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."
