About this time the King, wearied of the perpetual coldness of Madame de Verneuil, which not even his excessive clemency had sufficed to overcome, made a last attempt to compel her gratitude by forwarding letters under the great seal, authorizing the Comte d'Entragues to retire to his estate of Marcoussis, and re-establishing both himself and his son-in-law in all their wealth and honours, save the posts which they had held under the crown, and their respective governments. D'Auvergne, however, was still a prisoner in the Bastille, where, after lashing himself into fury for a few months, he adopted the more prudent and manly alternative of study, and thus contrived to educe enjoyment even from his privations. Yet still the haughty spirit of the Marquise scorned to yield. She was indeed living in her own house, the gift of the monarch against whom she exhibited this firm and calm defiance, and surrounded by luxuries, the whole of which she owed to his uncalculating generosity; but she could not, and would not, forget that she was, nevertheless, an exile from the Court, and a prisoner within the boundary of her estate, while the Queen, whom she had affected to despise, was triumphing in her disgrace. Nor was it until the month of September, when Henry, who was pining for her return, finally declared that no proof of culpability having been brought against her, she must be forthwith duly and fully acquitted of the crime with which she had been charged, that the icy barrier was at last broken down, and the haughty Marquise condescended to acknowledge herself indebted to her sovereign. The King did not satisfy himself with this mere declaration, though he had caused it to be legally registered by the Parliament; but, fearful lest some further revelations might be made, by which she might become once more involved, he moreover strictly forbade his Attorney-general to take any new steps whatever relating to the conspiracy, or tending further to incriminate any of its presumed members.[301] The jealousy which existed between the two houses of Bourbon and Lorraine, and which Henry was anxious if possible to terminate, coupled perhaps with no small feeling of wounded vanity, determined him to bestow the hand of Louise Marguerite de Lorraine, Demoiselle de Guise (who, since she had been in the household of the Queen, had lent a less willing ear than formerly to his renewed gallantries), upon François, Prince de Conti; and accordingly the marriage was celebrated with great pomp in the month of July, in the presence of their Majesties and the whole Court. Madame de Conti herself asserts that the Queen first suggested this union, and did everything in her power to effect it;[302] for which it is highly probable that Marie had a double motive, as the antecedents of Mademoiselle de Guise might well excuse her jealousy.
