S01E01 The Secret Adversary, Part One
Tommy and Tuppence have a chance encounter on a train with an agitated young woman who suddenly disappears and never returns to her seat.
Tommy has finally found the missing scientist, but they're both being held against their will by M, and still none the wiser as to who N is.
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.
