The executioner placed the ladder against the scaffold. 'She looked at me,' says Pirot, 'with a gentle countenance and an expression full of gratitude and tenderness, and with tears in her eyes. "Sir," she said to me in a pretty loud tone, which showed how self-possessed she was, but as courteous as it was firm, "we are not yet to separate. You promised not to leave me till my head is off; I hope that you will keep your word." And as I answered nothing, because the tears and sighs which I could only with difficulty restrain robbed me of all power of speech, she added, "I beseech you, sir, to forgive me and not to regret the time you have given to me. I am sorry, for my part, to have given you so little satisfaction, at least at certain moments; I beg your pardon for it. But I cannot die without asking you to say a _De profundis_ on the scaffold at the moment of my death, and a mass to-morrow. Remember me, sir, and pray for me."' Pirot remarks, 'If I had not been at that moment more deeply moved than I had ever been in my life, I should have had many things to reply to her courtesies, and I should have promised her more than one mass; but I found it impossible to say anything more than "Yes, madam, I will do all that you bid me."' Just as she was walking up the steps Madame de Brinvilliers found herself next to Desgrez. She then asked his forgiveness for the trouble she had given him, and begged him to say a few masses and to pray for her. She ended her 'compliment' by saying that 'she was his servant, and so she would die on the scaffold.' Then she added, 'Adieu, sir.' The throng was immense. Madame de Sévigné, who had come to witness the execution from the window of one of the houses on the bridge Notre Dame, writes: 'Never was such a crowd seen, nor Paris so moved or so eager.' The marchioness knelt down on the scaffold, her face turned towards the river. 'It was at that moment,' says Pirot, 'that I saw her so intent upon herself, so wholly occupied with what I had said we would do on the scaffold, telling me with such wonderful composure all that was necessary, and making me pass from one thing to another in due order without any prompting from me, wholly absorbed in what I said to her to prepare her for death, without the appearance of any wandering in her thoughts.
