“Sherlock” Fourth Series Gets Another Trailer

The BBC has debuted the new trailer for the upcoming fourth series of “Sherlock”. Confirming the much darker tone for this new batch of three telemovie-length episodes, the new series will premiere on January 1st in the UK and US.

The first episode, “The Six Thatchers,” marks the first new episode of “Sherlock” since the 2015 Christmas special, and almost two years removed from the show’s third season.
