Guess who's back from 221 B, Baker Street, for an extended special episode this Christmas? Yes, after a long wait and all the 'no-season-four-until-2017' scare, which, by the way, has been scheduled for 2016, the Sherlock Victorian Christmas Special 2015 teaser is finally out. We can't wait to watch the Sherlock-Watson duo reunite in their new avatars, especially after the first look of the pair was released some time back.

Now don't get too excited, because we don't know the exact date yet. But, this teaser will get you rumbling with excitement for sure! Check it out.
