This is a well-written and even exciting story, but it only gets two stars from me because I found the main character rather irritating. Suzie is a dedicated genealogist, who gets the chance to post on the internet some data from a local manor house. Suzie gradually accepts her son's theory that the manor house, and its owner, are part of an unpleasant and dangerous plot. But she's obsessed with proving that she's related to the lady of the manor, and continues to search even after she realizes that she and her family are in danger.
