<h2 id="c28">CHAPTER XXVIII <br/><span class="small">NIGHT IN THE HANGAR</span></h2>
<p>Never was a returning prodigal greeted with
more delight than was Sandy when, close to
dusk, with a parcel under his arm, he joined
Dick and Larry inside a little Summer house
in the Everdail estate grove.</p>
<p>“Where have you been?” demanded Larry.
“We hunted high and low! We thought something
had happened to you when we saw Jeff
fly his airplane away, came here and didn’t locate
you.”</p>
<p>“I didn’t mean to scare you. But I’ve been
awfully busy.”</p>
<p>“Doing what, Sandy?”</p>
<p>“Following farmer boys down hot, sunny furrows
while they picked vegetables for market,
Dick.”</p>
<p>“Following farmer boys? What in the world
for?”</p>
<p>“To ask them if their fathers would buy a
book on family crests and have their coat of
arms thrown in free.”</p>
<p>“Have you lost your head, Sandy?”</p>
<div class="pagenum" id="Page_229">229</div>
<p>The youngest Sky Patrol grinned, and shook
his head in question.</p>
<p>“No, Larry. It was an excuse to get them
talking. I got the book out of Mr. Everdail’s
library and used it to make them think I was a
subscription agent—so I could ask questions.”</p>
<p>“Ask—questions?”</p>
<p>Dick and Larry spoke together.</p>
<p>“About what?” demanded Larry, and Dick
nodded to show he wanted an answer also.</p>
<p>“Well—about who is related to who, and family
scandals, and who works for this one and
that one—just ‘gossip’.”</p>
<p>Dick caught the impish youth by his shoulders
and shook him.</p>
<p>“Stop that! Tell us where you’ve been and
what you did? We’ve worried ourselves sick,
nearly.”</p>
<p>“I have told you.”</p>
<p>Then he became really serious.</p>
<p>He had been all over that section of the farm-lands,
he asserted, to see if he could pick up
any information that would give him some connection
between either Mr. Whiteside or Jeff, or
the mysterious seaplane passenger—and Mimi
or the yacht stewardess.</p>
<div class="pagenum" id="Page_230">230</div>
<p>“If I knew that, I thought we could start
patching clues together,” he finished. “Because
Jeff has a lot to do with this mystery.”</p>
<p>“I think you’re right,” Dick agreed. “But
what started you off on that track?”</p>
<p>Taking an arm of each, Sandy led them, wordless,
up the path.</p>
<p>Spying carefully to be sure that Mr. Whiteside
was not in sight, and being certain that no
one else was watching, Sandy led his chums into
the hangar.</p>
<p>Across to one of its longer sides he led them.</p>
<p>“These are the switches that work the rolling
door motor, you remember?”</p>
<p>“Yes, Sandy. What?——”</p>
<p>“Look at them before it gets too dark, Dick.
Do you see anything strange? You know as
much about wiring circuits as I do. We both
built amateur short-wave sending and receiving
sets. You, too, Larry. What isn’t right
about the switches or—the wires?”</p>
<p>Thus guided, both studied the switches.</p>
<p>All Larry saw was that the wires were of a
braided form.</p>
<p>“But—are they?” He pulled a wire out a
trifle from the sheath.</p>
<p>Then his comrades observed what had first
attracted Sandy’s attention, puzzled him and led
to further search.</p>
<div class="pagenum" id="Page_231">231</div>
<p>One wire, somewhat lighter in its insulation
than the other, was wound around the heavier
one. They traced it, as Sandy had done. It
seemed to wind on down, as did others he
showed, from each switch-pole, into the protective
sheathing of metal and insulation; but none
really were wound any further. From there
on down, they ran behind the other wires!</p>
<p>“Bend down, close to the floor,” urged Sandy.
“See all the dust and lint piled up?” He scraped
some aside.</p>
<p>“My!” exclaimed Larry. “Golly-gracious-gosh-gravy-granny!
The wires come out from
behind the sheath and turn along the floor, close
to the wall—and there’s dust all covering them!
