It was Sainte-Croix' widow who on August 8--that is, the day when the box was discovered--sent word to Madame de Brinvilliers at Picpus that things belonging to her were under seal. The marchioness instantly sent some one to find the box. As that was no longer in Sainte-Croix' house, a servant was sent off to Commissary Picard to tell him that Madame de Brinvilliers desired to speak to him without delay. Picard answered that he was busy. The marchioness, however, herself hurried to Madame de Sainte-Croix, insisting on the box being given to her. It was nine o'clock at night. 'She complained of its having been sealed up, offered money to obtain it, proposed to break the seals in order to take out what was inside, and to substitute something else.' But the box had been taken away. 'It's very amusing,' she said, 'for Commissary Picard to carry off a box that belongs to me!' She got some one to take her to Sergeant Cluet, whom she made come down, so that she might speak to him from her carriage. 'The lady told him that Pennautier had come to her, and told her that he was anxious about the box, and would give fifty golden louis to have what was in it. She also said that all that was in the said box concerned Pennautier and herself, and that they had done everything in concert.' We see here the first step in a manoeuvre which Madame de Brinvilliers afterwards developed. Knowing that several of the papers in the box concerned Pennautier, she sought to link her cause with the financier's, speculating on his high position and influence. Cluet answered that he could do nothing without the commissary. Accordingly the marchioness hurried off to him at eleven o'clock at night. Picard sent down word that he could not receive her till the morning. In the morning, August 9, the commissary received a visitor from a Châtelet[3] attorney named Delamarre, to whom the marchioness had intrusted her interests. He told the commissary that the little box was of great importance to Madame de Brinvilliers, begging him to send it back to her, and saying 'that she would give him all she had in the world.' 'There came also a man in black' (it was Briancourt) 'who told him that the marchioness would give him anything he could wish for.'
