One evening, therefore, shortly before Maitre Quennebert’s marriage, the fair lady set out, ostensibly on a journey which was to last a fortnight or three weeks. In reality she only made a circle in a post-chaise round Paris, which she re-entered at one of the barriers, where the duke awaited her with a sedan-chair. In this she was carried to the very house to which de Jars had brought his pretended nephew after the duel. Angelique, who had to pay dearly for her errors, remained there only twenty-four hours, and then left in her coffin, which was hidden in a cellar under the palace of the Prince de Conde, the body being covered with quicklime. Two days after this dreadful death, Commander de Jars presented himself at the fatal house, and engaged a room in which he installed the chevalier. This house, which we are about to ask the reader to enter with us, stood at the corner of the rue de la Tixeranderie and the rue Deux-Portes. There was nothing in the exterior of it to distinguish it from any other, unless perhaps two brass plates, one of which bore the words MARIE LEROUX-CONSTANTIN, WIDOW, CERTIFIED MIDWIFE, and the other CLAUDE PERREGAUD, SURGEON. These plates were affixed to the blank wall in the rue de la Tixeranderie, the windows of the rooms on that side looking into the courtyard. The house door, which opened directly on the first steps of a narrow winding stair, was on the other side, just beyond the low arcade under whose vaulted roof access was gained to that end of the rue des Deux-Portes. This house, though dirty, mean, and out of repair, received many wealthy visitors, whose brilliant equipages waited for them in the neighbouring streets. Often in the night great ladies crossed its threshold under assumed names and remained there for several days, during which La Constantin and Claude Perregaud, by an infamous use of their professional knowledge, restored their clients to an outward appearance of honour, and enabled them to maintain their reputation for virtue. The first and second floors contained a dozen rooms in which these abominable mysteries were practised. The large apartment, which served as waiting and consultation room, was oddly furnished, being crowded with objects of strange and unfamiliar form. It resembled at once the operating-room of a surgeon, the laboratory of a chemist and alchemist, and the den of a sorcerer. There, mixed up together in the greatest confusion, lay instruments of all sorts, caldrons and retorts, as well as books containing the most absurd ravings of the human mind. There were the twenty folio volumes of Albertus Magnus; the works of his disciple, Thomas de Cantopre, of Alchindus, of Averroes, of Avicenna, of Alchabitius, of David de Plaine-Campy, called L’Edelphe, surgeon to Louis XIII and author of the celebrated book The Morbific Hydra Exterminated by the Chemical Hercules.
