Mrs. Hardy explained what she wanted and Frank and Joe were soon on their motorcycles again. When the boys reached the business section of Bayport they found that Jackley’s confession had already become known. The local radio station had broadcast it in the afternoon news program and people everywhere were discussing it.

Detective Smuff walked along the street looking as if he would bite the head off the first person who mentioned the case to him. When he saw the Hardy boys he glowered.

“Well,” he grunted, “I hear you got the stuff back.”

“I wish we had,” Frank said glumly.

“What!” the detective cried out, brightening at once. “You didn’t get it? I thought they said on the radio that this fellow Jackley had told your father where he hid it.”

“He did. But how did the news leak out?”

“Jackley’s door wasn’t closed all the time. One of the other patients who was walking by the room heard the confession and spilled it. So you didn’t find the loot after all! Ha-ha! That’s a good one! Didn’t Jackley say the stuff was hidden in the old tower? What more do you need?”

“Well, it wasn’t there!” Joe retorted hotly. “Jackley must have made a mistake!”

“Jackley made a mistake!” Smuff continued cheerfully. “It looks like the joke’s on you fellows and your father!” The would-be sleuth went on down the street, chuckling to himself.

When Frank and Joe returned home they found that Mr. Hardy had been in touch with Hurd Applegate and had convinced him that a more detailed search of the towers would be advisable.
