Poseidon's Arrow

45

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 through 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.

“I just can’t get enough leverage,” he said.

“It’s okay.” Summer spoke calmly, trying to mask her own fear and not place undue pressure on her brother. “Water’s rising. Better get the dive tanks.”

Dirk saw the water was already up to Summer’s waist. The leaks had increased, and the cabin was filling quicker. He dropped his legs into the water, which stabbed his skin with an icy bite, and climbed past the seats to the rear of the submersible. He reached for a rack next to the hatch that held emergency evacuation gear—two dive tanks fitted with regulators and masks.

He passed one tank down to Summer and looped the other over his shoulder. Then he rummaged around a compact toolbox, cursing that its wrenches and pliers were designed for small electrical repairs. The largest tool was a ball-peen hammer, which he grabbed, along with a short hacksaw blade. The blade summoned up the image of Aron Ralston, the courageous mountain biker who cut off his own arm after becoming trapped under a boulder near Moab. Amputating Summer’s foot with the hacksaw blade might become a gruesome last measure to save her life.

“Any ideas?” Summer asked when he climbed over with the tools.

“I’ll try and wedge the seat frame apart so you can slip out.” He passed her the light and hoped she didn’t notice the saw blade.

“Okay,” she replied, shivering as the cold water swirled around her chest.

Dirk slipped on his mask and regulator and ducked underwater. Jamming the hammer handle in the gap by Summer’s ankle, he could tell right away that it offered too little leverage. Still, he pressed himself horizontal and jammed his weight against the handle. The frame wavered but refused to bend or buckle. Further attempts yielded the same result. To force the heavy plates apart he needed more force, but there was nothing available. In frustration, he flipped the hammer around and banged on the frame, creating a tiny dent.

When he surfaced, he saw the water lapping at her chin. She had her mask on as she handed him the flashlight with a disappointed look. He turned the light toward the entry hatch. At any moment, it would become flooded. As he swung the light around, its beam played on an object beyond the exterior canopy. He felt Summer grip his arm, and she tilted her head out of the water to speak.

“Go on without me.”

There was no anger or panic in her voice, just resignation. She knew Dirk had tried everything. As twins, they shared a bond unknown by most siblings. They trusted each other implicitly. She knew if the situation dictated, he would readily give up his own life for hers. She was thankful that at least he would survive.

Dirk looked in her eyes and shook his head.

“Then cut it off,” she cried. “Now!” She had seen the hacksaw blade all along. Dirk could only admire her bravery, particularly as she pulled a bandanna from her jumpsuit pocket, twisted it into a tourniquet, and tied it around her lower calf.

Dirk had to wait for her to stick her head above water before replying. “I’m not ready to play Dr. Kildare just yet,” he said, forcing a grin. “Wait right here.”

Before she knew it, he had opened the hatch and swum out of the submersible, leaving her trapped and alone in the dark.
