“You remember, my friend,” the reporter replied, “that little piece of paper which you brought back to the Château of Hercules on the day when, without giving me any warning, you took it upon yourself to follow the trail of the excellent Brignolles, who had come to make a short stay in the Midi? That bit of paper, which bore the heading of the Sorbonne and the two syllables, _bonnet_, gave me the most important assistance. First of all, the circumstances under which you found it--you recollect that you picked it up after you had seen Larsan and Brignolles?--rendered it precious to me. And then the place where it had been thrown was nearly a revelation for me when I began to take up the search for the real Darzac, after I had gained the conviction that his was ‘the body too many’ which had been tied up in the sack and carried out in it.” And Rouletabille went on in the simplest manner possible, taking me in his narrative over the different phases necessary for my comprehension of the mysteries which, up to that time, had remained so inexplicable to every one of us. The first step in his reasoning had come from the conclusions which he had drawn from the fact that the paint on the drawing would dry less than fifteen minutes after it had been laid on, and following that, the other formidable fact that a lie must have been told by one of the two manifestations of Darzac. Bernier, under the cross examination to which Rouletabille subjected him before the return of the man who had carried the sack, had reported the lying words of the man whom everyone had believed to be Darzac. That was what had astonished Bernier--that the man who had come in at six o’clock had not told him that the man who had entered at six o’clock _was not he_! He was trying to conceal the fact that there existed a second manifestation of Darzac and he would have had no interest in concealing it, if his own personality had been the true one. That was clear as the light of day! When the horror of the thing dawned upon Rouletabille, he nearly swooned. His limbs refused to support him; his teeth chattered; everything grew black in front of his eyes. But he was not entirely without hope, even yet. Bernier might have been mistaken. Perhaps he had not correctly understood the words which M. Darzac had spoken in his amazement and confusion! Rouletabille decided that he himself would question M. Darzac. Then he would soon see. How he longed for his return! It would be for M. Darzac himself to “close the circle.” He waited impatiently--and when Darzac returned how the young reporter’s feeble hopes were crushed! “Did you look at the man’s face?” he had asked; and when the so-called Darzac replied, “No--I did not look at him!” Rouletabille could hardly hide his joy. It would have been so easy for Larsan to have answered, “I saw him. The face was that of Larsan!” And the young man had not understood that this was the last piece of malice--the furthest limit of hatred in the mind
