A duke's manor house party. Feuding spies. Stolen jewels. A ducal divorce. What could go wrong? An invitation to the country estate of the Duke of Bamford seems a welcome escape from London intrigues for former spies Malcolm and Mélanie Rannoch. They've just survived one of their most challenging and personal investigations ever. But the ducal house party is not quite the bucolic idyll they hoped for. Anthony and Henrietta Southcott, Duke and Duchess of Bamford, plan to announce their shocking plans to divorce to their friends and grown children. The ensuing scandal alone is enough to shake the Regency beau monde, but stolen treasure from the English Civil War, a secret passage, and stolen papers from the far more recent Napoleonic Wars plunge the Rannochs right back into the dangers they thought they had left behind. Soon they're racing to untangle a fiendish plot and prevent a disaster that would prove far more deadly than divorce...
