Late last year, BBC One tweeted a photo of Sherlock stars Benedict Cumberbatch and Martin Freeman decked out in Victorian attire and, unsurprisingly, fans of the show immediately launched into speculation as to the clue’s meaning.
Now Variety reports that the show’s co-creator Steven Moffat has confirmed that the upcoming Sherlock special in question will have the lovable duo time traveling back to Victorian London—the world of Sherlock Holmes’s original author, Sir Arthur Conan Doyle.
Pajiba reports that this confirmed time-period hop has thrown gasoline on the embers of a rumored Doctor Who crossover, though Moffat—who is also Doctor Who‘s showrunner—has reportedly denied the possibility.

Moffat told Entertainment Weekly that the special is a standalone affair, separate from the upcoming fourth season which will air in 2016. “We wouldn’t have done the story we’re doing, and the way we’re doing it, if we didn’t have this special,” said Moffat. “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.”
As of yet, the special has no official airdate. Here’s to hoping we see Cumberbatch in a cummerbund!
