"Don't be angry, Richard," she said apologetically. "But please tell me what you do. Did you specialize in nerves after all?"

He shook his head. "No, Joan, I specialized in brain; I'm a surgeon, my dear."

"A great one, Richard?"

"Oh, I don't know; I'm fairly useful, I think."

His words roused a vague echo in her, something stirred feebly; the ghost of by-gone enthusiasm, called from the grave by the mere proximity of this man, so redolent of self-confidence and success. She moved uneasily, conscious that her thoughts were straying backwards. "Elizabeth——" she began, but checked herself, and at that moment a porter came up.

"Please, miss, the lady in twenty-four says will you come up at once, she's in bed."

"I must go; good-night, Richard."

"Wait a minute!" he said eagerly. "When shall I see you again?"

She hesitated. "I think I can get off for a walk at nine o'clock to-morrow morning; Mother won't be getting up until about twelve."

"I shall be waiting here in the hall," he said.
