Synopsis

Equipped with fresh insights, Smiley sought out Jim Prideaux, a former agent who had long since retired to a quiet life as a schoolteacher. In his final days, Control had confided in Prideaux, dispatching him on a clandestine mission behind the Iron Curtain – a quest to identify the traitor within the Circus, the one known only as Tinker, Tailor, Soldier, Rich man, or Poor man.
