The full title is Casting the Runes: Occult Investigation in the World of M. R. James; and the title really does say it all. “Casting the Runes is a roleplaying game based on the works of M.R. James, the father of the modern British ghost story, and uses the GUMSHOE system for investigative RPGs. The unique character of James’s stories, and his own personality, inspire the game.” It’s Edwardian-Era intangible horror, in other words. I picked it up because ghost stories sound like they’d work well in GUMSHOE’s system, and because they’re throwing in the PDF along with the print book for free. I’m down with that.
