Sad news, Sherlock fans - Mark Gatiss has confirmed it'll be at least another two years until the next series.
Holmes viewers will have to wait until 2016 at the earliest to see a fourth series - due to the programme's format.
Each season is made up of three 90-minute 'films', and the show's boss admitted it makes it difficult to work any quicker.
Speaking at a fan Q&A session in Brazil, he said: "Writing three films is quite a lot of work and then getting everyone together… [it's] increasingly difficult to get everyone's diaries to align, so we couldn’t really do more than three every couple of years I’m afraid.
"I mean, we'd certainly like to reduce the time, but by the time we've finished and then everyone starts gearing up again, it roughly takes that long."

It almost didn't end up like this, with Mark revealing the show was originally meant as a six-part series of 60-minute episodes - and Sherlock would have been very different.
He explained: "We ended up doing 90 minute episodes by accident. We made a 60 minute pilot and that was going to be the format of the series. We were going to have six, hour-long episodes.
"I think if we’d done that everything would be very different. We would do one where it was mostly Dr Watson, or Mrs Hudson investigates or something like that."
