Kate Shakleton's sterling reputation for courageous sleuthing attracts the attention of the venerable Lady Coulton. Hidden in her past is a daughter, born out of wedlock and given up to a different family. Now, Lady Coulton is determined to find her and puts Kate on the case. But as Kate delves deeper into Lady Coulton's past, she soon finds herself thrust into a scandal much closer to home. When the body of the respected Horatio Potter is found in the Leeds Library basement, the quiet literary community is turned upside down with suspicions, accusations and - much to Kate's surprise - the appearance of a particularly intelligent Capuchin monkey.
