"Do so and I will believe it. If it is true," she muttered, clenching her fist--"if it is true, I shall bitterly punish him for the deception." "Come with me to-morrow evening at eight o'clock to Briarfield's rooms in Jermyn Street, and I'll engage you shall see them together." "If I thought so--but no," she said, breaking off impetuously. "I cannot come; how can I--how can I?" "Ask Mrs. Bellin to come with you," I suggested. "I cannot do that." "Why not?" She looked at me strangely for a moment, then walked to the other end of the room. When she returned, her face was flushed with anger. "Why do you come here with these infamous tales, sir?" she cried excitedly. "I do not believe you!" "Put me to the proof. Come tomorrow evening and you shall see for yourself." "You are the enemy of the man I love." "I am the bitter enemy of the man who pretends to love you, because I believe he killed his brother." "Mr. Denham, I could tell--but no, no! I must be silent." "What do you mean?" I asked eagerly, thinking she was about to reveal her suspicions. Olivia thought for a few moments, then put her hand suddenly into mine. "I will be with you at a quarter to eight to-morrow, and if it is true what you say--oh, if it is true----" "Here is my card," said I, forcing it into her hand. "Wear a veil and come to my rooms in Duke Street. I will wait you at the door, and we will go to the chambers of this villain." "He is no villain." "I say he is, Miss Bellin, and I'll prove him to be so to-morrow." "Do it," she said, fixing me with a glance, "and you shall see how bitterly I shall punish his treachery. Now go, Mr. Denham, and meet me to-morrow evening as you have arranged." I bowed and left the room in silence. As I passed through the door I looked back, and saw she had thrown herself on the couch, crying bitterly. The sight perplexed me. "Does she know anything," I thought, "or does she believe Felix is really Francis? Well, when she and Rose Gernon come face to face, the truth will be revealed." The truth was stranger than even I suspected. CHAPTER XI. TRANSFORMATION. My interview with Olivia passed off better than I had expected. If she had ordered me out of the house, I would only have looked on it as the just punishment for what must have appeared my impertinent interference in what did not concern me. The very fact that she listened so quietly proved that she suspected Felix was masquerading as her lover. She could only be assured of this by overhearing his interview with Rose Gernon, and therefore accepted my invitation to go to the Jermyn Street rooms. If their tenant was Francis, he would resent the intrusion of Rose, but if Felix, the two confederates would doubtless talk of their guilty secret.
