Step into the world of the Cthulhu Mythos in this mystery game set in 1920s America, where you and your fellow agents of the Bureau of Investigation work to uncover supernatural threats inspired by the writings of H.P. Lovecraft. As a cooperative detective game, players team up to investigate five peculiar cases—each one strange enough to test your resolve. Based on the rules of Sherlock Holmes Consulting Detective with some new investigative mechanics, it offers a fresh challenge for fans of that series while remaining accessible to newcomers. You'll explore locations like Boston and Arkham, follow leads, interview witnesses, and piece together clues across five highly variable cases that blend twists and new gameplay elements. Designed for 1 to 8 players ages 14 and up, each session typically lasts between 2 to 4 hours.
