Presented here are the first two books of Agatha Christie's beloved 'Tommy and Tuppence' series: 'The Secret Adversary' and 'Partners in Crime,' featuring the exploits of Tommy and Prudence 'Tuppence' Beresford, a pair of young detectives whose investigations ensnare them in a series of international mysteries.

In the first, Tommy and Tuppence are in search of a missing woman who vanished while carrying a secret treaty that could endanger Britain. As they delve deeper, they uncover a web of espionage, political intrigue, and deception led by a mysterious figure known only as 'Mr. Brown.'

Then, in 'Partners in Crime,' the pair are tasked by British intelligence to uncover a secret spy ring. Using a detective agency as a front for their investigations, each case they handle parodies the style of a different famous detective, showcasing Christie's wit and love for the genre.

From missing jewels to mysterious murders, Tommy and Tuppence tackle every challenge with humor, charm, and clever teamwork.

These two books are presented here in their original and unabridged formats.
