Shadows at Predator Reef Read online

  Joe rolled his eyes. “That’s great to know, bro, but it’s the Joe Hardy population I’m worried about.”

  “Even if we were diving with larger species, few shark attacks on humans are ever fatal,” I told him. “Most are just cases of mistaken identity, where the shark confuses the person for a seal or other natural prey animal. You don’t have much meat on your bones anyway, so even if one did accidentally take a bite out of you, they’d probably just spit you out like a bad brussels sprout.”

  “Well, that’s reassuring,” Joe huffed.

  I was disturbed too, but not because I was worried about a shark attack. There was another reason I had the shark-hunting problem on my mind as we geared up to dive into Predator Reef.

  Like Murph had said, sharks are an essential ingredient in a lot of traditional Chinese medicines.

  Just like with sea turtles.

  As we entered the calm water of Predator Reef, I hoped we would find something to prove that wasn’t the case with Captain Hook.

  Since Joe was taking scuba lessons and had a lot more experience than I did, I was going to let him go first and do most of the dive detecting in the deeper part of the exhibit tank, while I searched closer to the surface. We were going to use the aquarium’s special “dive comm” masks, which would allow us to communicate with each other underwater, so we could actually talk without having to rely only on hand signals.

  A rainbow of brightly colored fish scattered in front of him as Joe began his descent.

  “How’s it looking down there, Joe?” I asked. The dive comm masks made everything sound a bit bubbly, kind of like you might expect someone to sound underwater.

  “Totally sweet! It’s like exploring a whole different planet!” Joe’s enthusiasm was obvious even through the sound of all the bubbles. And there were lots of bubbles. They spewed upward toward the surface as he talked, making it a little difficult to clearly see Joe as he dived down.

  I swam through the shallows above Joe. I didn’t have the clear view he did because of the bubbles, but it really was beautiful. Actually being underwater in the fishes’ world was unlike anything I’d ever seen before.

  “I’m going to head for the nook where they found the broken coral,” Joe said, releasing another stream of air bubbles from the dive comm mask.

  “Right behind you,” I replied.

  A series of sleek, shark-shaped shadows passed over the bottom of the reef as the blacktips patrolled their domain. Man, was this cool! A moment later the cloud of fish vanished in a flash, taking cover in the coral. That was strange. The fish shouldn’t have been scared of us. It took me a second to realize it wasn’t us they were afraid of. Another shadow had appeared. It might have seemed cool too, if it wasn’t so terrifying. It was shaped like a shark as well, but this one was huge. Like, horror-movie huge. I wiped my mask, thinking maybe the condensation was making me see things. It wasn’t.

  Predator Reef had an uninvited visitor. One of the big sand tiger sharks had somehow gotten into the exhibit.

  It wasn’t just any sand tiger either. From the size of it, it could only be Bruce, the biggest shark in the whole aquarium. And Bruce did not look like a happy shark.

  Bruce wasn’t as large as a great white, but he was still big. Ten feet long and over four hundred pounds, with a mouthful of hideous needle-sharp daggers meant for spearing his prey, he looked like a swimming nightmare.

  I shook my head in disbelief. He shouldn’t have been in the reef tank with us. And whoever had let him out of Shark Row had him very riled up. He swam around Joe in big circles the way sharks sometimes do when they’re stalking prey. With each pass the circle would get smaller until the shark was within easy striking distance.

  Joe hadn’t seen him yet. But he had stopped swimming, and I could tell he sensed something was wrong.

  “Hey, bro, where’d all the fish go? Is something going on up there?” Joe asked. “It’s hard to see through all the bubbles.”

  “Shark!” I yelled. “We have to get out of the tank!”

  “Duh, there are about thirty of them. Stop messing with me,” he said.

  “I’m not messing with you, Joe!” I pleaded. “Get out of there now! One of the sand tigers got into the tank!”

  “Ha, ha, very funn—” Joe started to say. Then he saw Bruce. “Oh boy.”

