Unlocking Sherlock

Find out how writers Steven Moffat and Mark Gatiss created the television hit Sherlock, taking Sir Arthur Conan Doyle's original adventures of the Victorian super sleuth and transforming them into a worldwide sensation. Steven and Mark take us through the versions of Holmes that have inspired them - the original stories, the factual inspirations, the thousands of film versions - to arrive at the thoroughly modern Sherlock. And we go behind the scenes on set with the stars of Sherlock. Featuring interviews with lead actors Benedict Cumberbatch and Martin Freeman.
