searchlights wonât pierce through this pea soup.â
âTheir best bet is to crisscross the bay and perhaps close in on the robbers,â Joe added.
âAnd for that a little boat is as good as a big one,â Frank said excitedly. âJoe, do you think the Sleuth is in good enough shape to take out?â
âItâs worth a try,â his brother assented.
Chief Collig nodded approvingly. âThe more boats we send out, the better our chances,â he said. âIâll dispatch the police cruiser, too.â
Frank and Joe swung onto their motorcycles and roared off the pier and along the Shore Road toward their boathouse as fast as they dared in the heavy fog.
Guessing they were near the private docks, the boys pulled off the road and parked. Each took a flashlight from the carrier of his motorcycle.
After a short walk they found their boathouse. Joe reached the small door and took out his key. He gave a cry.
âThe lockâs broken off!â
âWhat!â Frank exclaimed.
He swung the door open and beamed his flashlight inside the building.
The Sleuth was gone!
CHAPTER V
Dancing Gorillas
FOR A moment Frank and Joe stared at the empty boathouse unbelievingly. âIâll bet the bank robbers stole the Sleuth!â Joe exploded.
âIf they did,â Frank said with a grim smile, âthey may be surprised. That rudder is only temporarily repaired. It wonât last long.â
âLetâs go after them!â Joe urged. âWeâll call Tony to bring the Napoli.â
âOkay,â Frank said. âHeâll be at Callieâs now.â
The Hardys hurried to their motorcycles and headed back toward town. When they reached the piers, they stopped at a public telephone booth outside a warehouse. Joe dialed the call and returned after a short conversation.
âTony will meet us at the Coast Guard station,â he reported to Frank. âCome on!â
When the Hardys walked in they found that Chief Collig had turned the place into a temporary headquarters. He was questioning three bank tellers who had been brought there at the chiefâs request. One teller was giving his account:
âThe four men must have hidden in another part of the bank. Just after we closed tonight, the robbers rushed into the main room together. Three came to our cages and forced us at gun point to put all the money into their sacks, while the fourth went to the side door. Then they warned us to keep still, and backed out the door. Our vault custodian fired after their car, but had no luck.â
âCan you describe just one of the gang?â Collig asked wearily. âAny one that sticks in your mind? Was he short or tall? Fat or skinny?â
âI already told you,â the man said doggedly. âThey were all the same size.â
âBut blast it, man, thatâs impossible!â the chief exploded. âI donât have four identically built men on my whole force!â
âThey were all the same size,â the teller repeated, growing sullen. âThey wore masks.â
Shaking his head, Chief Collig turned from the teller. His eyes fell on Frank and Joe. âBack so soon?â he asked, surprised.
Frank told him about the stolen Sleuth. âThe bank robbers used a speedboat for their getaway,â Joe added. âIt might have been ours.â
âHas the cutter had any luck on the bay?â Frank asked.
âNothing yet,â the radio operator spoke up. âTheyâve been calling in every ten minutes.â
While Joe reported the theft of their boat to a Coast Guardman, Frank asked whether any dues had been found in the thievesâ car.
âNot even a fingerprint,â was Chief Colligâs answer. âWe checked on the vehicle, of course. It had been stolen in Northport.â
Just then Tony Prito entered the crowded station, exclaiming, âIt looks like a police convention outside, with all
