The Jacobite story was one of history's longest-running spy sagas. Adherents of the exiled branch of the house of Stuart after the Glorious Revolution of 1688, the Jacobites sought the restoration of James II. In Jacobite Spy Wars, Douglas untangles the details of this complicated intelligence war that involved people from Sussex smugglers to Highland clansmen. Across Europe moles dug for secrets at every court -- kings, ambassadors, soldiers, cardinals, and royal mistresses all participated. Douglas exposes the intricacies of this war, the incredible range of its influence, and the defeating consequences.
