The venomous serpent

The brass in the Derbyshire village church depicts Sir Humphrey and Sybil de Latours. Strangely, despite the clear detail elsewhere, the face of Sybil is obliterated. However, Sally Fenton takes a rubbing to hang in the bedroom. But at night, in the moonlight, static objects begin to move - and writhe. The rubbing takes on a life of its own. Soon life in the village becomes a nightmare, and Sally and her partner are powerless to stop the evil spreading.
