'IT'S A CRIME STORY WOUND UP IN SUPERNATURAL, NERVE-JANGLING CREEPINESS. BE WARNED, YOU'LL BE PEERING UNDER THE BED BEFORE YOU SWITCH OUT THE LIGHT!' PETERBOROUGH TELEGRAPH

Fifteen years ago, 29 Barley Street in Menham, south London became notorious as the scene of alleged poltergeist activity and then as a crime scene with the death of young Holly Wasson. The shadow cast by this episode is still felt in the town, and among the gang of friends who were caught up in the tragic events. That shadow looms larger than ever when one of the group dies in horrific and strange circumstances.

Matt Hunter, former church minister and now university professor, is called in to advise the police on the possible ritualistic elements of the death. And he is forced to ask himself, are forces beyond the grave at work or is a flesh-and-blood killer at large?
