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?

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.

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.
