Miss Annabelle Honeycote is a talented seamstress who is responsible for the success of London's busiest dressmaking shop, favored by the ton's most fashionable young ladies. However, her salary isn't commensurate with her skills and her mother's recent illness has made it necessary for this gently-bred young woman to resort to criminal behavior. Owen Sherbourne, the Duke of Huntford, is determined to see his two younger sisters not just accepted by society but also make brilliant matches. A challenge considering Olivia is headstrong and Rose has barely spoken a word since their scandalous mother ran off to the continent. But in the two years since he suddenly inherited the dukedom, Owen has worked tirelessly to restore his family's fortune and illustrious name and he will not accept defeat. So when Owen receives an extortion note asserting one of his sisters is hiding a secret that would destroy her reputation, he takes immediate steps to apprehend the blackmailer himself. When he realizes the villain is not a hardened criminal but a frightened young woman-in fact, the little mouse whose dresses are in such demand-he proposes a deal that Annabelle cannot refuse.
