The story of Emily Fox-Seton, now Lady Walderhurst, continues after her marriage to the Marquis of Walderhurst. She has fallen deeply in love with her husband. After Emily is introduced to her husband's presumed heir, her compassion for his pregnant wife moves her to insist that the couple be installed on the country estate. She is oblivious to the heir's sense of entitlement and the threat she poses to his inheritance as a woman of childbearing years who could provide a son to inherit the title and estate. Danger threatens when the Marquis leaves Emily alone with the Osborns while he goes to India on an extended business trip.
