LARRY'S CAPTURE
"How did you ever guess the gem was in the gum?" Dick stared admiringly
at Sandy, exultantly at the green light flashing from that hidden
emerald as Sandy scraped aside the clinging substance from it.
"First the gum was in the amphibian," Sandy said, trying to be as modest
as the discovery would let him, "then it was gone. We thought we saw
somebody in the hangar when first we went in--but he got away somehow.
Then we saw the amphibian flying and it flashed over me that whoever we
had seen before had been working on the amphibian and had chewed up all
those pieces of gum--but I didn't see why he had left it there. Then,
when we found out that the man calling himself 'Everdail' didn't look
for or miss the gum, I guessed that he hadn't been the gum chewer--but
who had, then, I wondered. And why. It must have been for some reason,
because if he had found the gum when he came to play ghost, keep
everybody away from the estate by scaring them, and get the amphibian
ready, he'd have throw any gum he found into the waste can."
"The gum was there for some reason," agreed Dick. "This is one time when
being suspicious has paid," he added.
"Yes," Sandy admitted. "When the life preserver was found and no gems
were in the oilskin tied to it, and Dick showed me the gum, the reason
for the big chunks of old gum came to me. The passenger had been getting
it ready. He had to chew a great lot to get enough."
"We mustn't waste any more time," cried Larry, eagerly. "There are
twenty-nine more chunks in the seaplane. Let's fly there, Jeff, and get
it."
"That-there is good sense." Jeff started toward the flying field. "The
fellow we didn't find might come back for the emeralds."
Going with them, to help out, Dick told Larry that he proposed to go at
once to the various airports and flying fields, to learn, if he could,
who had engaged the seaplane.
"The new Floyd Bennett field is the best chance," argued Jeff. "They
have got water and seaplane facilities there. It's on Barren Island, and
that's where a man could have gone, in about the time between your
seeing the 'spook' and the time the seaplane got where the yacht was."
"I'll wait for the yacht," Sandy said, accompanying them. "Mrs. Everdail
will be glad to see what I discovered."
That gave each of the members of the Sky Patrol something to do.
Dick had no difficulty in learning, when he got the executives of
Bennett field interested that the seaplane was an old one belonging to a
commercial flying firm operating from the airport.
"The pilot who handled the control job," the field manager told him,
"was a stunt man who has been hanging around since he stunted on our
opening day. I've questioned some of the pilots for you, but no one
seems to know who the pilot had with him. A stranger, one says."
That brought Dick's quest to a dead stop.
Sandy had even less success. Although in the short time since his
disappearance the supposed impersonator of Mr. Everdail could not have
gone far, he was not to be discovered by any search Sandy could make.
Farmhouses had no new "boarders." The house on the estate, searched with
youthful vim and alert thoroughness, revealed no observable hiding
places. Sandy finally gave up.
The arrival, anchoring and debarkation of its people by the yacht
allowed him to meet and to reassure Mrs. Everdail and Captain Parks.
Besides these two he met the almost hysterical French maid, Mimi, also
Mrs. Everdail's companion and cousin, who had traveled with her, a
quiet, competent nurse and attendant whose lack of funds compelled her
to serve as a sort of trained nurse for the millionaire's wife, who was
of a very nervous, sickly type.
In spite of everybody's relief when Sandy displayed the emerald, the
elderly trained nurse and companion insisted that Mrs. Everdail must
retire, rest and recover from her recent exciting experience.
Sandy, left alone, searched the hangar for an unseen exit, but found
none.
Landing the amphibian, at almost the same spot they had set down before,
Jeff looked around for the rubber boat they had left tied to a sunken
snag.
"I guess Sandy's ideas were right, after all," decided Larry as he saw
that the small water conveyance was not there. Sandy had claimed that if
the missing seaplane passenger had hidden during the recent search of
the seaplane, the boat would aid him to escape from the otherwise
water-and-swamp-bound place.
"If the rubber boat's gone," Jeff commented, "the twenty-nine other
emeralds of the thirty on the necklace--they're gone, too."
"I'll have to swim over again and see." Larry stripped and made the
short water journey.
"They're still here," he shouted across the channel.
