"Oh, it's my skull," she said. "I'm so glad to have it again. I shall want it when I go back to Philadelphia."

His face fell.

"I thought you weren't going back."

"Of course I shall go back."

"But if you are homesick?"

"I shall get over it."

"And the clinics?"

"Nobody ever died of a clinic—except the patient," she said grimly.

He stood looking at her steadily, and any one but Phebe would have known the meaning of his expression; but she was examining the skull intently.

"You are sure you don't want it any longer?" she asked.
