Olivier thought she was out. She usually had a lesson at that hour: but at the last moment she had received word from her pupil, telling her that she could not have her that day. She was secretly pleased, although it meant a few francs less in that week's earnings: but she was very tired and she lay down on her bed: she was very glad to be able to rest for once without reproaching herself. Olivier came in from school bringing another boy with him. They sat down in the next room and began to talk. She could hear everything they said: they thought they were alone and did not restrain themselves. Antoinette smiled as she heard her brother's merry voice. But soon she ceased to smile, and her blood ran cold. They were talking of dirty things with an abominable crudity of expression: they seemed to revel in it. She heard Olivier, her boy Olivier, laughing: and from his lips, which she had thought so innocent, there came words so obscene that the horror of it chilled her. Keen anguish stabbed her to the heart. It went on and on: they could not stop talking, and she could not help listening. At last they went out, and Antoinette was left alone. Then she wept: something had died in her: the ideal image that she had fashioned of her brother--of her boy--was plastered with mud: it was a mortal agony to her. She did not say anything to him when they met again in the evening. He saw that she had been weeping and he could not think why. He could not understand why she had changed her manner towards him. It was some time before she was able to recover herself. But the worst blow of all for her was one evening when he did not come home. She did not go to bed, but sat up waiting for him. It was not only her moral purity that was hurt: her suffering went down to the most mysterious inner depths of her heart--those same depths where there lurked the most awful feelings of the human heart, feelings over which she cast a veil, to hide them from her sight.
