Halloween in Essex, and things are going well for the writers on the Mystery and Suspense course at old Ratchette Hall. Things however take a turn for the downright nasty when early on All Saints Day the course administrator is discovered dead in the hall. Lips drawn back, eyes wide open, his face a mask of utter terror, it looks to all intents and purposes that Graham has been scared to death. When he is found to be clutching a cold stone finger the writers are thrown into confusion and fear, convinced the long dead knights have claimed his soul.
But how could the marble effigies have come back to life on Halloween? And why would anyone, dead or alive, want to kill mild-mannered Graham?
There is only one way to get to the bottom of the mystery and the Essex Witch Museum investigators are quickly drafted in.
Very soon, however, Rosie and Sam realise not everything, and everyone are what they seem at Ratchette Hall, appearances can be deceiving, someone certainly has a grudge. As their investigation progresses they find more questions than answers: who is making the unearthly howling noises late into the night? What is the strange glimmering glimpsed in the woods about the Hall? Why is one of the church crusaders missing a finger? And what of the enigma of the ancient empty tomb?
When another one of the writers turns up dead Rosie and Sam realise strange forces are at play. The pair must use their experience of folklore, mystery and magic as well as their wits to solve the mystery before the body count grows.
