"How did you get him tied up?"
"He got seasick and Joe knocked the gun out of his hand. Then we tackled him."
"Good work," approved Mr. Hardy. "I got a 'phone call from two Secret Service men this morning. It seems they've been trailing Paul Blum for some time and they were just about to arrest him when he made a bolt for liberty. They chased him down the street, but he disappeared, and the next thing they knew he was in your boat, heading for Bayport. They waved at you and tried to signal to you to come back—"
"So that's why the two fellows were running along the shore!" exclaimed Joe.
"But when you didn't turn back they telephoned to me to meet the boat and arrest him." Fenton Hardy turned to Chief Collig. "Did you find anything?" he asked.
The Chief straightened up, scratching his head.
"Not a thing. Nothin' but a dollar bill and some matches."
"No counterfeit money?" exclaimed Mr. Hardy, in surprise.
"Not a bit."
"That's strange. The detectives told me he had a big roll of bad bills."
