I arose and went to the window. I wiped my forehead, which had become moist. If this man had known Brownson, why should he not know all? Was he familiar with both engagements? It made me sick to think of it. There was no sense or reason in such emotion, for it was not likely that Sylvia's engagement had been a secret one; but I had a proud soul and could not bear to think that people about me, especially Walkirk, should be aware of Sylvia's attachment, slight as it may have been, to another than myself. I heartily wished that I had not spoken of the subject. Still, as I had spoken of it, I might as well learn all that I could. "What sort of a man was this Brownson?" I asked. "What reason was there that Miss Marcia Raynor should have cared for him?" "He was a fine man," said Walkirk. "He was educated, good-looking, rich. He was young enough, but had been a bachelor too long, perhaps, and had very independent ways. It was on account of his independence of thought, especially on religious matters, that he and Miss Marcia Raynor had their difficulties, which ended in the breaking of the engagement. I am quite sure that she was a good deal cut up. As I said before, I do not think that she will consider marriage again." I took in a full breath of relief. Here Walkirk had told the little story of Brownson, and had said nothing of any subsequent engagement. Perhaps he knew of none. This thought was truly encouraging. "Perhaps you are right," I said, "she may know better than any of us what will suit her. Any way I ought to be satisfied; and that reminds me, Walkirk, that I have never expressed to you, as strongly as I wished to do it, my appreciation of the interest you have taken in my varied relations with Miss Sylvia Raynor, and for the valuable advice and assistance you have given me from time to time. For instance, I believe that your reluctance to have me go away from Tangent Island was due to your discovery that the island belonged to Sylvia's mother, and, therefore, there was some probability that she might come there." Walkirk smiled. "You have hit the truth," he said. "I have sometimes wondered," I continued, "why a man should take so much interest in the love affairs of another. When one engages an under-study, he does not generally expect that sort of thing." "Well," said Walkirk, "when a man engages as an under-study, or in a similar capacity, he often performs services, without regard to his duty and salary, simply because they interest and please him. Now it struck me that it would be a curious bit of romantic realism if two beautiful women, who on account of one man had become nuns in a convent, or what was practically the same thing, should both be taken out of that convent and brought back to their true life in the world by another man." "Two women"--I gasped. Walkirk smiled, and his voice assumed a comforting tone.
