of the old tower quickly spread, and throughout the day they were subjected to many caustic and sarcastic inquiries on the part of friends and acquaintances alike. They took all these remarks in good part, although they did not enjoy their sudden prominence.
"Never mind," said Frank, "we'll show them yet."
"I hope they find that stuff when they search the towers again," added Joe. "Then the people will have to eat crow. It'll be our turn to laugh."
"Yes," agreed Frank; "but just now our laughter seems to be in a far-distant future."
When they returned home they found that Fenton Hardy had been busy in the meantime and had convinced Hurd Applegate that a thorough search of the towers would be advisable. True, he had not accomplished this without a great deal of opposition on the part of Adelia and without misgivings on the part of Hurd Applegate himself, who had by that time come to the conclusion that Robinson had indeed been mixed up in the affair all along.
In this conviction he was sustained by Chief Collig, who had paid a call at the Applegate home as soon as Collig had told him of the vain search of the towers.
"The chief says Robinson is behind it, and I'm beginnin' to think he's right," said Applegate.
