In Bern, Smiley begins his interrogation of the hapless Soviet diplomat, Grogoriev, who proves to be a most willing informant, particularly when they threaten to reveal photos of him kissing the pretty Russian consular clerk to his dragon of a wife. He reveals how he first came into contact with Karla while attending a trade conference in Moscow. He pays the monthly clinic costs out of the money he withdraws from the bank and sends weekly reports to Karla via the Embassy courier on the girl's appearance, her manner and her attitude. He assumed the girl was Karla's daughter, but isn't sure. Knowing that he has finally found Karla's weak point, George Smiley sends him a letter with a proposition that, George hopes, Karla will find impossible to refuse. On the appointed night, George, Peter Guillam and Toby Esterhase with his team wait patiently at the East/West checkpoint in West Berlin to see if their plan has worked.

The conclusion of the series supposedly takes place on the Oberbaumbrücke in Berlin, one of the East-West checkpoints, yet it features the Lady Bay Bridge in Nottingham, UK. The filmmakers chose the bridge in the UK due to its similarity to the bridge and dressed it to resemble the German bridge as closely as possible. This is explained on the DVD production notes as a financial decision. See more
