STAGE TUBE: Sneak Peek - PBS's SHERLOCK, SERIES 2, Premiering 5/6

Starting Sunday, April 22, PBS and MASTERPIECE will unlock a sneak peek of "A Scandal in Belgravia" - the enthralling premiere episode of SHERLOCK, SERIES 2 - on Facebook two weeks before it airs nationally, Sunday, May 6, on PBS stations.

The Facebook preview opens with Sherlock Holmes and Dr. Watson in the midst of Moriarty's plot from the nail-biting Series 1 conclusion. The duo is quickly thrown into a new case: one reaching to the highest stratum of the British government. How will the pair handle the addition of a mysterious new player? The game is on.

The PBS Facebook page, with more than 1.1 million fans, remains an active forum for fan discussion and excitement leading up to the series premiere.
