On the same day that this conversation took place in the gardens of the Hôtel Wilhelmshof in Elsenau, a very different one was taking place in the prince's hotel at Vienna between Adelaide de Condé and Victor Fargeau, who, on receipt of the news of the prince's death, had obtained a few days' leave, and travelled post-haste from Petersburg to Vienna.

It was after dinner, and Madame de Condé had retired to her own room with a slight attack of nerves. The marquise and Victor Fargeau were sitting on either side of the open fireplace, with a little table, holding coffee and liqueurs, between them. Adelaide had accepted a cigarette from his case, and he had lit one too. For several minutes after her aunt had left the room she puffed daintily at her cigarette, and looked across at him with intricately-mingled feelings. At length Victor broke the silence by saying, with a note of impatience in his tone:

"And now, Mam'selle la Marquise, or, if you like it better, my most beautiful Adelaide, I have possessed my soul in patience for nearly two hours. When are you going to tell me this wonderful news of yours?"

"Wonderful, my dear Victor? Alas, it is not only that; it is most sorrowful as well." Then, bracing herself with a visible effort, she threw her half-smoked cigarette into the fireplace, and, gripping the arms of the big chair in which she was sitting, she went on, staring straight into his eyes: "It is nothing less than the story of how your father met his end, and what became of his great secret."

"Nom de Dieu!" he cried, springing to his feet; "you know that, and from whom?"

"From these English and Americans—or Anglo-Americans, as I suppose I ought to call them," she replied; "the people to whom the Fates gave the secret with your father's dead and mutilated body; the people who buried him—the man who might have been the saviour of France—in a nameless English grave."

She kept her voice as steady as she could while she was saying this; she even tried to speak coldly and pitilessly, for she had made up her mind that the reasons of state for her betrothal to this man no longer existed. She had an even higher stake to play for now, and, in spite of all her pride of blood and racial prejudice, this would not be a sacrifice; on the contrary, it would be rather a victory—and so she hardened her voice, as she had done her heart.

"Dead! mutilated!" he exclaimed again. "Yes; I knew he was dead, for he told me in his letter from Paris that he would not, and could not, survive the failure of all his hopes. There were reasons why he should not, but they are of no consequence now. He staked everything, and lost everything, and that is enough. It is not for me to be his judge, now that he has gone to the presence of the highest Judge of all."

"That was said like a good son and a true man, Victor," replied the marquise, with a swift glance of something like admiration at his flushed and handsome face. "But there is something more serious than even the death of one whom you have loved and I have most deeply respected. I heard enough from my own father, during the night he died, to convince me that these people have not only got the secret, but that they are already devoting millions to convert your father's theory into a terrible reality.

"This Viscount Branston, Lord Orrel's son, has already been across to America, and has leased the land about the Magnetic Pole from the Canadian Government. A syndicate has been formed, and even at this very moment the preliminaries of the work are being pushed forward as rapidly as possible. Within a few months they will have begun the storage station itself, and then nothing can save the world from the irresistible power which will be theirs."
