Some fan theories are so bizarre that most of us don’t even consider it a possibility. We’ve had some crazy fan theories that change the way we look at our favourite movies but we rarely come across original fan theories which are backed by some legitimate evidence. Moriarty is one of the most discussed figures of contemporary pop-culture and his escape from death still baffles us.

However, there’s a possibility that the real identity of Moriarty in the show has been uncovered. Andrew Scott isn’t Moriarty but a pawn in the bigger game. Sherlock Holmes’ mother, Mrs Holmes, is Moriarty.


Here are a few facts that help us validate this theory – 

1. Moriarty is a Professor of Mathematics

Moriarty is a Professor of Mathematics in the original Conan Doyle stories – something that has not been carried over onto Sherlock with Andrew Scott’s Jim Moriarty. However, in His Last Vow, we learn that Sherlock’s mother is a genius mathematician. This is the first parallel you can draw between Moriarty and Mrs. Holmes.

2. Moriarty and Mrs. Holmes have both written books that sound awfully similar

As seen in His Last Vow, Mrs. Holmes wrote a book called The Dynamics of Combustion. In the original stories, Moriarty was the one to author a book called The Dynamics of an Asteroid. This subtle little clue might just go a long way in the show.


Here’s an excerpt from Sherlock‘s episode His Last Vow:

We don’t believe that the theory is accurate. But I won’t let my dreams be dreams!
