The Brother Cadfael novels of Ellis Peters, created a massive following of readers and spawned a whole new genre that was to become the biggest growing genre in new fiction. The Medieval Mysteries RPG is designed to emulate the medieval detectives like Crowner John, Hugh Corbett and Owen Archer, found in the works of Bernard Knight, Paul Doherty and Candace Robb.
This game has been published by the same author in two very different systems, and with slightly different names: Medieval Mysteries (1PG) and Medieval Murder Mysteries (d20).
