As the couple infiltrates the small, tight-knit group of guests, they quickly realize that everyone has secrets, and no one can be trusted. With Britain’s safety at stake, they must unmask the traitors before it’s too late—but the enemy is always one step ahead. Can Tommy and Tuppence outwit Nazi spies and expose the truth, or will they fall victim to a dangerous conspiracy?
