Sherlock fans will have a little while to wait to see their favorite crime solver back in action.
The cast have already filmed a Victorian-era special episode, scheduled to air this winter.
However, Sherlock showrunner Steven Moffat has revealed that the fourth season of the popular BBC drama is not scheduled to begin filming until spring 2016.
Moffat said that the fourth season will involve "Consequences. It's consequences." he said.
"Chickens come to roost. It's dark in some ways - obviously it's great fun and a Sherlock Holmes romp and all that - but there's a sense of things coming back to bite you."
Benedict Cumberbatch and Martin Freeman both have packed schedules, which could be part of the reason that we have to wait so long for the new series.
So all we really know so far about season four is that it will carry on where the third season left off, with this year's special episode taking place outside regular Sherlock continuity.
