Last month, it was announced that the Sherlock Season 4 premiere will kick off the New Year on Sunday, January 1, airing on the BBC for fans in the U.K. and on PBS for U.S. viewers. With fans chomping at the bit for these episodes to finally arrive, the BBC has unveiled photos from this upcoming season of Sherlock, which gives us our first look at John Watson's (Martin Freeman) baby, and the new villain, Culverton Jones, played by Toby Jones. It's possible that these new photos could pave the way for a trailer to arrive soon, but that has yet to be confirmed.

Toby Jones will star in the second episode of the brand new three-part season as Culverton Jones. This character was featured in the Arthur Conan Doyle story "The Adventure Of The Dying Detective." Episode two will be directed by Nick Hurran, who was Emmy-nominated for Outstanding Directing for a Miniseries for "His Last Vow", a Sherlock Season 3 episode. The first episode this season has been confirmed to be called The Six Thatchers.

There are already theories that the title could be a reference to the Sir Arthur Conan Doyle story The Adventure of the Six Napoleons, which was published in 1904, where the duo investigated a number of crimes related to broken statues. It's possible this new story could swap out the French military leader for the Great Britain Prime Minister Margaret Thatcher, but no official plot details have been given for this episode yet. With the premiere date getting closer and closer, hopefully new plot details will surface soon.
