Set in a 1950s Britain rising from the ashes of the Blitz into the grip of a new Cold War, our beekeeping duo stumble into a world of murder, undercover agents and cold war conspiracy. Tuppence is a woman who sees adventure round every corner, throwing herself head first into every mystery with passion and fervour, determined to get to the truth no matter what it takes, much to the dismay of her more cautious husband Tommy.
