The Painted Veil by William Somerset Maugham

Her happiness, sometimes almost more than she could bear, renewed her beauty. Just before she married, beginning to lose her first freshness, she had looked tired and drawn. The uncharitable said that she was going off. But there is all the difference between a girl of twenty-five and a married woman of that age. She was like a rosebud that is beginning to turn yellow at the edges of the petals, and then suddenly she was a rose in full bloom. Her starry eyes gained a more significant expression; her skin (that feature which had always been her greatest pride and most anxious care) was dazzling: it could not be compared to the peach or to the flower; it was they that demanded comparison with it. She looked eighteen once more. She was at the height of her glowing loveliness. It was impossible not to remark it and her women friends asked her in little friendly asides if she was going to have a baby. The indifferent who had said she was just a very pretty woman with a long nose admitted that they had misjudged her. She was what Charlie had called her the first time he saw her, a raging beauty.

They managed their intrigue with skill. He had a broad back, he told her (‘I will not have you swank about your figure,' she interrupted lightly), and it did not matter about him; but for her sake they mustn't take the smallest risk. They could not meet often alone, not half often enough for him, but he had to think of her first, sometimes in the curio shop, now and then after luncheon in her house when no one was about; but she saw him a good deal here and there. It amused her then to see the formal way he spoke to her, jovial, for he was always that, with the same manner he used with every one. Who could imagine when they heard him chaff her with that charming humour of his that so lately he had held her in his passionate arms?
