The Amsterdam Enigma: An Edwardian Spy Mystery (Paperback) (ISBN-13: 9798991919227)

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

With the spectre 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.
