Vintage Sherlock-Watson in Christmas special's official photo

LOS ANGELES: The upcoming " Sherlock" standalone, which will air on Christmas, has shared the first official picture, showing the detective and his partner Watson going old school.

The special takes place in the Victorian era. Sherlock ( Benedict Cumberbatch) and Watson ( Martin Freeman) are looking decidedly 1800s in the new photo from the upcoming Sherlock Christmas Special, which is set to take place in the Victorian era, said The Hollywood Reporter.

While Sherlock sits on a sofa, with a stern look on his face, Watson makes him comfortable on a side of the couch.

It will air on BBC One. The official Twitter page of BBC One posted,

The BBC special has had fans scratching their heads since late 2014, when a photo of Cumberbatch and Freeman showed the pair rocking Victorian-era clothing.

Executive producer Steven Moffat revealed in March it would be a standalone actually set in Victorian times, unlike the modern day reimagining.

No date has been set for the special.

Here's a teaser from the Christmas Special:
