Marie de Medicis, who had experienced little sympathy from the great ladies of the Court, having thrown herself principally upon her Italian followers for society, had in consequence been cold and distant in her deportment to the French members of her circle; who, on their side, trammelled by the rigorous propriety of her conduct, were quite satisfied to be partially overlooked, in order that their own less scrupulous bearing might pass unnoticed by so rigid a censor; and thus, when, upon the earnest request of Madame de Villars to be introduced to the more intimate acquaintance of the Queen, the Princess succeeded in obtaining for her the privilege of the _petites entrees_ (unaware of the powerful passport to favour which she possessed), she found it difficult to account for the eagerness with which the ordinarily unapproachable Marie greeted the appearance and courted the society of the astute Duchess; nor did she for an instant dream that by facilitating the intercourse between them, she was undermining the fortunes of a brother whom she loved.
It appears extraordinary that of all the ladies about the Queen, Madame de Villars should have selected the sister of the Prince de Joinville to enable her to effect her purpose; but let her have acted from whatever motive she might, it is certain that day by day her favour became more marked; and the circumstance which most excited the surprise of Madame de Conti, was the fact that her _protegee_ was often closeted with the Queen when, for reasons sufficiently obvious, she herself and even Leonora Galigai were excluded.

In encouraging the vengeance of her new friend, Marie was well aware that she was committing an imprudence from which the more far-seeing Florentine would have dissuaded her; and thus, with that impetuosity which was destined through life to be her scourge, she resolved only to consult her own feelings.

The secret of this new discovery was consequently not divulged to her favourite; and as her cheek burned and her eye flashed, while lingering over the insults to which she had been subjected by the unscrupulous mistress of the monarch, she urged Madame de Villars to lose no time in communicating the contents of the obnoxious letters to her sovereign.
The undertaking was difficult as well as dangerous; and in the case of the Duchess it required more than usual tact and caution.

She had not only to encounter the risk of arousing the anger of Henry by accusing the woman whom he loved, but also to combat his wounded vanity when he should see his somewhat mature passion made a subject of ridicule, and, at the same time, to conceal her own motive for the treachery of which she was guilty.

This threefold trial, even daring as she was, the Duchess feared to hazard.
