"Prince Ivan," I said, "you are excited and overwrought. Zara meant no slight to you in leaving the room before your song was finished. I am quite sure of that. She is kindness itself--her nature is all sweetness and gentleness. She would not willingly offend you--" "Offend me!" he exclaimed; "she could not offend me if she tried. She could tread upon me, stab me, slay me, but never offend me. I see you are sorry for me--and I thank you. I kiss your hand for your gentle pity, mademoiselle." And he did so, with a knightly grace that became him well. I thought his momentary anger was passing, but I was mistaken. Suddenly he raised his arm with a fierce gesture, and exclaimed: "By heaven! I will wait no longer. I am a fool to hesitate. I may wait a century before I draw out of Casimir the secret that would enable me to measure swords with my rival. Listen!" and he grasped my shoulder roughly. "Stay here, you! If Casimir returns, tell him I have gone for a walk of half an hour. Play to him--keep him occupied--be my friend in this one thing--I trust you. Let him not seek for Zara, or for me. I shall not be long absent." "Stay!" I whispered hurriedly, "What are you going to do? Surely you know the power of Heliobas. He is supreme here. He could find out anything he chose. He could---" Prince Ivan looked at me fixedly. "Will you swear to me that you actually do not know?" "Know what?" I asked, perplexed. He laughed bitterly, sarcastically. "Did you ever hear that line of poetry which speaks of 'A woman wailing for her demon-lover'? That is what Zara does. Of one thing I am certain--she does not wail or wait long; he comes quickly." "What do you mean?" I exclaimed, utterly mystified. "Who comes quickly? I am sure you do not know what you are talking about." "I DO know," he replied firmly; "and I am going to prove my knowledge. Remember what I have asked you." And without another word or look, he threw open the velvet curtains of the portiere, and disappeared behind them. Left to myself, I felt very nervous and excited. All sorts of odd fancies came into my head, and would not go away, but danced about like Will-o'-the-wisps on a morass. What did Prince Ivan mean? Was he mad? or had he drunk too much wine? What strange illusion had he in his mind about Zara and a demon? Suddenly a thought flashed upon me that made me tremble from head to foot. I remembered what Heliobas had said about twin flames and dual affinities; and I also reflected that he had declared Zara to be dominated by a more powerful force than his own. But then, I had accepted it as a matter of course that, whatever the force was, it must be for good, not evil, over a being so pure, so lovely and so intelligent as Zara.
