Music sung by Frenchmen bored Mathilde to death, yet Julien, who always made a point of being present when the audience came out of the Opera, noticed that she made a point of getting taken there as often as she could. He thought he noticed that she had lost a little of that brilliant neatness of touch which used to be manifest in everything she did. She would sometimes answer her friends with jests rendered positively outrageous through the sheer force of their stinging energy. He thought that she made a special butt of the marquis de Croisenois. That young man must be desperately in love with money not to give the go-by to that girl, however rich she maybe, thought Julien. And as for himself, indignant at these outrages on masculine self-respect, he redoubled his frigidity towards her. Sometimes he went so far as to answer her with scant courtesy. In spite of his resolution not to become the dupe of Mathilde's signs of interest, these manifestations were so palpable on certain days, and Julien, whose eyes were beginning to be opened, began to find her so pretty, that he was sometimes embarrassed. "These young people of society will score in the long run by their skill and their coolness over my inexperience," he said to himself. "I must leave and put an end to all this." The marquis had just entrusted him with the administration of a number of small estates and houses which he possessed in Lower Languedoc. A journey was necessary; M. de la Mole reluctantly consented. Julien had become his other self, except in those matters which concerned his political career. "So, when we come to balance the account," Julien said to himself, as he prepared his departure, "they have not caught me. Whether the jests that mademoiselle de la Mole made to those gentlemen are real, or whether they were only intended to inspire me with confidence, they have simply amused me. "If there is no conspiracy against the carpenter's son, mademoiselle de la Mole is an enigma, but at any rate, she is quite as much an enigma for the marquis de Croisenois as she is to me. Yesterday, for instance, her bad temper was very real, and I had the pleasure of seeing her snub, thanks to her favour for me, a young man who is as noble and as rich as I am a poor scoundrel of a plebeian. That is my finest triumph; it will divert me in my post-chaise as I traverse the Languedoc plains." He had kept his departure a secret, but Mathilde knew, even better than he did himself, that he was going to leave Paris the following day for a long time. She developed a maddening headache, which was rendered worse by the stuffy salon. She walked a great deal in the garden, and persecuted Norbert, the marquis de Croisenois, Caylus, de Luz, and some other young men who had dined at the Hôtel de la Mole, to such an extent by her mordant witticisms, that she drove them to take their leave. She kept looking at Julien in a strange way.
