Like moths to a flame, people are drawn to Dower House. To see the estate in dappled sunlight, to feel the breeze blown in from the river, is to forever be in love. Among those caught in its spell are James and Nemo Boyce, who quickly buy it, and Professor Harry Harris, who becomes captivated by both the house and its new mistress. But an uninvited guest soon corrupts their paradise, and quickly reveals the dark heart of the home.
