In this small but perfectly formed collection of supernatural short stories, Sophie Hannah takes the comforting scenes of everyday life and imbues them with a frisson of fear, then a gust of terror. Why is a young woman so unnerved by the presence of a visitors book in her boyfriend's inner-city home? And whose spidery handwriting is it that fills the pages? Who is the strangely courteous boy still lingering at a child's tenth birthday party when all the parents have gathered their children and left? And why does the presence of a perfectly ordinary woman in a post office queue leave another customer pallid and sweating with fear?

Beware what you open this Christmas!
