"Two young adventurers for hire. Willing to do anything, go anywhere. Pay must be good. No reasonable offer refused."

A mysterious man hands over important treaty documents to a young woman aboard a ship, which sinks while crossing the Atlantic. Five years later, an American millionaire searches for his missing cousin, his only photograph of her taken by a man posing as a Scotland Yard inspector. The big questions that everyone is asking—where is Jane Finn? And what happened to the treaty papers? Amateur sleuths Tommy and Tuppence are on the case!

The Secret Adversary takes our main characters on a wild ride through the world of espionage, conspiracy and international intrigue in post-WWI London. Get to know Agatha Christie's dynamic detective duo in the first of five Tommy and Tuppence mysteries.
