Regency Cthulhu: Darkness and Decorum in Jane Austen’s England is a historical sourcebook for the Call of Cthulhu roleplaying game. Set in the early Regency period (circa 1813), it describes the fictional town of Tarryford in Wiltshire, England, as well as presenting two scenarios designed to introduce players to both the time period and the town’s mysteries.

Suitable for use with both classic Call of Cthulhu and Pulp Cthulhu rules, players take on the roles of budding Regency investigators, be they members of the gentry or the working classes. Together they uncover the dark secrets at the heart of Tarryford; horrors that have lain dormant for many a year but now seek to burst forth into England’s green and pleasant land.
