The burly pilot's expression became ugly. “Don't get smart with us, kidl We'll ask the questions!”
“I'll bet they're phonies!” Frank cried out.
The men heard him. “Shut up or we'll clap you all in irons!” one threatened. As the boats touched sides, he vaulted over the gunwale.
Joe greeted him with a stiff-hand jab before the man could find solid footing on the
Hai Hau's
deck. Taken off balance, he toppled backward into the water. He came up spluttering and cursing. The helmsman shouted dire threats at the boys.
“Now's our chance!” Joe yelled. “Give 'er the gun, Tony!” He threw the helm hard over.
Tony revved the outboard and the junk spurted away from the speedboat. Its wheelsman was too concerned with rescuing his partner to give chase.
Biff chuckled and pumped Joe's hand. “Nice going, pal!”
The boys hooted with laughter as they watched the man in the water being hauled into the speedboat, drenched and dripping. He looked balefully at the boys.
“You won't get away with this!”
His angry bellow carried across the water. He and his pal made no attempt to go after the boys, evidently realizing that they stood little chance against the
Hai Hau's
husky and determined crew.
“Wow! This is more excitement than I bargained for!” Jim Foy said. “Are you fellows sure those guys weren't real coastguardmen from the Bayport station?”
“We'll soon find out!” Biff declared.
He warmed up the transmitter again and tuned in the Coast Guard station frequency. All of the crew were much relieved when the base's radio operator assured them that no harbor patrol boats had been ordered to pick up unregistered craft. He also said that the lieutenant in charge would send out a launch at once to hunt for the trouble-makers.
“I wonder where those fakers got their uniforms?” Tony mused.
Frank shrugged. “Stole them probably. What I'd like to know is why everyone's so anxious to get hold of this junk.”
“Maybe all the guys we've had run-ins with are members of the same gang,” Joe conjectured.
Biff offered another theory. He suggested that the two fake coastguardmen might be cronies of Clams Dagget. “Maybe Clams hired them to keep us from starting our boat business,” Biff said. “You told us, Frank, that he sure was mad when he came to your house.”
“That's right.”
The
Hai Hau
returned to Bayport without further incident, and was tied up at the pier. Jim Foy said he must leave as he had a job to do for his father. The other four boys remained for a while, talking over their plans. Tomorrow was to be the opening day of their passenger service to Rocky Isle.
“Let's keep our fingers crossed!” Tony said with a grin as the meeting broke up.
“Don't worry,” Frank replied confidently. “I'll bet we get a full boatload every trip!”
Biff and Tony, who had chores to attend to, drove off in Biff's jeep. “See you tomorrow, fellows!”
“What'll we do now?” Joe asked his brother.
“Let's grab a hamburger,” Frank said. “I'm starved.”
“So am I. But first I want to phone the Coast Guard and find out if they've picked up those two fakers.”
The brothers went into a nearby restaurant which had a pay telephone booth and made the call. The two men had not been caught.
As the Hardys perched themselves on stools, Joe suggested, “What say you and I try to trace those phony coastguardmen? Maybe we can spot their boat. After all, we got a good look at it.”
“Smart idea! We'll take the
Sleuth.”
The boys finished their hamburgers and hurried to the boathouse where they kept their motorboat. Minutes later, they were cruising along the shore of Barmet Bay. They went the full length of the three miles, first inspecting the north side, then the south. There was no sign of the speedboat anywhere.
“Let's try the ocean,” Frank urged.
Leaving the harbor mouth, the Hardys turned northward along the coast. The ocean was as quiet as a pond. From time to time the brothers hailed fishing boats and other small craft to inquire about the speedboat. None of the skippers they questioned had sighted it, and the boys did not spot the craft hidden anywhere along the rocky, indented shoreline.
“Looks as if we're out of luck,” Joe grumbled.
Frank was keeping binoculars trained along the coast. “Let's try south of the bay,” he suggested.
“Okay. Let's go!” Joe swung the
Sleuth
around, leaving a frothing wake.
As it passed Rocky Isle to starboard, a small cabin cruiser crossed their bow. The man at the wheel waved to them. Frank shouted a description of the speedboat and asked if he had seen it.
“Sure, about ten minutes ago,” the yachtsman called back. “Heading over that way!”
He indicated a sandy stretch of beach half a mile beyond the harbor mouth.
“Thanks!” The boys waved back.
“A break at last!” Joe muttered. He increased speed and the
Sleuth
lunged ahead, its bow lifting clear of the water.
As they neared the beach which the yachtsman had pointed out, the boys switched places. Frank took the wheel.
“Hey, this is where Clams Dagget lives!” Joe remembered suddenly. He trained the binoculars on the shore, picking out Dagget's shack. “Frank!” he yelled excitedly. “I see those two men who pretended to be coastguardmen. They're standing in front of the shack, talking to Clams!”
Frank gunned the motorboat shoreward. As it beached in the shallows of an inlet the boys leaped out and ran toward the shack.
At that instant their quarry sighted them. Breaking off the conversation with Clams, the two men dashed into the tall cattails behind the shack.
