Following The Empty Hearse and The Sign of Three, Sherlock faces his most powerful adversary...
The BBC have today released a plot synopsis for the upcoming third episode of Sherlock's third season. Titled His Last Vow, Steven Moffat's series finale is based on Arthur Conan Doyle's final chronological Holmes tale, His Last Bow.
Hardcore followers of all things Sherlock will recall that Lars Miekelsen joins the show in the climax of its latest run as one-off antagonist Charles Augustus Milverton. His Last Vow also stars Amanda Abbington (Martin Freeman's wife) as Mary Watson, John's newly wed. Here's the plot synopsis in full: "A case of stolen letters leads Sherlock Holmes into a long conflict with Charles Augustus Milverton, the Napoleon of blackmail, and the one man he truly hates. But how do you tackle a foe who knows the personal weakness of every perso of importance in the Western world?"
Sherlock returns to BBC One with The Empty Hearse on New Year's Day, 2014.
