Doctor Allday relapsed into silence.

"May I at least ask," she went on, "if you know anything of persons--" She paused, discouraged by the cold expression of inquiry in the old man's eyes as he looked at her.

Emily named the landlady of the inn at Zeeland: she could now place the right interpretation on Mrs. Rook's conduct, when the locket had been put into her hand at Netherwoods. Doctor Allday answered shortly and stiffly: he had never even seen Mrs. Rook. Emily mentioned Miss Jethro next--and saw at once that she had interested him.

"What do you suspect Miss Jethro of doing?" he asked.

"I suspect her of knowing more of my father's death than she is willing to acknowledge," Emily replied.

The doctor's manner altered for the better. "I agree with you," he said frankly. "But I have some knowledge of that lady. I warn you not to waste time and trouble in trying to discover the weak side of Miss Jethro."

"That was not my experience of her at school," Emily rejoined. "At the same time I don't know what may have happened since those days. I may perhaps have lost the place I once held in her regard."

"I hope and trust I am wrong," Emily continued; "but I fear my aunt had something to do with Miss Jethro's dismissal from the school--and in that case Miss Jethro may have found it out." Her eyes, resting on the doctor, suddenly brightened. "You know something about it!" she exclaimed.
