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.

Promising laughter, tears, shocks, surprises and extraordinary cases, Season four will begin with the nation's favorite detective, the mercurial Sherlock Holmes, back once more on British soil, as Doctor Watson and his wife, Mary, prepare for their biggest ever challenge - becoming parents for the first time. This new season will consist of three 90-minute episodes. The first of the three feature-length episodes in Sherlock Season 4 will be directed by Rachel Talalay, who has worked as a director, producer, and professor in film and television for more than 25 years, having previously directed Doctor Who, The Flash and The Wind in the Willows.

Sherlock is written and created by Steven Moffat and {Mark Gatiss, and inspired by the works of Sir Arthur Conan Doyle. Sherlock is produced by Sue Vertue and the executive producers are Beryl Vertue, Mark Gatiss and Steven Moffat for Hartswood Films, Bethan Jones for BBC Cymru Wales and Rebecca Eaton for Masterpiece. It is distributed internationally by BBC Worldwide. Take a look at the new photos below for Sherlock Season 4.
