Deep Fathom

He watched the numbers climb. Five hundred meters. Finally, he thumbed the switch, and twin spears of light shot forward, penetrating the gloom, illuminating the landscape below.

Jack pushed a pedal and tilted the sub on its side, surveying the terrain below him. It was as perfect as he had hoped, the seabed maze of deep canyons. The section of broken landscape beneath him led all the way to the crash site. The plan was for him to use the sheltering cover to mask his approach, similar to the way he had used the sunken ruins to sneak up on David’s cutter. However, this time he hoped the end result would improve. Before, he had come back empty-handed.

As the depth gauge approached the six hundred meter mark, Jack angled the sub into a wide canyon between two ridges. He slowed his speed, balancing out his ballast to neutral buoyancy.

Ready, he engaged the thrusters and began the long winding journey.

The walls to either side were covered with clams and mussels, anemones and deep-sea coral. Lobsters and crabs worked around the boulders, waving and clacking claws at the stranger in their midst. Other life fled from his lights: schools of silver-bellied fish darted in unison and vanished in a blink, bloodred octopi swept away in panicked clouds of murky ink, and winged black skates shuffled deeper into the silt.

Momentarily awed by the marine life around him, Jack continued gliding along the canyon. Over the next hour, using his sonar and compass, he navigated the maze as best he could, wending a zigzag path.

Circling around a seamount, he dove into a long narrow canyon. It was perfect. Side cha

He checked his watch. Four hours till noon. He was cutting it close. Gu

Caught from behind, the sub’s stern catapulted upward, flipping the Nautilus end over end and slamming it into the far cliff.

Jack gasped, his head cracking against the dome. The Nautilus scraped down the rockface, rolling. A sickening metallic scrunch sounded as something tore away from the sub’s undercarriage. One of the xenon lamps burst with an audible pop, casting shards of thick glass.

He fought to keep his seat, praying for the i

Working the foot pedals, he righted the sub. His visibility was zero as he hovered in a cloud of silt and sand. Through his hydrophones, a hollow tumble of rock sounded behind him. Looking over his shoulder, he could just make out a collapsed wall of boulders.

He craned his neck up. Beyond the top of the seamounts the silt cloud was clearing as swifter currents swept it away.

Overhead, he spotted his attacker.

Another sub circled like a shark. Cigar-shaped with stubby wings, it prowled along, hunting. He knew this vessel.

The Perseus—the Navy’s newest submersible, as deadly as she was sleek. The admiral had shown him the specs on the night of the sabotage. She was twice the vessel the Nautilus was: quicker, able to dive deeper, more maneuverable. But worst of all — she had teeth.

Jack spotted the dorsal fin of this titanium Great White.

A stacked array of minitorpedoes.

With a twitch, Jack flicked off the remaining lamp of his sub. Darkness collapsed over him. Through the murk above, a weak beam of light sought him out, circling and circling overhead.

The hungry predator hunted its trapped prey.

Charlie paced the small confines of his lab, mumbling to himself. “The idea could work….” He had run the calculations over and over again, and tested the crystal several more times.

Still, he remained unconvinced. Theory was one thing. Before he was ready to commit to his plan, he wanted to consult with Dr. Cortez at the sea base. But time was ru

Leaning back over the computer, he tapped a button, and a three-dimensional globe of the Earth appeared on the monitor. A hundred small X’s orbited the planet. They moved slowly in a complex ballet. Off to the left a radiating wavefront of tiny lines edged minutely toward the center of the screen, toward Earth. It marked the front edge of the solar storm blowing their way. Charlie checked the upper right-hand corner, where a little clock was counting down the time until collision with the upper atmosphere.

Four hours.

The dance of X’s around the globe were based on real-time data from the Marshall Space Flight Center, monitoring the incoming wavefront and extrapolating how it might affect the satellites in orbit.

Charlie placed his finger on one of the small X’s.

A knock on his door interrupted him. Lisa said, “Charlie, we have a call from Karen.”

Charlie straightened with relief. “Thank God! It’s about bloody time, mon!” He popped the disk of his latest data from the computer’s zip drive and dashed out the door.

He found Lisa and Miyuki gathered in front of the professor’s portable supercomputer. He immediately sensed the tension in the room. Neither woman looked happy.

“What’s wrong?” he asked Lisa, coming around the table.

On the screen, Karen had heard him and answered, “I was calling to see if you had heard from Dr. Cortez.”

Charlie bent in front of the camera. “What do you mean? Why not ask him yourself?”

“Because this morning I’d heard he’d gone topside during the night, and I’ve heard no word since. I had hoped he contacted you.”

“No. Not a word.” Charlie assimilated the information. “I don’t like this. With Dr. Cortez AWOL, maybe we’d better rethink things on our own. Just in case. Jack’s already left in the sub. I’ll patch you to the Nautilus so you two can coordinate on getting your ass out of there.”

Karen’s image flickered. “Maybe we’d better. The last scientists are due to leave in an hour, leaving me alone with David’s second-in-command. If there’s go

“Pray we do. Pray he’s been too damn busy making arrangements to save the world to bother updating us.” But even Charlie knew that such a prayer was unlikely to be answered. “Listen, Karen, I’ve been working on something, something we might try. Let’s all keep in close contact from here.”

“I’ll try, but it’ll be difficult. Lieutenant Rolfe is below assisting in the launch of the next sub. I feigned an urgent need to go to the bathroom to make this call.” She checked her watch. “And I’m ru

“Then let me patch you through to Jack.” Charlie turned to Miyuki.

The professor hit a button and spoke aloud. “Gabriel, can you patch this line to the Nautilus.”

A pause. “I am afraid I ca
