It was Edith Whalen.
Bet wanted to go herself and confront the girl, but thought better of it and kept to the plan she and Mr. Sills had made. She ran to the office and called the principal.
Edith had tiptoed into the classroom, selected the book she wanted and turned to go. At the door she met Mr. Sills.
"I would like to see you in the office, Edith," he said quietly.
Edith clutched the book and quickly hid it under her coat, wishing she could find a place to drop it when Mr. Sills was not looking. But there was no chance to get rid of it.
When they reached the office, the principal said quietly, "Edith, give me the book you have there."
The girl hesitated. He extended his hand.
"It's the Latin key from Miss Owens' desk. I want it." Then as Edith hesitated still, he demanded: "Pass it over at once."
"Now sit down here and tell me the whole story. Why did you put that book in Kit Patten's desk?"
Edith started to deny that she had done so, then decided to be perfectly silent.
