'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 away from the church, and beneath the idyllic veneer, the tiny Norfolk village of Walston is anything but harmonious.

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 any remaining semblance of serenity.

Fortunately for Father Stephen Thorncroft, he is able to enlist the help of his friends Lucy Kingsley and David Middleton-Brown to unravel the tangled relationships and uncover the dark motivations of the villagers.

As the investigation proceeds, they stumble on more than they'd bargained 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'.
