Emma Dickson has a successful City career and a flourishing relationship. So why does the advertisement for sale of Lizas Cottage, a house she remembers from childhood holidays on the rural Essex coast, turn her well-ordered life upside down with longing? Mike Sinclair is fascinated by the history of the parish, especially the seventeenth century, when Witchfinder General Matthew Hopkins conducted his terrible work. Emma pins her dreams on her move to Mistley - but once there, she is haunted by nightmares, dreams of the past, and of the cottages original owner at the time of the witch-hunt. As the ancient feast of Halloween approaches, an escalating sense of menace threatens to explode into terrifying violence.
