An aristocratic sleuthing duo seeks a killer in Regency London's back alleys and drawing rooms.
The Earl of Wrexford and his wife, Charlotte, have had a great deal of experience with mysteries, and their wards, Raven and Hawk, former street urchins with a scientific bent, are always up for a new adventure. So when their dog turns up a body floating in Hyde Park's lake, the Serpentine, their curiosity is piqued. The late Jeremiah Willis—whose father was a formerly enslaved man from Virginia and mother a White Englishwoman—was an inventor of note, and Wrexford and Charlotte soon learn that his orphaned nephew, young Peregrine, stands to inherit a large estate from the other side of his family. But Peregrine’s Uncle Belmont, who turns out to be married to Charlotte's brother's sister-in-law, resents the fact that his older brother’s late-in-life son will inherit the estate he'd long regarded as his. The boys soon become friends, and Peregrine joins the Wrexfords in London, where a government representative asks Wrexford to find the person who killed Willis and stole the design for a revolutionary rifle and, of course, to recover the papers setting forth that design. The representative, who’s not above a little blackmail, hints that his higher-ups know that Charlotte is the gadfly illustrator A.J. Quill, who often criticizes government policy. In honor of a celebration of peace, London is awash in visiting leaders and royals, including the czar of Russia. Once Wrexford learns that there’s to be a secret auction for the papers, he determines with the help of his family and friends to find them first and uncover a killer.
A charming, action-packed mix of historical mystery and Regency romance.
