"You will say nothing about this to-night. I wish you to come to my office to-morrow morning at ten. Do you understand?"

"Yes, ma'am," answered Molly, reverting to her childhood's method of answering older people. She climbed the ladder in a dazed sort of way. It was more difficult than climbing down, but at last she scaled the window sill and jumped into the room. Judy was still sitting on the floor, holding her temples. Perhaps it had been only five minutes, but it seemed like a thousand years. However, she felt little sympathy for Judy, bruised temple or not.

"Get up from there and get to your bed," she whispered. "And I want to hear from you exactly what you were doing down there and where you got that ladder."

"The rope ladder belonged to Anne White," Judy answered in a stifled voice. "I borrowed it to win a wager from Adele. Of course, I don't mean to blame her, but she teased me into it. It was silly, I know, looking back on it now."

"What was the bet?"

"She bet that I would be afraid to climb down that ladder at midnight when the ghost is supposed to walk. I was simply to climb down, touch the ground and climb back again."

"Idiots, both of you," said Molly furiously.

"I know it, and I am sorry now," said the penitent Judy, "but fortunately no harm has been done except to my silly head, which needed a good whacking, anyhow."

"No harm," thought Molly angrily. "I wonder what's going to happen to me to-morrow. One of us will be expelled, I suppose. Miss Walker is already down on Judy."

"Thank you for coming down to me, Molly, dearest."
