Sherlock Season 2

After the high ratings for "A Study in Pink", the BBC were reportedly eager to produce more episodes. On 10 August 2010, it was confirmed that Sherlock had been renewed for a second series. At the 2011 convention, Gatiss confirmed which stories would be adapted, and that the writers of the first series would each write an episode for series two. Acknowledging that "A Scandal in Bohemia", "The Hound of the Baskervilles" and "The Final Problem" are amongst the best-known Holmes stories, Gatiss explained, "We knew after having a successful first run that the natural order would be to do three of the most famous [stories]." "There's the question of how to go out on a cliffhanger and then the thematic things of the three stories, where we were trying to get to and what Sherlock and John's relationship is a little further on. You can't just go back to: 'You have no emotions.' 'I don't care.' You've got to move on somewhere and make sure the other characters have something of a journey too." Paul McGuigan directed the first two episodes, and Doctor Who director Toby Haynes handled the last one. The second series of three 90-minute episodes was initially planned to air in late 2011, but was delayed until early January 2012. "A Scandal in Belgravia", written by Steven Moffat and directed by Paul McGuigan, was first broadcast on 1 January 2012. Loosely based on "A Scandal in Bohemia", the episode depicts Holmes's quest to retrieve compromising photos of a minor royal held on the camera phone of Irene Adler (Lara Pulver), a ruthless and brilliant dominatrix who also trades in classified information extracted from her rich and powerful clients. The resolution of Sherlock's faked suicide from the roof of St Bartholomew's Hospital in London attracted speculation in social media and newspapers. Mark Gatiss wrote, "The Hounds of Baskerville", which investigates the strange activities at a military base. Aware that The Hound of the Baskervilles, first published in 1902, was one of the most famous of Conan Doyle's original stories, Gatiss felt a greater responsibility to include familiar elements of the story than he does when adapting the lesser-known stories. Russell Tovey appeared as Henry Knight, a man whose father was ripped apart by a gigantic hound on Dartmoor twenty years earlier. Directed by McGuigan, the episode was first broadcast on 8 January 2012. The second series concluded with "The Reichenbach Fall". Steve Thompson wrote the episode, which was directed by Toby Haynes, who had previously directed many of Moffat's Doctor Who episodes. First broadcast on 15 January 2012, the episode follows Moriarty's plot to discredit and kill Sherlock Holmes, concluding with Holmes faking his suicide. It was based upon Conan Doyle's story "The Final Problem", in which Sherlock and Moriarty are presumed to have fallen to their deaths from the Reichenbach Falls in Switzerland. Moffat felt that he and co-creator Gatiss had outdone Conan Doyle in their version of Holmes' fall and Moffat added that, in that much-discussed sequence, there was still "a clue everybody's missed".
