiley parses Circus activities past and present. In trying to track and identify the mole, Smiley is haunted by his decades-earlier interaction with the shadowy Russian spy master, Karla. The mole's trail remains cold until maverick field agent Ricki Tarr unexpectedly contacts Lacon. While undercover in Turkey, Ricki has fallen for a betrayed married woman, Irina, who claims to possess crucial intelligence. Separately, Smiley learns that Control narrowed down the list of mole suspects to five men. They are the ambitious Percy Alleline, whom he had code-named "Tinker," the suavely confident Bill Haydon, dubbed "Tailor," stalwart Roy Bland, called "Soldier," the officious Toby Esterhase, dubbed "Poor Man," and Smiley himself.

Even before the startling truth is revealed, the emotional and physical tolls on the players enmeshed in the deadly international spy game will escalate.
