Ann Colbert–recently married to the charming Glenn Stacey–is struck by a sudden blow: her father dies, leaving her alone in Boston. After receiving a desperate, half-finished letter from her childhood nurse, Miss Lucy, Ann rushes to fly to her childhood home in Devon. There, she meets the cousins she’d never known: the Thornes of Valicombe, a crumbling old mansion. After learning of Miss Lucy’s sudden death just days before, Ann sets herself up in her nurse’s cottage, determined to wait for her husband to arrive. Glenn never appears, however, and Ann finds herself drawn into a terrible intrigue.
