The Secret Adversary

2017 Reprint of 1922 Edition. "The Secret Adversary" is the second published detective fiction novel by Agatha Christie, first published in January 1922 in the U.S. by Dodd, Mead and Company. The book introduces the characters of Tommy and Tuppence who feature in three other Christie novels and one collection of short stories; the five Tommy and Tuppence books span Agatha Christie's writing career. The Great War is over, and jobs are scarce. Tommy Beresford and Prudence "Tuppence" Cowley meet and agree to start their own business as The Young Adventurers. They are hired for a job that leads them both to many dangerous situations, meeting allies as well, including an American millionaire in search of his cousin. Reviews were generally positive on this adventure, which manages to keep the identity of the arch-criminal secret to the very end.