  I saw a stream of bubbles spew from Joe’s mask and hit Bruce in his snout as he circled. Sharks have sensory organs in their noses that can pick up the tiniest electrical impulses in the water. To the shark, the unexpected burst of bubbles must have felt like an all-out assault!

  Bruce whipped around and charged into the bubbles, filling the space between Joe and me. I was still a few feet above Joe, and I swam hard for the surface as the giant shark passed close enough that I felt the water from his wake punch me in the legs. Then something clamped onto my arm from above.

  Oh no!

  But it wasn’t the shark; it was Big Chuck pulling me out of the water to safety. Luckily, I’d only been in a few feet of water, where he could reach me. Joe was still down there, though.

  My heart was pumping like a piston inside my chest and my head was throbbing from the quick ascent, but I couldn’t worry about that now. Not while my brother was still underwater with the shark.

  “Joe!” I yelled into the dive comm mask. “Take cover in the coral nook!”

  Joe didn’t respond.

  “Joe!” I yelled again, but there wasn’t any answer.

  I tried to dive back into the tank after him, but Big Chuck wrapped his beefy arms around me and wouldn’t let go.

  I looked down helplessly.

  The water was all cloudy with sand and bubbles. Deep below I could make out the form of the thrashing shark. There was no sign of Joe. Not until a second later. That’s when his scuba mask floated to the surface.

  JOE

  I GOTTA SAY, DIVING IN the reef was definitely one of the awesomest things I had ever experienced. Or at least it was until Bruce showed up.

  One second I was swimming through masses of amazing colorful fish and the next I was all alone. I was trying to figure out where all the fish went when someone dimmed the lights in the tank. That’s what it looked like at least. I thought Frank was playing with me when he said one of the sand tigers had gotten into the reef exhibit. It wasn’t until I started to make out the shape of the massive shadow passing over me that I realized what was going on. I had just turned into shark bait.

  Even with the bubbles clouding my vision, there was no mistaking the ferocious shark circling above me.

  “Oh boy,” I said, and actually laughed. It was an odd thing to do the moment before a shark tries to eat you, but I couldn’t help thinking about Aly jokingly calling me Aquaman. The laugh didn’t last long as it hit me that I might never get to see Aly again.

  Then the bubbles from my dive comm mask hit Bruce in his ugly snoot. He didn’t seem to like that one bit. The shark charged. I could just make out Frank above me, swimming frantically for the surface. I wanted to follow, but the shark was between us, cutting off my escape. I was trapped between an angry shark and the bottom of the tank.

  I swam for the closest coral formation, hoping to find somewhere to hide. The shark passed just over my head like a torpedo, its huge jaws chomping down on a mouthful of water. I heard Frank over the dive comm mask telling me to head for Captain Hook’s nook. Unfortunately, Bruce got there first. I found myself looking right into a grinning mouth chock-full of razor-sharp teeth.

  Bruce charged toward me. I felt like the little clown fish being chased around by the shark in Finding Nemo. It was a lot more fun to watch on the screen, I can tell you that!

  I swam for my life, diving behind an outcrop of coral on the floor of the exhibit just as the shark slammed into it, shattering the coral to bits. The shark’s tail whipped past my head as it swung around for another charge. There was nowhere left for me to go.

  That’s whe
n I noticed something strange on the floor of the tank under where the coral had been. It looked kind of like a trapdoor. With Bruce barreling straight at me, I didn’t have a lot of time to think about it. I reached for the small metal ring mounted on the door and pulled.

  The door swung open, creating a suction effect kind of like the drain plug being pulled on a big bathtub. I slipped through in a rush of water and slid the door closed behind me just as the shark’s jaws snapped shut on the place where my head had been.

  I was temporarily safe from the shark, but somehow my predicament had gone from bad to worse. My regulator had torn out of my mouth during my escape! No regulator meant no air. Don’t panic, dude. I tried to follow the emergency procedures Aly had taught me and did my best to hold my breath and stay calm until I could assess my situation.

