"Esther, my dear, what is the matter with you? Have you no home and no friends, that you have to shed your tears in the public streets?" a slightly amused though sympathetic voice demanded.
Naturally Esther started. But the next instant she was shaking her head reproachfully. "Dr. Ashton, however in the world did you manage to discover me?" she demanded. "I am resting here for the special pleasure of being miserable all by myself. For I knew if I went back to the pension Betty and your mother would find me out. And the worst of it is that neither one of them understands in the least why I am unhappy. Betty is really angry and I am afraid that Mrs. Ashton thinks I am stupid and ungrateful."
Instead of replying, Richard Ashton picked up Esther's hand and slipped it through his own arm. He looked a good deal older than his companion. For he was now a graduated physician with three years of added foreign experience, and besides his natural seriousness he wore the reserved, thoughtful air peculiar to his profession. So his present attitude toward Esther Crippen seemed that of an older friend.
"I don't know what you are talking about or what dark secret you seem to be trying to conceal," he returned. "All that I do know is that I have been sent out to find you and that you are please to come home with me. Betty and mother have been expecting you to return from your music lesson for an hour. And Betty is so in the habit of getting herself lost or of mixing up in some adventure where she does not belong, that she is convinced a like fate has overtaken you. Then I believe that something or other has happened which she has not confided to me, but which she is dying to tell you. There are times, Esther, when I wish that our sister, Betty, was not quite so pretty. I am always afraid that some day or other these German students, whom she seems to have for her friends, will be involved in a duel over her. And if that happens I shall very promptly send her home."
Dick and Esther had now left the broad, park-like square and had turned into a narrower side street adjoining it. Ordinarily any such suggestion concerning Betty would have aroused Esther's immediate interest and protest. However, whatever was now on her mind was troubling her too much for her to pay any real attention to what Dick had just said. So they walked on for another block in silence, until finally Esther spoke in her old timid, hesitating manner, quite unconsciously locking her hands together, as she had on that day, long ago, of her first meeting with Richard Ashton.
"I am sorry to be so stupid and unentertaining. It was good of you to come and look for me," she began apologetically. "I wish I could stop thinking of what troubles me, but somehow I can't. For Betty will insist on my doing a thing that I simply know I shall not be able to do. And I do hate having to argue."
They were still some distance from the German pension where Dick, his mother and sister and Esther were boarding, so the young man did not make haste to continue their conversation, as he and Esther knew each other too intimately to consider silences.
"Look here, Esther," Richard Ashton finally began, "you know that Betty considers me the worst old gray-beard and lecturer on earth. So I am going to be true to my reputation and lecture you. Why do you allow yourself to be so much influenced by Betty? Don't you realize every now and then that you are the older and that the Princess ought to come around to your way of thinking? Why don't you tell her this time that you are right and she is wrong and that you won't hear anything more on the subject that is worrying you."
Esther laughed, swerving suddenly to get a swift view of the earnest face of her companion. How often he had befriended her, ever since those first days of shy misery and rapture when she had made her original appearance in the Ashton home, little realizing then that the Betty whom she already adored was her own sister.
"I am not really afraid of the Princess, you know, Mr. Dick," she replied, laughing and using an odd, old-fashioned title that she had once given him. "The truth is that if you were able to guess what I have on my mind you might also disagree with me. Because in this particular instance there is a possibility that Betty may be right in her judgment and I in the wrong."
