SHERLOCK Creator Steven Moffat Reveals Season Three Key Words that Hint at Upcoming Episodes

Starring Benedict Cumberbatch and Martin Freeman as Holmes and Watson, Sherlock is the BBC's popular series currently prepping for a third and possibly final season.

Benedict Cumberbatch (Star Trek 2, Starter For Ten) and Martin Freeman (The Hobbit, Hitchhiker's Guide To The Galaxy) star in Sherlock, a thrilling, fast-paced update of Arthur Conan Doyle's classic detective, set in present-day London. In this unique adaptation, the iconic details from Conan Doyle's original books remain. They live at the same address, are only interested in the bizarre and, somewhere out there, Moriarty is waiting for them.

Sherlock also stars Rupert Graves (God On Trial, Midnight Man) as Detective Inspector Lestrade, Scotland Yard's finest, largely because Sherlock allows him to take credit for his deductions, and Una Stubbs (EastEnders, The Catherine Tate Show) as Mrs Hudson, their long-suffering housekeeper.

Sherlock is expected to return for it's third season in the Fall of 2013. At the Edinburgh TV festival this past week, co-creator and writer Steven Moffat revealed that the three Arthur Conan Doyle themed key words for this season are: Rat, Wedding, and Bow. This follows the trend he started last year by announcing the season 2 key words Woman, Hound, and Fall -- which lead to the episodes A Scandal in Belgravia, The Hounds of the Baskerville, and The Reichenbach.

The three key words from this upcoming season seem to point to the stories The Giant Rat of Sumatra, The Noble Bachelor, and The Last Bow.

Sherlock is co-created by the hugely talented partnership of Steven Moffat (Doctor Who, Coupling) and Mark Gatiss (The League Of Gentlemen, Crooked House, Doctor Who) and produced by Sue Vertue (Coupling, The Cup).
