The Sassoon Files
A collection of four scenarios and campaign resources for Call of Cthulhu 7th Edition and GUMSHOE, set in 1920s Shanghai. Players investigate supernatural threats amid espionage, organized crime, political conflict, and the city’s competing international factions. The modular scenarios can be played independently or linked into a campaign through recurring locations, characters, threats, and themes. Adventures involve ancient Daoist rituals, alien spirits, triad intrigues, occult schemes, lost cities, and other elements of Shanghai’s hidden Mythos history.
