"I have come to you, señor, on the part of my friend Count Silvio de Mora, who conceives himself to be seriously aggrieved by you."

"Indeed, sir! in what way? I have never exchanged a word with him that I am aware of, though I certainly observed that he was looking unpleasantly at me last night."

"The count's grievance is a very clear and distinct one, señor. He was, as you are doubtless aware, betrothed to Donna Mercedes de Balen. That young lady, as a consequence, he tells me, of her being captured by the Carlists, wrote by the hand of her brother to say that the shock had been so great that she was determined never to marry, but to spend her life in good works. The count, my friend, assented, though deeply troubled by the decision. The count now finds that by common report Donna Mercedes--"

"Stay, sir," Arthur said sternly, "don't let the name of Donna Mercedes de Balen be brought into this matter. The Count Silvio de Mora conceives that he has a quarrel with me and demands satisfaction. That is quite enough as between two gentlemen. I shall be perfectly prepared to give him that satisfaction. A friend of mine will wait upon you to arrange the preliminaries."

"Nothing can be more satisfactory," the Spaniard said. He and Arthur exchanged deep bows, and he went out.

Arthur sat down to think deeply. He was now twenty, with an experience that made him feel years older. Donna Mercedes was a year younger, and gradually for a long time past he had been aware of the fact that it was more than the friendship brought about by their close intimacy that he felt towards her. She was in all respects a charming girl. She was bright, pleasant, and natural, one of the acknowledged beauties of Madrid. He had often told himself that it would be wrong of him to presume, on the friendship of Count Leon, to raise his eyes to his sister, who was co-heiress with her sisters to large estates which had been the property of her mother. The queen's remark about her blushes when she mentioned him had often recurred to him, and had suggested to him that possibly it was not mere gratitude she felt for him. The queen's gift had placed him in a better position than before, so that it would not be necessary to ask her to wait five years before he would be able to support her in the style of life to which she had been accustomed. He had been intimate with the family in a manner altogether contrary to Spanish customs, and it might well be that she had come to care for him.

"Well, I will speak to her brother about it after this affair is over," he concluded; "and now I will send word to Don Lopez Parona. I have seen a good deal of him, and no doubt he will act for me."

He sent Roper off with a note, and an hour later the young man came in.

"Don Lopez," he said, "Count Silvio de Mora has forced a quarrel upon me, and it is necessary that I should fight him. I have sent for you to ask if you will be my second in the affair.

"With pleasure, Captain Hallett. What arrangements do you wish made?"
