The Six Thatchers

Sherlock waits to see where Moriarty will make his posthumous... More 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?

Sherlock faces perhaps the most chilling enemy of his long... More career: the powerful and seemingly unassailable Culverton Smith - a man with a very dark secret indeed.

Holmes and Watson travel to Europe to escape Moriarty's vengeance.
