"Irma!" cried Marjorie, as she glimpsed a laughing face. "Oh, it's too wonderful!" She wound two penitent arms around Constance and kissed her. "I guess that will settle Mignon," commented Jerry, in triumph. "It is a shame, but I suppose your butterfly pin is really lost. Constance will tell you the history of hers." "I wish the bracelet problem could be solved, too," sighed Constance. "Jerry tells me that Mignon is going to accuse me of taking it when I go back to school. How can she be so cruel? I don't remember seeing it in the dressing-room on the night of the Weston dance." "But I do!" called out a positive voice that caused them all to face the intruder in astonishment. A slim, pale-faced girl, dressed as a shepherdess, emerged from behind a curtain which hung in a little alcove at one end of the dressing-room. "Please excuse me for listening," apologized the girl. "I was standing here looking out of the window when you girls came in and began to talk. Before I could make up my mind what it was all about I heard Miss Stevens talking about Miss La Salle's bracelet and the Weston dance. Did Miss La Salle accuse you of taking her bracelet that night?" she asked, her eyes upon Constance. "Yes," began Constance, "she----" "Miss La Salle is the real thief," interrupted the girl, dryly. "I saw her take off her bracelet and lay it on the dressing table. I saw her come and take it away after Miss Stevens left the room. I had to catch the last train home that night. You know, I don't live in Sanford, and I was sitting over in one corner of the dressing-room behind a chair putting on my shoes. Neither Miss Stevens nor Miss La Salle saw me. I wondered what Miss La Salle meant by doing as she did, but I never understood until this minute. I'm glad I happened to be there that night and I'm glad I happen to be here now. If there is likely to be any trouble, just send for me. I'm Edna Halstead, of the junior class." The four girls had received this rapidly repeated information with varying degrees of amazement. It was Marjorie who first sprang forward and offered her hand to Edna Halstead. "It is the last word we needed to clear Constance," she asserted, joyously. "Will you go to Miss Archer with us on Monday?" "I should be glad to do so. I never could endure that La Salle girl," was the frank response. "We'll go together," planned Jerry. "Every one of you meet me in Miss Archer's living-room office on Monday morning before school begins." "I must go home now," demurred Constance. "I don't wish anyone to know that I've been here." "Not even Laurie?" asked Marjorie, slyly. "He spoke of you to-night." Constance smiled. "You may tell him after the 'Home, Sweet Home' waltz." "There goes the music for the ninth dance," informed Jerry, who had stepped to the door. "Oh, gracious, I promised this dance to Hal! I can't go. I simply must hear about the pin, Connie."