No wonder we didn’t notice them.”</p>
<p>“Where do they lead to?”</p>
<p>“Follow the dust line, Dick,” Sandy urged.</p>
<p>Back along the hangar wall they crept, until
they came up to the small wooden cupboard with
its dusty, frayed protecting burlap across the
front. Under the cupboard boards the wires
ran well concealed by more dusty lint which
seemed to have been swept into the corners by
the lazy act of some cleaner.</p>
<div class="pagenum" id="Page_232">232</div>
<p>“Inside here—but don’t use a light—inside
here, there are smaller duplicate switches for
the electric light arc and the motors,” Sandy
informed his breathless, admiring cronies.</p>
<p>They easily proved it. More, they located
the wiring in the dusk.</p>
<p>“But how does Jeff get in and out of here?”
asked Dick.</p>
<p>“We have to go outside so I can show you
what I discovered.”</p>
<p>Trooping around to the rear, at one corner,
Sandy bade them bend down and examine the
bolted metal sheaths, large plates of sheet iron,
that composed the walls of the edifice.</p>
<p>“I don’t see anything,” objected Dick, dejected
that he had not been as quick of wit as
had his younger chum. “But, then, you saw it
first by daylight.”</p>
<p>“I did, that’s so.” Sandy gave them all the
information he had. “I saw a break in the
paint, only up one-half of this big plate of iron.</p>
<p>“The bottom half pushed inward,” he explained.
“It has hinges fixed to the inner part
so it will lift up into the hangar and we can
creep in.”</p>
<p>He proved it, and they followed him through
the fairly low orifice.</p>
<div class="pagenum" id="Page_233">233</div>
<p>“Now,” he said, as Dick, last to crawl in,
cleared the edge of the metal, “see how clever
this is—the inside of the two plates it has to
come down against are fixed with something
soft—I think it’s felt—to keep the plate from
clanging. It fits so well that the only way I
found out about it was by the sun making the
dent in the paint show up a few little bright
worn spots of bare metal.”</p>
<p>They complimented him with no trace of envy.</p>
<p>“Do you think Jeff did this?”</p>
<p>“Well, Larry, he said he flew over here at
night. He chews gum and we saw how fast he
chewed the day he pretended to be forced to
land here. He knew all about the emeralds.
And the most telling thing against him is that
his wife—Mimi—is Mrs. Everdail’s maid and
was on the yacht——”</p>
<p>“Mimi his wife?”</p>
<p>Sandy nodded at Dick’s exclamation.</p>
<p>“Miss Serena saw her run in her uniform,”
contributed Larry.</p>
<p>“How did you discover she was Jeff’s wife?”</p>
<p>“Talking to farmer boys—what they didn’t
know, they found out from their older sisters
when any of them were picking up early potatoes
or snipping asparagus or digging up
onions.”</p>
<p>“My—golly—gosh—gracious——”</p>
<div class="pagenum" id="Page_234">234</div>
<p>Sandy agreed with Larry’s exclamations but
urged his chums to leave the hangar: they knew
all it could tell them. He wanted to replace the
book he had used and get away from the hangar
for awhile.</p>
<p>In the old, disused house, to which Mr. Whiteside
had secured a set of keys for them so they
need not hang around the grounds until there
was work to be done, they talked in low tones.
Sandy believed that Jeff had coaxed his wife to
put acid on the gems in the London hotel, as
had been done.</p>
<p>“He might be as much of a fanatic as that,”
admitted Larry, but not with any great delight—he
had always liked Jeff. “He is as superstitious
as a heathen.”</p>
<p>“But the maid knew those weren’t the real
gems!” Dick remarked.</p>
<p>“How do we know she did?”</p>
<p>“That’s so. But somebody said she did, or
thought she must know the real ones.”</p>
<p>“That doesn’t prove she did, Dick. The real
ones were hardly ever removed from safe deposit,”
Sandy argued.</p>
<p>“Then why did she throw over that life preserver?—”
and as he began the inquiry Larry
saw the answer.</p>
<p>“She—saw—the—captain hide—the real
gems!” he finished.</p>
<div class="pagenum" id="Page_235">235</div>
<p>“Jeff didn’t use the amphibian, though. And
he brought us here and induced us to aid him,
saying we were helping Mr. Everdail.”</p>
<p>“Yes,” Dick supplemented Larry’s new point.
