BBC shares new picture from ‘Sherlock’ Victorian special

The self-contained episode is expected to air during this year's Christmas TV season

The BBC has shared a new picture from Sherlock‘s forthcoming Victorian special.

The image, which shows stars Benedict Cumberbatch and Martin Freeman looking dapper in period costume, was tweeted by BBC One last night.

The BBC has yet to announce when the special will air, but it is expected to be during this year’s Christmas TV season. Little is known about the episode, but the show’s co-creator Steven Moffat confirmed earlier this year that it will be a self-contained special set in Victorian England.

“The special is its own thing,” Moffat explained back in March. “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.”

The special will be followed by Series Four of the hit detective drama, which will feature three additional new episodes. Moffat’s Sherlock co-creator Mark Gatiss hinted earlier this year that tragedy is to come in the show’s new series, which will be its first since 2014.
