The Secret Adversary

A missing document, a dangerous conspiracy, and two young detectives caught in a deadly game.
When Tommy Beresford and Tuppence Cowley become involved in a mysterious search for a missing woman and a vital secret, they find themselves drawn into a dangerous international conspiracy.
Unlike Christie’s famous Poirot mysteries, The Secret Adversary delivers a faster-paced thriller filled with disguises, espionage, suspense, secret identities, and unexpected danger. Tommy and Tuppence bring youthful determination and charm to an investigation that becomes far more dangerous than they ever expected.
With its blend of mystery, adventure, romance, and espionage, this novel showcases another exciting side of Agatha Christie’s storytelling.
Join Tommy and Tuppence on the adventure that launched one of Christie’s most memorable detective partnerships.
