Rouletabille was given a seat between the delegato and the examining magistrate who had arrived while Mme. Edith had been testifying, and he gave his evidence (or rather, reasoned the matter out) holding the “oldest knife known to the human race” in his hand. It seemed definitely established that the guilty person could have been no other than one of the living men and women who were near the dead man and whom I have enumerated above, when Rouletabille proved with a logical accuracy that overwhelmed the examining magistrate and plunged the delegato into despair that the deed could only have been committed by the dead man himself. The four persons at the postern gate and the two persons in Old Bob’s room had each been looking at the others and had not lost sight of each other while someone was killing Bernier a few steps away, so it was impossible to believe that the killing could have been done by any other than the victim.
To this the examining magistrate, greatly interested, replied by inquiring whether any of us had reason to suspect any motive for suicide on the part of Bernier, to which Rouletabille answered that the supposition of suicide might easily be laid aside and that of accident substituted for it. “The weapon of the crime,” as he called ironically the “oldest knife known to the human race,” testified to the truth of this theory by its presence. Rouletabille declared that there would be no chance of an assassin meditating the commission of a murder with an old piece of stone as an instrument. And still less could one believe that Bernier, if he had resolved upon suicide, would not have found another means toward his end than the one which had been used. But if, on the contrary, that stone, which might have attracted his attention by its strange form, had been picked up by Pere Bernier, and if he had happened to slip and fall while holding it in his hand, everything would be explained and very simply. Pere Bernier, undoubtedly, must have thus unfortunately fallen upon this triangular flint which had pierced his heart.
After Rouletabille had stated this hypothesis, the physician was recalled, the wound examined once more and confronted with the fatal object from which the scientific conclusion was reached that the wound was made by the object. From this to the theory of accident, as stated by Rouletabille, there was only a step. The judges spent six hours in clearing up the matter—six hours during which they questioned us without weariness but without result.
As to Mme. Edith and your humble servant, after some futile and useless questions, asked while the doctors were at the bedside of Old Bob, we were allowed to leave the room and we went to sit in the little parlor just outside the bedroom and were there when the magistrates were ready to depart. The door of this parlor which opened upon the corridor of the Square Tower had not been closed. We could hear the sobs and groans of Mere Bernier, who was watching beside the body of her husband which had been carried into the lodge. Between this body and the wounded man, the injury to one as inexplicable as the death of the other, the situation of both Mrs. Rance and myself had become extremely painful, in spite of Rouletabille’s efforts, and all the terrors which we had experienced before grew pale and simple before the thought of what might be yet to come. Edith suddenly seized me by the hand and cried out:
“Do not leave me! I beg of you, don’t leave me! I have only you left. I do not know where Prince Galitch is—I do not know anything about my husband. That is what makes this so horrible. Arthur sent me a message, saying that he was going in search of Tullio. He does not know even yet that Bernier has been murdered. Has he found the ‘hangman of the sea’? It is from this man—from Tullio now that I expect the truth! And not a word has come! It is horrible!”
As she took my hand so confidingly and held it for a moment in her own, I felt that I was for Mme. Edith with all my heart and soul and I assured her that she might rely upon my devotion. We murmured a few words of trust and eternal fidelity to each other in low voices while there in the corridor we could see, passing back and forth, the dark forms of the emissaries of justice, now preceded, now followed by Rouletabille and M. Darzac. Rouletabille never failed to cast a glance in our direction every time he had the opportunity. The window remained open.
“Ah, he is watching us!” exclaimed Mme. Edith. “Why is that, I wonder? Probably we are in his way and M. Darzac’s when we remain here. But, whatever may happen, we shall not stir, shall we, M. Sainclair?”
“You ought to be grateful to Rouletabille,” I ventured to remind her; “for his intervention and his silence relative to the ‘oldest knife known to the human race.’ If the officers had learned that this stone dagger belonged to your uncle, Bob, what could have hindered them from placing him under arrest? Or if they knew that Bernier in dying had accused Larsan of his murder, the story of the accident would have found very little credence.”
I placed an emphasis upon these last words.
“Oh!” she cried, bitterly. “Your friend has as many good reasons to keep silence as I have! And I dread only one thing, M. Sainclair—I dread only one thing!”
