The Aunt Bessie Cold Case Mysteries are a spinoff of Diana Xarissa Dunn’s popular Isle of Man Cozy Mysteries. In this series, Aunt Bessie turns her attention to historical unsolved cases on the Isle of Man. Each book is titled “The [Surname] File,” running alphabetically from The Adams File (2021) through The Snow File (2026).
The cold case format gives Bessie different kinds of mysteries to solve, often involving events from decades past. The series maintains the cozy tone and Isle of Man setting of the original Aunt Bessie books while adding a historical research element as Bessie digs through old records and interviews aging witnesses.
