Cat Caliban Books in Order

The Cat Caliban mysteries follow Catherine "Cat" Caliban, a recently widowed Cincinnati grandmother who decides that the next stage of her life will involve becoming a private investigator. She has raised three children, become a grandmother, and spent years doing what other people expected. Now she buys an aging apartment building, moves in with her cats, and starts learning the detective trade on her own terms.

Cat is not a polished professional when One for the Money begins. She is practical, curious, impatient with nonsense, and very willing to annoy the police if she thinks they are overlooking someone who deserves justice. Her home, the Catatonia Arms, becomes a base for both her new life and a shifting group of tenants, friends, relatives, and neighborhood regulars who can offer help, advice, or fresh complications.

The setting matters. Cincinnati is not just a backdrop but a working city with distinct neighborhoods, old stories, and people whose lives do not fit neatly into official versions of events. Cat's cases often begin with someone dismissed by others, a death written off too quickly, or an uncomfortable local secret. The mysteries take her from high-school basketball pressure in Two Points for Murder to old political conflicts in Three Is a Crowd, pottery, fire, and Cincinnati history in Five-Alarm Fire, and the troubles facing women on the margins in Six Feet Under.

Cat has plenty of nerve, but she is not alone.

As the series continues, retired police officer Moses Fogg becomes an important investigative partner. Their partnership gives the later books a steadier detective rhythm while keeping Cat's independent streak intact. Seventh Deadly Sin connects the death of a teenage football star to a wider pattern of danger. In Eight Miles High, Cat and Moses investigate threats aimed at former Women Airforce Service Pilots, turning an old wartime disappearance into a present-day risk. Nine Lives brings Cat into another fire, a rescue of kittens, and a mystery rooted in a prominent family's buried past.

These are humorous mysteries, but they do not pretend that every problem is small. Borton uses Cat's blunt observations and the everyday chaos of family, pets, landlords, and neighbors to keep the books lively, while the cases touch on subjects such as homelessness, racism, aging, prison, and the cost of keeping secrets.

Start with One for the Money to see Cat claim a new life and stumble into her first case. The books work best in order because Cat's circle of friends, her work with Moses, and her confidence as an investigator grow from one mystery to the next.
