BBC One is premiering a "Sherlock" mini-episode online on Christmas Day, according to Hypable.
The episode is entitled "Many Happy Returns" and will act as a prequel to the upcoming third season of the series.
Picking up two years after the second season finale when Sherlock supposedly died, the synopsis for the episode reads, “Sherlock has been gone for two years. But someone isn’t quite convinced that he’s dead …”
PBS has not commented yet on whether they will air the mini-episode or not.
The third season premieres in the UK on New Years Day, and will make its American debut on Jan. 19 on PBS.
