Dirk Pitt 22 - Poseidon's Arrow

by Clive Cussler

  “Fighting the current has put an extra strain on the motors. I suggest we think about breaking off the run soon.”

  Summer checked their distance covered. “How about another six hundred meters? That will put us at an even twelve thousand.”

  “Deal.”

  Completing that last remaining stretch, Dirk pulled the submersible to a halt while Summer turned off the video cameras. He began purging the ballast tanks to ascend when Summer motioned out the front bubble window.

  “Is that a shipwreck?”

  Beyond the effective range of the exterior lights, Dirk saw a faint object. “Could be.” He released the ballast pump and thrust the submersible forward.

  A towering black mass gradually emerged, taking on the distinctive shape of a ship’s hull. As they drew closer, the rest of the vessel took form, sitting upright on the bottom and appearing remarkably undisturbed. Maneuvering just a few feet off the seafloor, they approached amidships, inching close to the mystery vessel. The red paint that covered the hull reflected clearly under the submersible’s lights, detailing every rivet and seam.

  “She looks like she just went under,” Dirk said. He drove the submersible up the side of the hull and above the deck rail. There, they spotted three large open hatches on the forward deck. Dirk piloted the submersible toward the bow, skimming over cargo compartments filled with nothing but seawater. They peered down the sharp prow, detecting no damage around the bow. They turned back and surveyed along the starboard rail to the rear superstructure, where they ascended several levels to the bridge. From just a few feet away, they peeked through the intact windows at an empty control station.

  “Looks like the helm was stripped of most of its electronics,” Dirk said. “That makes a good argument for her being scuttled.”

  “Somebody call Lloyd’s of London,” Summer said. “I’ve never seen such a pristine shipwreck. She must have sunk recently.”

  “No more than a few months, judging by the minimal sea growth.”

  “Why would somebody scuttle a perfectly good freighter?”

  “Hard to say. It’s possible she was under tow, headed for a refit, and sank in poor weather.” He checked the status of their battery power. “It’s about time we head topside, but let’s see if we can get a ship’s name.”

  He guided the submersible around the superstructure to the stern and descended past the aft rail. A bent flagpole hung forlornly over the rail, its former colors long since vanished. When they were twenty feet off the ship, he turned the craft to face the freighter’s transom and adjusted their height so the lights would shine on the ship’s name.

  “Well, I’ll be,” he said in a low voice. “She was scuttled after all.”

  In front of them stood a blank wall of red bisected by a thick horizontal band of rust where the ship’s name and home port had once been posted. But somebody had intentionally ground away the name and covering paint, sending the freighter to the lonely depths in total anonymity.

  THE NUMA RESEARCH SHIP ALEXANDRIA WAS stationed four miles away when the submersible broke the surface, and Summer radioed for recovery. As the submersible drifted with the current, she and Dirk passed the time studying the dusty brown shores of southern Madagascar, which seemed to rise and fall across the choppy sea.

  The Alexandria arrived promptly, its turquoise hull, like all the ships in the NUMA fleet, sparkling under a sunny sky. A brawny man with a thick mustache and even thicker Texas accent directed the retrieval of the submersible onto the ship’s aft deck. Jack Dahlgren opened the vessel’s rear-mounted hatch and welcomed Dirk and Summer to the fresh air. “Y’all have a good swim?”

  “We certainly did,” Summer said, holding up a portable hard drive. “We obtained excellent footage of the uplift and should be able to identify some prime insertion points for the ground sensors.” She climbed past him, scurrying to locate the ship’s marine geologist so they could jointly review the seabed footage.

  “I take it that means an immediate prep for another dive?” Dahlgren asked with a long face.

  Dirk patted him on the shoulder. “I’m afraid it does, my friend.”

  Dirk assisted Dahlgren in removing several heavy sets of battery packs that powered the submersible, swapping them with freshly charged replacements. While they worked on the aft deck, a large patrol boat appeared from shore. As the boat loosely circled the Alexandria, two casually dressed occupants on its open bridge studied the research ship with a look of displeasure. When the Alexandria moved off-site, the patrol boat ran back to shore.

