Bumps in the Night is a collection of five new scenarios for the Call of Cthulhu Roleplaying Game. These scenarios break the mold in that the horrors the players face are not drawn from the Cthulhu Mythos of H.P. Lovecraft, but instead these terrors are drawn from folklore and mythology. Inside you will find vengeful revenants, hungry undead, Sumerian Demon-worshipping cults, malevolent mummies, and poltergeists haunting the body of a crippled girl!
