John and Lestrade try to move on with their lives after Sherlock's apparent death. However, Anderson believes he is still alive.

Two years after the devastating effects of The Reichenbach Fall, Dr John Watson has got on with his life. New horizons, romance and a comforting domestic future beckon; but, with London under threat of a huge terrorist attack, Sherlock Holmes is about to rise from the grave with all the theatricality that comes so naturally to him. It's what his best friend wanted more than anything, but for John Watson it might well be a case of 'be careful what you wish for'. If Sherlock thinks everything can be just as he left it though, he's in for a very big surprise. Written by BBC

As Lestrade fumes over his constant inability to convict the Waters gang of bank robbers, Holmes prepares for his role as best man at Mary and John's wedding. His speech, initially bizarre, turns out to be a moving tribute to his friend whilst he also contributes two anecdotes of recent cases, both unsolved. The first concerns a young guardsman whose life John saved after he was the victim of a 'locked room' attempted murder. The second involves a man who uses the identities of the recently deceased to date different women. As he looks around the wedding party, Holmes suddenly realizes their connected solutions, which also involve Watson's former commanding officer, disfigured war hero Major Sholto.

Lady Elizabeth Smallwood is one of many victims of master blackmailer and media tycoon Charles Augustus Magnussen and asks Holmes to retrieve some incriminating letters for her. Having cultivated Magnussen's secretary Janine, Holmes breaks into Magnussen's office but is confronted by a mysterious black-clad woman, who shoots him. He recovers in hospital and goes after her to discover her identity and reason for wanting the blackmailer dead before he and Watson visit Magnussen at his country house for a confrontation and shoot-out.
