So far as the newcomers could learn Betty had left the cottage at about eleven o'clock in the morning to go to the village of Waldheim for the work with the Camp Fire club which she had recently organized. But instead of waiting for Polly to accompany her after their regular custom she had seemed restless and in a most unusual hurry, and when Polly happened to be ten or fifteen minutes late for their appointment, Betty had gone off without her, taking their little German maid-of-all-work as her companion for the walk.

Afterwards the maid had reported that das Fräulein had arrived safely at the school and had joined her German friend, who was learning the business of a Camp Fire guardian. Later the girl had returned home expecting Betty to appear at lunch time; but it was now half-past five and no word had come from her, notwithstanding that several hours before Mrs. Ashton herself had gone into Waldheim and learned that Betty had presumably started for the cottage a short time after noon.

She had no other acquaintances in the village to detain her, so that the mystery of her disappearance was complete. There were, however, several persons who claimed to have seen her leaving for home at about the accustomed hour.

Naturally for the first few moments after their arrival both Dick and Esther were more astounded and stunned over the Princess' unaccountable behavior than frightened. For it seemed impossible to imagine that anything serious could have happened to her. Yet ten minutes later both the girl and man were suffering from even greater apprehension than Mrs. Ashton had endured. For whatever had induced Betty to attempt the walk from the village to their cottage alone? Of course the neighborhood in which they were spending the summer was presumably a quiet and peaceful one; still the two older women and Richard Ashton had objected to any one of the girls going any distance from their homes without companionship. And Betty was ordinarily obedient to her mother's slightest wish, fearing to cause her anxiety.

Rather helplessly Richard Ashton turned toward Margaret Adams, as a stranger is oftentimes of more use in an emergency of this kind than a member of one's own family.

"I had better go down to the village at once, don't you think?" he suggested. "There must be police, some one to whom I can appeal for assistance. If we were only in our own country one would know so readily what to do."

"I will go with you, Dick," Polly answered, beginning to put on her hat and light wrap. "No, Esther dear, you look tired to death already and some one must stay here with Mrs. Ashton and Margaret. In all probability Betty will return before we are able to get back."

Esther had gone to their front door to look out, but at Polly's words she returned and faced Mrs. Ashton.

"Don't you think we had best find Lieutenant von Reuter and ask his assistance?" she volunteered. "We know no one in this part of the country who would have so much influence. If Betty has lost her way, if the woods have to be searched, why no one could give us such valuable aid."

Mrs. Ashton's expression changed; she looked much relieved. "Esther dear, you are such a comfort. Why in the world did I not think of that idea at once? Lieutenant von Reuter is such a friend of Betty's and of mine that I am sure he will tell us what to do, even if he is unable to discover Betty himself." She put her hand on her son's shoulder, for Dick Ashton was growing more and more stern and uneasy. "Don't you think you had best drive up to the castle and see him yourself? Or if you could telephone that would be quicker."
