When American heiress Millicent Wright visits the eerie moors of Devonshire, her hunt for a titled British husband turns into a search for a cold-blooded killer. With her prospective husband not yet cold in the grave, Millicent delves into the secret lives of the inhabitants of the sleepy little village of Buckfastleigh. Murder suspects abound, from a spurned lover, a dour sister, and a disgruntled footman, to a retired colonel, a deranged grandmother, and a seemingly simple country doctor. The only one who appears to want to help is the handsome Detective Lockwood. But with the list of murder victims growing longer and her own life in danger, Millicent doesn't know how far she can trust him. Someone or something certainly seems to want her out of the way. Does the infamous curse on the Longbourne brides extend to soon-to-be brides or is someone at Buckfast Hall playing a terrifying and deadly game?
