New Sherlock promo images have been released for series 4 and added to the gallery.
The new images show Sherlock, Mary, John and the new baby Watson.
The BBC have also released a new decidedly ominous teaser for the show (below) and a plot summary for the first episode The Six Thatchers:
Sherlock waits to see where Moriarty will make his posthumous move. One mysterious case in particular baffles Scotland Yard – but Sherlock is more interested in a seemingly trivial detail. Why is someone destroying images of the late Prime Minister Margaret Thatcher? Is there a madman on the loose? Or is there a much darker purpose at work? Something with its roots deep in Mary Watson’s past…”
The BFI have a preview of the final episode of Sherlock series 4 on the 12th January 2017 (3 days before air). Tickets are on sale to champion members on Monday 5th December, to members on 6th December and public booking on the 13th December (please note that these previews usually sell out to members and the BFI do not keep tickets back for public sale).
