On the dawn of All Soul's Day, the body of a successful Bath businessman is found in a shallow grave in the shadow of the Glastonbury Tor. The detective duo's first suspect is local artist Hector Ingham, although McDonald can't help but be suspicious of the man who found the body, the mysterious Martin Silver - IT consultant by day, medium by night - who claims to be able to speak to the dead. As increasingly cryptic clues come to light, one name keeps reoccurring in paper trails, credit card statement and on the lips of witnesses…that of Dodds himself.
