A carved slab on a lonely beach. A beautiful servant girl resigned to live in a crumbling mansion. An army cover-up over wartime experiments. A Victorian cult's depraved rituals.Seven academics face the unknown when they decide to visit a remote Scottish island. Someone is a murderer, somebody doesn't want them to remain, something refuses to let them leave. They need to find out who's responsible for the killing before lust, ambition and jealousy tear them apart, and an ancient conflict robs them of their sanity--and lives.
