The last thing Lady Katherine wants is to take the matchmaking job for Mrs. Burwick, whose daughter, Prudence, clearly does not want to be matched . . . until she realizes it provides her the perfect cover to investigate the string of robberies that have been taking place in the holiday town of Bath.
Katherine, her loyal maid, Harriet, and her tenacious pug, Emma, soon find themselves knee-deep in troubled waters as they try to piece together the baffling clues to reveal the truth. To further complicate matters, Katherine's investigation is impeded by the incompetent detective hired by the Marquess of Bath to flush out the burglar.
Now Katherine must juggle advising Prudence on how "not" to land a duke while she dives into the investigation in the hopes of narrowing down the suspects without making waves amongst the aristocracy, some of whom are her primary suspects.
When the burglary attempts turn violent, Katherine must take drastic measures to ensure her detective career isn't all washed up before it even gets started.
