Okay, as promised, the big clue in Reichenbach Fall to which Moffat alluded.
It’s there. Look at it. Rather, don’t look at it because it’s not there. Do you see?
Suicide. Suicide! That proves tha-… you don’t see it, do you? Okay, let’s back up.
This is The Sun. The media’s been hounding Holmes for a while now. Moriarty set up a story where Sherlock would be shamed, humiliated and killed. True to this plan, Sherlock commits “suicide”. But here’s the thing. He commits suicide on the same roof on which Moriarty killed himself. To any basic person walking onto the scene, they would see the body of Holmes and the shot body of Richard Brook, his hired actor.
Read the headline again. Suicide of Fake Genius. Not “Murder-suicide”. Not “Holmes kills Brook and then self”. Nothing. No reference to a second dead body. Not one. Why would they skip that? Why would they skip the chance to say Sherlock and his unwilling cohort died on the same roof at the same time?
Think back to Watson, to Hudson, and to everyone else. No one mentions Moriarty. None of them know at all. No one talking about Moriarty, no one discussing it, nothing. There’s only one logical conclusion here: No one knows he’s dead. Why would no one know he’s dead? Because he wasn’t there. Why would there be no body? Because it was moved.
Barring the idea that a henchperson carried away his body, Moriarty is still alive.
The missing clue isn’t how Sherlock lived. It’s that they both lived. See you in Series 3.
