Well, less a mini-episode, more an extended teaser/trailer, with a few clues of what's happened to a few of the characters in the two years since the last season's timeline finished, and what's to come. As fans eagerly awaits the new season premiere next week, a little taste has been provided. The first show, 'The Empty Hearse", airs on BBC1 next Wednesday, January 1st at 21:00, hopefully available on the BBC iplayer shortly thereafter. Happy Holidays!
