Call of Cthulhu: Canis Mysterium + complimentary PDF
"Constable Clark of Coldwater Falls, was desperate for attention. He'd been in touch with every sanatorium and hospital from New York to Boston and there's not an empty bed to be found since the stock market crash last year. They're full to brimming with suicidal businessmen and investors. He's holding a man in his jail exhibiting some rather...extraordinary behaviors. The delusion is complete and total; he walks on all fours and he won't speak a word. They say he even eats out of a bowl and refuses utensils! Not a shred of human behavior left in him."
Canis Mysterium is an adventure scenario for the Call of Cthulhu roleplaying system designed to be played in one or more gaming sessions. This scenario is suitable as an introduction to a new campaign or can easily be worked into an established storyline. As written, this adventure is set in and near Arkham of October 1930. In "The Werewolf of Coldwater Falls", the investigators are called upon to research the strange psychology behind a man exhibiting canine behaviors, discovered with the shinbone of a missing girl dangling from his maw.
Several scenario seeds are offered to keepers who wish to expand and continue the events of this gaming adventure, perhaps giving birth to a brand new campaign or providing handy subplot sessions to pre-existing campaigns. If new characters are created for this scenario we suggest Arkham, Massachusetts as home, and ties to Miskatonic University (particularly the Psychology department).
