The hunt for clues on Sherlock begins on the first day of 2017
The series will kick off “The Six Thatchers” mystery on New Year’s Day — Sunday, Jan. 1, 2017.
Sherlock features Toby Jones as a new villain in season 4 and this may end up being the show’s last season.
Leading actor Benedict Cumberbatch told the UK edition of GQ magazine :“it feels like the end of an era, to be honest.”
Even if Sherlock were to go on, its fourth season “goes to a place where it will be pretty hard to follow on immediately,” the actor added.