  I was in a small airtight holding tank, just big enough for a diver.

  A diver and maybe a five-hundred-pound turtle.

  Had I just discovered how someone stole Captain Hook? If I was lucky, I’d get the chance to contemplate it later. Right then I had a more urgent mystery to solve—namely, how I was going to get out of the holding tank without drowning. I couldn’t hold my breath for much longer. I reached behind me for my Octopus—that’s the backup regulator attached to the scuba tank—but the hose was caught in the trapdoor. I couldn’t get it free without opening the hatch and exposing myself to Bruce.

  Just then I saw another latch, this one on the bottom of the tank. My lungs throbbed and my eyeballs felt like they were going to bulge out of my head. Out of options and nearly out of air, I grabbed the latch and yanked. The water trapped in the holding tank dumped out all at once as I fell through the air into total darkness.

  JOE HAD VANISHED. JUST LIKE Captain Hook.

  I struggled against Big Chuck, trying to get loose so I could dive back into the water after my brother. I broke free, but before I could leap into the tank, Chuck yanked away my regulator and tossed it aside. I wasn’t going anywhere without that no matter how much I wanted to.

  “I’m sorry, man,” Chuck said. “I can’t let you go down there. Not until we get the vets to tranquilize that shark.”

  I stared down, looking for some sign that Joe was okay. There wasn’t any blood in the water, and I could only hope that meant my brother had somehow managed to escape the shark’s bite without drowning. But where had he gone? Bruce looked as confused as I was. I could see him circling along the bottom of the tank, searching for his prey. When I reached down to pick up my brother’s scuba mask, I saw a face reflected in the water—one that wasn’t mine. I looked up. A hooded figure leaned over the rail one level above, watching me. As soon as the person realized I’d seen them, they bolted.

  Innocent people usually don’t run away.

  “Get help for my brother!” I called to Big Chuck as I took off after the suspect, kicking off my fins and dropping my air tank as I ran. Luckily, we had been wearing dive boots under our fins to protect our feet from the sharp coral. I never would have been able to give chase in bare feet.

  The figure ran down an escalator in the wrong direction, leaping the final few feet to the first floor and sprinting for the main exit. He or she was wearing a Bayport Aquarium hoodie, but I couldn’t see their face. My only hope was to catch them. The figure fled through the aquarium exit and I followed in close pursuit, chasing him or her along the pier toward the harbor.

  The suspect ran toward the boat rental place next to the water taxi station and leaped from the dock. For a second I thought they were going to dive into the bay, but they landed on the bow of one of the little motorboats tourists rent to tootle around the harbor. The kid running the rental booth yelled for them to stop, but the suspect already had the motor running and a second later was pulling away from the dock. Luckily, the little boats weren’t built for speed. There was a water taxi nearby, and I managed to hop aboard just before it shoved off.

  “Follow that boat!” I said to the elderly driver. He gave me a funny look, but he did as I asked. I don’t think he’d gotten that request before.

  The perp’s escape boat may not have been very fast, but neither was my water taxi. You know those high-speed car chases they show on the news? Well, this was the low-speed boat version.

  “Can’t you step on it?!” I asked the driver.

  “What do you think this is, a James Bond movie?” The driver laughed. “We’re in a water taxi pontoon, not a speedboat.”

  The driver was right, but the perp was getting away and there was no way we were going to catch up to them in the water taxi. The driver’s James Bond comment did give me an idea, though. When in doubt, ask yourself, What would 007 do?

  I saw my chance when the little motorboat veered back toward us to avoid hitting a terrified paddleboater. It was just close enough for me to try something drastic. I gave a running start and leaped from the water taxi with everything I had.

  And landed in the water with an unheroic splash a few feet short of the motorboat. The wake from the little boat smacked me in the face as the perp got away.

  The water taxi driver was in stitches when he circled back to pick me up.

  “Your fare is on me, son,” he said when he finally managed to stop laughing. “That’s the most entertainment I’ve had on the job in a long time.”

