This book centers on Adam Salton who is contacted by his great uncle in England, for the purpose of establishing a relationship between these last two members of the family. Adam travels to Richard Salton's house in Mercia, and quickly finds himself in the center of some inexplicable occurrences. The new heir to the Caswall estate, Edgar Caswall appears to be making some sort of a mesmeric assault on a local girl. And, a local lady, Arabella March, seems to be running a game of her own, perhaps angling to become Mrs. Caswall. There is something strange about Lady March, something inexplicable and evil.
