'Peaceful' is the most common entry in the visitors' book of fifteenth-century St Michael's Church, with its glorious angel roof and its medieval Doom painting. But outside the church, and under the surface, peaceful is scarcely the word for the tiny Norfolk village of Walston. The Rector's new bride, Becca Thorncroft, is receiving phone calls so unpleasant that her very sanity is at stake, and the newest residents of Walston, Gillian English and Lou Sutherland, are not exactly welcomed with open arms. Then sudden, gruesome death shatters even the outward peace of Walston. Fortunately for Father Stephen Thorncroft, his friends Lucy Kingsley and David Middleton-Brown are on hand to sort through the tangled relationships and dark motivations of the villagers, uncovering more than they bargain for. But it is not until a little girl goes missing that the final, deadly pieces fall into place in their search for the evil angels among them.