  I watched the hooded figure recede into the bay until the little boat disappeared around the bend of the harbor past the old industrial docks. Was it the same person who had stolen Captain Hook? Whoever they were, if they had intentionally released Bruce into Predator Reef while Joe and I were diving, then they were guilty of attempted murder. At least I hoped it was only attempted. I still didn’t know if Joe had managed to somehow make it out of the tank alive.

  He must have, right? That’s what I kept telling myself. If the big sand tiger shark had gotten him, there would have been blood in the water. I shuddered. He was probably hiding somewhere in the coral until it was safe to swim to the surface. He would have had plenty of air in his tank. Or maybe he made it to the surface in a different part of the reef where I couldn’t see him. Unless he’d gotten stuck somewhere in the coral out of Bruce’s reach . . .

  Stop it, Frank! Joe is going to be okay. He has to be.

  UNDER THE SEA

  JOE

  THOSE FEW SECONDS AFTER I pulled the latch on the second trapdoor were terrifying. I wasn’t airborne for long, but it felt like I was falling through the bottom of the world. I landed with a soggy thump a moment later. All I could see was total blackness. This must be what being blind feels like.

  I quickly checked for any scrapes, cuts, or broken bones. Nope, just sore from the fall. I tried to keep calm and use my other senses to get my bearings. I could hear the muffled burble of the four hundred thousand gallons of water in the reef tank somewhere above me, and I caught a noseful of an old musty smell. Like ancient journey-to-the-center-of-the-earth old.

  That’s kind of what it felt like too—like I’d fallen straight through the earth into a dark underworld. At least I was alive. The dark was really starting to creep me out, though. Had I escaped from the jaws of a killer shark only to face some new horror I couldn’t even see? I fumbled around until I found the dive light that was hooked to my wet suit and clicked it on. The little beam felt like a breath of fresh air for my eyes after being surrounded by all that inky nothingness. Yes! Let there be light! But where was I?

  Turns out I was in a really old tunnel. The floors and walls were packed dirt reinforced by wood beams. Or, to be more precise, rotting wood beams. There were old tracks running along the floor. I shone the light back up at the trapdoor. Beside it there was a small hydraulic lift similar to the one next to Predator Reef.

  Everything started to click into place.

  So that was how Captain Hook had vanished—through the trapdoor hidden under the coral on the bottom of the reef exhibit, into the secret h
olding tank, onto the hydraulic lift, and into the underground tunnel I found myself in now. The tunnel totally explained how someone could have entered Predator Reef and abducted Captain Hook without being caught on camera. A diver could have swum up from below and never even had to poke their head out of the water.

  I examined the holding tank with my flashlight. It was a brilliant piece of engineering. It was airtight, so water couldn’t enter or escape until one of the trapdoors was opened. When the top one was opened, the holding tank would fill with water from the exhibit so the diver could swim in with the turtle and then close the door, locking them safely inside, sealed off from the four hundred thousand gallons of water above. Opening the bottom trapdoor would then release the water contained in the holding tank, allowing the diver to lower the turtle with the hydraulic lift (so they wouldn’t go plummeting to the floor like I had) and presumably escape with the stolen reptilian booty. If they had some kind of cart or mobile turtle tank, they could then pull it, and the five-hundred-pound giant turtle, along the old tracks to freedom.

  So where was that five-hundred-pound turtle now?

  The tunnel looked like it had been there forever, but if I was right about the trapdoor and the hydraulic lift, somebody had very recently put a lot of thought and effort into transforming it into an escape route. Frank totally would have geeked out over the design of it all. I just needed to find a way out so I could tell him about it.

  I shone the light down the tunnel, which just disappeared into more darkness. I looked back up at the trapdoor. Even if I wanted to go back through the holding tank, there was still a giant angry shark up there waiting for me. Plus, I’d lost my regulator and Octo backup—and there was no way I was going to chance a free swim through shark-infested water without a breathing apparatus.
