"Aha!" I laughed incredulously, and then, swiftly driven forward by an overpowering impulse, I dropped on my knees and seized her hands with a convulsive grasp. "Rosa! Rosa!"--my voice nearly broke--"you must know that I love you. Say that you love me--that you would love me whether Clarenceux were dead or alive." An infinite tenderness shone in her face. She put out her hand, and to calm me stroked my hair. "Carl!" she whispered. It was enough. I got up. I did not kiss her. A servant entered, and said that some one from the theatre had called to see mademoiselle on urgent business. Excusing herself, Rosa went out. I held open the door for her, and closed it slowly with a sigh of incredible relief. Then I turned back into the room. I was content to be alone for a little while. Great God! The chair which Rosa had but that instant left was not empty. Occupying it was a figure--the figure of the man whose portrait hung on the wall--the figure of the man who had haunted me ever since I met Rosa--the figure of Lord Clarenceux, whom Rosa had seen dead. At last, oh, powers of hell, I knew you! The inmost mystery stood clear. In one blinding flash of comprehension I felt the fullness of my calamity. This man that I had seen was not a man, but a malign and jealous spirit--using his spectral influences to crush the mortals bold enough to love the woman whom he had loved on earth. The death of Alresca, the unaccountable appearances in the cathedral, in the train, on the steamer--everything was explained. And before that coldly sneering, triumphant face, which bore the look of life, and which I yet knew to be impalpable, I shook with the terrified ague of a culprit. A minute or a thousand years might have passed. Then Rosa returned. In an instant the apparition had vanished. But by her pallid, drawn face and her gray lips I knew that she had seen it. Truly she was cursed, and I with her! CHAPTER XVII THE MENACE From the moment of my avowal to Rosa it seemed that the evil spirit of the dead Lord Clarenceux had assumed an ineffable dominion over me. I cannot properly describe it; I cannot describe it all. I may only say that I felt I had suddenly become the subject of a tyrant who would punish me if I persisted in any course of conduct to which he objected. I knew what fear was--the most terrible of all fears--the fear of that which we cannot understand. The inmost and central throne of my soul was commanded by this implacable ghost, this ghost which did not speak, but which conveyed its ideas by means of a single glance, a single sneer.
