If you loved trailing Abigail and Jackaby through New Fiddleham’s crime scenes—salt, iron, and all—while unmasking a killer, you’ll race through The Screaming Staircase. Lucy Carlyle, Anthony Lockwood, and George Cubbins run a tiny ghost-hunting agency and take on the infamous Combe Carey Hall, where a murderous haunting culminates on the titular staircase. The sharp sleuthing, perilous hauntings, and found-on-the-scene ingenuity echo the way Jackaby and Abigail parse eerie evidence and outwit deadly specters.

Miss the dry quips and oddball casework—like Jackaby’s deadpan pronouncements, Jenny Cavanaugh’s spectral assists, and Douglas the duck’s unforgettable presence? Rivers of London follows PC Peter Grant as he’s apprenticed to wizard-detective Thomas Nightingale. From interviewing river spirits to tracing a murderous Mr. Punch through Covent Garden, the humor, weird evidence, and procedural beats scratch the same itch as Abigail’s wry narration alongside Jackaby’s arcane methods.

If the gaslit streets, lurking monsters, and proper-yet-perilous vibe of Jackaby’s New Fiddleham hooked you, Soulless delivers a similarly delightful Victorian urban fantasy. Alexia Tarabotti, a preternatural who can neutralize supernatural powers by touch, tangles with the Bureau of Unnatural Registry, vanishing vampires, and the irascible werewolf Lord Maccon. It’s the same blend of society, snark, and supernatural skulduggery that made Abigail’s first case so moreish.

If what charmed you was Abigail learning the craft—Jackaby teaching her to notice what others miss, from subtle auras to stray clues—then The Beekeeper’s Apprentice is a perfect fit. Teen prodigy Mary Russell meets a retired Sherlock Holmes on the Sussex Downs and becomes his pupil, matching wits through cryptic cases, coded messages, and a chilling kidnapping plot. That evolving teacher–student bond mirrors the way Abigail and Jackaby’s partnership deepens with each deduction.

If Jenny Cavanaugh’s ghostly interventions and Douglas-the-duck’s memorable assists were highlights, you’ll enjoy the way Storm Front pairs wizard PI Harry Dresden with Bob the skull—an air spirit who’s equal parts research assistant and snark engine. As Harry chases a series of heart-exploding murders, tangles with Gentleman Johnny Marcone, and fends off a swarm of magically animated scorpions, Bob’s irreverent counsel proves as crucial (and entertaining) as Jackaby’s household allies.
