It is 1711, and the Ulster-Scots community in a remote corner of Ireland is in turmoil. A pretty young newcomer is accusing one woman after another of witchcraft. But Ellen, the serving girl in the house where the visitor is staying, is loyal to the family - and over-fond of her master. Yet she knows that Knowehead is a house like no other. And so she watches and ponders, as a seemingly normal girl claims she is bewitched - as a - community turns against eight respectable women and as malevolent forces unleashed more than half a century earlier threaten a superstitious people beyond their understanding. Martina Devlin has fictionalised a compelling episode from history, transforming it into a spine-chilling tale.
