BBC One Releases New Trailer For 'Sherlock' Season 4 – TVWise

BBC One has dropped a new trailer for the upcoming the fourth season of Sherlock, which is set to hit screens in early 2017.
Based on the works of Sir Arthur Conan Doyle, Sherlock was developed for television by Steven Moffat and Mark Gatiss and is described as a modern take on the Holmes stories. The drama series focusses on Holmes and Watson as they consult on cases, usually for the Metropolitan Police Service. Sherlock is produced by Hartswood Films and stars Benedict Cumberbatch, Martin Freeman, Mark Gatiss, Rupert Graves, Una Stubbs and Amanda Abbington.
The three episode fourth season opens with the nation’s favourite detective, the mercurial Sherlock Holmes, back on British soil. Meanwhile, Doctor Watson and his wife, Mary, prepare for their biggest ever challenge: becoming parents for the first time. Executive Producer Steven Moffatt recently revealed to The Telegraph that this might be the final season, saying that it “absolutely could be” the show’s swan song.
The new trailer, which runs a little over a minute, gives a brief glimpse of Toby Jones’ (Wayward Pines), who is set to appear in episode two as a villain, and teaser the potential return of Andrew Scott’s Moriarty, which is set to be the focus of the opening episode:
