In the evening a friend, one Bertin, came to dine with Derues. Bertin was a short, hustling, credulous, breathless gentleman, always in a hurry, with a great belief in the abilities of M. Derues. He found the little man in excellent spirits. Bertin asked if he could see Mme. de Lamotte. Mme. Derues said that that was impossible, but that her husband had given her some medicine which was working splendidly. The young de Lamotte called to see his mother. Derues took him into her room; in the dim light the boy saw her sleeping, and crept out quietly for fear of disturbing her. The Derues and their friends sat down to dinner. Derues kept jumping up and running into the sick room, from which a horrible smell began to pervade the house. But Derues was radiant at the success of his medicine. "Was there ever such a nurse as I am?" he exclaimed. Bertin remarked that he thought it was a woman's and not a man's place to nurse a lady under such distressing circumstances. Derues protested that it was an occupation he had always liked. Next day, February 1, the servant was still at Montrouge; Mme. Derues was again sent out shopping; again Derues was alone with his patient. But she was a patient no longer; she had become a corpse. The highly successful medicine administered to the poor lady by her jolly and assiduous nurse had indeed worked wonders. Derues had bought a large leather trunk. It is possible that to Derues belongs the distinction of being the first murderer to put that harmless and necessary article of travel to a criminal use. He was engaged in his preparations for coffining Mme. de Lamotte, when a female creditor knocked insistently at the door. She would take no denial. Clad in his bonnet and gown, Derues was compelled to admit her. She saw the large trunk, and suspected a bolt on the part of her creditor. Derues reassured her; a lady, he said, who had been stopping with them was returning to the country. The creditor departed. Later in the day Derues came out of the house and summoned some porters. With their help the heavy trunk was taken to the house of a sculptor, a friend of Derues, who agreed to keep it in his studio until Derues could take it down to his place in the country. Bertin came in to dinner again that evening, and also the young de Lamotte. Derues was gayer than ever, laughing and joking with his guests. He told the boy that his mother had quite recovered and gone to Versailles to see about finding him some post at the Court. "We'll go and see her there in a day or two," he said, "I'll let you know when."
