What’s cozier than a cozy mystery that takes place in a library? A cozy mystery falls in the mystery / crime genre. Some of the traits of a cozy mystery are the violence taking place off-page, a cast of quirky supporting characters, and an amateur sleuth. In our case today, we are looking at cozy mysteries where the crime-solver’s day job is working as a librarian!
