Perceiving the perplexity of the magistrates, Father Philibin, hitherto silent and attentive, indulged in a light laugh. 'This shows,' he said, 'how difficult it is to arrive at the truth.... By the way, Monsieur le Procureur de la République, matters are much the same with the stain which you are now examining. One of us fancied it to be some initialling, a kind of flourish. But, for my part, I believe it to be a blot which some pupil tried to efface with his finger.' 'Is it usual for the masters to initial the copy-slips?' asked Daix. 'Yes,' Brother Fulgence acknowledged, 'that is done at our school.' 'Ah! no,' cried Simon and Marc in unison, 'we never do it in the Communal schools.' 'You are mistaken,' said Mademoiselle Rouzaire, although I do not stamp my copies, I have sometimes initialled them.' With a wave of the hand La Bissonnière stopped the discussion, for he knew by experience what a muddle is reached when one enters into secondary questions of personal habits. The copy-slip, the missing corner of it, the possible existence of a stamp and a paraph would all have to be studied in the course of the investigation. For the moment he now contented himself with asking the witnesses to relate how the crime had been discovered. Mignot had to say that the open window had attracted his attention and that he had raised an outcry on perceiving the victim's body. Mademoiselle Rouzaire explained how she had hastened to the spot and how, on the previous evening, she had brought Zéphirin home from the Capuchin Chapel, when he had sprung into the room by the window. Father Philibin and Brother Fulgence in their turn related how chance had connected them with the tragedy, in what condition they had found the room, and in what particular spot they had discovered the paper gag, which they had merely unfolded before placing it on the table. Finally, Marc indicated a few observations which he had made on his arrival, subsequent to that of the others. La Bissonnière thereupon turned to Simon and began to question him: 'You have told us that you came home at twenty minutes to twelve, and that the whole house then seemed to you to be perfectly quiet. Your wife was asleep----' At this point Daix interrupted his superior: 'Monsieur le Procureur,' said he, 'is it not advisable that Madame Simon should be present? Could she not come down here a moment?' La Bissonnière nodded assent, and Simon went to fetch his wife, who soon made her appearance.
