In the early 1970s, Tim and Abi, a pair of precocious twins obsessed with macabre subjects, fake a ghost photograph in order to scare a schoolmate, Janice Tupp. The prank succeeds beyond their expectations, and Janice faints in class at school, cutting her head. Terrified that they'll get into trouble, Tim and Abi invite Janice to their home and show her how the picture was faked. Janice, however, insists they have, in fact, taken a real photo of a ghost, "Or will have done, soon." The second half of the book follows the adolescent Tim, a few years later, as he joins a group of other teenagers in a psychic experiment at an old house in Suffolk. Reception
