Fox had been looking out of the window. He turned. "Mrs. Ladue," he asked suddenly, "will you go sleighing with me to-morrow? It will be about my last chance, for I go back when Sally leaves the Mortons'."
"Oh," cried Sally, "why not me, too? And Henrietta?"
Fox smiled at her. "There's a reason," he said. "I'll take you when the time is ripe. I have something to show your mother and we have to go after it."
"Can't you get it and show it to me, too?"
Fox shook his head. "I'm afraid not. It isn't mine, for one thing."
"Oh," said Sally, her head in the air. "And I suppose you'll go in the morning, when I'm in school."
"That might not be a bad idea. We might be followed. Can you go in the morning, Mrs. Ladue?"
She laughed and nodded. She would go at any time that suited him.
So it chanced that Fox and Mrs. Ladue started out, the next morning. Fox drove along Apple Tree Street and turned into another street.
"Isn't this Smith Street?" asked Mrs. Ladue doubtfully. "Where are we going, Fox?"
