But all at once the thunderbolt fell. It was not without some hesitation that Blaise had agreed to make the little pavilion his home, for he knew that there was an idea of reducing him to the status of a mere piece of machinery. But at the birth of his little girl he bravely decided to accept the proposal, and to engage in the battle of life even as his father had engaged in it, mindful of the fact that he also might in time have a large family. But it so happened that one morning, when he went up to the house to ask Maurice for some instructions, he heard from Constance herself that the young man had spent a very bad night, and that she had therefore prevailed on him to remain in bed. She did not evince any great anxiety on the subject; the indisposition could only be due to a little fatigue. Indeed, for a week past the two cousins had been tiring themselves out over the delivery of a very important order, which had set the entire works in motion. Besides, on the previous day Maurice, bareheaded and in perspiration, had imprudently lingered in a draught in one of the sheds while a machine was being tested. That evening he was seized with intense fever, and Boutan was hastily summoned. On the morrow, alarmed, though he scarcely dared to say it, by the lightning-like progress of the illness, the doctor insisted on a consultation, and two of his colleagues being summoned, they soon agreed together. The malady was an extremely infectious form of galloping consumption, the more violent since it had found in the patient a field where there was little to resist its onslaught. Beauchêne was away from home, travelling as usual. Constance, for her part, in spite of the grave mien of the doctors, who could not bring themselves to tell her the brutal truth, remained, in spite of growing anxiety, full of a stubborn hope that her son, the hero, the demi-god necessary for her own life, could not be seriously ill and likely to die. But only three days elapsed, and during the very night that Beauchêne returned home, summoned by a telegram, the young fellow expired in her arms. In reality his death was simply the final decomposition of impoverished, tainted, _bourgeois_ blood, the sudden disappearance of a poor, mediocre being who, despite a façade of seeming health, had been ailing since childhood. But what an overwhelming blow it was both for the mother and for the father, all whose dreams and calculations it swept away! The only son, the one and only heir, the prince of industry, whom they had desired with such obstinate, scheming egotism, had passed away like a shadow; their arms clasped but a void, and the frightful reality arose before them; a moment had sufficed, and they were childless.
