A couple with a reputation for crime-solving becomes involved in an odd murder case in 1832 Scotland.
Kiera Gage, better known as Lady Darby, and her husband, Sebastian Gage (An Artless Demise, 2019, etc.), are among the five dozen guests the Duke and Duchess of Bowmont have invited to Twelfth Night festivities at an immense Gothic castle in the Scottish border country. Kiera’s first marriage—the source of the title she'd rather not use—made her both miserable and notorious for executing anatomical drawings for her cruel husband, but she’s more recently gained a reputation as a portrait artist, and the Duchess is her client. Each guest at the ball is given a costume to wear and a role to play; amusingly, the heavily pregnant Kiera is a nun. Although the Duke claims all his children as his own, several of them were actually sired by other men. When his third son, Lord Edward, offers a ghost tour, the Gages are happy to escape the ballroom until the group stumbles upon a dead body in the dungeons. Ravaged by rats and decomposition, the corpse is difficult to identify, but its gentlemanly attire suggests that it may be Helmswick, the husband of the duke's daughter Lady Eleanor, who left for Paris a month ago. The ducal couple beg the Gages to investigate while withholding vital information. Lady Eleanor was unhappy with Helmswick, a man of many secrets and mistresses, and she’s commenced an affair with her first love, the Marquess of Marsdale. After the guests who were not at the castle when the murder occurred are permitted to depart, a disconcerting number of suspects remain behind. Kiera knows she’s touched a nerve when someone tries to push her down a flight of stairs. She and Gage must uncover many family secrets before they can unmask a killer.
Romance, suspense, mystery, and bawdy historical customs add up to a fine read.
