Pirot tried to show her that, assuming she was guilty, her duty was to disclose all her accomplices, to reveal the composition of her poisons and the means of counteracting them. She interrupted him: 'Sir, are there not some sins that are unpardonable in this world, either from their gravity or their number? Are there not some so atrocious or so numerous that the Church cannot remit them?' 'Believe, madam, that there are no sins irremissible in this life,' answered the priest, and he enlarged on this theme with force and warmth and an infectious faith. Conviction by degrees took possession of the prisoner's soul, and with it there dawned a gleam of regeneration, hope in a future life serene and happy--glorious, as the abbé said--and with the thought her heart was changed. '"Sir," she answered me, "I am convinced of all you tell me. I believe that God can pardon all sins; I believe that He has often exercised this power; but all my trouble now is to know whether He will apply His power to one so wretched as I." I told her that she must hope that God would take pity on her in His infinite mercy. She began to describe in general terms the whole of her life, and from that moment I saw that her heart was touched, and she burst into tears beholding her wretchedness.' By the contagion of his sympathetic kindness, and by the light of redemption, Pirot had in a few hours melted this heart of brass like wax. 'After she had given me an outline of her life, knowing that I had not yet said mass, she intimated spontaneously that it was time to say it, and that I might go down to the chapel for that purpose. She begged me say it to our Lady on her behalf, so as to obtain the pardon of which she stood in need, and asked me to come up again as soon as the sacrifice had been completed, saying that she would be present in spirit, since she was not permitted to attend in person, and that she thought of telling me in detail on my return that which she had so far told me only in general terms. 'After my mass,' continues Pirot, 'as I was taking a sip of wine in the jailer's room before returning to the tower, I learned from Monsieur de Sency, librarian to the Palais, that Madame de Brinvilliers was condemned. I went upstairs and found the marchioness awaiting me in great serenity. '"It is only by dying by the hand of the executioner," she said, "that I can win salvation. If I had died at Liége before my arrest, where should I be now? And if I had not been taken, what would my end have been? I will confess my crime to the judges to whom I have denied it hitherto. I fancied I could conceal it, flattering myself that without my confession there would have been nothing to convict me, and that I was not bound to accuse myself. To-morrow, at my last examination, I mean to repair the ill that I have done at the others.
