Professor Moriarty

Jan 14, 2026

“I must really know more before I leave him.” [MISS]  

Professor Moriarty. We know him as the arch-rival of Sherlock Holmes. In many ways, he was the original model for the supervillain. But what do we really know about him?

 

The answer is surprisingly little. And what we do know about him comes primarily from Sherlock Holmes. Join us as we dig a little deeper (or as deep as we can) on this Napoleon of crime. It's just a Trifle.

There's a new "Trifling Trifles" episode out — short-form content that doesn't warrant a full episode. We release these at the beginning of every month. The latest episode ponders a message we never quite see. This is a benefit exclusively for our paying subscribers. Check it out (Patreon | Substack).

 

Our Merch Store is now open: Trifles mugs, notepads, and oval stickers can be yours (or someone else's, if you'd like to make it a gift). Start shopping today.
