Benedict Cumberbatch (Sherlock) and Martin Freeman (John Watson) look dapper in new photo from the upcoming ‘Sherlock’ Victorian Christmas Special.

“The special is its own thing. We wouldn’t have done the story we’re doing, and the way we’re doing it, if we didn’t have this special. It’s not part of the run of three episodes. So we had this to do it – as we could hardly conceal – it’s Victorian. [Co-creator Mark Gatiss] and me, we wanted to do this, but it had to be a special, it had to be separate entity on its own. It’s kind of in its own little bubble.” – Moffat told Entertainment Weekly

‘Sherlock’ Christmas Special will air on December 25 in the U.K.
