"And," he went on, turning at the other end of their promenade, "perhaps you will not believe me, but only a few weeks ago there was such a power in the hands of a Frenchman—of an Alsatian, perhaps I should say, but a man who had preserved his loyalty to France—a scientist of European reputation—a man who had discovered that this earth had a spirit, a living soul, and who could gain control of it—so complete a control, that he could draw it out and leave the earth dead—a man who—But there, I am wearying you; I am sure you must think that I am telling you some fairy tale."

"By no means, my dear prince," said Lord Orrel, doing his best to keep his voice steady, and not quite succeeding. "In the first place, I am quite sure that you would not speak so seriously on a subject that was not serious; and, in the second place, I can assure you that I am most deeply interested."

"A thousand pardons, my lord," said the prince. "Of course you would not think that of me. We have both of us lived too long to indulge in romance, and yet, if I could tell you the whole story, you would say that you have never heard such a romance as this."

"And, if it is not trespassing too far upon your confidence, my dear prince, I should be only too happy to hear you tell the whole story," said his lordship, with an unmistakable note of curiosity in his tone.

"I can tell you part of the story," replied the prince; "but not here. It is so strange, and it might have meant so much, not only to France, but to the world, that I can only tell it to you where no other ears than ours can hear it, and even then only under your solemn pledge of secrecy."

"As for the first condition, my dear prince," replied Lord Orrel, "I will ask you to take a glass of wine with me in my sitting-room. As for the second, you have my word."

"And, therefore, both conditions are amply satisfied. Let us go, and I will tell you the strangest story you have ever heard."

CHAPTER VIII

By the time the prince had ceased speaking there was not the slightest doubt in Lord Orrel's mind that, in some most mysterious manner, he was connected with the discovery which Hardress had made when he took the mutilated body out of the waters of the Channel. Perhaps even the unknown dead might have been someone near and dear to him. It seemed to him utterly impossible either to doubt the prince's word or to believe that two such discoveries could have been made by two men at the same time, or even that there could exist at the same time on earth two men whose genius, once put into practice, could make them rival masters of the world.

And supposing that he knew part of the story which the prince was going to tell him—the sequel, and, from a practical point of view, the all-important portion—ought he to tell him what he knew too? He was under no actual pledge of secrecy to his associates in the great Trust, but still he felt that he was under an honourable obligation to keep the story of the discovery to himself. On the other hand, granted that the prince knew the first half, would it be right—would it be honourable, according to his own exact code of honour, to keep the sequel from him? Perhaps the prince even had a definite personal interest in the scheme; and, in that case, to keep silence would be to rob him of his prior rights. What was he to do?
