"Your duty! Of course, it is always duty; jealousy is quite unknown to a man in holy orders. But there is a difference. You can't tell me the least what I'm thinking of; you always suppose the worst of every one. Your duty! And what, pray, is your duty?" "To warn Miss Ware and her governess," he answered promptly. "Warn her of what?" said the stranger, sternly. "Warn her that a villain has got into this house." The interesting guest sprang to his feet, with his fists clenched. But he did not strike. He hesitated, and then he said: "Look here; I'll not treat you as I would a man. You wish me to strike you, you Jesuit, and to get myself into hot water. But I shan't make a fool of myself. I tell you what I'll do with you--if you dare to injure me in the opinion of any living creature, by one word of spoken or hinted slander, I'll make it a police-office affair; and I'll bring out the whole story you found it on; and we'll see which suffers most, you or I, when the world hears it. And now, Mr. Carmel, you're warned. And you know I'm a fellow that means what he says." Mr. Carmel turned with a pale face, and left the room. I wonder what the stranger thought. I have often pondered over that scene; and, I believe, he really thought that Mr. Carmel would not, on reflection, venture to carry out his threat. CHAPTER XV. A WARNING. We had heard nothing of Mr. Carmel's arrival. He had not passed our windows, but drove up instead by the back avenue; and now he was gone, and there remained no record of his visit but the letter which Laura held in her fingers, while we both examined it on all sides, and turned it over. It was directed, "To Miss Ware and Miss Grey. Malory." And when we opened it we read these words: "Dear Young Ladies,--I know a great deal of the gentleman who has been permitted to take up his residence in the house adjoining Malory. It is enough for me to assure you that no acquaintance could be much more objectionable and unsafe, especially for young ladies living alone as you do. You cannot, therefore, exercise too much caution in repelling any advances he may make.-- Your true friend, "E. Carmel." The shock of reading these few words prevented my speaking for some seconds. I had perfect confidence in Mr. Carmel's warning. I was very much frightened. And the vagueness of his language made it the more alarming. The same thoughts struck us both. What fools we were! How is he to be got out of the house? Whom have we to advise with? What is to be done? In our first panic we fancied that we had got a burglar or an assassin under our roof. Mr. Carmel's letter, however, on consideration, did not bear out quite so violent a conclusion. We resolved, of course, to act upon that letter; and I blamed myself too late for having permitted the stranger to make, even in so slight a way, my acquaintance.