  “I wonder what those boys are up to,” Dahlgren said.

  “They didn’t exactly look like government officials.” Dirk gazed toward the receding boat, and shoreline beyond. “I thought the coast around here was pretty well an empty desert.”

  “A small freighter came cruising through while you were down. It appeared headed to shore, so there must be some sort of harbor nearby.”

  They finished swapping batteries and completed an extensive predive safety check before tracking down Summer in one of the ship’s labs. She had assembled a crate of tiny battery-powered ground sensors that would track tremors and movements in the fault line. Each was contained in a stainless steel canister that sprouted a bright orange metal marker flag.

  “We’ve surveyed in a perfect location,” Summer said. “What we want to do next is go back and bury ten sensors, five hundred meters apart, along the same track.” She looked to Dahlgren. “Can you drop us back at the same starting point?”

  “Can a boll weevil find a Mississippi cotton field? You just go get yourself comfy in my submersible before I decide to put you over the side without it.” He stormed out of the lab, heading for the bridge to confer with the captain.

  “What’s he so touchy about?” Summer asked.

  “I made the mistake of telling him about the wreck we discovered,” Dirk said. “He’s mad that we found it in his submersible without him.”

  She shook her head. “Boys and their toys.” Summer grabbed the sensors and carried them to a cage basket affixed to the front of the submersible. Once they were secured, she climbed inside and joined Dirk in reviewing the predive checklist.

  Dahlgren appeared a few minutes later and ducked his head inside the hatch. “Good to go when y’all are.”

  “We’re launch ready,” Dirk said. “Have a couple of cold ones waiting when we get back.”

  “Sure, but they’re liable to be empty cold ones. Anything else?”

  “Yes. See what the records show in the way of southern Madagascar shipwrecks in the past five years.”

  “That I can do. Happy sowing.”

  Dahlgren sealed the hatch and hoisted the submersible over the Alexandria’s stern. He waited until a radio call from the bridge confirmed they were at the designated drop spot, then lowered the sub. Once the grapple was freed, Dirk was given the okay to flood the ballast tanks, and the yellow submersible slipped under the waves.

  The bottom appeared a few minutes later, and Dirk guided the submersible on its earlier northeast heading. This time they traveled less than fifty meters before crossing the familiar uplift.

  “Kudos to Jack,” Summer said. “He played the currents almost perfectly.”

  “Shall we drop the first sensor?” Dirk asked.

  Summer checked their position, calculated from a dead reckoning program initiated at deployment. “Actually, we should move about thirty meters east to pick up our first track.”

  Dirk made the adjustment. He eased the submersible to a flat section of seabed adjacent to the uplift and powered off the thrusters to settle the whirling clouds of sediment they had stirred up. Summer took over from there, activating a pair of articulated robotic arms. She clawed a vertical pit into the seafloor with one arm, then used the other to grasp a sensor from the basket. She wedged the sensor into the pit and covered up the main body of the sensor, leaving just the bright orange flag protruding from the seafloor.

 
“That went well,” Dirk said. He powered up the thrusters and shot down the rift at top speed.

  “You in a hurry to get someplace?” Summer asked.

  “I figured we might take another look at the wreck when we’re finished.”

  Summer smiled. She’d had the same idea and made sure a backup video hard drive was aboard for them to film the wreck.

  They proceeded along the fault, planting the remaining nine sensors along the seven-mile route. When the last sensor was secured, Dirk checked their position relative to the shipwreck. He maneuvered the submersible a short distance until the mass appeared before them. “Right where we left her.”

  “I’ll get some video this time,” Summer said, activating the forward cameras.

  Dirk ascended the submersible as they approached the hulk, heading immediately for the main deck. He crossed to the opposite rail, allowing Summer’s cameras to film the width of the ship’s beam and its open holds, which were missing their hatch covers. He was on a mission of identification, as he turned the submersible and its video cameras toward the high rear superstructure. Its design would offer another clue to the age of the ship and its builder.

