March 1818In the elegant environs of Mayfair, Malcolm and Suzanne Rannoch live a seemingly charmed life. Malcolm, a former diplomatic attaché and intelligence agent, is a rising Member of Parliament. Suzanne is fast becoming one of London’s most sought hostesses. But even their closest friends don’t know that the Rannoch’s marriage is still reeling from the revelation that Suzanne was a French spy when she met British agent Malcolm and that she married him to gather information on British plans. Malcolm and Suzanne are hoping for private time to repair their marriage. But their peace is shattered by a late night visit from a Bow Street runner. The powerful Duke of Trenchard has been found murdered in the study of his St. James’s Square house. And Laura Dudley, governess to the Rannoch children, was standing over the dying duke. Malcolm and Suzanne are convinced the woman they trusted with their children is not a killer. To prove Laura’s innocence, they are drawn into an investigation that will test their wits and the fragile truce between them. But whether or not she murdered the Duke of Trenchard, Laura Dudley is certainly not what she seemed. Revelations about her identity cut dangerously close to Suzanne’s own past. Malcolm and Suzanne realize more is at stake than Laura’s life and liberty. The investigation into the Duke of Trenchard’s murder will either prove the resilience of their bond–or snap it in two.
