There was one development in connection with all of this of which Cowperwood was as yet unaware. The same day that brought Edward Butler the anonymous communication in regard to his daughter, brought almost a duplicate of it to Mrs. Frank Algernon Cowperwood, only in this case the name of Aileen Butler had curiously been omitted. Perhaps you don’t know that your husband is running with another woman. If you don’t believe it, watch the house at 931 North Tenth Street. Mrs. Cowperwood was in the conservatory watering some plants when this letter was brought by her maid Monday morning. She was most placid in her thoughts, for she did not know what all the conferring of the night before meant. Frank was occasionally troubled by financial storms, but they did not see to harm him. “Lay it on the table in the library, Annie. I’ll get it.” She thought it was some social note. In a little while (such was her deliberate way), she put down her sprinkling-pot and went into the library. There it was lying on the green leather sheepskin which constituted a part of the ornamentation of the large library table. She picked it up, glanced at it curiously because it was on cheap paper, and then opened it. Her face paled slightly as she read it; and then her hand trembled—not much. Hers was not a soul that ever loved passionately, hence she could not suffer passionately. She was hurt, disgusted, enraged for the moment, and frightened; but she was not broken in spirit entirely. Thirteen years of life with Frank Cowperwood had taught her a number of things. He was selfish, she knew now, self-centered, and not as much charmed by her as he had been. The fear she had originally felt as to the effect of her preponderance of years had been to some extent justified by the lapse of time. Frank did not love her as he had—he had not for some time; she had felt it. What was it?—she had asked herself at times—almost, who was it? Business was engrossing him so. Finance was his master. Did this mean the end of her regime, she queried. Would he cast her off? Where would she go? What would she do? She was not helpless, of course, for she had money of her own which he was manipulating for her. Who was this other woman? Was she young, beautiful, of any social position? Was it—? Suddenly she stopped. Was it? Could it be, by any chance—her mouth opened—Aileen Butler?
