"The question was as unexpected as it was natural, and I was unprepared for it, so I made no reply, covering my silence by taking off my shoes and preparing for bed. "'Where have you been?' he asked again, this time in a tone so peremptory that I decided in an instant not to tell him. "'Out,' I answered. 'Where have you?' "At this he laughed. "'Don't be impudent,' he said. 'I do not wish to pry into your affairs. I only wanted to know where you had been because I am interested in you, and I want to help you to avoid pitfalls.' "'That's all right,' I responded graciously. 'I appreciate your kindness, but you need not be interested in where I have been to-night, because I have been engaged in a little matter that concerns you not at all.' "'Very well,' he replied, turning once more to the fire. 'I'll take your word for it; only you and I must be perfectly candid with each other, or complications may arise, that's all. By the way, I'll have to borrow you again to-morrow morning. There are a half-dozen members of Parliament coming here to discuss certain matters of state, and you would be somewhat embarrassed if you undertook to meet them.' "'That suits me,' I said, happy enough to acquiesce in anything. 'Only I'll want to get back here to-morrow evening. I have an engagement.' "The fiend eyed me narrowly for a moment, and I winced beneath his gaze. "'All right,' he said, 'you can get back, but this Parliamentary business is very important, and I _must_ have the semblance of a mortal being every morning this week.' "'That can be arranged,' I replied. Arabella could have my evenings, and he could have my mornings. That was fair enough, I thought, and so it happened. Every night for a week I spent in the company of my _fiancée_,--whose name, by the way, I never mentioned in the fiend's presence--and every morning for the same period he was in charge, conducting negotiations which only served to make me more famous. "Finally the dreadful morning came. It was Saturday, and the fiend and I were sitting together in my quarters. We had just changed places. I was in my present disembodied state, and the fiend had taken possession for the day, when there was heard in the corridor a quick nervous step which stopped as he who directed it came to my door, and a voice, which to my consternation I recognized at once as that of Arabella's father following close upon a resounding knock, cried out,-- "'This is the place. This is the kennel in which the hound lives. Open the door!' "There was not time for the fiend and me to change places. Indeed, I had hardly recognized the old gentleman's voice, when the fiend in answer to his demand opened the door.
