That is when his world collapses, as the captain of that regiment returns with the news that a naked man has been found in his wife's bed. Heartbroken, he returns home to confront her, hoping for an explanation, but she admits her guilt. David leaves for London, having appointed guards to be sure she does not leave the grounds, and never expects to return.
Three years later he receives a letter from his wife, Catherine, telling him she is dying and begging him to go to her, as she needs to reveal the truth about the other man and the daughter David always supposed to have been fathered by that man.
Catherine knows he will not refuse her dying wish, but what can the truth be, if not that she had a lover in her bed? The idea of losing her for good tears him apart, despite her betrayal, but he needs to find the courage to see her on her deathbed and learn the truth, for the sake of the woman he still loves.
