His days and nights were made up of hours of suffering, for he was living in the fixed idea, and still more in the sentiment than in the idea, that she was his and yet not his, that she was conquered and still at liberty, captured and yet impregnable. He was living at her side, as near her as could be, without ever reaching her, and he loved her with all the unsatiated longings of his body and his soul. He began to write to her again, as he had done at the commencement of their _liaison_. Once before with ink he had vanquished her early scruples; once again with ink he might be victorious over this later and obstinate resistance. Putting longer intervals between his visits to her, he told her in almost daily letters of the fruitlessness of his love. Now and then, when he had been very eloquent and impassioned and had evinced great sorrow, she answered him. Her letters, dated for effect midnight, or one, two, or three o'clock in the morning, were clear and precise, well considered, encouraging, and afflicting. She reasoned well, and they were not destitute of wit and even fancy, but it was in vain that he read them and re-read them, it was in vain that he admitted that they were to the point, well turned, intelligent, graceful, and satisfactory to his masculine vanity; they had in them nothing of her heart, they satisfied him no more than did the kisses that she gave him in the house at Auteuil. He asked himself why this was so, and when he had learned them by heart he came to know them so well that he discovered the reason, for a person's writings always afford the surest clue to his nature. Spoken words dazzle and deceive, for lips are pleasing and eyes seductive, but black characters set down upon white paper expose the soul in all its nakedness.
