In 1934, the dying composer Sir Edward Elgar feebly whistled to a friend the theme from his Cello Concerto and said, "If you're walking on the Malvern Hills and hear that, don't be frightened. It's only me." Seventy years later, Merrily Watkins—parish priest and Deliverance Consultant to the Diocese of Hereford—is called in to investigate an alleged paranormal dimension in a spate of road accidents in the Malvern village of Wychehill. There, Merrily discovers new tensions in Elgar's countryside. The proposed takeover of a local pub by a nightclub owner with a criminal reputation has become the battleground between the defenders of Olde Englande and the hard men of the drug world—with extreme and sinister elements on both sides. And as the choral society prepares to stage an open-air performance of Elgar's Caractacus at a prehistoric hill fort, the deaths begin.
