Set in 1715, the story follows Jonas Flynt—a gambler, thief, killer, and reluctant spy—who works for the shadowy Company of Rogues. Tasked with recovering a secret will said to name James Stuart, Queen Anne’s half-brother, as the rightful heir to the British throne, Flynt must outwit rival agents and deadly enemies. His dangerous mission takes him from the crime-ridden streets of London to the tense, divided city of Edinburgh, where political unrest simmers and personal demons await. As he digs deeper into royal secrets and his own troubled past, Flynt becomes entangled in betrayals, riots, and long-buried family revelations—with the fate of the British crown hanging in the balance.
