<p style="margin-left: 5em;"><b>ENEMY FROGMEN</b></p>
<p>At the end of the test period, Bud had prepared to bring the jetmarine
to the surface. But just as he was about to blow the ballast tanks, Mel
Flagler sang out a warning from the sonarscope.</p>
<p>"Whoa! Hold it, skipper! I think we have company on the starboard beam!"</p>
<p>Bud jerked his head around in surprise. "You mean the <i>Sea Hound</i>?"</p>
<p>"No, she surfaced," Mel reported. "Can't make this out yet, but it could
be another sub."</p>
<p>Bud turned the controls over to Zimby Cox. Then he rushed to the scope
and examined the blip. "Seems to be moving away from us on a westerly
course. It's about two miles from here."</p>
<p>He donned the hydrophone earset and listened. "It's no seacopter, nor a
jetmarine either," he announced presently.</p>
<p>"A Navy sub, maybe?" suggested Zimby.</p>
<p>Bud shrugged. "Let's find out." He ordered a change of course, hard to
the right, and gunned the jets to bring the jetmarine directly on the
mystery object's trail.</p>
<p>"It's a sub, all right," he said a short time later, listening again
over the hydrophones.</p>
<p>"Pretty close to Fearing Island, isn't it?" put in Mel Flagler. "That's
a government-restricted area."</p>
<p>Bud nodded grimly. "But staying just out of sonar range from the base."</p>
<p>The jetmarine closed steadily on its quarry. In a few minutes they were
able to make it out dimly through the cabin window, dead ahead.</p>
<p>"That's sure no U.S. Navy sub that I know of," Bud said. "Probably an
enemy snooper."</p>
<p>"What if they spot us?" Zimby asked.</p>
<p>Bud chuckled. "That's the beauty of it, pal! Don't forget. With this new
antidetection gear we're invisible to them. At least as long as they
don't run into us or we into them," he added.</p>
<p>"Or unless they have superdetection equipment we don't know about,"
cautioned Mel Flagler.</p>
<p>As they talked, the unidentified submarine was bearing steadily toward
the mainland. Fathometer soundings showed it was on a steep upward slope
of the continental shelf.</p>
<p>Presently a foaming gush of bubbles showed that the sub ahead was
blowing its tanks. The jetmarine followed as it surfaced and Bud hastily
manned the periscope.</p>
<p>"What're they up to?" Mel asked tensely.</p>
<p>"Don't know yet, but the hatch is opening," Bud reported. Suddenly he
gave an excited gasp. "Jumpin' jets! They're sending out a couple of
frogmen!"</p>
<p>Bud's companions were electrified by the news.</p>
<p>"Spies!" Zimby exclaimed.</p>
<p>"What do we do now?" piped up Mack Avery, the third man in Bud's crew.
"Hadn't we better radio the Coast Guard and the FBI?"</p>
<p>Bud wrenched away from the eyepiece. "I have another idea! Any of you
fellows game to go with me and capture those spies?"</p>
<p>All three of his companions volunteered eagerly. Bud chose Mel Flagler,
then took another sight through the periscope.</p>
<p>"The sub's submerging again," he reported. "That'll give us a clear
field. Zimby, you and Mack keep an eye on that baby while we're gone,
and be plenty careful she doesn't spot you!"</p>
<p>"Roger! And take this roll of wire to tie up your prisoners."</p>
<p>Hastily Bud and Mel changed into swimming trunks and donned hydrolungs.
They went out through the air lock, plunged into the bracing salt water,
and switched on their ion-drive units.</p>
<p>"Can you see 'em?" Mel asked over his mike.</p>
<p>"Not yet. Let's speed up before we lose 'em completely!"</p>
<p>Both pushed their ion drives to capacity, scanning the water ahead in
all directions.</p>
<p>"There they are!" Bud exclaimed presently. He pointed to two tiny
figures, barely visible in the distance.</p>
<p>"Wow! They're sure not wasting any time!" Mel muttered. "Let's step on
it, Bud! They'll be ashore in a minute!"</p>
<p>A darting school of sea bass screened the figures briefly from view. As
the fish flickered past, Mel and Bud saw the frogmen breast-stroke up
toward the surface and break water.</p>
<p>Bud and Mel followed. Ahead lay a barren stretch of beach, humped with
sand dunes. It was skirted beyond by a thick fringe of trees.</p>
<p>"They certainly picked a perfect spot for a sneak landing!" Bud thought.
