<h2 id="c22">CHAPTER XXII <br/><span class="small">THE “GROUND CREW” TAKES HOLD</span></h2>
<p>“Hello, boys. Remember me?”</p>
<p>Dick rose to meet the man, tall, quiet, and
with a smile of greeting on his face that belied
the creases of worry around his eyes.</p>
<p>“I ought to,” Larry also advanced, rather
sheepishly. “I tackled you the day you floated
the dory out to the cracked-up seaplane.”</p>
<p>“Oh, no hard feelings, my friend,” the man
shook hands. “You wrenched a shoulder that
was already pretty painful—but you thought
you had a jewel robber to deal with, so let’s let
bygones sleep.”</p>
<p>He shook hands and accepted the lounging
chair Dick offered.</p>
<p>“I don’t believe I’ve introduced myself,” the
man began. “I’m Mr. Whiteside. Of course you
wonder what I am here for.”</p>
<p>Naturally they did. Each nodded.</p>
<div class="pagenum" id="Page_183">183</div>
<p>“I’ve kept pretty well in the background of
this case,” he told them. “I am, by profession,
an official of Mr. Everdail’s eastern enterprises.
But I consider myself something of an amateur
detective ‘on the side’ and I want you three to
help me.”</p>
<p>“But Mr. Everdail ‘discharged’ us.” There
was no resentment, only remonstrance, in
Larry’s quiet remark.</p>
<p>“Oh, I know it. I have seen him, been up in
Maine. But he has given me a free hand, and
I think you three can be useful. You see, I want
that hangar watched, now that the reporters
have gone away. I can’t be there day and night—I
know,” he broke off to explain, “that you
three have suspected me of having something
to do with the wrong side of the affair, and
naturally enough. I came upon Larry unawares,
at the seaplane. I accepted his offer about surrendering
jewels and actually had a gun in my
hand at the time. No wonder I fall in line as—well,
as a suspected person. I don’t hold that
against you. As it happens, I am trying to recover
the missing jewels, just because I made
such a failure of rescuing them before.”</p>
<p>That might, or might not be true, Sandy reflected;
but he maintained a careful guard over
expression and speech.</p>
<div class="pagenum" id="Page_184">184</div>
<p>“We aren’t doing anything about the mystery,”
stated Sandy, wondering if that might
be the plan—that this man had come to try to
pump news out of them. If so, Sandy was determined
that as long as they had given up, been
given up, it did not matter if the man knew it
or not.</p>
<p>“But you will do something! To help me out?”</p>
<p>“What?” Dick asked, with a mental reservation
as to any promise.</p>
<p>“Why, go out to the Everdail estate, under
my direction, and watch.”</p>
<p>“We’d be trespassers,” argued Sandy. “We
might be arrested.”</p>
<p>“I can arrange all that.”</p>
<p>Mr. Whiteside turned directly to Larry.</p>
<p>“I need you for something else,” he said.
“Atley Everdail isn’t here to help, if any situation
developed where I would need a pilot. I
have a theory that makes me think I shall need
one——”</p>
<p>“What about Tommy Larsen?”</p>
<p>The man who had piloted the cracked-up seaplane
was again able to fly, he responded, but
was not safe for a long flight. Besides, the detective
argued, he wanted someone who had
proved himself trustworthy in more things than
flying.</p>
<div class="pagenum" id="Page_185">185</div>
<p>“I’ve had only about nine hours instruction,”
Larry said honestly. “I wouldn’t like to risk
soloing on that. I can taxi, handle the ’plane
to get into the wind, take off and fly level, bank,
turn, circle, spiral, climb, shoot the field and
set down. But——”</p>
<p>“That is all settled in advance,” Mr. Whiteside
stated. “Tommy Larsen is ‘kicking around’
without a job. I’ve got his consent to finish your
instruction, and put you in trim for a license by
the end of Summer.”</p>
<p>Sandy, watching his friend’s face take on an
eager light, a look of longing, decided that Mr.
Whiteside could not have found a more certain
way to fascinate Larry and enlist his cooperation.</p>
<p>Dick, too, showed an interested face.</p>
<p>“That would be great!” Larry declared. Then
he became more serious, adding. “Finishing up
my course would be fine, but if it means that I’d
have to do anything against Mr. Everdail’s
wishes, after he told us——”</p>
<p>“He wishes to recover those emeralds, my
boy.”</p>
<p>“But he has agreed with Miss Serena that
they are destroyed,” Dick objected.</p>
<p>“And I think they are not destroyed!”</p>
<p>He gave them his theory.</p>
<div class="pagenum" id="Page_186">186</div>
<p>“When Everdail gave me all the facts he had
about the London attempt to ruin the emeralds,
the first idea I had was that some independent
robber had failed to find the real gems
and, in spite, had damaged the imitations.”</p>
<p>“But no other jewels were taken!”</p>
<p>That supported his decision that neither a
single robber nor a band of miscreants had
planned the affair. They would have taken all
the real stones, and he believed that these were
numerous.</p>
<p>“I weighed the situation,” went on the detective.
