Speaking at the Kapow convention in London at the weekend, IGN report that Gatiss explained: “We knew after having a successful first run that the natural order would be to do three of the most famous [stories], being a version of ‘A Scandal In Bohemia’, a version of ‘The Hound Of The Baskervilles’ and a version of ‘The Final Problem’.”
Confirming who is writing which story, the show’s co-showrunner continued: “Steve [Moffat] wanted to do the twisted love story [‘A Scandal in Bohemia’], I’m doing the Gothic horror [‘The Hound Of The Baskervilles’] and Steve Thompson [writer of Series 1’s ‘The Blind Banker’] is doing ‘The Final Problem’.”
With regard to following up the events of the first series, Gatiss commented: “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.”
He added: “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.”
Gatiss revealed in February that Series 2 will begin shooting in May and will air on BBC One in the Autumn.
