" Alec Leamas has ended his time in Berlin. Or his time has ended him. The last of his Eastern agents has been killed, like the others, by the Abteilung. Back at the Circus, Leamas is put on the shelf. He turns to drunkenness and dishonesty and finally disappears from view, a seemingly broken man. But unknown to anyone except George Smiley and his master, Control, Leamas has been given his toughest mission ever. He will have to be himself but more so. He will have to fight off the inevitable softening of middle age and wait a little more before he can come in from the cold. Not even Leamas can know the plan of which he is the instrument."
