"I can add two and two, anyhow," asserted Jerry.
True to Jerry's prediction, three curious young women stood grouped in front of Marjorie's locker, impatiently awaiting her arrival.
"Wait until we are outside, girls. I'll be ready in a jiffy." Marjorie slipped into her raincoat and pulled her blue velour hat over her curls. "We can't talk here. Miss Merton is likely to wander down, and then you know what will happen."
"Oh, bother Miss Merton!" grumbled Jerry. "I can stand anything she says and live. Still, I don't blame you, Marjorie. It tickles her to pieces to get a chance to snap at you. Now if Mignon La Salle wanted to sing a solo in front of her locker at the top of her voice, Miss Merton would encore it."
Susan Atwell giggled. "I can just hear Mignon lifting up her voice in song with Miss Merton as an appreciative audience."
The quartette thoughtlessly echoed her merriment. So intent were they upon their own affairs that they did not notice the two girls who were almost hidden behind an open locker at the end of the room. The black eyes of one of them gleamed with rage. She turned to the fair-haired girl at her side with a gesture which said more plainly than words, "You see for yourself." The other nodded. Mignon laid a finger on her lips. Then noiselessly as two shadows they flitted through the open door without having been observed by the group at the other end.
For the moment Marjorie's back had been turned toward that end of the room. She whirled about just too late to see Mignon and Mary as they hurried away. Unusually sensitive to impressions, she had perhaps felt their presence, for she asked abruptly, "Girls, have you seen Mary? She can't have gone, for I'm sure I left the study hall before she did. I ought to wait for her, but I don't know what to do." She glanced irresolutely about her. Then, her pride again coming to her rescue, she said, "Never mind. Suppose we go on. Perhaps I'd better not try to see her now, because I must tell you my plan and I—well—I can't—if she is with us."
Muriel Harding elevated her eyebrows in surprise. Of the four girls who had received Marjorie's notes, she alone had no suspicion of the purpose which had brought them together.
Five pairs of bright eyes scanned the street across from the school building as the little party came down the wide stone steps.
"The coast is clear," commented Jerry. "Now do tell us what's the matter, Marjorie. No, wait a minute." Jerry fumbled energetically in a small leather bag. "Hooray! Here's a real life fifty-cent piece! I can see it vanishing in the shape of five sundaes, at ten cents per eat. We can't go to Sargent's. They cost fifteen——"