Jeff, who had kept his engine idling, decided to risk a closer approach
in the amphibian whose lower wingspan barely cleared the tops of grass
clumps.
"I guess there aren't any snags to rip the pontoons," Larry assured him.
To get closer would save Larry many trips to and fro in the water.
"Fine!" Larry commented as the amphibian, moving cautiously, came close
enough for him to catch a rope and put a loop around the closest truss
of the submerged seaplane. Thus he was able to pass the chunks of gum to
Jeff, who had his clothes on and pockets for storage.
While the transfer was being made the amphibian's engine died with
unexpected suddenness.
"Golly-gracious!" Larry exclaimed, "I'll bet she's out of gas."
"Can't tell by the gauge." Ruefully Jeff upbraided his stupidity in
forgetting to see if they had to gas up before the take-off from the
estate.
"Now what's to do?" he wondered.
Larry, too, saw a number of difficulties--perhaps more than did Jeff,
because, from Larry's point of view, due to Sandy's suspicion of the
superstitious pilot, Jeff must not go free with the gems in his pockets,
nor did Larry dare be the one to go. If he did, Jeff might be playing a
trick, let him get beyond chance of return in time, use some reserve gas
and fly away.
"I can't swim," Jeff began, considering the ways of escape to some place
where they could secure a supply boat with fuel.
"I wouldn't chance swimming all the way down the swamps to the nearest
village on shore," Larry said quietly.
"This-here is a fix that is a fix," morosely Jeff summed up the
situation. "Here we are with a pocketful of emeralds--and no gas and no
way to get to any--and if anybody knows the gems are in this gum--we'd
be helpless if they wanted to take them."
Larry did not answer.
He was mentally going over the seemingly unbreakable deadlock.
One thing that kept coming into his mind was the strange fact that if
the disappearing passenger of the seaplane had taken the rubber boat he
had not also taken the hidden jewels.
"He must have known something about them--or guessed," he reflected. "If
they were put in the gum while they were flying--unless it was done
while they were in the fog. But, even then, he knew all that excitement
meant something. I don't understand it--he did know, because he must
have hired the pilot and the seaplane to get the emeralds."
Still, in that case, he mused, if the man had known where the gems were,
why hadn't he inflated the rubber boat and taken them all, in the first
escape?
A possible solution came to him.
Saying nothing to Jeff he bent his whole power of thinking on the more
important discovery of a way to get fuel.
Climbing onto the amphibian and dressing, he considered that matter
without arriving at any workable solution.
His eyes rested for a moment on the upthrust wing of the submerged
seaplane. His face changed expression. An idea flashed across his mind.
"Jeff," he cried, "do you suppose we could make a gas line from the
brass tubing on the seaplane?"
"What for?"
"See that wing?" he pointed. "It sticks up, and it's higher than our own
tank--and if there's a wing-tank, and I think a seaplane would have
them----"
"Why didn't I think of that?" grinned Jeff. "I wouldn't be surprised if
that-there is right."
He carefully climbed out onto the amphibian's lower wing till he could
grip a guy wire on the seaplane. By agility and a good deal of scuffling
with some damage to the doped fabric of the seaplane, he got into the
partly sunken pilot's seat and from that, climbing up, sent a quick
glance over the cockpit, tracing the fuel lines.
"Right as can be!" he called. "Now if I can find a wrench and get loose
some brass tubing----"
"Can I help?"
Jeff, bent down in the pilot's seat, lifted his head, shaking it.
"Stay where you are," he called. "Two might push the crate down into the
mud too fast for safety. She's half a foot deeper in than when we were
here before. I'll manage."
Shutting off the governing valve, Jeff began unscrewing the pipe lines,
rejoining lengths of piping until, with a section from the carburetor to
give the needed length, he passed over a makeshift path for the
wing-tank gas to flow by gravity into their own craft.
"All ready!" called Larry, bending the end of the line so its flow went
into the central tank of the amphibian.
Jeff opened the gas valve under the wing-tank.
"Here she comes!" Larry was exultant.
"We'll get enough to hop down the shore to a fuel supply, anyhow," Jeff
said.
The gauges were out of commission and they had to figure the amount they
secured from the size of the pipe and time that the gas flowed.
