A magical serial killer is stalking the Occult town of Wrackton. Hypnotic whistling causes victims to chew their own tongues off, leading to the killer being dubbed the Whistler (original, right?). But outside the lack of taste buds and the strange magical carvings on the victims’ torsos, the murderer leaves no evidence. No obvious clues. No reason—or so it seems.
Enter the Undetectables, a detective agency run by three witches and a ghost in a cat costume (don’t ask). They are hired to investigate the murders, but with their only case so far left unsolved, will they be up to the task?
Mallory, the forensic science expert, is struggling with pain and fatigue from her recently diagnosed fibromyalgia. Cornelia, the team member most likely to go rogue and punch a police officer, is suddenly stirring all sorts of feelings in Mallory. Diana, the social butterfly of the group, is hitting up all of her ex-girlfriends for information. And not forgetting ghostly Theodore—deceased, dramatic, and also the agency’s first dead body and unsolved murder case.
With bodies stacking up and the case leading them to mysteries at the very heart of magical society, can the Undetectables find the Whistler before they become the killer’s next victims?
The tagline says it all: Be gay, solve crime, take naps. If that sold you, the book will mostly deliver. Fun and easy to read, but with real emotional weight when it matters.
The Undetectables is a paranormal cozy mystery set in a queernorm occult town, and what makes it work is not really the mystery. It is the people. Four friends with everything between them: magical science, social charm, sheer force of personality, and one ghost who is far too dignified for the cat ears he is permanently stuck with. They used to be close. Then life got in the way. Now a serial killer is pulling them back together, and they have to figure out how to be a team again while they are at it.
But the real heart of the book is Mallory and her fibromyalgia. This is not token representation. It is woven into everything: her relationships, her self-worth, her fear of being a burden. Watching her slowly learn to ask for help, and watching her friends slowly learn to offer it better, is quietly moving. It elevates the book well beyond standard cozy fare.
The queer representation deserves a mention too, because of how unremarkable it is. Queer characters everywhere, they/them pronouns in casual use, and not a single plot point made of any of it. It just is. That normality is its own kind of lovely.
What I genuinely enjoyed was how the investigation blends magic and science rather than pitting them against each other. Forensic magic sits comfortably alongside more grounded analytical thinking, and that combination is fun to follow. The mystery itself is the weakest part though. The detective work is not exactly sharp, and the solution arrives later than your own suspicions probably will. A niggle more than a dealbreaker, but worth knowing going in.
What keeps it together is warmth. These four have history, distance, and then a murder pulling them back together. They are not a perfect team yet. They are working on it. Rebuilding something you almost let go of, carefully and with a lot of miscommunication along the way, is where the book quietly wins.
Funny and a little melancholy, like finding an old friendship bracelet at the back of a drawer and realising you still want to wear it. The mystery may not dazzle, but the friendships absolutely do. Come for the tagline, stay for the found family being slowly, messily rebuilt.