“A robber would be enough of a gem expert
to know the stones were imitations and
would have taken the others. But—some Hindu
fanatic, in India, where the emeralds came from
originally, might have a fixed idea that they
must be destroyed. He might not know imitations
from real ones.”</p>
<p>“That would explain why acid was put on
them,” agreed Dick. “It wouldn’t explain any
other attempts, though.”</p>
<p>“No! I argued that as soon as a Hindu accomplished
the entry to the hotel and believed
he had destroyed the stones, he would stop.”</p>
<p>“Then why did you and Mr. Everdail fly out
to meet the yacht?”</p>
<div class="pagenum" id="Page_187">187</div>
<p>“We wanted to take every precaution, Larry.
There was a chance that no Hindu was involved.
It might be someone with what the French call
an <i>idee fixee</i>—a fixed notion—a demented purpose
of destroying emeralds—no other stones
were treated with acid except those lying in the
little pool around the emeralds.”</p>
<p>“Are there people as crazy as that? And
going around, loose?”</p>
<p>“Once in awhile you hear of such people,
Dick.”</p>
<p>“Well, wouldn’t anybody in England give up
then?” asked Larry.</p>
<p>“Anybody who remained in England would
have to—he’d be left there. But—” Mr. Whiteside
leaned forward and spoke meaningly, “—a
man sailed from England—and although I did
not know it at the time, I have checked up, since,
and the man from London is an English circus
acrobat—who went in for ‘stunting’ on airplanes.”</p>
<p>“The man who claimed to be a secret agent of
a London insurance firm?” asked Dick, amazed.</p>
<p>“The firm sent no investigator!”</p>
<p>“Then we have found the man who is guilty!”
exclaimed Dick. “He was with Tommy Larsen,
hired him to go out to meet the yacht!”</p>
<p>“That seems to be the fact,” Mr. Whiteside
admitted. “Before the arrival of the yacht I
had no inkling that this fellow had come over;
but Mrs. Everdail was so nervous and worried,
we decided to fly out to meet the yacht, just as
Jeff, who had been retained before Everdail
found me, decided to do.”</p>
<div class="pagenum" id="Page_188">188</div>
<p>Sandy had made no contribution to the discussion.</p>
<p>He spoke, at last, quietly.</p>
<p>“I said, early in the adventure, that nothing
was what it seemed to be,” Sandy remarked.
“This backs me up. But——”</p>
<p>“But—what?”</p>
<p>“Look at this, Mr. Whiteside—we are sure
he made a try for the emeralds in the seaplane
he hired. He thought they were destroyed—at
least he had done all he could to destroy them.
Then—why did he make another try?”</p>
<p>“Maybe he wasn’t sure he’d done what he intended,”
argued Dick.</p>
<p>“He had ruined them! Wasn’t that enough?”</p>
<p>“My idea is that he learned—there was an
accomplice on the yacht——”</p>
<p>“Mimi?”</p>
<p>“Perhaps! He must have learned that the real
gems were not ruined at all,” Mr. Whiteside
explained.</p>
<p>“Do you think his confederate threw the real
ones overboard, in the life preserver, with the
ruined imitations tied to it?”</p>
<p>Turning to answer Larry, the detective hesitated.</p>
<div class="pagenum" id="Page_189">189</div>
<p>“That doesn’t check up,” he said. “The confederate—Mimi—knew
the imitations! She
wouldn’t throw them at all. If she knew the
real ones were hidden in that life belt she’d
have flung that. But we know that the imitations
went overside and were in the gum—as
Sandy cleverly discovered. So—that makes it
all muddled up again!”</p>
<p>“I don’t understand how the haunted hangar
comes in,” protested Larry.</p>
<p>“That’s what I want to discover. It does come
in—I’m sure of that! You, and Dick and Sandy,
can help, I believe. Two to watch the hangar,
taking turns, and with my aid whenever I can
manage it. You, Larry, to perfect your flying
technique and be ready if I need you.”</p>
<p>“It sounds good to me!” urged Larry, turning
to his chums.</p>
<p>“Well, I say, let’s reorganize,” Dick had a
twinkle in his eye. “You, Larry, will be the sole
member of the Sky Patrol—and Sandy and I
will be—er—the ‘ground crew’!”</p>
<p>“That’s a good description,” the detective
chuckled.</p>
<p>“All right,” agreed Sandy. “Dick, you and I
are the ground crew. As soon as you’re ready,
Mr. Whiteside, we’ll take hold!”</p>
