Quicksilver Reading CompanionLouis XIV’s man in The Hague — diplomat, spymaster, and Eliza’s most dangerous adversary.
Who he was
Jean-Antoine de Mesmes, comte d’Avaux (1640–1709), served as French ambassador to the Dutch Republic from 1678 to 1688. His job was to keep the Dutch divided and compliant while Louis XIV expanded French power. He ran intelligence networks, bribed Dutch officials, and reported on William of Orange’s movements. He was good at it.
In the novel
D’Avaux is the primary antagonist in Eliza’s storyline through Books 2 and 3. He recognizes her intelligence and tries to recruit her as an agent; she plays a double game, feeding information to both the French and William’s court. The tension between them is one of the novel’s best sustained conflicts — two people who understand each other’s capabilities, each trying to use the other without being used.
The historical context
D’Avaux’s real diplomatic career tracks closely with the novel. He was recalled from The Hague in 1688 when William invaded England — a disaster he’d tried to warn Paris about. He later negotiated the Treaty of Ryswick (1697). His dispatches, published posthumously, are a primary source for Dutch-French relations in this period.
