If you loved Felix Castor’s snarky, first-in-last-out casework—tin whistle in one hand, invoice in the other—tackling the Bonnington Archive haunting and fending off Juliet the lilu in gritty London, you’ll click with Harry Dresden. In Storm Front, Chicago’s only wizard-for-hire digs into a double murder steeped in black magic, dodges a summoned toad-demon, and wisecracks through mob goons and arcane blowback. It’s the same street-level, case-by-case urban sorcery, with a hardboiled voice and consequences that bite.

You enjoyed how Castor’s routine "simple haunting" at the archive unspooled into a murder cover-up and moral knots about what to do with the dead. In Rivers of London, probationary constable Peter Grant interviews a specter at Covent Garden and winds up apprenticed to Detective Nightingale, chasing a wave of possessive, face-mangling violence while negotiating with the River Thames’s capricious gods. It scratches the same investigative itch: procedure meets poltergeists, clues meet curses, and London itself becomes the accomplice.

If the bleak alleys, backroom exorcisms, and dirty bargains around Castor—like keeping Rafi’s demon on a precarious leash—hooked you, Sandman Slim goes even darker. James Stark claws his way back from Hell to Los Angeles to settle scores with the magicians who sent him there, carving through demons, sorcerers, and dive bars with equal ferocity. It’s the same gut-punch urban grime and moral fallout, only turned up to infernal heat.

Castor’s deadpan quips in the face of succubi, possessed friends, and clients who lie for a living keep the darkness from swallowing the story. In The Atrocity Archives, Bob Howard is an IT guy conscripted into the Laundry, a secret British agency where bad math summons worse demons. Expect office memos, eldritch abominations, and jokes sharp enough to cut a summoning circle—humor that, like Castor’s, defuses terror without deflating the stakes.

Felix Castor isn’t saintly—whether he’s choosing when to banish a ghost or when to bargain, his ethics get tested. Joe Pitt is cut from the same rough cloth. In Already Dead, the vampire PI hunts a missing girl through Manhattan’s clan politics while managing the Vyrus tearing through his body. Like Castor juggling Rafi’s demon and that archive job that was never just a job, Joe makes compromises that save lives—and cost him pieces of his soul.
