If you loved watching Whyborne and Griffin piece together brutal murders and decode forbidden texts beneath the genteel facade of Widdershins, you’ll click with Peter Grant’s initiation into London’s magical crimes unit. In Rivers of London, a rookie cop apprentices to the last wizard-detective, untangling ghostly killings, interviewing river gods, and juggling casework that veers from stakeouts to spectral autopsies—with the same blend of banter, dread, and “oh no, that sigil really shouldn’t glow like that.”

Enjoyed the way Whyborne (shy scholar) and Griffin (seasoned investigator) grew from wary colleagues into something tender while unraveling a deadly cult? In A Marvellous Light, prickly magician Edwin Courcey and newly appointed civil servant Robin Blyth are forced into a magical conspiracy; their cautious trust becomes heat and devotion as they unpick a vicious curse knotted into Robin’s body and survive a perilous country-house entanglement. It’s that same chemistry—exasperation, protection, and quiet yearning—wrapped around a twisty case.

If the eldritch undertow in Widdershins—the sense that Whyborne’s translations might unlock something vast and unhuman—hooked you, Winter Tide turns that cosmic unease into an intimate, haunting investigation. Aphra Marsh, one of the last survivors of Innsmouth, teams with an FBI agent to recover stolen occult secrets; deep rituals, sea-dreamed memories, and ancient compacts blur human and inhuman. It captures the same uncanny awe without losing sight of the people caught in the abyss.

If Whyborne and Griffin’s dry quips amid cult-chasing made you grin, you’ll relish the verbal sparring in Sorcerer to the Crown. Zacharias Wythe—Britain’s embattled Sorcerer Royal—and the irrepressible Prunella Gentleman navigate dwindling English magic, treacherous society politics, and meddling fairy courts. The stakes are sharp, the magic can bite, and the dialogue crackles with the same buoyant charm that lightened the darkest corridors of the Ladysmith Museum.

If the ritual circles, sanity-scraping tomes, and world-grazing entities beneath Widdershins thrilled you, The Atrocity Archives delivers that flavor of dangerous magic with a techno-occult twist. Bob Howard, a computational demonologist press-ganged into a secret government agency, learns that the right math can summon horrors. Expect field ops against tentacled nightmares, clandestine cults, and soul-sapping paperwork—the same dark thrills of forbidden knowledge, just with more encryption and fire extinguishers.
