After a while he saw her emerge from Horse Camp Cañon and follow the road to her own place. Custer ran his fingers through his hair in perplexity. He was troubled not only because Shannon had ridden without him, after telling him that she could not ride that afternoon, but also because of the direction in which she had ridden—the trail of which he had told her that he thought it led to the solution of the mystery of the nocturnal traffic. He had told her that he would not ride it before Saturday, for fear of arousing the suspicions of the men he wished to surprise in whatever activity they might be engaged upon; and within a few hours she had ridden deliberately up into the mountains on that very trail.
The more Custer considered the matter, the more perplexed he became. At last he gave it up in sheer disgust. Doubtless Shannon would tell him all about it when he called for her later in the afternoon. He tried to forget it; but the thing would not be forgotten.
Several times he realized, with surprise, that he was hurt because she had ridden without him. He tried to argue that he was not hurt, that it made no difference to him, that she had a perfect right to ride with or without him as she saw fit, and that he did not care a straw one way or the other.
No, it was not that that was troubling him—it was something else. He didn’t know what it was, but a drink would straighten it out; so he took a drink. He realized that it was the first he had had in a week, and almost decided not to take it; but he changed his mind. After that he took several more without bothering his conscience to any appreciable extent. When his conscience showed signs of life, he reasoned it back to innocuous desuetude by that unanswerable argument:
“What’s the use?”
By the time he left to call for Shannon he was miserably happy and happily miserable; yet he showed no outward sign that he had been drinking, unless it was that he swung the roadster around the curves of the driveway leading down the hill a bit more rapidly than usual.
Shannon was ready and waiting for him. She came out to the car with a smile—a smile that hid a sad and frightened heart; and he greeted her with another that equally belied his inward feelings. As they rode up to the castle on the hill, he gave her every opportunity to mention and explain her ride, principally by long silences, though never by any outward indication that he thought she had aught to explain. If she did not care to have him know about it, she should never know from him that he already knew; but the canker of suspicion was already gnawing at his heart, and he was realizing, perhaps for the first time, how very desirable this new friendship had grown to be.
Again and again he insisted to himself that what she had done made no difference—that she must have had some excellent reason. Perhaps she had just wanted to be alone. He often had experienced a similar longing. Even when Grace had been there, he had occasionally wanted to ride off into the hills with nothing but his own thoughts for company.
Yet, argue as he would, the fact remained that it had made a difference, and that he was considering Shannon now in a new light. Just what the change meant he probably could not have satisfactorily explained, had he tried; but he did not try. He knew that there was a difference, and that his heart ached when it should not ache. It made him angry with himself, with the result that he went to his room and had another drink.
Shannon, too, felt the difference. She thought that it was her own guilty conscience, though why she should feel guilt for having risked so much for his sake she did not know. Instinctively she was honest, and so to deceive one whom she loved, even for a good purpose, troubled her.
