The Fat and the Thin by Émile Zola

Florent had just begun to study law in Paris when his mother died. She lived at Le Vigan, in the department of the Gard, and had taken for her second husband one Quenu, a native of Yvetot in Normandy, whom some sub-prefect had transplanted to the south and then forgotten there. He had remained in employment at the sub-prefecture, finding the country charming, the wine good, and the women very amiable. Three years after his marriage he had been carried off by a bad attack of indigestion, leaving as sole legacy to his wife a sturdy boy who resembled him. It was only with very great difficulty that the widow could pay the college fees of Florent, her elder son, the issue of her first marriage. He was a very gentle youth, devoted to his studies, and constantly won the chief prizes at school. It was upon him that his mother lavished all her affection and based all her hopes.

Perhaps, in bestowing so much love on this slim pale youth, she was giving evidence of her preference for her first husband, a tender-hearted, caressing Provencal, who had loved her devotedly. Quenu, whose good humour and amiability had at first attracted her, had perhaps displayed too much self-satisfaction, and shown too plainly that he looked upon himself as the main source of happiness. At all events she formed the opinion that her younger son-and in southern families younger sons are still often sacrificed-would never do any good; so she contented herself with sending him to a school kept by a neighbouring old maid, where the lad learned nothing but how to idle his time away. The two brothers grew up far apart from each other, as though they were strangers.
