The BBC has just confirmed via a series of Tweets, using the hashtag #221back (confused? See the featured image above) that the hit show Sherlock will indeed return.
Details are still a bit sketchy, but it's pretty clear that Andrew Scott as Moriarty will feature heavily – you may remember his appearance right at the end of last season, as a teaser for the new season.
The fact that he took over the BBC's twitter account for the duration of the tweets may have been a pretty obvious clue too!
Filming is due to begin on January 2015. Whilst this does appear to be a long way off yet, it shouldn't come as much of a surprise really, considering how difficult it must be to get both Martin Freeman and Benedict Cumberbatch together at the same time!
What we do know is that there will be a one-off special, most likely a Christmas Special, and this will be followed by a three episode fourth season.
Stay tuned for official release dates the minute there come available!
