These Old Shades II

In England, Justin takes Leonie to his sister Fanny, who is married to a rather dull but good hearted man, Edward Marling. She has a son. He tells her that Leonie is his ward and not his mistress. Fanny affects shock. Justin tells Leonie she has to learn to be a young lady. He takes her to Avon, his house in Somerset, and trains her in the social graces. He brings in a cousin Mrs Field to be her chaperone. Rupert comes to stay at a nearby house, Merivale Place, and he visits his brother's ward.... and finds her amusing and charming. Justin meanwhile tells Hugh, his friend that he has had a long running feud with the French nobleman, the Comte de St Vire. When he met Leonie, he knew she was St Vires daughter and he at first wanted to use her to hit out at the nobleman. But now he also wants to hurt St Vire because of how badly he treated Leonie. Leonie disappears from Avon court, and Rupert, who was due to meet her, follows her trail to France. He rescues her from St Vire but when Justin catches up with them he won't tell them why the Comte De St Vire who kidnapped her, has an interest in her. He takes her and Rupert to Paris, where Leonie makes her social debut, and becomes the toast of Paris society. But Avon's former mistress, Henriette, tells her that all of society is laughing at her, because they know that she is St Vire's bastard daughter. So the Duke of Avon is in love with the daughter of his enemy.
