Peter shook his head. "He simply disappeared. I cannot guess why. Maybe he, too, will show up tomorrow."

"Peter, who rang the bell?"

Peter flushed under his darkened skin. "I think Father Albanel saw Mona and me in the moonlight. He always loved to wander about late at night, when the moon was bright."

Simon's gaunt face broke into a strange smile.

"It wasn't Father Albanel who rang the bell," he said.

"No?" Peter looked at him sharply. "Then it was you, Simon! You saw us?"

"No. I was asleep—sound asleep. But I know who rang the bell. It was Carter!"

A little thrill leaped through Peter. "It is impossible. Carter would not have run away from me for that. Besides——"

He did not finish, for Simon had risen and was looking out through the window in a way that puzzled him.
