Deep in the woods, something is stirring. When Miss Catherine Symonds arrives to take up a position as governess at remote Locksley Abbey in the foothills of the Black Mountains, where England bleeds into Wales, she is apprehensive. It is not the echoing, near empty house with its skeleton staff that frightens her, nor the ancient woods that surround the Abbey or even the dogs that the owner, Sir Rowland, encourages to stalk the grounds, baying for blood. It is Catherine herself who fears scrutiny: her reference and very identity are fraudulent. She is travelling in disguise to investigate the fate of the last governess at the house, who took her own life out in the woods. For that governess was Catherine’s own sister, but until now she had believed Emily had died many years before, when they were just children.
