Edinburgh, October 1679. Christian Nimmo is arrested and charged with the murder of her lover, James Forrester. News of her impending trial is splashed across the broadsides, with headlines that leave little room for doubt: Adulteress, Whore, Murderess. Only a year ago, Lady Christian was leading a life of privilege and married respectability. What led her to risk everything for an affair? And does that make her guilty of murder? She wasn't the only woman in Forrester's life, and certainly nor the only one who had a motive to kill him.
