Where ghosts tread, black feathers fall... When Annie marries widower Edward Stonehouse and arrives at Guardbridge, his estate on the Yorkshire moors, she thinks she has finally put darkness behind her. She is mistaken. Edward's sister, Iris, still lives in the family home. A taxidermist and medium, she urges Annie to watch out for black feathers - claiming that they mark the spot where a spirt has visited. At first, Annie dismisses her warnings. But, before long, she begins to feel haunted. What exactly happened to Edward's first wife? Why is Iris so disturbed? And should Annie really be watching for signs from the dead - or is she the one being watched?
