An update of Arthur Conan Doyle’s classic detective set in present-day London, Mark Gatiss and Steven Moffat’s Sherlock, begins on BBC One this summer.

Watson, a doctor, soldier and war hero, is fresh from military service in Afghanistan. A chance encounter brings him into the world of Sherlock Holmes, a loner, detective and genius. The two men couldn’t be more different, but Sherlock’s inspired leaps of intellect, coupled with John’s pragmatism, soon forge an unbreakable alliance.

Episode 1: ‘A Study In Pink‘
Sunday 25th July 2010

A woman in pink lies dead in a derelict house, the fourth in a series of impossible suicides. DI Lestrade is the best Scotland Yard has got, but even he knows he can’t compare to the young man who can tell a software designer by his tie or an airline pilot by his thumb.

Sherlock has a unique analytical mind, earning his living and staving off boredom by solving crimes. The weirder and more baffling the better…

Episode 2: ‘The Blind Banker‘
Sunday 1st August 2010

Watson’s new life is never dull – after all, he’s sharing a flat with Sherlock Holmes. But solving mysteries won’t pay the bills. The trouble is, though, that Sherlock’s idea of a visit to the bank is not quite what Watson had in mind.

Mysterious ciphers are appearing on walls all over London and anyone who sees them is dead within hours, from the glittering financial hub of the city to the heart of a travelling Chinese circus. Sherlock and Watson must decipher the deadly symbols before anyone else falls victim to the mysterious Black Lotus.

Episode 3: ‘The Great Game‘
Sunday 8th August 2010

Despairing of the ingenuity of London’s criminals, Sherlock is invited to take on what looks to be a very ordinary case – a young civil servant found on a railway line with his head smashed in. It seems to be open and shut – or so he thinks.

The curtain is about to rise on a terrifying game of cat and mouse as a crazed bomber pits his wits against Sherlock. A 20-year-old murder, a blood-soaked car, a rediscovered Old Master worth millions – it’s just the kind of adventure Sherlock and John relish, but who is behind these deadly puzzles? London is set to become a battle ground as Sherlock confronts the one person capable of beating him.
