Joe.
âAnd hereâs a chink. Iâll shine my light in while you look through the hole.â
Joe watched the slender beam shift around the dark room. âEmpty,â he declared, disappointed. âLetâs look for more of Chetâs or Biffâs belongings.â They searched the sand around the shanty, but found nothing.
âLetâs hide in the deserted shack again,â Frank suggested. âIf Sutton comes back with any of his pals, we may overhear something important.â
Patiently the young detectives waited and watched, but their quarry did not return. Frank consulted his watch. âItâs almost midnight. Maybeââ
âSh!â Joe interrupted. âListen!â
They heard footsteps and saw a dark figure approaching Suttonâs shanty. The stranger knocked several times. Finally a neighbor opened his door. âYou lookinâ for Sutton?â he asked.
âYes,â replied the unknown caller. âAll I know is he went off in a car with a dark-haired fellow. I heard Sutton say he wouldnât come back tonight.â
Without a word the caller disappeared into the darkness. The door to the shack slammed shut.
âThatâs that,â Frank said in disappointment. âLetâs go back to town and report to headquarters.â
âYou bet. Frank, do you suppose Chet and Biff were here but have been taken away?â
âItâs a good guess.â
The boys covered the mile of beach to their boat, quickly pulled off the improvised camouflage, and launched her. Frank headed down the coast toward Bayport and the Hardy boathouse. When the boys had debarked, they donned their street clothes again. Carrying their burlap bags, they emerged from the boathouse and mounted their motorcycles. It was well past midnight.
When the Hardys reached police headquarters, they were amazed to see Chief Collig in his office. He looked tired and somewhat dejected.
âIâve been working night and day on the bank robbery case and the mystery of your friends,â he said. âIâm afraid that the boys have been kidnaped.â
âThatâs what we fear,â Frank said. He showed the gorilla head mask and sleeve of Chetâs costume and told of the boysâ run-in with Sutton.
âIâll send men out there to make a thorough search,â Collig said.
âWeâll go with them!â Joe volunteered eagerly.
âWeâd better not,â Frank countered. âOnce the men at Shantytown see us with the police, we wonât be able to work under cover there.â
Regretfully, Joe agreed.
Chief Collig rose, strode around the desk, and clapped each of the young sleuths on the shoulder. âThanks, boys! Youâve brought in the first two leads Iâve had on this case,â he said. âIf we find Chet and Biff, Iâll call you at once.â
Frank and Joe hurried home through the silent streets. When they let themselves into the house, they saw a light in Fenton Hardyâs upstairs study. Frank knocked.
âCome in,â called the detective. When his sons entered, he pushed aside some papers on his desk. âWhat did you find out today?â
He leaned back in his big leather chair and listened carefully as his sons gave an account of their dayâs progress.
When it was finished, their father said, âIf Collig doesnât find Chet and Biff in Shantytown tonight, and they were kidnaped, their parents should receive ransom notes soon.â
âPerhaps they will come tomorrow,â Frank suggested. He turned to his father. âDo you think Chet and Biffâs disappearance could have anything to do with the bank robbery?â
âItâs possible.â
âIn that case, maybe youâd let us give you a hand on the bank robbery case, Dad.â
âAs a matter of fact,â the detective replied, âif Collig hadnât offered you the Shantytown problem, I
