Drummond Castle, home of staunch Puritan Silas Drummond and his beautiful wife, Elizabeth, has been besieged by Royalist forces. In order to spare her husband's life, Lady Elizabeth has agreed to spend the night with the commander of the hated King's Men.
Second in command Charles Trethveyan has other ideas. He's planned this moment since Elizabeth chose to marry Silas eight years before. When Elizabeth discovers that her former Cavalier lover has taken the place of his superior, she must decide whether Charles is motivated by love or revenge. Either way, her response will have devastating consequences.
