The future of Sherlock might be up in the air, but series writer Steven Moffat is already talking about which Holmes stories he'd like to adapt next.
A total of 60 adventures were written by Arthur Conan Doyle, leaving plenty of material for Moffat and Mark Gatiss to mine... if the show returns.
"Very, very few of the stories adapt very easily, because properly paced, you could get about 20 minutes out of a Sherlock story," Moffat explained to Vulture.
"We've done 'The Hounds of Baskerville'. We've sort of done 'The Sign of the Four' in different ways [as 'The Sign of Three']. The rest of them you can't really adapt into movies.
"You have to come up with a new story involving elements of the short stories. Maybe taking a villain from one and combining them with the crime from another. There are loads of great sequences and great ideas. There aren't feature-length ideas."
All that being said, there are a few stories that he's got his eye on as potential inspiration for future episodes...
"Mark's always wanted to do 'The Red-Headed League' [and] there's 'The Engineer's Thumb', which is a slightly mad story that doesn't have a proper ending.
"There's an element of 'The Greek Interpreter' that I think is really exciting, which hasn't been done, because in our version of events Irene Adler is still out there. There's always that.
"Now we know she and Sherlock actually still text each other. What would happen if they ever met again? There are those things we can do, but we simply have no idea whether we'll be doing them or not."
Personally, we'd be keen to see an adaptation of 'The Adventure of the Cardboard Box' - trust us, it's more exciting than it sounds...
