I ascended the stairs wondering what would be the outcome of my interview. I wanted to ascertain who the woman was and the nature of the relations between her and Sybil. When I entered the room a rather elderly lady with whitish hair severely brushed back and attired in deep black rose to meet me, bowing stiffly and saying-- "I have not the honour of your acquaintance, Mr Morton, and am rather curious to know what you want with me." "Well, madam," I replied, "the fact is I want to ask you a question. The Honourable Sybil Burnet has been travelling with you dressed as a lady's-maid, and I am here to learn where she has now gone." The woman started in surprise, and glared at me. She probably, from my disguise as a working-man, put me down as a detective. "And my reply to you, sir, is that Miss Sybil's destination is her own affair. We parted, and she has gone south. That is all I know." "But you also know the reason why she is masquerading as a maid; why at Fort William and at Oban you made people believe she was your maid. You had a motive, and I think you may as well admit it." "I do not see your right to question me about my private affairs!" she exclaimed angrily. "This is monstrous!" "I have no desire to pry into your affairs, madam," I answered, quite coolly. "The Honourable Sybil is a friend of mine, and I am anxious to know her whereabouts," I said. "But I cannot tell you what I don't know myself. She went on to Carlisle--that's all I know." "She parted from you suddenly. Why?" I asked. "Shall I tell you? Because she is in fear of being followed," I exclaimed, and, smiling, added, "I think, madam, that I hold greater knowledge of the family than perhaps even you do yourself. I have known the Scarcliffs all my life. Old Lady Scarcliff is greatly upset regarding Sybil's protracted absence. They are beginning to think that something has happened to her. I can now tell her that she has been with you, masquerading as your maid, and that you refuse all information concerning her. You know, I daresay, that the police are actively trying to find her on the application of her brother, Lord Scarcliff?" My threat caused her some consternation. I could see that from the way she fumed and fidgeted. "To tell Lady Scarcliff such a thing would only be to throw a blame upon myself of which I am entirely innocent," she protested. "I assure you that if I knew where she had gone, I would tell you." "No, pardon me, madam. You would not. You believe that I'm a detective." "Your actions certainly betray you," she exclaimed resentfully. "You've been watching us closely--for what reason?" "Well," I replied slowly. "The fact is, I am fully aware of the secret love existing between Sybil Burnet and Arthur Rumbold." "Sybil and Arthur?" she cried, turning pale and looking me straight in the face. "What do you mean? Arthur--my boy, Arthur!" I nodded in the affirmative.
