Elinor, the widow Lady Standon, needs to find a husband and fast. Her stepfather is threatening to marry off her younger sister to a despicable old man, so Elinor needs a powerful husband of her own—namely, a duke—to stop him. Much to her dismay, Elinor discovers that there are only three eligible dukes currently residing in London. One of them will just have to do. To this end, she enlists the aid of a man she assumes is a solicitor, but is in reality James Tremont, the ninth Duke of Parkerton. From the day of his birth James Tremont has been brought up to be as high in the instep as they come. But the lofty ways that have also furnished him with a secluded and protected life are shattered the day he is sent on an errand to the house on Brook Street, wearing the plebian clothes of his brother. Suddenly stripped of his ducal trappings, James discovers a rare sort of freedom. And even though he knows he should correct the lovely and elegant Elinor’s mistake when she hires him as a common man of business, he wonders if he could win her over while being, well, ordinary.