  Creeping up the front face of the superstructure, he zoomed over the bridge and hovered near the funnel, which protruded from the aft side. Commercial ships often carried the company colors or logo there, but this one was painted black.

  “Funny there’s no smudge marks,” Summer said. “Looks like it was freshly painted.”

  “Another attempt to conceal her identity.”

  “Take us in a little.” Summer leaned forward, peering closely at the funnel’s surface.

  While Dirk drew them in, Summer activated one of the robotic arms and flexed it toward the funnel. Making contact, she dragged the claw across the surface, leaving a foot-long gouge.

  “Please don’t carve your initials,” Dirk said. “I don’t want a Lloyd’s agent knocking on my door at two in the morning.”

  “Just checking what’s underneath.”

  As the paint flakes swirled away with the current, they could clearly see an ocher line beneath the scratch.

  “The funnel was originally gold, or had a gold band,” she said.

  “That’s one more nugget.”

  They filmed the wreck for another thirty minutes, capturing its length, deck configuration, and any other details that could aid in its identification.

  “Batteries are approaching reserve power,” Summer said.

  “I think we’ve learned all we can,” Dirk said. “Besides, Jack won’t be too happy if we surface after dark.”

  He purged the ballast tanks, and they began a controlled ascent. Several minutes later, they broke the surface amid a choppy sea driven by a gusting westerly. The sun was already dipping beneath a bank of clouds on the horizon, stabbing the fading sky with bolts of pink and orange. As waves splashed over the submersible’s acrylic canopy, Dirk saw a nearby boat approaching. It was the same patrol boat he and Dahlgren had seen earlier.

  “Looks like someone was waiting for us.” The boat turned directly toward them while increasing speed. “Might be a good time to call the Alexandria to come fetch us.”

  “I think I spotted them on the horizon.” Summer strained her neck to peer over the rolling waves. “They still look to be a few miles off.”

  She reached for the transmission button on her radio, then froze. “Dirk, what are they doing?”

  Her brother was already tracking the patrol boat, which approached at an uncomfortably high speed. The steel-hulled vessel was less than a hundred feet away. It should have begun to slow or veer off, but it didn’t.

  “They mean to ram us!” Summer shouted.

  Dirk had the thrusters engaged, but with a top speed of only three knots the submersible couldn’t outrun a sea turtle. With no chance to elude the patrol boat, and insufficient time to dive, Dirk reacted the only way he could. He turned the submersible directly toward the oncoming vessel.

  Summer looked at him as if he were insane and braced for the collision. Dirk kept his eyes glued on the boat, maneuvering toward its sharp bow as if on a death wish. He waited until the craft was nearly upon them, then turned the joystick hard over while reversing the starboard thrusters.

  The submersible responded as if mired in quicksand, and Dirk feared he had reacted too late. But after a brief hesitation, it veered to starboard, narrowly slipping past the boat’s charging prow.

  As Dirk hoped, the patrol boat’s helmsman had locked on course and reacted too late to the last-second maneuver. Instead, the boat struck the submersible with only a light blow.

  Dirk and Summer heard a bang and felt their craft shudder as the contact crushed one of the rear thrusters. The impact briefly disrupted the power supply, shutting down the sub’s electrical systems. As Dirk frantically repowered the thrusters, he glanced out the spherical window as the patrol craft tore by. A man in green fatigues stood at the rail, pointing an assault rifle at the sub. But the gunman didn’t shoot, instead just offering a menacing grin.

  Summer fought off the urge to flash him an obscene gesture. “That was close.” She turned her attention to the radio. “Can you get us submerged?”

  “Trying.” Dirk had started flooding the ballast tanks even before the collision but had to reactivate the pumps after the power failed. They had only a matter of seconds before the patrol boat would swing around for another pass.

  “Still no power to the radio,” Summer said, resetting the breaker switches behind her seat. When that failed, she took a quick peek out the bubble. The ballast tanks had resumed filling, pulling the submersible almost beneath the waves.

  “She’s already turned. Nearly upon us,” she said matter-of-factly.

  She jumped back into her seat and cinched the lap belt tight.

