The main question driving Tinker, Tailor, Soldier, Spy is “Who is the spy at the top of the Circus?” and we watch knowing the puzzle will be solved and traitor revealed. Driven by the active question “Who is the mole?”, Act one sets out the pieces of the puzzle and introduces George Smiley. Driven by the active question “Will Smiley uncover the mole?” act two is woven round a series of flashbacks and shady manoeuvres within the Circus. Smiley roots out the mole, and, driven by the act three active question “Will Smiley catch the mole?”, he sets a trap, confronts Hayden and is reinstated in the Circus as Control.
