“I saw that Natacha negotiated with them. But what had she to place in the scales against the life of her father? Nothing—except the fortune that she would have one day.

“Some words she spoke about the impossibility of immediate marriage, about poverty which could always knock at the door of any mansion, remarks that I was able to overhear between Natacha and Boris Mourazoff, which to him meant nothing, put me definitely on the right road. And I was not long in ascertaining that the negotiations in this formidable affair were taking place in the very house of Trebassof! Pursued without by the incessant spying of Koupriane, who sought to surprise her in company with the Nihilists, watched closely, too, by the jealous supervision of Boris, who was jealous of Michael Nikolaievitch, she had to seize the only opportunities possible for such negotiations, at night, in her own home, the sole place where, by the very audacity of it, she was able to play her part in any security.

“Michael Nikolaievitch knew Annouchka. There was certainly the point of departure for the negotiations which that felon-officer, traitor to all sides, worked at will toward the realization of his own infamous project. I do not think that Michael ever confided to Natacha that he was, from the very first, the instrument of the revolutionaries. Natacha, who sought to get in touch with the revolutionary party, had to entrust him with a correspondence for Annouchka, following which he assumed direction of the affair, deceiving the Nihilists, who, in their absolute penury, following the revolt, had been seduced by the proposition of General Trebassof’s daughter, and deceiving Natacha, whom he pretended to love and by whom he believed himself loved. At this point in the affair Natacha came to understand that it was necessary to propitiate Michael Nikolaievitch, her indispensable intermediary, and she managed to do it so well that Boris Mourazoff felt the blackest jealousy. On his side, Michael came to believe that Natacha would have no other husband than himself, but he did not propose to marry a penniless girl! And, fatally, it followed that Natacha, in that infernal intrigue, negotiated for the life of her father through the agency of a man who, underhandedly, sought to strike at the general himself, because the immediate death of her father before the negotiation was completed would enrich Natacha, who had given Michael so much to hope. That frightful tragedy, Sire, in which we have lived our most painful hours, appeared to me, confident of Natacha’s innocence, as absolutely simple as for the others it seemed complicated. Natacha believed she had in Michael Nikolaievitch a man who worked for her, but he worked only for himself. The day that I was convinced of it, Sire, by my examination of the approach to the balcony, I had a mind to warn Natacha, to go to her and say, ‘Get rid of that man. He will betray you. If you need an agent, I am at your service.’ But that day, at Krestowsky, destiny prevented my rejoining Natacha; and I must attribute it to destiny, which would not permit the loss of that man. Michael Nikolaievitch, who was a traitor, was too much in the ‘combination,’ and if he had been rejected he would have ruined everything. I caused him to disappear! The great misfortune then was that Natacha, holding me responsible for the death of a man she believed innocent, never wished to see me again, and, when she did see me, refused to have any conversation with me because I proposed that I take Michael’s place for her with the revolutionaries. She would have nothing to do with me in order to protect her secret. Meantime, the Nihilists believed they were betrayed by Natacha when they learned of the death of Michael, and they undertook to avenge him. They seized Natacha, and bore her off by force. The unhappy girl learned then, that same evening, of the attack which destroyed the datcha and, happily, still spared her father. This time she reached a definite understanding with the revolutionary party. Her bargain was made. I offer you for proof of it only her attitude when she was arrested, and, even in that moment, her sublime silence.”

While Rouletabille urged his view, the Emperor let him talk on and on, and now his eyes were dim.

“Is it possible that Natacha has not been the accomplice, in all, of Michael Nikolaievitch?” he demanded. “It was she who opened her father’s house to him that night. If she was not his accomplice she would have mistrusted him, she would have watched him.”

“Sire, Michael Nikolaievitch was a very clever man. He knew so well how to play upon Natacha, and Annouchka, in whom she placed all her hope. It was from Annouchka that she wished to hold the life of her father. It was the word, the signature of Annouchka that she demanded before giving her own. The evening Michael Nikolaievitch died, he was charged to bring her that signature. I know it, myself, because, pretending drunkenness, I was able to overhear enough of a conversation between Annouchka and a man whose name I must conceal. Yes, that last evening, Michael Nikolaievitch, when he entered the datcha, had the signature in his pocket, but also he carried the weapon or the poison with which he already had attempted and was resolved to reach the father of her whom he believed was assuredly to be his wife.”

“You speak now of a paper, very precious, that I regret not to possess, monsieur,” said the Tsar coldly, “because that paper alone would have proved to me the innocence of your protegee.”

“If you have not it, Sire, you know well that it is because I have wished you to have it. The corpse had been searched by Katharina, the little Bohemian, and I, Sire, prevented Koupriane from finding that signature in Katharina’s possession. In saving the secret I have saved General Trebassof’s life, who would have preferred to die rather than accept such an arrangement.”

The Tsar stopped Rouletabille in his enthusiastic outburst.

“All that would be very beautiful and perhaps admirable,” said he, more and more coldly, because he had entirely recovered himself, “if Natacha had not, herself, with her own hand, poisoned her father and her step-mother!—always with arsenate of soda.”
