London 1817. In the aftermath of the Napoleonic Wars, Melanie and Charles Fraser have traded the moment-to-moment dangers of the war-ravaged Continent for the glittering world of the British ton. But beneath the shimmering veneer of London society, they discover an establishment that is rotten to its very core.
An assassination and a trail of clues that lead back to the French Revolution itself plunge Charles and Melanie once more into the danger that has always been the common ground in their marriage. As they search for the truth, they find that the answers cut shockingly close to their own friends and family - including the seemingly perfect Honoria Talbot.
