Halloween in Essex, and things are going well for the writers on the Mystery and Suspense course at Ratchette Hall. Things, however, take a turn when early on All Saints' Day the course administrator is discovered murdered. The Essex Witch Museum investigators are quickly drafted in. As Rosie Strange and Sam Stone's investigation progresses they find more questions than answers: who is making the howling noises late into the night? What is the strange glimmering glimpsed in the woods? Why is one of the church crusaders missing a finger? And what of the enigma of the ancient empty tomb? When another writer turns up dead, the pair must use their experience of folklore, mystery and magic to solve the mystery.
