From the New York Times bestselling author of the Addison Holmes Mystery Series...

Meet Scarlet Holmes, a fiery young woman from Whiskey Bayou, whose sharp mind and fearless spirit catapult her from a small-town outcast to a daring spy for the Allied Resistance. Sent to Marseille in 1940 under the guise of a makeup saleswoman, Scarlet, codenamed Bouncing Betty, navigates the Nazi-occupied city with cunning and charm. Her mission: infiltrate the Gestapo's inner circle and uncover secrets that could turn the tide of war.

When a chance encounter with the enigmatic Henry Graham, the Alliance's most infamous operative, sparks both danger and desire, Scarlet finds herself entangled in a deadly game of trust and betrayal. As she seduces the ruthless Major Wagner to gain access to critical intelligence, Scarlet must outwit double agents, evade capture, and confront the devastating truth about those closest to her. Armed with her wits, a hidden knife, and an unyielding resolve, Scarlet's every move could mean salvation—or death—for the innocent lives hanging in the balance.