  “C’mon, get down.” Dirk pressed the yoke all the way forward. With half their thrusters disabled, it did little to speed their descent.

  They could hear the patrol boat’s charging engines—and then the boat was upon them. The submersible had made it a few feet underwater, but the boat’s pilot had drawn a careful bead. Its sharp prow skimmed over the submersible, but its lower hull hit home.

  The crunching impact produced an explosion of bubbles as the acrylic bubble cracked and the ballast tanks were ripped free. The submersible bounced under the hull, battered in a series of punishing blows, until finally getting swept aside.

  The mangled shell wavered a moment before tumbling into a lazy death spiral that carried it all the way to the seafloor.

  THE SUBMERSIBLE MOANED LIKE AN ANGRY GHOUL as it plunged through the pressured depths. It struck the seabed with its nose, kicking up a thick cloud of brown sediment. The bottom current soon dispersed the plume, revealing the submersible’s hulk.

  Dirk felt like he had taken a ride in a washing machine. With its ballast tanks crushed, the submersible had flipped too many times to count as it sank. A monitor screen had torn loose during the tumble and struck Dirk in the head. He gently touched the top of his forehead and rubbed the length of a nifty gash. Other than the cut and some assorted bruises, he was unhurt—and thankful to be alive.

  The submersible’s rear frame had taken the brunt of the collision with the patrol boat, mangling the thrusters, battery compartment, and oxygen tanks. Despite numerous hairline cracks, the cockpit’s acrylic bubble had somehow survived intact, sparing the occupants a quick drowning. A dozen tiny leaks were filling the cabin with icy water, but the craft had survived the plunge still filled with air.

  “You okay?” Dirk asked across the dark interior. He reached for a penlight clipped to the console, but it had broken free.

  “Yeah,” Summer said in a shaky voice, “I think so.”

  Dirk released his harness and fell forward into a foot of cold water. The craft had landed on its face, creating an odd disorientation. Hissing erupted from several points around the submersible. Dirk couldn’t tell if it was water spraying in t
hrough tiny fissures or the remnants of one of the oxygen tanks. He climbed over the back of his seat and groped for a side storage panel where another light was kept.

  Wading through a cold, black, steadily flooding submersible would have led most people to panic, but Dirk felt an odd calmness. Some of his composure came from having trained for just such an emergency. But there was also a personal component.

  He had lost a woman he loved in a terrorist attack in Jerusalem the year before, and that had changed him. Since then, joy had become a harder attitude to embrace, and he had taken to viewing the world in a colder, more cynical manner. More than that, death had become a companion he no longer feared.

  “We’ll have to wait for the cabin to flood before we can pop the hatch,” he said matter-of-factly. “The pony bottles should get us to the surface.”

  He located the storage compartment and retrieved a small flashlight. He flicked on the beam and aimed it at his sister.

  One look at Summer’s face told him something was seriously wrong. Her eyes bulged in a look of pain and fear, and her lips were set in a grimace. She released her harness and tried to stand but could only hunch over at an awkward angle.

  Dirk aimed the beam toward her right leg, which was pinned against the seat. A small stain of blood marked her pant leg just above the ankle. “It’s no time to get attached to this place,” Dirk said.

  Summer tried to move, squeezing her eyes shut as she pulled at her leg, but it was no use. “My foot is pinned,” she said. “Tight.”

  Dirk crawled over for a better look. The collision had driven forward one of the oxygen tanks, which in turn had mashed the lower floorboard. A plate of reinforced steel had curled up, catching Summer’s ankle against the seat’s housing.

  Water had already risen past her calf when Dirk reached down to examine the buckled plate. “Can you pull forward?”

  She tried, and shook her head. “No good.”

  He maneuvered past her. “I’ll try to move the housing.”

  With his back braced against the acrylic bubble, he placed his feet against the housing and pressed with his legs. Because of the awkward angle, he could apply only a fraction of his full strength. The housing rocked slightly, but nowhere near enough to free Summer’s leg. Dirk tried a few other angles, attempting to rock the housing, but without success.
