“And so,” he at last made up his mind to ask, carried away by professional curiosity, “and so it was a laboratory explosion which put you in this nice condition? What devilish powder were you concocting then?”

Guillaume, ever since he had seen Bertheroy thus studying his injury, had, in spite of his sufferings, given marked signs of annoyance and agitation. And as if the real secret which he wished to keep lay precisely in the question now put to him, in that powder, the first experiment with which had thus injured him, he replied with an air of restrained ardour, and a straight frank glance: “Pray do not question me, master. I cannot answer you. You have, I know, sufficient nobility of nature to nurse me and care for me without exacting a confession.”

“Oh! certainly, my friend,” exclaimed Bertheroy; “keep your secret. Your discovery belongs to you if you have made one; and I know that you are capable of putting it to the most generous use. Besides, you must be aware that I have too great a passion for truth to judge the actions of others, whatever their nature, without knowing every circumstance and motive.”

So saying, he waved his hand as if to indicate how broadly tolerant and free from error and superstition was that lofty sovereign mind of his, which in spite of all the orders that bedizened him, in spite of all the academical titles that he bore as an official savant, made him a man of the boldest and most independent views, one whose only passion was truth, as he himself said.

He lacked the necessary appliances to do more than dress the wound, after making sure that no fragment of any projectile had remained in the flesh. Then he at last went off, promising to return at an early hour on the morrow; and, as the priest escorted him to the street door, he spoke some comforting words: if the bone had not been deeply injured all would be well.

On returning to the bedside, Pierre found his brother still sitting up and seeking fresh energy in his desire to write home and tranquillise his loved ones. So the priest, after providing pen and paper, again had to take up the lamp and light him. Guillaume fortunately retained full use of his right hand, and was thus able to pen a few lines to say that he would not be home that night. He addressed the note to Madame Leroi, the mother of his deceased mistress, who, since the latter’s death, had remained with him and had reared his three sons. Pierre was aware also that the household at Montmartre included a young woman of five or six and twenty, the daughter of an old friend, to whom Guillaume had given shelter on her father’s death, and whom he was soon to marry, in spite of the great difference in their ages. For the priest, however, all these were vague, disturbing things, condemnable features of disorderly life, and he had invariably pretended to be ignorant of them.

“So you wish this note to be taken to Montmartre at once?” he said to his brother.

“Yes, at once. It is scarcely more than seven o’clock now, and it will be there by eight. And you will choose a reliable man, won’t you?”

“The best course will be for Sophie to take a cab. We need have no fear with her. She won’t chatter. Wait a moment, and I will settle everything.”

Sophie, on being summoned, at once understood what was wanted of her, and promised to say, in reply to any questions, that M. Guillaume had come to spend the night at his brother’s, for reasons which she did not know. And without indulging in any reflections herself, she left the house, saying simply: “Monsieur l’Abbe’s dinner is ready; he will only have to take the broth and the stew off the stove.”
