“We went through the tower from top to bottom,” Frank replied. “It wasn’t any use. No one had been there. So then we thought Jackley might have been mistaken and that he had left the stuff in the other tower.”

“And Applegate let you search that as well?” and Fenton Hardy’s eyes twinkled.

“Not until we had told him our reasons. We told him about Jackley, and then he became enthusiastic and even helped us in the search. But we didn’t find anything.”

“Strange,” muttered the detective. “I know Jackley wasn’t lying. He had nothing to gain by deceiving me. Absolutely nothing. He was in real earnest if ever a man was. ‘I hid it in the old tower.’ Those were his words. He would have told more if he had been able. And what could he mean but the old tower of Tower Mansion? Why should he be so careful to say the old tower. Everyone knows the mansion has two towers, the old and the new.”
