Though it's a little early for the holiday season, showrunner Steven Moffat has confirmed that Sherlock's Christmas special will take place during the Victorian era.
The special, which takes the detective duo back to the age in which they were first created, doesn't have an air date yet. Though, it's pretty safe to assume it will happen around Christmas.
"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."
