The official Sherlock Twitter account has released the first official image for series 4. The image shows a more somber mood for our heroes. Benedict Cumberbatch‘s (Doctor Strange) Sherlock and Martin Freeman‘s (The Hobbit: An Unexpected Journey) John Watson both have seemingly concerned looks on their faces. Could this be a sign as to what is in store? If you haven’t already, see the teaser trailer below.
Sherlock Series 4 will return to our TVs in 2017. How excited are you? Do you have any theories as to what might happen? Let us know in the comments below, or on our Twitter.
