Sherlock: 6 Unbelievable Moriarty Theories To Keep You Guessing

5. Moriarty Has A Twin Brother Or A Double

It's one of the more ridiculous theories out there, but the show has actually got previous form for it. In 'The Reichenbach Fall', the little girl in the sweet factory investigation screamed because she'd seen Sherlock. Everyone assumed that there was a mask or a Sherlock double, and Sherlock seemed to confirm the latter when confessing how he survived to Anderson. So what if Moriarty had a double too? It's certainly insurance for if anything happens to him, and though it's extremely unlikely that that was someone else we saw on that roof taunting Sherlock, there would be quite a few counter arguments €“ such as drug-induced hallucination. It's a long shot, granted, but it would certainly explain it. Also,iIt wouldn't be the first time Moffat hadn't told us the whole story, would it?
