New pictures from the Sherlock Christmas special

The BBC has released the first retro promotional images for the Sherlock Christmas special.

In the images, Benedict Cumberbatch and Martin Freeman wear Victorian costumes as a nod to their characters' origins, with Freeman sporting Watson's trademark bushy moustache.

The pair are expected to once again go up against Andrew Scott's nefarious Moriarty, who made a surprise reappearance at the end of last season.

The episode will air as part of the BBC's Christmas line up, and will be followed by a fourth series in 2016. Here's hoping the 'tash spans both.
