Call of Cthulhu Mansions of Madness Volume One Behind Closed Doors Adventure Book

Open five doors to horror with Mansions of Madness Volume One Behind Closed Doors for Call of Cthulhu. The collection revises two classic scenarios and adds three new investigations centred on troubled homes, hidden occupants and unsettling secrets in the 1920s.

Each scenario works as a standalone adventure, a sidetrack within an ongoing campaign or part of a connected mini-campaign. The varied mysteries include a suspicious local businessman, a supposedly cursed manse and bizarre events at Wellington Manor.

The adventures are suitable for up to six investigators and their Keeper, with each generally taking one to three sessions. This makes the hardcover a natural follow-up for groups that have completed introductory collections such as Doors to Darkness or Gateways to Terror.

This scenario collection requires the Call of Cthulhu Starter Set or the Seventh Edition Keeper Rulebook. Pulp Cthulhu is optional and sold separately.
