After the box was opened, the witness added, he had told the marquise, that the commissary Picard said to Lachaussee that there were strange things in it; but the lady blushed, and changed the subject.He asked her if she were not an accomplice.She said, "What! I?" but then muttered to herself: " Lachaussee ought to be sent off to Picardy." The witness repeated that she had been after Sainte-Croix along time about the box, and if she had got it she would have had his throat cut.The witness further said that when he told Briancourt that Lachaussee was taken and would doubtless confess all, Briancourt, speaking of the marquise, remarked, "She is a lost woman." That d'Aubray's daughter had called Briancourt a rogue, but Briancourt had replied that she little knew what obligations she was under to him; that they had wanted to poison both her and the lieutenant's widow, and he alone had hindered it.He had heard from Briancourt that the marquise had often said that there are means to get rid of people one dislikes, and they can easily be put an end to in a bowl of soup.
The girl Edme Huet, a woman of Brescia, deposed that Sainte-Croix went to see the marquise every day, and that in a box belonging to that lady she had seen two little packets containing sublimate in powder and in paste: she recognised these, because she was an apothecary's daughter.She added that one day Madame de Brinvilliers, after a dinner party, in a merry mood, said, showing her a little box, "Here is vengeance on one's enemies: this box is small, but holds plenty of successsions!" That she gave back the box into her hands, but soon changing from her sprightly mood, she cried, "Good heavens, what have I said? Tell nobody." That Lambert, clerk at the palace, told her he had brought the packets to Madame from Sainte-Croix; that Lachaussee often went to see her; and that she herself, not being paid ten pistoles which the marquise owed her, went to complain to Sainte-Croix, threatening to tell the lieutenant what she had seen; and accordingly the ten pistoles were paid;further, that the marquise and Sainte-Croix always kept poison about them, to make use of, in case of being arrested.
Laurent Perrette, living with Glazer, said that he had often seen a lady call on his mistress with Sainte-Croix; that the footman told him she was the Marquise de Brinvilliers; that he would wager his head on it that they came to Glazer's to make poison; that when they came they used to leave their carriage at the Foire Saint-Germain.
Marie de Villeray, maid to the marquise, deposed that after the death of M.d'Aubray the councillor, Lachaussee came to see the lady and spoke with her in private; that Briancourt said she had caused the death of a worthy men; that Briancourt every day took some electuary for fear of being poisoned, and it was no doubt due to this precaution that he was still alive; but he feared he would be stabbed, because she had told him the secret about the poisoning;that d'Aubray's daughter had to be warned; and that there was a similar design against the tutor of M.de Brinvillier's children.
Marie de Villeray added that two days after the death of the councillor, when Lachaussee was in Madame's bedroom, Couste, the late lieutenant's secretary, was announced, and Lachaussee had to be hidden in the alcove by the bed.Lachaussee brought the marquise a letter from Sainte-Croix.
Francois Desgrais, officer, deposed that when he was given the king's orders he arrested the marquise at Liege; that he found under her bed a box which he sealed; that the lady had demanded a paper which was in it, containing her confession, but he refused it; that on the road to Paris the marquise had told him that she believed it was Glazer who made the poisons for Sainte-Croix; that Sainte-Croix, who had made a rendezvous with her one day at the cross Saint-Honore, there showed her four little bottles, saying, "See what Glazer has sent me." She asked him for one, but Sainte-Croix said he would rather die than give it up.He added that the archer Antoine Barbier had given him three letters written by the marquise to Theria; that in the first she had told him to come at once and snatch her from the hands of the soldiers; that in the second she said that the escort was only composed of eight persons, who could he worsted by five men;that in the third she said that if he could not save her from the men who were taking her away, he should at least approach the commissary, and killing his valet's horse and two other horses in his carriage, then take the box, and burn it; otherwise she was lost.
Laviolette, an archer, deposed that on the evening of the arrest.
the marquise had a long pin and tried to put it in her mouth; that he stopped her, and told her that she was very wicked; that he perceived that people said the truth and that she had poisoned all her family;to which she replied, that if she had, it was only through following bad advice, and that one could not always be good.
Antoine Barbier, an archer, said that the marquise at table took up a glass as though to drink, and tried to swallow a piece of it; that he prevented this, and she promised to make his fortune if only he would save her; that she wrote several letters to Theria; that during the whole journey she tried all she could to swallow pins, bits of glass, and earth; that she had proposed that he should cut Desgrais' throat, and kill the commissary's valet; that she had bidden him get the box and burn it, and bring a lighted torch to burn everything; that she had written to Penautier from the Conciergerie; that she gave him, the letter, and he pretended to deliver it.
