Lord Alexander Montgomery Scott was caught in a compromising position with his childhood friend Emily Cartwright. Her father forced them to marry and his father sent Alex abroad and made Emily's life purgatory. For five long years the status quo remains unchanged, until Alex's siblings start dying and his father, the very powerful Duke of Northumberland has a seizure. Alex is summoned home, but due to the war with the French, his father has passed away before he can reach England, leaving Alex as the next Duke. Determined to shoulder his responsibilities, at last, Alex sets about reconciling with his wife, but in his efforts to make things right, he only makes them a target for whoever is trying to kill them. Emily, angry at her treatment, has a secret for The Duke's Son.
