But Xavier de Condé, Prince of Bourbon, would never drink another cup of chocolate. As soon as his door closed behind him, a sternly-repressed flood of passion broke out, and he spent half the remainder of the night walking, in his stockinged feet, up and down his big bedchamber, with clenched teeth and tight-gripped hands, his brain seething with a thousand thoughts of passion, and his white, twitching lips shaping unspoken words of rage, bitterness, and despair. It was a cruel irony that Fate had wrought on him and his ancient house. The possible sceptre of the world had been offered to his hereditary enemies, the Republicans of France, and, if Fargeau had held to his compact, the compact for which he had given his daughter to his son, he would have been master of France; and Fargeau would have kept it, for he was a loyal Frenchman; and his son would have married a future Queen of France! And now not only had France refused the sceptre and snatched the crown from him, but the sceptre had passed by some bitter caprice of Fate into the hands of France's hereditary enemies. What could he say or do? Nothing. It was maddening--worse than maddening. He had pledged his honour, and could tell no one--but even if he could, what then? The secret was out--worse--it was in the hands of men who could make the ideal a reality. They could not even give him back the power if they would, for the knowledge was theirs already, and they could act on it while he could not. The more he thought the faster the fever that was burning in his blood increased. His lips and tongue grew parched. His steps grew irregular and faltering. The veins in his head were beating on his brain like sledge-hammers. The lights began to waver before his eyes. He felt instinctively that madness--that long-inherited curse of his race--was coming. What if he should really go mad and babble not only of this great secret, but also of all the plots and intrigues of which he had been the centre! How many devoted friends and adherents would be consigned to prison and exile--perhaps even to the scaffold! The very thought chilled him back into sanity for the time being. He rapped sharply at the wall, and presently Felix appeared, half-dressed, and doing his best to stifle a yawn. "Felix," said the prince, who was now sitting in his arm-chair with his head between his hands, "bid Marie arouse mam'selle immediately, and request her to dress and come to me. I am unwell--another of my attacks, I fear--and she only knows what to do for me. Quick--I need her at once." Felix vanished, and within ten minutes the marquise was in her father's room; but by this time the blood was beating on his brain again, and the fierce light of insanity was beginning to dawn in his eyes. With the valet's help she partly undressed him and got him to bed. Then she locked the door and braced herself for what she instinctively knew must be a terrible ordeal.
