Former spy Gabriel d'Aubrigny, the Chevalier de Lesgardes, returns to England with a purse of gold and plans to start a new life—until a highwayman robs him, taking even his horse. Penniless, Gabriel must turn to the enigmatic spymaster, Sir Alaric Fitzwilliam, for work. His mission: to pose as a courtier and unmask a man suspected of using dark magic against the Throne. After stealing from a handsome traveler, Anne Tremaine uses her new fortune to pose as a wealthy widow. While hunting in London society for an old enemy, she meets Gabriel once more. Every encounter with the Frenchman is a dangerous game, for his touch ignites desire—but one slip might send her from his embrace to the gallows.