The beach seemed totally deserted, with no sign of human habitation.</p>
<p>By this time, the frogmen were scrambling ashore. Within moments, Bud
and Mel were on their heels. The raiders whirled in dismay as they
caught the sound of footsteps rushing up behind them through the sand.</p>
<p>Bud and Mel hurled themselves forward, each dropping a man with a flying
tackle. All four went down in a struggling, kicking tangle of arms and
legs.</p>
<p>The battle was rough but short. Bud and Mel had the advantage of
surprise, and soon pommeled and grappled their foes into submission.</p>
<p>Bud, astride his opponent's chest with knees pinning the man's arms,
unlooped from his belt the wire he had brought.</p>
<p>"Here! Take some of this and wire your man's wrists together!" Bud told
Mel.</p>
<p>When the frogmen were safely bound, Bud and Mel allowed them to stand
up. Neither captive tried to escape.</p>
<p>"Now, my sneaky friends, talk!" Bud snapped. "What kind of a sightseeing
trip did you plan?"</p>
<p>The frogmen's jaws remained tightly clamped. Both looked flushed and
sullen as they faced their captors.</p>
<p>"Got their lips zipped, I guess," Mel said disgustedly.</p>
<p>Bud decided to try another tack. "Doesn't matter," he said carelessly.
"We know they're pals of the Mirovs."</p>
<p>Both men started as if they had been stung. Bud followed up quickly,
hoping to prod them into some unguarded remark.</p>
<p>"Just as we thought!" he snarled. "A couple of low-down Brungarian
rebels! And up to their usual amateurish spy stunts!"</p>
<p>The raiders' eyes blazed, but they maintained silence. Both, however,
kept darting looks of keen interest at the Americans' hydrolung gear.</p>
<p>Just as Bud was wondering how he could get the prisoners to the nearest
police headquarters, a jeep came bouncing into view across the sand.</p>
<p>"Hey! Police!" Mel exclaimed with a happy grin.</p>
<p>"We're in luck," Bud said. "They can take these creeps off our hands."</p>
<p>The jeep braked to a halt a few yards away, and two uniformed officers
hopped out.</p>
<p>"What's going on here?" said one, who was wearing a sergeant's stripes.
The jeep had the words BEACH PATROL stenciled on it in white paint.</p>
<p>"We just nailed these two Brungarian frogmen," Bud explained. "A sub put
them ashore—probably as spies or saboteurs. They won't talk to us, but
maybe you can pump them at headquarters."</p>
<p>The startled sergeant turned a cold eye on the two prisoners. "Got
anything to say for yourselves?" When neither answered, he unholstered
his revolver and covered them. "Better take off those wires and put
bracelets on them, Mike," he told his fellow officer.</p>
<p>The frogmen were handcuffed with cool efficiency and bundled into the
jeep. Meanwhile, the sergeant turned back to Bud and Mel.</p>
<p>"You fellows come along too," he ordered.</p>
<p>"But we haven't got time," Bud protested. "Our own sub's waiting right
offshore and we want to tail the sub that brought those guys here!
We're from the Swift rocket base."</p>
<p>"Any identification?" the sergeant asked.</p>
<p>"How <i>could</i> we have in this getup?" Mel retorted.</p>
<p>"That's what I thought. So get moving," the sergeant barked.</p>
<p>Reluctantly, Bud and Mel hopped onto the running board and clung to the
bouncing jeep as it sped to the nearby town of Sandbank. At headquarters
they were questioned by the local police chief.</p>
<p>"If you'll call Swift Enterprises at Shopton, sir, Mr. Swift—or Harlan
Ames of the plant security department—will vouch for us," Bud said.</p>
<p>The chief picked up the telephone and soon had Mr. Swift on the line.
