<h3>How Sings the Gay Sardine?</h3>
<p>Rick and Scotty held a hurried consultation, mouth to ear.</p>
<p>"We'll have to get him," Scotty whispered urgently. He held up his spear
gun. "I've only got one shot in this."</p>
<p>Rick's instinctive reaction was the same. They had to rescue Tony! But
they also had a job to do.</p>
<p>"Wait," he cautioned. "They probably don't know we're here. Tony
wouldn't give us away. If they find out, we'll lose the pictures, and we
may make it worse for Tony. Let's stay right here and watch."</p>
<p>Scotty subsided. They floated motionless, eyes on the boat, peering to
penetrate the mist. The rain had let up somewhat, but the air was far
from clear.</p>
<p>Rick would have given the treasure they sought to be able to hear what
was being said on the boat. The three frogmen were all facing Tony, and
the conversation seemed to be pretty animated. Then, as he watched, the
boat pulled up anchor. It moved north.</p>
<p>"They're taking him to their house," Scotty gasped.</p>
<p>The boys swam frantically for shore, recklessly crossing the reef
without regard to the danger of cutting themselves on the sharp coral.
They reached the beach and shed tanks and equipment under the palms,
then raced for the frogmen's house.</p>
<p>They could see the lights of the boat as it rounded the northern tip of
the island, and, lying among the palms, they watched it tie up at the
pier. Tony and the three frogmen got off and walked down the pier. Rick
strained to see, and could not find any sign that Tony was covered by a
gun. But that wouldn't be necessary, anyway, since he was outnumbered
three to one.</p>
<p>The four marched up to the front door of the frogmen's house and
stopped. The boys were prone under a palm less than twenty feet away.
One of the frogmen said, "Let me get a jacket. I'm getting chilled. Then
we'll walk you home."</p>
<p>There was something very odd here! Rick nudged Scotty and they backed
slowly away. When they were sure they could not be seen, they stood up
and ran on silent bare feet through the palm grove, circling to approach
their own cottage from the rear.</p>

<h3><i>Rick nudged Scotty to back away</i></h3>
<hr style="width: 65%;" />
<p>At the back door they paused. "Now what?" Rick said helplessly. "They're
bringing him home. Why?"</p>
<p>"I wondered about that while we were running. I think they're bringing
him home to check up on us. He must have sold them some kind of yarn."</p>
<p>"Steve's tail will recognize us!"</p>
<p>"Not if we're in bed," Scotty answered quickly. "We'll pretend to be
asleep. Come on."</p>
<p>"Just a minute." Rick hurried to the shed and got two short hand spears.
He handed one to Scotty. "Here. Have a bedfellow."</p>
<p>A few minutes later they heard footsteps and voices on the front porch.
The door opened. A strange voice said, "Your friends don't seem to be
here." The voice hardened. "I thought you said they were?"</p>
<p>"They're probably in bed," Tony replied mildly. "We go to bed right
after dark because there's nothing to do."</p>
<p>"Except stick your nose in other people's business," a harsh voice
snapped.</p>
<p>Tony replied tartly, "I've already apologized for letting my curiosity
get the better of me."</p>
<p>"I'd like to see the bedrooms," a third voice said. Rick thought it
belonged to the man they had taken off Steve's tail.</p>
<p>He lay motionless as a form blocked out the lamp-light from the living
room. In a moment the voice said, "They're asleep, all right. They must
sleep soundly."</p>
<p>"Young men do." Tony sounded relieved.</p>
<p>Rick grinned to himself. The archaeologist couldn't have known they were
in bed, but his stall had worked.</p>
<p>"All right. We'll be going. But keep in mind that the most stupid thing
anyone can do is to dive alone, even by day. At night it's worse than
stupid. It's sheer insanity. Also, we'll thank you and your party to
keep away from us and not gum up our recordings with your flipper noises
and bubble sounds."</p>
<p>"We will," Tony said. "Good night."</p>
<p>The front door closed. Scotty rose, slid open the window, and went out.
