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 busts 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?

In the scene where Mary and John (Martin Freeman) are in bed, Mary likens an experience with their child to the horror film, The Exorcist. She then jokes how surprised she is that John hadn't noticed the child was born with 666 on her forehead. John corrects her by saying, "That's 'The Omen,'" with the word Omen pronounced more like "O-Man." In the film The World's End, Martin Freeman's character, Oliver, is nicknamed O-Man by his friends due to a birthmark shaped like a six on his forehead. See more »


When Sherlock first sees the Thatcher shrine, it contains a framed invitation to Mr. Welsborough from the Prime Minister in 1987. At the top, it has the arms of the United Kingdom and then in large letters says, "The Prime Minister The Rt. Hon. Mrs. Margaret Thatcher, F.R.S., M.P." followed by the invitation to a reception. However, this is an incorrect form of address, as the "Right Honourable" before a name replaces Mr., Miss, Ms. and Mrs. and is never used with it. Additionally, letterhead from the Thatcher era either simply had "10 Downing Street" below the coat of arms, or, for a personal invitation to an event, always stated both "The Prime Minister and Mr. David Thatcher" followed by the usual "request the presence of..." and the name of the invitee.

Mycroft Holmes: What you're about to see is classified beyond top secret. Is that quite clear? Don't minute any of this. Once beyond these walls, you must never speak of it. A D-notice has been slapped on the entire incident. Only those within this room, code-names Antarctica, Langdale, Porlock and Love, will ever know the whole truth. As far as everyone else is concerned, going to the Prime Minister and way beyond, Charles Augustus...

How absolutely dreadful to see a cult series like this to fall under the knife of terrible directing, unstructured scenario and horrible production. This episode is useless. It fails to tell a consistent story, it fails give a focused view, it ruins the series's integrity and leaves the viewer in confusion. Though I wouldn't say it was unexpected. Last year's episode had questionable qualities too, but being branded as a 'special' it had delivered at least a semi consistent experience and had integrity on it's own, as a 'special'. My most pessimistic expectations were that this sort of season beginning would mark the start of a lackluster chapter in Sherlock's story, more commercially oriented and rushed. But certainly not to the extent that this episode came to be. My expectations were low. But even in spite of this this episode was a complete and utter failure. The quality of 'The Six Thatchers' is more comparable to a mid season episode of Dr. Who, rather than an earlier Sherlock episode. Probably it's time to give Elementary a try.
