Ok, so we begin where we left off with Sherlock (BBC1, Sunday) – with Moriarty at a London swimming pool which is kind of the Reichenbach Falls. Well, it's wet and it's where the big showdown with Moriarty happens. But he doesn't kill Sherlock, because he gets a phone call from a lady, who turns out to be Irene Adler.
Ah yes, the woman, the only one who ever meant anything to Holmes, from Conan Doyle's A Scandal in Bohemia. This story is called A Scandal in Belgravia. Stephen Moffat seems to be moving stuff from Europe to London, as well as shunting everything 120 or so years forward in time.
In Sir Acd's story, a European royal house is threatened with ruin through blackmail. There are compromising photographs. Here it's our monarchy, and the pictures are on an iPhone.
