“The Six Thatchers” is the new episode’s title and it marks the first new episode of Sherlock since the hit series’ 2015 Christmas special, “The Abominable Bride.” In fact, the Sherlock season four premiere arrives nearly two years after the end of the show’s third season.
The title of the Sherlock season four premiere is almost certainly a reference to Sir Arthur Conan Doyle’s 1904 short story “The Adventure of the Six Napoleons” swapping the French revolutionary with a more recent political figure.
The original story follows Holmes and Watson as they investigate a series of crimes tied to smashed statues. You can read the full story here.
Sherlock is written and created by Steven Moffat and Mark Gatiss, and inspired by the works of Sir Arthur Conan Doyle.
Sherlock season four premiere will arrive on January 1, 2017.