“After those fakers!” Joe shouted to Frank.
The marshy ground sloped upward into scrubby underbrush, willows, and sumac. Frank and Joe could hear the men plunging forward, but soon lost sight of them. The boys were finally forced to give up.
“What luck!” Joe growled. “We almost had 'em!”
“Let's see what Clams has to say about them,” Frank suggested grimly.
Dagget was lounging in front of his shack, whittling a piece of wood. He appeared unconcerned as the two boys walked up to him.
“Who were those guys?” Frank demanded.
“What guys?”
“The ones we were chasing.”
Clams shrugged. “How should I know?” He began whistling airily as he continued work with his pocketknife.
“You'd better think hard!” Frank warned him. “Those fellows areâ”
He broke off as a motor roared in the distance. A second later the boys saw their quarry's speedboat race from a nearby cove. It headed northward.
Joe clenched his fists in futile rage. “No hope of catching them with that kind of a start! But I can notify the authorities on the
Sleuth's
radio. Wait here,” he told Frank, and dashed back to the motorboat.
The young detective pressed the button for the Coast Guard frequency. He reported having seen the impersonators and that they had taken a northerly route in their escape.
“Let's go after those fakers!” Joe urged
Meanwhile, Frank had been quizzing Clams Dagget. When he found him unwilling to talk, Frank flushed with anger.
“Listen, ClamsâI'm warning you. Those two guys you were talking to just committed a federal offense.”
“What!”
The old beachcomber's mouth dropped open in a look of alarm.
“You heard me. They're impersonating members of the United States Coast Guard. What's more, they tried to board our junk and take over,” Frank added. “That could be attempted piracy.”
“I don't know nothin' about âem,” Clams Dagget whined. “Never even seen 'em before. That's the truth!”
“Then what were you talking to them about? You were sure acting chummy!”
“They said they wanted me to do a job forâem,” Clams replied. “I don't know what. You and your brother came along and scared 'em off before they got a chance to explain.”
Presently Joe returned and questioned Clams further, but finally both boys decided he was telling the truth. Boarding the
Sleuth,
they returned to Bayport.
It was almost seven o'clock when Frank and Joe arrived home. They found a note from Aunt Gertrude on the hall table. It said:
I feel much better and am going out. Dr. Montrose is a good physician. He did not talk about stocks and I had no chance to bring up the subject.
Phone Chet Morton's mother as soon as you get in. She has called twice.
Frank frowned. “I wonder what's up?”
He dialed the Morton's number. A woman's voice answered almost immediately.
“This is Frank Hardy, Mrs. Morton. Iâ”
“Oh, thank goodness you got my message!” Mrs. Morton sounded frantic. “Chet and the two girls haven't returned from their cave trip! They were due hours ago! Please help us find them!”
CHAPTER VII
Missing Spelunkers
FRANK tried to calm Chet's excited mother. “I'm sure there's nothing to be alarmed about, Mrs. Morton,” he said soothingly. “Joe and I will start looking right away. Did Chet tell you where he and Callie and Iola were going?”
“That's just itâhe didn't say exactly!” Mrs. Morton replied. “He did mention taking the West Road, but I don't know where. Oh dear, I never should have let them go!”
“Please don't worry,” Frank said. “We'll find them.”
As he hung up, Joe flashed him a questioning look. “What's wrong?”
“Chet and the girls are missing. Come on! We'll have to work fast before it gets too dark!”
The boys dashed out to their convertible and sped through the outskirts of town. Frank took the West Road. Outside Bayport, the road ran through a stretch of barren, rocky hillsides.
“Slow down,” Joe said as they came to a turnoff. “Let's check this road. There might be a cave around here.”
Frank braked the convertible and swung off onto the dirt shoulder. Joe leaped out, hoping to find the tire tracks of Chet's jalopy. He came back a moment later, shaking his head.
“No luck.”
Most of the area was uncultivated, with scraggy brush and timber growing up the hillsides. As the boys rode along they passed a rock quarry and several gravel pits. Here and there, dirt lanes branched off, leading to scattered farms or other roads.
The Hardys checked several of these rutted paths. On the fifth try, Joe shouted:
“Hey! This may be it!”
Frank hurried to join him. His brother pointed out a set of narrow tire tracks with a worn, old-fashioned tread pattern.
“Those are Chet's, all right!” Frank confirmed. “I noticed the treads that time we helped him change one of his tires.”
Hurrying back to their car, the boys turned up the lane. The convertible jounced and jolted so badly that Frank shifted into low gear.
Moments later, Joe gave a cry of relief. Chet's red jalopy was parked ahead. It had been pulled off the lane into a bordering clump of poplars. Beyond the trees, the ground rose steeply.
“There must be a cave entrance nearby,” said Frank. “We'd better take our flashlights.”
Joe grabbed them from the glove compartment and the brothers hopped out. Daylight was fading, but a clear trail of crushed undergrowth plainly showed which direction the spelunkers had taken.
The brush finally thinned out amid tumbled rocks and boulders. A few minutes' search, however, revealed an opening in the hillside.
