When a mysterious list of names is found in the shoe of a dead woman, one of those named, Mark Easterbrook, begins an investigation into how and why his name came to be there. He is drawn to The Pale Horse, the home of a trio of rumoured witches in the tiny village of Much Deeping. Word has it that the witches can do away with wealthy relatives using the dark arts alone, but as the bodies mount up Mark is certain there has to be a rational explanation. And who could possibly want him dead?
