In the English village of Kurland St. Mary, few things are worse than having one's reputation besmirched. A struggling marriage is one. Murder is another . . .

Three years have passed since Major Sir Robert Kurland and Lucy Harrington, the rector's daughter, became husband and wife. Having established a measure of contentment among the local gentry, the couple lately have found an unsettling distance grown between them. But when the small-village peace is disrupted by an anonymous letter accusing Lucy of witchcraft, her as yet unfulfilled desire to be a mother becomes the least of her worries, especially after she learns she is not the only one to have received such a malicious letter. Speculation only escalates when the village schoolteacher, Miss Broomfield, is discovered murdered at her classroom desk. Was the unlikeable teacher the letter writer, and if so, who killed her and why? Despite her husband's objections, Lucy offers to help out at the school until a replacement can be found, hoping the children might inadvertently reveal a clue, but by doing so she may be putting her own life at risk . . .
