Dominic Manton is the second son of the Viscount Rathmoor. When his father dies, his older brother, George, becomes the Viscount. Immediately, George burns the codicil that includes their half-siblings and their mother. George then cuts off Dom's allowance and stops paying for his education as a barrister. Dom has to get a job as a Bow Street runner and can't support his fiance, Jane Vernon. Dom gets Jane to break up with him by kissing her cousin Nancy. Thirteen years later, George has died and Dom is now the Viscount. Nancy was married to George and is living in the dowager house when she disappears. Jane (who is finally getting married) is convinced that something bad has happened to Nancy. Dom had an agency called Manton's Investigations, AKA the Duke's Men, so Jane convinces him to help
This is the fourth in "The Duke's Men" series. I loved how it tied in to the other novels but was able to stand by itself. The characters of Dom and Jane and well written. I thoroughly enjoyed this novel.
I received this book as an ARC from NetGalley and the publisher in exchange for an honest review.
