The professor had quite neglected to consider Olive.

"I have told Olive," went on Aunt Caroline, "that Mrs. Spence had received news of her father which was far from satisfactory and that she had left for Vancouver by the early morning train. The morning train is the only one she could have left by, isn't it?"

"Yes."

"Then that's all right. I also let Olive know, indirectly, that you were remaining behind to attend to a few matters. After which you would follow."

Admiration for this generalship pierced even the deep depression of the professor.

"Does John know where she is?" pursued Aunt Caroline.

"No."

"Then she has gone home to her father. She said something the other day which puzzled me. I can't remember just what it was but she seemed to have some fatalistic idea, about her old life having a hold upon her which she couldn't shake off. Pure morbidity, as I pointed out. But she has gone back. I have a feeling that she has."

"You may be right, Aunt. It will be easy to find out. If I can make the necessary inquiries without arousing gossip. There was nothing in the mail—for me?"
