Pierre was on the point of protesting, but he realised that it would be useless to discuss the subject at such a moment, and so he merely waved his hand to signify that he should act in spite of the prohibition were it necessary. In point of fact, his anxiety had increased, and, when the cab at last drew up before the house, it was with real relief that he saw his brother alight without evincing any marked feebleness. He himself quickly paid the driver, well-pleased, too, at finding that nobody, not even a neighbour, was about. And having opened the door with his latch key, he helped the injured man to ascend the steps.
A little night lamp glimmered faintly in the vestibule. On hearing the door open, Pierre's servant, Sophie, had at once emerged from the kitchen. A short, thin, dark woman of sixty, she had formed part of the household for more than thirty years, having served the mother before serving the son. She knew Guillaume, having seen him when he was a young man, and doubtless she now recognised him, although well-nigh ten years had gone by since he had last crossed that threshold. Instead of evincing any surprise, she seemed to consider his extraordinary return quite natural, and remained as silent and discreet as usual. She led, indeed, the life of a recluse, never speaking unless her work absolutely required it. And thus she now contented herself with saying: "Monsieur l'Abbe, Monsieur Bertheroy is in the study, and has been waiting there for a quarter of an hour."
At this Guillaume intervened, as if the news revived him: "Does Bertheroy still come here, then? I'll see him willingly. His is one of the best, the broadest, minds of these days. He has still remained my master."
A former friend of their father,—the illustrious chemist, Michel Froment,—Bertheroy had now, in his turn, become one of the loftiest glories of France, one to whom chemistry owed much of the extraordinary progress that has made it the mother-science, by which the very face of the earth is being changed. A member of the Institute, laden with offices and honours, he had retained much affection for Pierre, and occasionally visited him in this wise before dinner, by way of relaxation, he would say.
"You showed him into the study? All right, then, we will go there," said the Abbe to the servant. "Light a lamp and take it into my room, and get my bed ready so that my brother may go to bed at once."
While Sophie, without a word or sign of surprise, was obeying these instructions, the brothers went into their father's former laboratory, of which the priest had now made a spacious study. And it was with a cry of joyous astonishment that the savant greeted them on seeing them enter the room side by side, the one supporting the other. "What, together!" he exclaimed. "Ah! my dear children, you could not have caused me greater pleasure! I who have so often deplored your painful misunderstanding."
Bertheroy was a tall and lean septuagenarian, with angular features. His yellow skin clung like parchment to the projecting bones of his cheeks and jaw. Moreover, there was nothing imposing about him; he looked like some old shop-keeping herbalist. At the same time he had a fine, broad, smooth brow, and his eyes still glittered brightly beneath his tangled hair.
"What, have you injured yourself, Guillaume?" he continued, as soon as he saw the bandaged hand.
Pierre remained silent, so as to let his brother tell the story as he chose. Guillaume had realised that he must confess the truth, but in simple fashion, without detailing the circumstances. "Yes, in an explosion," he answered, "and I really think that I have my wrist broken."
At this, Bertheroy, whose glance was fixed upon him, noticed that his moustaches were burnt, and that there was an expression of bewildered stupor, such as follows a catastrophe, in his eyes. Forthwith the savant became grave and circumspect; and, without seeking to compel confidence by any questions, he simply said: "Indeed! an explosion! Will you let me see the injury? You know that before letting chemistry ensnare me I studied medicine, and am still somewhat of a surgeon."
