The Secret Adversary. A Tommy & Tuppence story, by Agatha Christie || Audiobook by LA CASE Books || Murder Archives Vol. 6.

The Secret Adversary introduces Tommy Beresford and Tuppence Cowley, two young friends who form Young Adventurers Ltd. and advertise themselves as “willing to do anything. Go anywhere…no reasonable offer refused.”

Their first job leads them into a series of increasingly dangerous situations involving international spies, a society beauty, a Russian count, the wreck of the Lusitania, an amnesia patient, an American millionaire, and a fiendishly clever arch-criminal known only as “Mr. Brown.”

By the time the dust settles, all the puzzle pieces have been fitted together—and the young couple have realized their feelings for each other and have become engaged. Tommy and Tuppence were the characters Christie most enjoyed.
