One morning before dawn at her regal country estate, Lady Lavinia Truelove is crushed to death by a horse. Classified as "death by misadventure," this appears a gruesome accident, but Scotland Yard detective Joe Sandilands suspects foul play—a misgiving he is struggling to separate from his personal grievances toward Sir James Truelove, who is Lady Lavinia's widower and the influential academic patron of Dorcas Joliffe, whom Joe one day hopes to marry. As Joe's investigation yields surprising secrets about one of England's most powerful families, he discovers how little he knew about not only the gilded lives of the moneyed but also his relationship with Dorcas. Is Joe prepared to risk a future with the girl he loves to uncover the truth behind Lady Truelove's death?
