Penrose's atmospheric mystery series sends newlywed sleuths, Lady Charlotte and the Earl of Wrexford, beyond the glittering ballrooms and salons of Regency London to untangle a web of international intrigue... Charlotte, now the Countess of Wrexford, would like nothing more than a summer of peace and quiet with her new husband and their unconventional family and friends. Still, some social obligations must be honored, especially with the grand Peace Celebrations unfolding throughout London to honor victory over Napoleon. But when Wrexford and their two young wards, Raven and Hawk, discover a body floating in Hyde Park's famous lake, that newfound peace looks to be at risk. The late Jeremiah Willis was the engineering genius behind a new design for a top-secret weapon, and the prototype is missing from the Royal Armory's laboratory. Wrexford is tasked with retrieving it before it falls into the wrong hands. But there are unsettling complications to the case-including a family connection. Soon, old secrets are tangling with new betrayals, and as Charlotte and Wrexford spin through a web of international intrigue and sumptuous parties, they must race against time to save their loved ones from harm-and keep the weapon from igniting a new war . . .
