Sherlock was announced as a single 60-minute drama production at the Edinburgh International Television Festival in August 2008, to be broadcast in Autumn 2009, with the intention of producing a full series should the pilot be successful. The BBC decided not to transmit the pilot, as is common industry practice, but commissioned three 90-minute episodes. This is the 60 minute pilot.

The special takes viewers on a personal voyage through the versions of Holmes that have served as inspirations for the new series – the original stories, their factual origins, hundreds of film adaptations – to arrive at their thoroughly modern Sherlock. Moffat and Gatiss explain the challenges they encountered adapting the original adventures of the iconic super-sleuth. The special goes behind the scenes on the set of the hit television series, and includes interviews with actors Benedict Cumberbatch, Martin Freeman and Lara Pulver, who talk about the reinvention of their fictional characters.

Sherlock's back! The world's greatest detective comes back from the dead. But how did he do it? We go behind-the-scenes of the first episode cast read-through, with Benedict Cumberbatch and Martin Freeman where the answer to television's greatest mystery was first revealed. And we uncover the unlikely friendship between Sherlock Holmes and Dr John Watson.

The stars of Sherlock talk about the women in the life of TV's greatest detective. Sherlock Holmes may be great at solving mysteries, but he's clueless about women.

And Mrs. Hudson's always there to pick up the pieces.

We meet the great villains who've battled with TV's greatest detective. There's Jim Moriarty, his nemesis. There's Charles Augustus Magnussen, the only man Sherlock Holmes truly hates. And then there's Mycroft Holmes - Sherlock's brother and the last word in sibling rivalry. All of them have had influence over those closest to Sherlock. And all of them cause him grief.

We've been here before — but what if this wasn't the modern day but the late Victorian period? What if the world's most famous consulting detective and his best friend lived in a Baker Street of steam trains, hansom cabs, top hats and frock coats? Welcome to Sherlock in 1895. Holmes and Watson must investigate a mysterious ghostly bride prowling the streets with an unslakable thirst for revenge.
