From the brilliant pen of Agatha Christie comes the first novel in her Tommy and Tuppence mystery series featuring the beloved sleuthing duo—now a movie on both Acorn TV and PBS.

Tommy and Tuppence are young, in love… and flat broke. Restless for excitement, they decide to embark on a daring business scheme: Young Adventurers Ltd.—"willing to do anything, go anywhere." But they get more than they bargained for when their first assignment for the sinister Mr. Whittington draws them into a diabolical conspiracy.

It isn’t long before they find themselves plunged into more danger than they ever could have imagined—a danger that could put an abrupt end to their business…and their lives.
