As to the Lady in Black, it could easily be seen that she was making a powerful effort to hide the sentiments of horror which, in spite of all, pierced through her troubled glance, and to hide from us the emotion which made her cling feverishly to the arm of her young companion. Robert Darzac, too, had the sombre and resolute mien of a judge. But that which most of all added to our surprise and affright was the entrance of Pere Jacques, Walter and Mattoni into the Square Tower. All three were armed with muskets, and placed themselves in silence before the door, where they stood with military precision while they received from the lips of Rouletabille the order to let no person _go out_ from the Old château. Edith was overwhelmed with terror, and demanded of Mattoni and Walter, both of whom were greatly attached to her, what their presence signified and what their weapons threatened; but, to my great astonishment, they returned no answer. Then the little woman rushed to the door which gave access to Old Bob’s room, and, extending her two arms across the threshold, as if to bar the passage, she cried: “What are you going to do? You do not mean to kill _him_?” “No, Madame,” replied Rouletabille, gravely. “We are going to judge _him_. And in order to be sure that the judges shall not be executioners we are all going to swear upon the body of Pere Bernier, after having laid down our arms, that each of us will keep guard over himself.” And he led us into the chamber where Mere Bernier continued to groan beside the bier of her spouse whom “the oldest knife known to the human race” had smitten. There we laid aside our revolvers and took the oath which Rouletabille exacted. Mrs. Rance alone made some difficulties about giving up the weapon which Rouletabille was well aware that she had concealed in her clothing. But upon the urging of the reporter who made her understand that the general disarming ought to reassure her, she finally consented. The oath having been taken, Rouletabille, with the Lady in Black still on his arm, went from the funereal chamber into the corridor; but instead of directing our steps toward the apartment of Old Bob as we expected him to do, he went straight to the door which afforded entrance to the chamber of “the body too many.” And, drawing from his pocket the little special key of which I have spoken, he opened the door. We were all astonished in entering the rooms which had been occupied by M. and Mme. Darzac to see upon M. Darzac’s desk the drawing board, the wash drawing upon which our friend had worked at the side of Old Bob in the latter’s workshop in the Court of the Bold, and also the little dish full of red paint and the tiny brush drenched with the paint. And, lastly, in the middle of the desk, there was placed, appearing very much at its ease, upon its bloody jaws, “the oldest skull of humanity.”
