“What kind of a hat did he wear?” asked Julia with interest. “Was it large and drooping, with yellow roses?”

“The very hat. But I never knew you to take so much interest in a mere hat!”

“And was the cape a black one, with a chenille collar?”

“Yes, I think so.”

“Then he was here at the play. I wondered who she was. But why in the world did he do it?”

One afternoon soon after this, as Polly and Ruth loitered in the hall they noticed a young man entering the Secretary’s office.

“He’ll find no one there,” said Polly, “for I’ve just been in myself.”

Stepping out of the office door, the visitor happened to see Annabel Harmon crossing his path, and he stopped her, apparently to ask a question.

“I wonder who he is,” said Polly. “Annabel will think herself in luck if he asks her to show him the building. She loves to act as guide, philosopher, and friend to strangers.”

Apparently some such duty had fallen on Annabel, for she and the stranger ascended the stairs toward the Library.
