Despite their best efforts, Melody and Rat found themselves powerless to prevent the crisis in Morocco from spiraling out of control, threatening to ignite the powder keg of tensions between Germany, France, and Britain.

With the specter of war looming, Britain is determined to expand its influence across Europe. After the Agadir Crisis, the preservation of Dutch neutrality, crucial for Britain’s access to Dutch ports, becomes an even more pressing concern. Rat, the new Secret Service Bureau operative, is dispatched to Amsterdam on a mission of the utmost importance- to untangle a puzzle that could decide the fate of Dutch neutrality.

Despite her significant contributions to her brother’s previous cases, Melody is frustrated; Rat is still not convinced that she should continue to be involved and is even trying to persuade Melody to return to London. To add to her frustration, the handsome yet exasperating Conte Alessandro Foscari insists on travelling with them.

Will this be Melody’s last Continental Caper, or will she solve The Amsterdam Enigma?
