The Irregulars is based in part on the Baker Street Irregulars, a group of street urchins in Arthur Conan Doyle’s original Sherlock Holmes novels that helped Watson and the famous consulting detective gain a street-level view on London and handle some of the busy work of solving mysteries.

Netflix’s version, created by Tom Bidwell, seems to take things in a far moodier and spookier direction.

The Baker Street Irregulars have appeared in some Sherlock Holmes films and television shows over the years (recently reworked as a “Homeless Network” in BBC’s Sherlock), but The Irregulars’ choice to seemingly position Holmes and Watson as people taking advantage of these young kids seems ripe for some interesting stories.
