History of english literature

Canto XII
Leila safeguarded. In effort to pursue his life and interests, in England, Don Juan first safeguards his adopted daughter, Leila, by seeking, finding, and employing a suitable guardian for her, in the person of Lady Pinchbeck, a woman whom London society consider a person of good character, possessed of admirable wit, but rumoured to be unchaste.
Canto XIII
In society. At the house of Lady Adeline Amundeville and her husband, Lord Henry Amundeville, the narrator informs that Don Juan's hostess, Lady Adeline, is "the fair most fatal Juan ever met", the "queen bee, the glass of all that's fair, / Whose charms made all men speak and women dumb". Anglo–Russian diplomatic relations require meetings between Lord Henry and Don Juan ("the envoy of a secret Russian mission") whom the lord befriends into a regular guest at their mansion in London. Lady and Lord Amundeville invite distinguished guests to a party at their estate in the country. The narrator then describes the country environs of the Amundeville estate and the décor of the estate house, which then are followed with mock-catalogues of the social activities and of the personalities of the upper-class ladies and gentlemen who are the high society of royal Britain. The narrator Byron views the country party of the Amundevilles as English ennui. Canto XIII concludes with the guests and their hosts retiring for the evening.
Canto XIV
Country life. During a fox hunt, Don Juan acquits himself in riding to the hounds, proving to be a handsome, dashing, and witty man who is very attractive to the lady guests at the Amundeville country house, including the flirtatious Duchess of Fitz-Fulke, who has set her eye upon him. Jealous of the experienced duchess, who has had many love affairs, the hostess, Lady Adeline, resolves to protect the "inexperienced" Don Juan from the sexual enticements and depredations of the Duchess of Fitz-Fulke. Although Lady Adeline and Don Juan both are twenty-one years old, and, despite having a vacant heart and a cold, but proper marriage to Lord Henry, she is not in love with Don Juan. Later, the narrator Byron tells the reader whether or not Lady Adeline and Don Juan entered into a love affair; about which canto XIV contains the line: “ ’Tis strange — but true; for truth is always strange; Stranger than fiction”.
