The incidents which led up to this were comparatively trivial—nothing more, indeed, at first than the sight of Miss Nowak and Cowperwood talking intimately in his office one afternoon when the others had gone and the fact that she appeared to be a little bit disturbed by Aileen’s arrival. Later came the discovery—though of this Aileen could not be absolutely sure—of Cowperwood and Antoinette in a closed carriage one stormy November afternoon in State Street when he was supposed to be out of the city. She was coming out of Merrill’s store at the time, and just happened to glance at the passing vehicle, which was running near the curb. Aileen, although uncertain, was greatly shocked. Could it be possible that he had not left town? She journeyed to his office on the pretext of taking old Laughlin’s dog, Jennie, a pretty collar she had found; actually to find if Antoinette were away at the same time. Could it be possible, she kept asking herself, that Cowperwood had become interested in his own stenographer? The fact that the office assumed that he was out of town and that Antoinette was not there gave her pause. Laughlin quite innocently informed her that he thought Miss Nowak had gone to one of the libraries to make up certain reports. It left her in doubt. What was Aileen to think? Her moods and aspirations were linked so closely with the love and success of Cowperwood that she could not, in spite of herself, but take fire at the least thought of losing him. He himself wondered sometimes, as he threaded the mesh-like paths of sex, what she would do once she discovered his variant conduct. Indeed, there had been little occasional squabbles, not sharp, but suggestive, when he was trifling about with Mrs. Kittridge, Mrs. Ledwell, and others. There were, as may be imagined, from time to time absences, brief and unimportant, which he explained easily, passional indifferences which were not explained so easily, and the like; but since his affections were not really involved in any of those instances, he had managed to smooth the matter over quite nicely. “Why do you say that?” he would demand, when she suggested, apropos of a trip or a day when she had not been with him, that there might have been another. “You know there hasn’t. If I am going in for that sort of thing you’ll learn it fast enough. Even if I did, it wouldn’t mean that I was unfaithful to you spiritually.” “Oh, wouldn’t it?” exclaimed Aileen, resentfully, and with some disturbance of spirit. “Well, you can keep your spiritual faithfulness. I’m not going to be content with any sweet thoughts.”
