New riddles await the detective duo in "Sherlock" season 4, episode 1 titled "The Six Thatchers." Sherlock and Watson will uncover a mysterious case in Scotland Yard but what will gain Sherlock's interest is a small detail. Meanwhile, something will be revealed in Mary Watson's past.
In the official summary released by BBC for "Sherlock" season 4, episode 1, Sherlock will be interested in a very trivial matter in their newest case. Why does someone want to destroy the images of the late Prime Minister Margaret Thatcher? It might be just a coincidence or maybe there is some shady reason behind it. It added that the case will be linked to Mary Watson's past.
On the other hand, the newest preview for "Sherlock" season 4 is filled with emotions as Sherlock makes a surprise confession of his love. It might have something to do with Moriarty who is expected to make his move in episode 1.
The preview gives an ominous feel as the new villain Culverton Smith played by Toby Jones narrates, "The roads we walk have demons beneath... and yours have been waiting for a very long time," as Sherlock stands in front of a burning house.
In another scene, Sherlock tries to convince Watson that "it's not a trick, it's a plan." Though it's not revealed what this "plan" is all about, it seems very personal. A character tells Sherlock, "I want to hear you say it while Mycroft says "You can't do this." It seems like Sherlock will have to deal with something personal.
The villain asks Sherlock: "What's the very worst thing you can do to your very best friends?" But the most shocking scene is when an exhausted Sherlock stands in a dark room with his friends behind him as he makes an unexpected confession. "I love you," he said facing the camera.
Meanwhile, Steven Moffat hints at a possible season 5 and Cumberbatch's intension in reprising his role in a previous report. Fans can expect more updates and confirmation from the series creator as the new season debuts next month.
'Sherlock" season 4, episode 1, "The Six Thatchers" will air on Jan. 1 on BBC One.