After speaking to him briefly, he passed the phone to Bud so the
scientist could identify his voice.</p>
<p>"That's Bud Barclay, all right. He's one of our most trusted employees,"
Mr. Swift told the chief after hearing Bud's story.</p>
<p>The officer promised to release Mel and Bud at once. Before doing so,
however, he took them into the adjoining office where the two frogmen
were being questioned.</p>
<p>"Any luck?" the chief asked the sergeant.</p>
<p>Sergeant Gryce shook his head in disgust. "Not much. They did admit they
came in a sub, but they claim it didn't wait to pick them up."</p>
<p>The police chief shot a few questions of his own at the men, but they
answered either in curt monosyllables or not at all.</p>
<p>"Look, sir," Bud put in, "if they're telling the truth about their sub
not waiting, our jetmarine may have chased it. That means Mel and I are
stranded here. Could you have your men wait for us on the beach till we
find out?"</p>
<p>"Gladly," the chief replied. "You two have done a fine day's work."</p>
<p>After the prisoners had been locked up to be handed over to the FBI, the
two Beach Patrol officers drove Bud and Mel back to the area where they
had landed. Just as the jeep turned down the dirt road leading to the
shore, Bud's keen eyes spotted a lurking figure in the distance.</p>
<p>"Stop, please!" Bud said, tapping the driver on the shoulder.</p>
<p>As the jeep halted, Bud pointed toward the beach. A man was crouching
behind a sand dune, with a large fish basket beside him. The sergeant,
puzzled, took out a pair of binoculars to study the situation.
Fortunately, the jeep was still screened by trees, and the crouching man
evidently did not realize he had been seen.</p>
<p>"What's in the basket?" Bud asked. "Could it be clothes?"</p>
<p>"Sure looks like it," the sergeant said, passing over the binoculars.</p>
<p>After a brief look, Bud explained the hunch that had occurred to him.
"I'll bet that guy's waiting with clothes for the frogmen. He probably
got here late and doesn't realize they've been nabbed!"</p>
<p>"Well, he'll soon find out," the police driver said grimly. He was about
to start up the jeep when Bud stopped him again.</p>
<p>"Wait! You have no proof that's what he's here for," Bud pointed out.</p>
<p>The pilot suggested that the police keep out of sight while he and Mel
approached the man in their swimming gear. "If that stranger takes the
bait, we'll really have the goods on him!" Bud concluded.</p>
<p>"Smart idea, son," the sergeant said with a dry chuckle. "Go to it!"</p>
<p>Bud and Mel circled widely through the trees, took a quick dip in the
water, then approached along the beach as if they had just landed and
were searching for someone.</p>
<p>To their delight, the man rose from behind the sand dune and hailed
them. Bud and Mel hurried over to him.</p>
<p>"You have clothes for us?" Bud asked. "We just came ashore from the
sub!"</p>
<p>"Yeah, right here," the man said in English with no trace of an accent.
"Thought I'd missed you."</p>
<p>"Thanks, pal—that's all we want to know!"</p>
<p>The man gaped in comic dismay as Bud pounced on him and pinned him to
the ground. Moments later, the two police officers rushed up and
handcuffed him.</p>
<p class="center">
<ANTIMG src="images/illus009.jpg" alt="man" /></p>
<p>"Hey! What's the big idea?" the man stammered. "I ain't done nothing.
Just got a phone call this morning, offering me fifty bucks to bring two
sets of clothes down to the beach at five o'clock for a couple of
divers."</p>
<p>"Tell that to the FBI!" snapped the sergeant.</p>
<p>When the officers had departed with their new prisoner, Bud and Mel,
both grinning, dived into the surf and headed out to sea.</p>
<p>In a few minutes they were sure they were at the right spot to meet the
jetmarine. But it was gone!</p>