"I guess that's all--about seven gallons," said Jeff as the last drops
fell into their tank. Larry threw aside the useless pipe, sent home the
tank cap and dropped down into the after seat to be sure the ignition
was off before Jeff swung the propeller sturdily to suck the gas into
the cylinders.
So intent had they been on the business of the gas transfer that as Jeff
swung the "prop" both were taken by surprise when a curt voice came from
close under the amphibian's tail assembly.
"Put your hands up--both of you! Quick!"
A man, coming silently from some concealment, in a dory, undetected in
their busy absorption, held something menacingly businesslike and
sending sun glints from its blue steel. Its hollow nose covered both at
the range he had.
Up went Larry's hands. Jeff, also, elevated his own.
"Now!" remarked the stranger, pulling the dory around without losing his
advantage, "both turn your backs and clasp your hands behind you!"
"Wait!" said Larry, suddenly, earnestly. "I'll give you the jewels
without making any trouble--if you'll let me put my hand in my pocket
I'll throw the emeralds down to you."
The man stared, amazed, either incredulous or not quite understanding.
Larry had no emeralds and was well aware of it. Jeff still made his
pockets bulge with the packed chunks of gum.
But Larry had seen a chance that they might turn to their own advantage
if once the man's eyes could be diverted from Jeff. Just before he had
clambered onto the forward bracing to spin the amphibian's propeller,
Jeff had laid down the sturdy wrench he had used for bending the pipes;
evidently he meant to transfer it to his own tool kit but had wished to
start the amphibian's engine first.
The wrench, within his reach, could be used as a weapon. Larry had
caught Jeff's flash of the eyes toward it as his hands had been
elevated. From Jeff's expression Larry saw, out of the corner of his
eye, that the older pilot caught the younger comrade's purpose.
"All right," the man had recovered his surprised wits and was closely
watching Larry. "Which pocket?"
"This one!" Larry, carefully keeping fingers spread wide, tapped one
side of his coat.
"Throw the package or whatever it is----"
Jeff's hand was quietly coming down.
"It's stuck!" Larry began to tug, with his hand in his inside pocket
where he pretended the jewels were.
"No monkey shines!" warned the stranger, watching closely.
Jeff's hand flashed down, the wrench, with a twisting, underhand fling,
spun through the air. Jeff dropped into the cockpit. The wrench struck,
hitting the man's arm and deflecting the muzzle of his weapon as it
exploded--but he did not drop it.
In that split minute of time Larry was on the cockpit seat--and plunged,
in a swift, slantwise leap, down upon the man in the dory.
His unexpected assault was executed so rapidly that the man had not time
to recover from the surprise and get his weapon trained, before Larry
was on him, sending him sprawling backward.
"Oh--my shoulder!" the man cried out in sudden anguish.
Larry, startled, seeing the pain in the face just under his own, relaxed
for an instant, only being sure that his quick grip on the wrist holding
the weapon in its hand was not released.
"Oh!" the man groaned, and dropping his weapon, he began to nurse his
shoulder.
Larry suspected some trick, but there was none. The man tamely
surrendered. As he nursed his painful muscles, a sudden misgiving came
over Larry.
The man, he recalled, in pulling with his arm, had winced, before he got
the dory where he wanted it. His cry, his subsequent favoring of his
shoulder, told Larry the truth.
"You're the man who was in the amphibian when Mr. Everdail flew it!" he
said. "How did you get here, with your injured shoulder?"
"Tide brought me through a channel. I felt better, saw a spare dory and
watched some debris on the water and reckoned the tide would get me to
where I could see where the amphibian set down. I saw it hop off the
beach, saw it disappear, heard it and saw it coming back--and was
curious--but how did you know about Mr. Everdail--and who was in the
seaplane, and in the other crate I saw?"
"Here comes the tug and floating crane, to salvage the seaplane," said
Jeff. "You'll have to stay in the tug deckhouse, till we get the
straight of this--and for holding a gun on us. You can explain to the
police, maybe--as for us, we don't need to explain!"
And, as later, he and Larry resumed their places in the amphibian,
Larry's captive remained under guard on the tug.
