Pointer to Disaster
Scotty ran to the speedboat and yelled, "Come on!"
"Wait!" Rick called. "Let's not go barging off without knowing what
we're doing."
Scotty turned, puzzled. "What do you mean?"
"The girls have some kind of plan, and we don't know what it is. If we
go barging around in the speedboat, we might throw a monkey wrench
into the works."
"But we can't just stand here and do nothing," Scotty said
desperately.
"We won't. Go get the plane warmed up and wait for me."
Rick hurried into the house and ran up the stairs to Barby's room.
Working fast, he went through the dresser, then through the shelves in
her closet. Not finding what he wanted, he paused to look around in
case he might have overlooked a possibility.
He didn't know where girls kept things, and he suspected that
sometimes the places weren't the same as boys might pick. But he could
see no possible place that he hadn't searched.
That meant Barby had her Megabuck unit with her, unless she had left
it somewhere else in the house.
He plugged in his earphone and called. "Barby!"
There was no reply. His lips set grimly. No use wasting time here. He
ran from the house, hearing the sound of the Sky Wagon as Scotty
warmed it up. Joe Blake was not in sight. Rick hurried into the lab
and found him watching Professor Morrison who was checking some
calculations on the lab's small computing machine.
"Joe, step outside with me for a moment, please."
Outside, Rick explained that the girls were missing, then asked, "Can
you get the plane frequency on your receiver?"
"Sure. It's an all-wave job. What's the frequency you use?"
Rick told him, then explained, "We don't know what's going on, so we
want to be prepared. If some of your Scout leaders can move down the
coast to North Cove and keep an eye on the houseboat, Scotty and I
will search from the air. If we see anything, we'll let you know on
the plane's radio. You won't be able to talk back, but at least you
can hear us, and you can let the Scouts know."
He wished his mind had worked faster. Then he could have taken
Scotty's Megabuck unit and given it to Joe. But there was no time
now, and this other arrangement probably would do as well.
"I'll pass the word to the gang on the mainland right away," Joe
agreed.
Joe went back into the lab while Rick ran to Pirate's Beach. Scotty
was waiting, the plane's engine turning over. Together, they launched
the Sky Wagon, then climbed in, Scotty in the pilot's seat.
As Scotty took off, Rick tried Barby again on the radio. "Barby, this
is Rick. Can you read me?"
There was no reply.
"Better fly as though we were heading for Whiteside," Rick suggested.
He rubbed his palms on his handkerchief. They were damp with nervous
perspiration. He was not as calm as he looked.
Scotty swung around on course and Rick scanned the water as they
passed over the north side of Spindrift. There was no sign of the
rowboat yet.
The plane traveled in a straight line right across North Cove. The
houseboat was at anchor a few hundred yards offshore, and the pram was
tied up to the rear rail. There was no sign of life.
The boys reached the Whiteside pier without seeing the girls or the
boat. Scotty put the plane into a tight circle and looked at Rick
helplessly. "Now what?"
"They can't have gone far," Rick mused. "Not in the rowboat."
"They had the aqualungs," Scotty pointed out. "They must have expected
to use them."
"Right. But how? If they planned to get aboard the houseboat, they
wouldn't be using the aqualungs. Or would they?"
"Search me."
"Wouldn't they just row up to the houseboat on some excuse or other? I
wish I'd looked. Barby might have taken those clothes Dad wore home
last night."
"We can't just float around and talk," Scotty said urgently. "Let's do
something."
Rick felt the same way. "Okay. Throttle down and go slow. We'll scan
the whole coastline from here to Spindrift."
Scotty did so, holding the little plane barely above stalling speed.
Rick leaned out and traced the shore with anxious eyes.
The plane turned and twisted as Scotty followed the coastline as
accurately as he could. They reached the upper tip of North Cove and
swung into the cove itself.
Scotty tapped Rick on the shoulder and pointed. A man and a woman had
come out of the houseboat and were watching the plane.
"Wonder where the other pair is?" Rick asked. There was nothing they
could do about the people on the houseboat now. Let them wonder what
the plane was doing. Rick turned his attention back to the shore
below.
The plane traveled the length of the cove's shoreline and rounded the
southern tip. They passed over a section where the woods came right
down to the water. Birches leaned far over. Rick caught a glimpse of
what might have been the rowboat, then the plane swung and he lost it.
"Circle," he said quickly. "I think I saw something!"
Scotty gunned the Sky Wagon and threw it into a tight turn. Rick
watched carefully as the clump of birches came into view. There was a
boat under them, all right. He wished for the binoculars, but they
were probably at the attic lookout where Barby and Jan had spied on
the houseboat.
He had no real doubt. He was sure the boat was the Spindrift rowboat.
"Circle over the island," he called to Scotty, then reached over and
took the hand microphone from the instrument panel rack. He turned on
the radio and waited a moment while it warmed.
"Joe, this is Rick," he said. "Rowboat under a clump of birches just
south of North Cove. Have the boys go there and look it over. See if
the girls are in the woods. We'll watch for sign of the girls on the
water."
To Scotty, he directed, "Over the cove. Circle the whole area. We'll
watch for their bubbles. Joe's men will check the woods."
The plane turned obediently. Presently they were moving in a wide
circle with the houseboat as a center. A slight surface wind had
arisen and the water in the cove was a bit choppy, but not enough to
obscure bubble tracks made by Scuba divers below.
"See anything?" Rick asked.
"Not a trace. Can you see the water around the houseboat well enough?"
"Yes. No bubbles in the vicinity." Rick dried his palms again, then
mopped his forehead. He was becoming thoroughly frightened. Where were
they?
He checked his Megabuck radio to be sure it was on and called, "Barby.
Where are you?"
The air was silent, except for the slight background hiss that was
always present.
"Look right under the houseboat's gunwales," Scotty urged. "If they're
directly under it, the bubbles would rise along the sides."
"Why would they go under the houseboat?" Rick asked.
Scotty shook his head. "Why did they come over here in the first
place?"
Rick had no answer. "Let's go over to the shore. Joe's men ought to be
at the rowboat by now. Maybe they found the girls."
Scotty banked around and headed over the clump of birches. In a small
clearing behind the clump they saw two men in Scout uniforms. The men
looked up, and one spread his hands wide in a gesture that said
nothing of importance had been turned up.
"There's only one thing to do," Rick said decisively. "We've got to
check on the..."
He stopped as though a hand had clutched his throat. Barby's voice, in
his earphones!
Rick pulled the unit from his pocket and turned up the volume. He
couldn't hear her well.
"It's Barby," he said swiftly. "Circle!"
Rick strained to hear. She was talking to someone. "... It won't do
the slightest bit of good to keep us here, because my brother will
know where we are."
The signal faded as she talked. Rick turned the little radio unit,
trying to keep the volume constant.
"You'd better let us go," Barby was saying. "You'll get into a lot of
trouble if you don't."
Rick groaned. Her threats would do about as much good as a bunny
threatening a wolf pack. Where was she? On the houseboat?
Suddenly he realized ... he had the key in his hands!
Barby's voice was high-pitched and frightened now. "What are you
doing? Why are you putting that plastic cap on Jan?"
Rick turned the radio unit as the plane circled. The sweat stood out
on his face. Unerringly, the axis of the built-in antenna pointed to
the houseboat.
There was no longer any doubt!
"Land!" he yelled. "Land next to the houseboat!"
Scotty slammed the throttle in instant response, and as the Sky Wagon
dived toward the water he cast a quick look at Rick. "What did you
hear?"
Rick was already slipping off his shoes, getting ready to jump. "On
the houseboat!" he choked. "They're using the mind reader on the
girls!"
