The BBC just tweeted a new promotional picture for the upcoming “Sherlock” special, with the detective and the good doctor in old-time clothing. You know what that means, Holmes and Watson are going back in time!

In an interview way back with Entertainment Weekly in March, co-creator Steven Moffat basically confirmed what our eyes are telling us now: the 90-minute will take place in the Victorian age. Said Moffat, "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".
