"through the courtesy of Mr. Moriarty" [FINA] As a student and practitioner of the latest forensic sciences as they pertained to the world of crime, Sherlock Holmes was on the cutting edge. He even wrote a number of monographs on topics related to crime. One might think that among them we might find "on the use of fingerprints to identify criminals." This is not the case. Why, we even had trouble finding trifling details about fingerprints in the entire Canon. Yet it's just a Trifle. If you have a question for us, please email us at trifles@ihearofsherlock.com. If you use your inquiry on the show, we'll send you a thank you gift. 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 is about the questionable judgment of the head of the Baker Street irregulars. 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.
