The trailer for the final episode of Sherlock. Apparently the episode was written by Steve Thompson, who also wrote the second episode of last season, The Blind Banker. Hmm, not sure how I feel about this, The Blind Banker is absolutely the weakest of all the five episodes of Sherlock we’ve seen so far. The trailer looks great,though, especially with that song. The linked article contains some spoilers about the theme of the episode, but is pretty much spoiler-free about the content (except for the obvious one that it focuses on Moriarty, but I think almost everyone is already spoiled about that).
