The Secret Adversary

Two out-of-work young friends, Tommy and Tuppence, advertise themselves as adventurers for hire and are plunged into a web of espionage, a missing document, and a shadowy criminal mastermind. Lighter and more thriller-paced than Christie’s Poirot mysteries, it blends romance, danger, and wit. It introduced the beloved Beresford duo who would return across her career.
