It was an indescribable scene—a moment never to be forgotten! At the gesture of Rouletabille, the door of the panel swung open, pushed by an invisible hand, just as it had been on that terrible night which had witnessed the mystery of “the body too many.”

And the form of a man appeared. Clamors of surprise, of joy and of terror filled the Square Tower. The Lady in Black uttered a heart rending cry: “Robert! Robert! Robert!”

And it was a cry of joy! Two Darzacs before us so exactly similar that every one of us save the Lady in Black might have been deceived. But her heart told her the truth, even admitting that her reason, notwithstanding the triumphant conclusion of Rouletabille, might have hesitated. Her arms outstretched, her eyes alight with love and joy, she rushed toward the second manifestation of Darzac—the one which had descended from the panel. Mathilde’s face was radiant with new life; her sorrowful eyes which I had so often beheld fixed with sombre gloom upon that other, were shining upon this one with a joy as glorious as it was tranquil and assured. It was he! It was he whom she had believed lost—whom she had sought in vain in the visage of the other and had not found there and, therefore, had accused herself, during the weary hours of day and night, of folly which was akin to madness.

As to the man who, up to the last moment I had not believed to be guilty—as to that wretch who, unveiled and tracked to earth, found himself suddenly face to face with the living proof of his crimes, he attempted yet again, one of the daring coups which had so often saved him. Surrounded on every side, he yet endeavored to flee. Then we understood the audacious drama which in the last few moments, he had played for our benefit. When he could no longer have any doubt as to the issue of the discussion which he was holding with Rouletabille, he had had the incredible self control to permit nothing of his emotions to appear, and had also been able to prolong the situation, permitting Rouletabille to pursue at leisure the thread of the argument at the end of which he knew that he would find his doom, but during the progress of which he might discover perchance some means of escape. And he had effected his manœuvres so well that at the moment when we beheld the other Darzac advancing toward us, we could not hinder the imposter from disappearing at one bound within the room which had served as the bedchamber of Mme. Darzac and closing the door violently behind him with a rapidity which was nothing less than marvellous. We only knew that he had vanished when it was too late to stop his flight.

Rouletabille, during the scene which had passed had thought only of guarding the door opening into the corridor and he had not noticed that every movement of the false Darzac, as soon as he realized that he was being convicted of his imposture, had been in the direction of Mme. Darzac’s room. The reporter had attached no importance to these movements, knowing as he did that this room did not offer any way by which Larsan might escape. But, however, when the scoundrel was behind the door which afforded his last refuge, our confusion increased beyond all proportions. One might have thought that we had become suddenly bereft of our senses. We knocked on the door. We cried out. We thought of all his strokes of genius—of his marvellous escapes in the past!

“He will escape us! He will get away from us again!”

Arthur Rance was the most enraged of us all. Mme. Edith, who was clinging to my arm, drove her finger nails into my hand in a paroxysm of nervous fear. None of us paid any heed to the Lady in Black and Robert Darzac who, in the midst of this tempest, seemed to have forgotten everything, even the clamor and confusion around them. Neither one had spoken a word but they were looking into each other’s eyes as though they had discovered another world—the world which is love. But they had not discovered it; they had merely found it again, thanks to Rouletabille.

The latter had opened the door of the corridor and summoned the three domestics to our assistance. They entered with their rifles. But it was axes that were needed. The door was solid and barricaded with heavy bolts. Pere Jacques went out and fetched a beam which served us as a battering ram. Each of us exerted all his strength and, finally, we saw the door beginning to give way. Our anxiety was at its height. In vain, we told ourselves that we were about to enter a room in which there were only walls and barred windows. We expected anything—or, rather, we expected nothing, for in the mind of each and every one of us was the recollection of the disappearances, the flights, the actual “dissolution of matter” which Larsan had brought about in times past and which at this moment haunted us and drove us nearly mad.

When the door had commenced to yield, Rouletabille directed the servants to take up their guns, with the order, however, that the weapons were to be used only in case it should be impossible to capture Larsan living. Then the young reporter set his shoulder to the door with one last powerful effort and as the boards, wrenched from their hinges, fell to the ground, he was the first to enter the room.

We followed him. And behind him, upon the threshold, we all halted, stupefied by the sight which met our eyes. Larsan was there—plainly to be seen by everyone. And this time there was no difficulty in recognizing him. He had removed his false beard; he had put aside his “Darzac mask”; he had resumed once more the pale, clean-shaven face of that Frederic Larsan whom we had known at the Château of Glandier. And his presence seemed to fill the entire room. He was lying back comfortably in an easy chair in the center of the room and was looking at us with his great, calm eyes. His arm was stretched along the arm of the chair. His head was resting on the cushion at the back. One would have said that he was giving us an audience and was waiting for us to make known our business. It seemed to me that I could even discern an ironical smile on his lips.
