S01E01 A Mother's Assistance
Once more, George Smiley is brought out of retirement to look into the murder of an old colleague.
Smiley continues his investigation, now looking for a man named Otto in a small fishing community, only to find his decaying body in his boat, and a mysterious chalk mark he's seen before. Smiley talks to the now-perpetually afraid woman.
Called out of retirement to settle the affairs of a friend, Smiley finds his old organization, the Circus, so overwhelmed by political considerations that it doesn't want to know what happened. He begins to follow up the clues of his friends past days, discovering that the clues lead to a high person in the Russian Secret service, and a secret important enough to kill for.
