When Roberto Fratelli—the meanest man in Marthasville, Virginia—sells his antiques store to the newly elected mayor's mom, Camille Benson, local merchants are overjoyed. Camille's best friend, Opal, tells her about finding a 1756 letter to George Washington hidden under a chair in the shop. Returning to retrieve the cache, they find Roberto's lifeless body on the floor and no letter. Making her first outing as a sleuth, Camille prepares to delve into Roberto's past, and she knows she might become the latest knock-off.
