"It is all right, Miss Adams, of course," Betty murmured. "I am not in the least offended by your conjecture. It was natural enough under the circumstances, I think." And here Betty raised herself on one elbow, forgetting everything else in her earnestness. "Won't you tell me, please, Miss Adams, if it would have been so dreadful a thing if I had done what you supposed? Of course I should have let mother know, but otherwise I should not have thought anything of it. Why, it seems to me that it would have been much better had I had a companion on my walk. Because when I was such a goose as to catch my foot in a tangle of vines and tumble headlong, had Lieutenant von Reuter been with me he could have helped me home or at least let mother hear so that I need not have given so much trouble and uneasiness."
Miss Adams kissed the girl impetuously, failing to see that Polly was frowning at them both.
"Yes, dear, since you honestly wish to know, it would not have been wise," the older woman answered, "though I understood at the time that you might have done the thing without thinking. You know there is an old expression—and of course these old expressions bore us so that we are apt to forget how vital they are—that when we live in Rome we must do as the Romans so. I wish American girls would remember this adage a little better when they are traveling in Europe. You see, these old countries over here have had their customs much longer than we have had ours, and a walk with a friend would have meant nothing of any importance to you, but to them——"
"Margaret," Polly O'Neil broke into the conversation abruptly, "I don't mean to be rude in interrupting you. But there is one thing that Betty Ashton has never yet explained to my satisfaction or anybody else's, and I don't see why she should not do it now. Will you please tell me, Betty, whatever induced you to start off on such a journey by yourself? You must have known that the walk would take you several hours at least, even if nothing unforeseen had happened. Surely you had sense enough to know that your wandering around in a strange woods alone without anyone's knowing where you were would not be safe at any time or place. What made you do it?"
Betty bit her lips. It was true that she and Polly had never failed in the past in being absolutely honest with each other, nor had she ever hesitated to ask of Polly anything that she herself desired to know. Yet it was hardly fair that she should be asked this particular question before a comparative stranger. It had been difficult enough to make Dick and Esther accept her explanation as a reasonable one after several days of discussion. So what should she now answer Polly? For her friend's eyes were upon her with that queer searching gaze they sometimes wore, and her high cheek bones were flushed with determination—and something else.
"Answer me," Polly repeated firmly.
"Why, I thought I told you the other morning," Betty returned meekly. "I had no very special reason for taking the walk. I was just nervous and restless and kind of worried and all of a sudden as I started for home, why it seemed to me that I could not bear to go indoors so soon. And then I thought of the beautiful woods where we were together a while ago and I believed that if I could rest there for a little I should be——"
"Be what, Betty Ashton?" Polly demanded almost savagely. And then she shook her head sagely and with her arms about her knees relapsed into her old habit of rocking herself thoughtfully back and forth. "You need not try to explain anything further to me or to any one else for that matter. Your explanations are too absurd. Because if you don't know yourself what is the trouble with you, Esther and I both do. You are falling in love. You have not been like yourself for weeks! Why do you suppose that just now when I asked you a simple question that you should hesitate and flush? You went to that same old place in the forest alone just because you wanted to think about——"
But the Princess was now getting up from her place on the sofa and the other girl understood perfectly well her pretty air of offended dignity.
"Miss Adams," Betty began quietly, "it is growing late and if you don't mind will you ask your maid to send for my carriage. I have had a lovely day with you. Thank you for having asked me." And as she started limping into the other room for her wraps it was the older woman who slipped her arm affectionately about her, in the meantime frowning at Polly with more displeasure than she had ever before shown.