Tony scraped a chair in the living room. Rick stayed where he was, in
case the frogmen had lingered outside. In a few moments he heard the
back door open and close, and he tensed, but it was Scotty's voice that
spoke.</p>
<p>"They're gone. I just wanted to make sure."</p>
<p>The three gathered in the living room, and Tony chuckled. "If I
associate with you two for much longer, I'll get to be the world's
champion dissembler."</p>
<p>"What happened?" Rick demanded.</p>
<p>"Simple and unlucky. The two frogmen surfaced practically under me. My
own fault, because I had moved much closer to the boat. I think one of
them almost fired a spear at me, but the other stopped him. They invited
me to go aboard, and I didn't think it wise to refuse the invitation."</p>
<p>"I imagine not," Rick commented grimly. "Then what?"</p>
<p>"Naturally, they demanded to know what I was doing. I admitted to
overpowering curiosity that got the better of my manners. They wanted to
know who I was and why I was on the island. I told them the truth, of
course, at least partly. I identified all of us. Then I'm afraid I told
a slight untruth. I said we had found reference to the <i>Maiden Hand</i> in
an old manuscript, and were diving in hopes of finding cannon and other
old things which we planned to sell for museum pieces to pay for our
vacation. I believe they accepted my story."</p>
<p>"It's a good story," Scotty approved. "Just enough truth to make it ring
true."</p>
<p>"They've been watching us," Tony went on. "They asked why the plane had
gone, and why it had come back with only the pilot. I told them
Professor Zircon had cut himself and gotten a coral infection, and that
the doctor at Charlotte Amalie felt that he should stay there for
treatment."</p>
<p>"I guess they haven't recognized Scotty and me as the two who stopped
Steve's tail."</p>
<p>"Seems not," Tony agreed. "Well, I admitted that I was still curious
about their activities, since night diving is not common. So they told
me a story."</p>
<p>The boys waited breathlessly.</p>
<p>"These gentlemen thirst for scientific knowledge," Tony said with a
grin. "They claim an interest in ichthyology, but they know less about
fish than any cat does. Their story is that they have developed an
underwater recording device with which to make recordings of fish
noises. Since they have some evidence that certain fish make their
noises only at night, it is obviously necessary to make recordings at
night. So they dive, leave their equipment, and pick it up the next
morning. Our diving too close to their gadget creates false sounds,
especially our bubbles. Therefore we are requested politely but firmly
to stay away."</p>
<p>Scotty whistled.</p>
<p>Rick laughed. "Quite a story," he said.</p>
<p>"I pointed out the obvious," Tony went on, "that it was strange they
should choose a stormy night. Their answer was that storms upset fish,
and they thought it possible that some sounds might be obtained only
under storm conditions."</p>
<p>"Very interesting," Rick remarked. "It's a good story, and if we didn't
know Steve was after at least one of those men, we'd probably believe
it!"</p>
<p>"Fish noises!" Scotty exclaimed. "If they knew we'd been snooping around
before, they'd probably claim that the octopus really did wail, and that
they were only recording him. Your gag about screaming squid and
burbling barracuda would appeal to them, Tony."</p>
<p>The archaeologist chuckled. "Anyway, we got out of that one pretty well.
I had a little trouble banging my tank. Didn't want to do it overtly, of
course. Finally I managed to get in position while we were swimming to
the boat, and I banged my tank against one of theirs. But how did you
know what to do?"</p>
<p>Rick explained briefly, then he broke into a smile again. "These guys
are smart," he declared. "I like that fish-recording story."</p>
<p>"It's appealing," Tony admitted. "I'm almost tempted to pay them another
call tomorrow to ask if they have captured for posterity the hunting cry
of the wild sea trout, or the love song of the gay sardine."</p>
<p>"But you won't," Scotty said practically. "You certainly came out of
that mess with a whole skin, Tony."</p>
<p>Rick laughed. "He's adventure-prone. And lucky. How do you beat a
combination like that?"</p>
