The prospective dinner at Vinton's at which Ruth Denton and Arline Thayer were to be guests of honor drove the unpleasant incident of the morning from Grace's mind for the time being. She had determined to keep her interview with Miss Duncan a secret from her friends. If it had involved only herself, she might possibly have told Anne of it, but since it concerned some one else, Grace's fine sense of honor forbade her making even Anne her confidant in the matter. She could not help speculating a little concerning the identity of the other girl. She had not the remotest idea as to who she might be. Whoever she was, she could not have realized what a dishonorable thing she had done, was Grace's charitable reflection. She wondered what Mabel would think when Miss Duncan asked her to identify the theme as the one Grace had written during that evening in Holland House.

"I'm going to stop thinking of it for the rest of the day," declared Grace half aloud, as she dressed for dinner late that afternoon. She started guiltily, glancing quickly to where Anne sat mending a tiny tear in her white silk blouse. Anne, who was fully occupied with her mending, made no comment. She was so used to Grace's habit of thinking aloud that she had no idle curiosity regarding her friend's thoughts. Whatever Grace wished her to know she would hear in due season.

"Miriam and Elfreda are not going with us, you know," said Grace as they were about to leave their room.

"I didn't know it," commented Anne. "Why did they change their minds?"

"Miriam thinks you and I can do more toward restoring peace without her and Elfreda. She suspects that Ruth will satisfy Arline's curiosity and at the same time appease her wrath by telling what she refused to tell that other night, provided there are not too many listeners."

"What a wise girl Miriam is!" exclaimed Anne admiringly. "I never thought of that."

"Nor I," admitted Grace, "until she mentioned it. Then I saw the wisdom of it."

"Where are we to meet Ruth and Arline?" asked Anne. "Suppose both of them arrive at Vinton's before we do?"

"I thought of that, too," chuckled Grace, "so Arline is to come here, and Ruth is to wait for us at Vinton's. They can't possibly meet until we are there to manage matters. Arline ought to be here by this time. Shall we go downstairs and wait for her?"

"There's the door bell now," said Anne. "That must be Arline."

Her supposition proved correct. Just as they reached the foot of the stairs the maid admitted the fluffy-haired little girl.

"Hello!" she called merrily. "I'm strictly on time, you see."

"So are we," smiled Anne. "Shall we start at once?"

"Yes, indeed," emphasized Arline. "I'm starved. I wasn't prepared in Greek to-day, and rushed through my luncheon in order to snatch a few minutes' study before class. I had my trouble for my pains, too. The bell rang before it was my turn to recite. Wasn't that fortunate?"

"I should say so," agreed Grace. "If it had been I, Professor Martin would have called on me first. You were born lucky, Daffydowndilly."

"I don't think so," replied Arline gloomily. "I have all kinds of miserable, unpleasant things to bother me."

Anne and Grace exchanged significant glances behind the little girl's back. There was a chance for the success of their scheme. Arline was evidently unhappy over her cavalier treatment of Ruth.

During the short walk to Vinton's all mention of Ruth's name was tacitly avoided. Arline chattered volubly about the reception. She had not enjoyed herself particularly. She had taken a freshman by the name of Violet Darby, who lived on the top floor of Morton House. She was considered the freshman beauty.

"Oh, I remember her!" exclaimed Grace. "Gertrude Wells introduced me to her. I asked for a dance, but her card was full to overflowing. She is beautiful. She has such wonderful golden hair, and her brown eyes are in such striking contrast to her hair and fair complexion. She is awfully popular, I suppose."

"Yes, the Morton House girls are all rushing her. I was surprised to think she accepted my invitation," returned Arline.

"I don't think that was so very surprising," declared Grace bluntly. "Arline Thayer is also a Morton House favorite."

"Violet is the reigning favorite just at present," rejoined Arline. "It's her fatal beauty. She is a very nice girl, though. Not a bit snobbish or conceited. Everyone in the house likes her. You must become better acquainted with her."

"Here we are at Vinton's," announced Grace. "I ordered one of the alcove tables reserved for us."

As they made their way to the alcove a girl rose from her seat in the shadow to greet them. It was Ruth, and as Arline caught sight of her her baby face grew dark. "How dared you?" she asked accusingly, turning toward Grace. "You know we are not friends. I don't wish to see her. I'm going straight home. I suppose she planned all this. She has tried to make up with me, but I shall never again be friends with her."

"Please listen to me, Arline," began Grace, taking the angry little girl by the arm and pulling her gently toward the alcove. Ruth had risen from the table, a look of mingled pain and bewilderment on her face.

"I didn't know Arline was to be here," she said tremulously. "Please tell her I didn't know it." She turned appealing eyes toward Grace.

"Suppose we sit down at our table and talk over this matter," suggested Grace, in her most casual manner. Her calm gray eyes rested first on Ruth, then traveled to Arline, who hesitated briefly, then with an angry shrug of her shoulders seated herself in the nearest chair. Grace motioned Anne and Ruth to their chairs, then seating herself she said gently: "Now, children, suppose we clear up some of these doubts and misunderstanding by holding court? I am going to be the prosecuting attorney. Anne can be the counsel for the defense. Arline can borrow her first, then Ruth can have her. When all the evidence is in I shall appoint myself as judge and jury. It means a great deal of work for me, but the law must take its course. I, therefore, summon you both into court."
