BBC’s “Sherlock” debuted in 2010 as the latest in a string of film and television adaptations of Sir Arthur Conan Doyle’s lasting character. What separated Mark Gatiss and Steven Moffat’s Holmes iteration from the rest was its modern setting and creative storytelling techniques. Slated for a 2017 release, the first series 4 trailer has been released, along with the titles of the first two episodes from the forthcoming season.

“Sherlock” series 3 concluded in 2014 with the critically-acclaimed “His Last Vow.” 2016 saw the Emmy-winning made-for-TV movie special “The Abominable Bride” air, which departed from previous episodes in its experimental structure. While initially polarizing, “The Abominable Bride” proved a masterful means of portraying Benedict Cumberbatch and Martin Freeman as Holmes and Dr. Watson respectively in the original setting of Conan Doyle’s stories.

As the trailer for series 4 elucidates, Sherlock’s return to England under the premise of investigating James Moriarty’s (Andrew Scott) purported return plays a prominent role. Series 3 with its onus on mind palaces delved into Sherlock’s past, and series 4 promises to probe our favorite consulting detective’s personal life even more. From the trailer, it appears season 4 may assume a darker role with ominous warnings from Sherlock that “something’s coming,” and Molly Hooper (Louise Brealey) chiding “for Christ’s sake Sherlock, it’s not a game.” The always enjoyable Toby Jones joins the cast as what looks like a formidable foe.

Initial episode titles have been revealed as “The Six Thatchers,” and “The Lying Detective.” Reportedly, these are based on “The Adventure of the Six Napoleons” and “The Adventure of the Dying Detective.” The third episode title has been left a mystery, for now at least.
