“One thing more I mean to do,” said Carrington: “and here everything will depend on your courage and nerve. You may depend upon it that Mr. Ratcliffe will offer himself before you go north. He does not suspect you of making trouble, and he will not think about you in any way if you let him alone and keep quiet. When he does offer himself you will know it; at least your sister will tell you if she has accepted him. If she refuses him point blank, you will have nothing to do but to keep her steady. If you see her hesitating, you must break in at any cost, and use all your influence to stop her. Be bold, then, and do your best. If everything fails and she still clings to him, I must play my last card, or rather you must play it for me. I shall leave with you a sealed letter which you are to give her if everything else fails. Do it before she sees Ratcliffe a second time. See that she reads it and, if necessary, make her read it, no matter when or where. No one else must know that it exists, and you must take as much care of it as though it were a diamond. You are not to know what is in it; it must be a complete secret. Do you understand?” Sybil thought she did, but her heart sank. “When shall you give me this letter?” she asked. “The evening before I start, when I come to bid good-bye; probably next Sunday. This letter is our last hope. If, after reading that, she does not give him up, you will have to pack your trunk, my dear Sybil, and find a new home, for you can never live with them.” He had never before called her by her first name, and it pleased her to hear it now, though she generally had a strong objection to such familiarities. “Oh, I wish you were not going!” she exclaimed tearfully. “What shall I do when you are gone?” At this pitiful appeal, Carrington felt a sudden pang. He found that he was not so old as he had thought. Certainly he had grown to like her frank honesty and sound common sense, and he had at length discovered that she was handsome, with a very pretty figure. Was it not something like a flirtation he had been carrying on with this young person for the last month? A glimmering of suspicion crossed his mind, though he got rid of it as quickly as possible. For a man of his age and sobriety to be in love with two sisters at once was impossible; still more impossible that Sybil should care for him.
