“Oh, I hope Terry and Sim will come back with me and see this for themselves,” she thought. “How wonderful that I have made this discovery! I need not wire Dad for that money after all. I’m sure,” she tried to convince herself, “that I am right. Quite sure!”

There was no time to be lost. Supper would soon be served and the three from 513 dared not be absent from their places at the table very long. Nor would they want to be. Appetites were remarkably keen at the college, in spite of all the mystery and excitement and notwithstanding the eating that was done between meals.

As Arden approached the main building which loomed up out of the fog like some dream castle, she called on her childhood friend, the “good fairy.” She murmured: “Good fairy, please don’t let us get caught, and for a wish, I wish that Terry and Sim will come back with me right away!”

It seemed the good fairy did not entirely desert her child, for, as Arden started up the stairs, she met her two chums coming down.

“Terry! Sim! I’ve the most exciting thing to tell you!” Arden gulped and continued: “Come outside a moment.”

“Good heavens! You look as if you’d seen a ghost! Take a breath—or something—before you pass out!” advised Terry, a little incredulous.

“Well, tell us, Arden!” Sim begged, wringing her hands in simulated melodramatic fashion. “This suspense is awful! It’s making an old woman of me!”

“I don’t want anyone to hear,” Arden confided. “Can’t you step outside for a few seconds? You won’t be cold. I want you to do something for me.”

Sim and Terry looked at each other.

“Better humor her, Sim. She might turn violent. Come on,” Terry said in an exaggerated attempt at soothing a patient.
