The case of the Duc de Praslin--tried, like that of Louis Napoleon, at the Luxemburg--was very painful and very dramatic. The duke was a member of the Choiseul family, whose name he bore in addition to his own. Under Louis Philippe he was attached to the household of the Duchess of Orleans, and in 1845, having previously been a deputy, was raised to the peerage. In 1824 he had married the daughter of Marshal Sebastiani, and that marriage, for seventeen years, seemed a happy one. Many children were born of the union; and it was not until 1841 that any sign of disagreement manifested itself between the husband and the wife. The jealousy of the latter was then roused; not, it was afterwards said, for the first time. A young lady named Henriette Deluzy-Desportes had just been engaged as governess. She was lively, graceful, and moderately pretty, and soon gained such an ascendency over her pupils as well as over the duke as to cause the duchess the greatest uneasiness. To make matters worse, the duchess was advised by her husband not to trouble herself any more about the education of her children, which was now, he said, in excellent hands. At last, after suffering the deepest vexation (of which she gave a touching account in her private diary, found after her death), she resolved to apply for a separation. Then, to avoid all scandal, the old marshal made representations to his son-in-law, while two other persons addressed remonstrances to Mlle. Deluzy. An arrangement was entered into by which the duchess agreed to abandon the lawsuit while Mlle. Deluzy was to leave the house. The marshal agreed to pay her an annuity of 1,500 francs, which was guaranteed by the duchess. The arrangement was made in the month of June, 1847; and on the 18th of July following Mlle. Deluzy left the Hôtel Sebastiani in the Rue du Faubourg Saint-Honoré, where the Praslin family had taken up their residence. The duchess had gained the victory. But she was by no means satisfied with the position of things, and felt that she was still menaced by an approaching danger. Her husband, it appeared, had uttered some dark threats. “He will never forgive me,” she wrote in her diary. “The future terrifies me. I cannot think of it without trembling.” The day the governess left the Paris house the whole Praslin family started for the duke’s country place at Vaux-Praslin. They were not to return to Paris until the 17th of August. Meanwhile the duke made three journeys to Paris, remaining there each time for two or three days; and he never failed to pay a visit to Mlle. Deluzy, who had gone to live with a schoolmistress in the Rue Harlay. The valet who accompanied the duke on all these journeys remarked on one occasion that the governess saw the duke back to the railway station, and on wishing him good-bye burst into tears.
