The gripping new psychological thriller from Joanne Harris, to follow her bestselling Gentlemen & Players and Blueeyedboy. Perfect for fans of Claire Mackintosh, BA Paris, Paula Hawkins and Tracy Chevalier. After thirty years at St Oswald's Grammar in North Yorkshire, Latin master Roy Straitley has seen all kinds of boys come and go. But every so often there's a boy who doesn't fit the mould. A troublemaker. A boy with hidden shadows inside. A new broom has arrived, bringing Powerpoint, sharp suits and even sixth form girls to the dusty corridors. But while Straitley does his sardonic best to resist this march to the future, a shadow from his past is stirring. A boy who even twenty years on haunts his teacher's dreams. A boy capable of bad things.
