A missing woman, a dangerous secret, and two young adventurers caught in a conspiracy that could change everything.



After the turmoil of the First World War, Tommy Beresford and Prudence "Tuppence" Cowley are young, ambitious, and searching for excitement. Instead, they find themselves drawn into a mysterious and dangerous mission involving a missing woman, a hidden secret, and a powerful enemy operating behind the scenes.



What begins as an opportunity for adventure soon becomes a race against time. As Tommy and Tuppence follow a trail of clues, they encounter deception, false identities, unexpected dangers, and a conspiracy whose true purpose remains carefully concealed.



The Secret Adversary introduces one of Agatha Christie's most entertaining detective partnerships: the energetic and determined Tommy and Tuppence. Unlike Christie's traditional murder mysteries, this novel combines suspense, espionage, adventure, and mystery to create a fast-moving story filled with twists and intrigue.



First published in 1922, the novel showcases Christie's remarkable ability to keep readers guessing while building tension from one revelation to the next.



Follow Tommy and Tuppence into a world of secrets and danger—and uncover the truth behind the mysterious adversary waiting in the shadows.
