Call of Cthulhu – Mansions of Madness Vol 1

Behind every door, a secret. Mansions of Madness: Vol 1 – Behind Closed Doors gathers five scenarios for Call of Cthulhu that take investigators inside the strange houses of the 1920s, from a cursed manse to a Scottish golf club where the renovations are the least of anyone’s worries.

The collection pairs two revised classics, Mister Corbitt and The Crack’d and Crook’d Manse, with three brand-new adventures: The Code, The House of Memphis and The Nineteenth Hole. Each runs in one to three sessions and works as a standalone, a sidetrack in an ongoing campaign, or part of a connected mini-campaign across the decade.

Fully compatible with the Call of Cthulhu Starter Set and the 7th edition rulebook, this 224-page full-colour hardcover is the ideal next step once your players have their first investigation behind them.
