La Reynie adds: 'La Trianon agrees that she told the girl Voisin that the journey to Saint-Germain was the cause of her mother's arrest, that this journey would do her harm, that she would be involved in some affair of state. At the same time, La Voisin did not appear to be pleased with Blessis (and consequently had no reason to make any efforts to secure his liberty). What is still more considerable, La Trianon and the girl Monvoisin agree that the state crime mentioned in the horoscope was the journey to Saint-Germain.' 'Finally,' observes La Reynie, 'this petition has been mentioned at the trial, long before the girl Monvoisin was arrested.' On September 27, 1679, Louvois wrote to Louis XIV: 'Your Majesty will find in this packet what Lesage has said about the journey of La Voisin to Saint-Germain; he cites so many people as witnesses to his allegations that it is difficult to believe he invented them.' And La Reynie gives confirmation: 'Before making her declaration, the girl Monvoisin said something about it to two prisoners who are with her. Finally, she tried to do away with herself by strangling before making these same declarations.' The assassination of the Duchess de Fontanges was intended to crown the vengeance of Madame de Montespan. La Voisin exclaimed, in regard to this, when dining with La Trianon: 'Oh! what a fine thing is a lover's spite!' Romani and Bertrand were engaged to poison the young lady at the same time that La Voisin was killing Louis _XIV_; but the poisons employed against her were to be less rapid, so that 'she might die a lingering death,' said the accomplices, 'and that it might be said that she had died of grief at the death of the king.' Romani had planned to disguise himself as a cloth merchant. Bertrand was to follow him as a valet. They were to present their wares to the duchess, and even if she did not take any cloth, 'she would not refrain from taking gloves,' said Romani, 'because those he would bring from Grenoble would be very well made, and ladies never failed to take some of them when they were well made, and the gloves would have the same effect as the piece of cloth.' They actually sent to Rome and Grenoble for gloves of the finest quality, and Romani 'prepared' them according to the recipes of the magicians. We find among La Reynie's papers a series of little notes which clearly prove the plot against the life of Madame de Fontanges. A last feature in the case is not the least surprising.
