Horror's Heart is an adventure campaign published by Chaosium in 1996 for the 5th edition of the horror role-playing game Call of Cthulhu. Description Horror's Heart is a Call of Cthulhu campaign set in Montreal in 1923 that is divided into six chapters, each of which takes up one day of game time: Day 1: The American investigators are travelling to Montreal via train to Montreal at the behest of a mutual friend, Father McBride. During the trip, the investigators have an opportunity to foil the kidnapping of actress Céline Lavoie, who is travelling to Montreal to attend the funeral of her grandfather Lucien. Once in the city, the investigators meet Father McBride, who reveals that during an excavation under the church, a tomb containing a mummified body and a strangely well-preserved heart encased in a reliquary were discovered. The investigators meet Céline for dinner, and become involved in a fight, where they are aided by the sudden appearance of an unnaturally intelligent dog. Day 2: The investigators attend the funeral of Céline's grandfather. Afterwards, they are asked to lift a curse Lucien laid on his entire family. Day 3: The mummy is stolen, and Father McBride goes missing. The investigators have a chance of lifting the Lavoie curse. Days 4 & 5: The investigators discover two ancient and evil rival cults operating in the city. Day 6: The investigators must prevent an Elder God from being resurrected.
