After a long time of hiatus Benedict Cumberbatch's Sherlock Holmes isn't done yet, to prove BBC unveils its latest "Sherlock Holmes" Season 4 Trailer. Notably, it brings a lot of intriguing matters for the fans. One of the biggest, Toby Jones supposed character in the TV series. A lot of fans wonder still who will he be and how he will be a villain. And, the question seems to be answered now.

"Toby Jones will play the villain in this season, and in the teaser, he seems to exert power over Cumberbatch's Holmes." This became evident in the latest teaser trailer of BBC's forthcoming show. In the statement, it seems that he knows a lot about Sherlock. In the news, it says that he will use this leverage to bring down Doyle's character.

Who could he really be? Apparently, the "Sherlock Holmes" Season 4 trailer opens up the possible undisclosed role of Toby Jones as Sherrinford. He is supposedly the evil third brother of the Holmes. And, he's not well known to many.

A few weeks ago, show creators Steven Moffat and Mark Gatiss noted the word, Sherrinford when they were in Comic-Con. Now, it's biggest evidence that this could really be the role of Jones.

Now, Toby Jones' Sherrinford would really know a lot about his brother as shown in "Sherlock Holmes" Season 4 trailer. Clearly, he can dangerously use that knowledge for his personal interest.

The only question left now is why he would want to destroy Sherlock. Surely, it will be well explained on the show's airing. Although Toby Jones will still be on the 2nd episode, it will be after "The Six Thatchers".

To sum up, "Sherlock Holmes" Season 4 trailer presents thrilling promise of exciting new adventures. Clearly, it's a must watch! So, the fans should see it on January 1st on BBC.
