SACRAMENTS OF EVIL is a supplement for the CALL OF CTHULHU roleplaying game, containing "Six Independent Victorian Horror Adventures" set in 1890s England. Some of these are suitable for beginning players and investigators, while others assume some experience with the Cthulhu Mythos. SACRAMENTS OF EVIL integrates background information from Chaosium's CTHULHU BY GASLIGHT supplement, but that book is not needed for play.

(Sacraments of Evil is the third 1890s supplement for Cthulhu, after Cthulhu by Gaslight and Dark Designs.)