“Another thing, Sandy, that doesn’t explain
why he’d take three boys and fly a ship he could
never use on water—with an amphibian right
here.”</p>
<p>“I am only saying what I believe. I don’t
know very much. But what I do know points to
Jeff.”</p>
<p>“But he didn’t get the life preserver.”</p>
<p>No, Sandy agreed, Jeff did not expect to do
that. He argued that Jeff must have planned
to superintend the affair, while the man in the
seaplane with Tommy Larsen secured the gems,
whereupon Jeff could chase him, probably turn
on him and get the emeralds, and then pretend
on his return that the man had gotten safely
away.</p>
<p>“But we don’t need to guess,” Sandy said.
“Before I began asking questions I met Jeff on
the way here.” He explained what made him
suspect the man who said he must repair his
“stalled” engine with a bolt that he knew was
not made—a slotted bolt. “I slipped down
across that estate to the inlet and saw the
amphibian. And Mr. Whiteside was in it, supervising
the filling of its tank!”</p>
<div class="pagenum" id="Page_236">236</div>
<p>“Then he means to get away with Jeff——”</p>
<p>“No he doesn’t!” said Larry, sharply. “Here
he comes onto the lawn!”</p>
<p>Pretending to be unaware of the arrival, the
Sky Patrol issued from the house.</p>
<p>They saw that Mr. Whiteside carried a life
preserver. In black on its side was painted
“<i>Tramp</i>, New York.”</p>
<p>“Well, Sky Patrol—and Ground Crew,” he
hailed them. “We are going to see some excitement
at last!”</p>
<p>“Why?” asked Larry.</p>
<p>“How?” Dick amended.</p>
<p>“We are going to trap the real culprit.”</p>
<p>“How?”</p>
<p>“By watching in and around the hangar to-night—and
this time our bait will be this life
preserver that I discovered in the swamp. I
guessed the ‘ghost’ was searching the amphibian
and the seaplane for the right life preserver.
I devised a plan to get rid of the caretaker
while Jeff and I made a complete, exhaustive
search, this noon. We found nothing; so
Jeff flew me over the swamp and we got—this.”</p>
<p>“Let’s open it!” urged Sandy, all his former
suspicions gone in his eagerness. “We can take
out the emeralds and then put the empty doughnut
in place.”</p>
<div class="pagenum" id="Page_237">237</div>
<p>“No. We won’t tamper with it. I want to
deliver it, intact, to Atley Everdail. His is the
right to open it.”</p>
<p>“Isn’t it a risk?” Sandy objected.</p>
<p>“No. Dick will watch inside the hangar,
Larry and I by the doors. Sandy will be in or
near the amphibian. If Jeff is the culprit we’ll
soon know—if he had a confederate we will discover
that, perhaps, also.”</p>
<p>“If it isn’t Jeff at all—and I hope it won’t
be,” Larry said, “if it turns out to be the seaplane
passenger who discovered that in his terror
he chute-jumped with the wrong belt, and he
comes to hunt the right one——”</p>
<p>“Or if it is Captain Parks, or his mate, or a
seaman—” Mr. Whiteside began to chuckle as
he led them toward the dark loom of the hangar,
“Or—even if it turns out to be—me!—”</p>
<p>“Did you walk under a ladder, today, sir?”
asked Sandy seriously.</p>
<p>“No. Why?” The man stared at him through
the night. “What makes you ask?”</p>
<p>“Because Jeff did—he walked under a ladder
where a man was pruning a tree as he came to
the gate of the estate next door.”</p>
<p>“Hm! Then—if he’s as superstitious as he
makes believe,” Larry laughed, “he’d better
watch out.”</p>
<div class="pagenum" id="Page_238">238</div>
<p>“He had that!” Sandy agreed.</p>
<p>And Dick, as they entered the hangar, rolled
down the doors, set the switch at neutral and he
was alone with Sandy in the pitchy blackness,
echoed the sentiment.</p>
<p>A new idea flashed into Sandy’s mind.</p>
<p>“Do you know,” he spoke through the darkness.
“Dick, we’re not watching that amphibian
at all! If Jeff did come here and managed
to get away, he’d go straight there and fly
off.”</p>
<p>Dick agreed, declared that with Larry and
Mr. Whiteside within call he dared to wait in
the hangar alone, and Sandy, going out through
the secret way, encountered Larry and the
detective, consulted them, had their sanction for
his idea and hurried off toward the next estate.</p>
<p>Thus divided up, the Sky Patrol spent dull
hours waiting.</p>
<p>But patience is always rewarded!</p>
