The Cat Caliban series by D.B. Borton follows Catherine “Cat” Caliban, a grandmother who decides she is not done with life and becomes a private investigator. The series started in 1993 with One for the Money and uses a numbering system in the titles that runs from one through eleven. Two Points for Murder, Three Is a Crowd, Four Elements of Murder, and so on give each book a number-based hook while Cat tackles a new case.
The series has had an unusually long publication history, with early entries in the 1990s, a few in the 2000s, and a return in the 2020s with Nine Lives, Eight Miles to Death, Ten Clues To Murder, and Eleven Hours To Murder. Cat herself ages through the series but never loses her sharpness or her willingness to get into trouble. The books are cozy mysteries with a distinct voice, built around a protagonist who proves that detective work has no age limit.
