It sounded as odd to him as it had seemed to Kurt. “Sixth sense going off?” he asked.

“Three alarms,” Kurt said.

“Funny thing,” Joe said, “I hear the same sound in my head right now. But I think it’s for a different reason.”

Kurt laughed. “All I want is a look,” he insisted. “Do you think the Barracuda can get us there?”

“There might be a way to do it,” Joe replied. “But only as an ROV. I wouldn’t trust the mods to keep anyone safe at that depth. Plus, there would be no room for us anyway.”

Kurt smiled. “What are you thinking?”

“We could build a small outer hull and encase the Barracuda inside it,” he began.

As Joe spoke he could see the design in his head, could feel the shape beneath his hands. He designed things intuitively. He did the math just to back up what he already knew.

“We fill that compartment with a noncompressing liquid, or hyperpressurize it with nitrogen gas. Then we flood the interior of the Barracuda itself or pressurize it to several atmospheres as well, and the three-stage gradient should help balance out the forces. Neither the outer hull nor the inner hull would have to handle all the pressure.”

“What about the instrumentation and the controls?” Kurt asked.

Joe shrugged. “Not a problem,” he said. “Everything we put inside is waterproofed and designed for a high-pressure environment.”

“Sounds good,” Kurt said.

He looked pleased. Joe knew he would be. And so he dropped the bomb.

“There is one minor problem.”

Kurt’s gaze narrowed. “What’s that?”

“Dirk called me before you got here.”

“And?”

“He gave me orders not to let you talk me into anything reckless.”

“Reckless?”

“He knows us too well,” Joe said, guessing it took one adventurous, even “reckless,” mind to know the workings of another.

Kurt nodded, smiling a bit. “That he does. On the other hand, ‘reckless’ gives us a lot of leeway.”

“Sometimes you scare me,” Joe said. “Just putting that on the record.”

“Draw up the plans,” Kurt said. “The race is in two days. After that, we’re on our own.”

Joe smiled, liking the challenge. And while he feared the wrath of Dirk Pitt if they lost NUMA’s million-dollar Barracuda, he was pretty certain that he and Kurt had built up enough markers to cover it if they did.

Besides, if the stories he’d been told were true, Dirk had lost a few of Admiral Sandecker’s more expensive toys over the years. How angry could he really get?

AS HE STRODE THROUGH THE PASSAGEWAY of the NUMA vessel Matador, Paul Trout had to duck each time he came to a bulkhead and its watertight door. While anyone over six feet had to crouch at the bulkheads or risk a nasty whack of the head, Paul was six-foot-eight in bare feet, with wide shoulders and long limbs. He all but had to contort himself to make it through unscathed.

An avid fisherman who preferred the outdoors, Paul was simply not designed for the tight quarters found inside a modern vessel. Naturally, he spent much of his time in one ship or another, twisting himself into small machinery-filled compartments, bending his spine like a pretzel to fit into submersibles, or even just walking the inner passageways of the ship.

On another day he would have detoured outside onto the main deck before walking the length of the ship, but the Matador was currently operating off the Falkland Islands in the South Atlantic. It was winter in the Southern Hemisphere, and both the wind and sea were up already.

Climbing through another hatch, Paul reached a more spacious compartment. He peered inside. The dimly lit room was quiet, with most of the light coming from glowing dials, backlit keyboards, and a trio of high-definition, flat-screen monitors.

A pair of scruffy-looking researchers sat in front of the outboard monitors, while in between them, on a plate of backlit glass marked with a grid, stood a shapely woman with hands outstretched as if she were balancing on a tightrope. A visor covered her eyes and held her wine red hair like a band, while strange-looking gauntlets with wires running from them encased her hands. On her feet a set of high-tech boots sprouted wires of their own, all of which ran to a large computer a few feet behind her.

Paul smiled to himself as he watched his wife, Gamay. She looked like a robotic ballerina. She moved her head to the right, and the picture on the monitors moved similarly, bright lights illuminating a smooth, sediment-covered surface with a jagged hole in what had once been the hull of a British naval vessel.

“Gentlemen,” she said, “there’s the entry point of the Exocet missile that sank your proud ship.”

“It doesn’t look all that bad, really,” one of the men said, his English accent as thick as his beard.

The Sheffield was the first major British casualty of the Falklands War, hit by a French-made missile that didn’t detonate but still ignited fires that raged throughout the ship.

She survived for six days after the attack before sinking during an attempt to tow her to port.

“Bloody French,” the other Englishman said. “Probably just getting back at us for Waterloo and Trafalgar.”

The bearded man laughed. “Actually, they went to great lengths to tell us the weaknesses of these missiles, and that helped us stop them, but I’d have preferred if they’d been a wee bit more cautious about who they sold them to in the first place.”

He pointed to the opening. “Can you take it inside?”

“Sure,” Gamay said.

She moved her right hand and closed her fingers on an invisible control knob. A second later the sediment stirred up a bit, and the camera began to move closer to the gaping wound on the ship’s hull.

Paul glanced at one of the displays on the wall. In a visual depiction reminiscent of a First Person Shooter video game, he saw what Gamay saw in her visor: a control panel and various gauges measuring depth, pressure, temperature, and both horizontal and vertical orientation.

He also saw a second screen that displayed a view from several feet behind the vessel she was piloting. Again it looked like a video game on the screen, as a small, almost human-shaped robotic figure moved forward toward the shattered hull plating.

“Detaching umbilical,” Gamay said.

Much smaller than a standard ROV, and shaped more like a person than an undersea vessel, the figure was known by the incredibly awkward name Robotic Advanced Person-shaped Underwater Zero-connection Explorer. Because the acronym shortened to RAPUNZE, the test team had taken to calling the little figure Rapunzel. And this moment, when it disconnected from all surface connectivity, was considered Rapunzel “letting down her hair.”

Under normal circumstances, Rapunzel could release the mile-long umbilical cord that kept her connected to the Matador and operate on her own in environments where cords, wires, and anything else trailing could be a hazard. Powered by batteries that would last three hours untethered, she was propelled by an impeller located in what would have been her belly. Fully gimballed, it could be rotated three hundred sixty degrees in any direction, allowing her to move up, down, sideways, backward, or any combination in between.

Because she was human shaped, she could bend and move into places a normal ROV could not go. She could even shrink, retracting her arms and legs so that she took up no more space than a beach ball with a light and video camera on top.

By using the virtual reality setup and force-feedback boots and gloves, the designers made it possible to operate Rapunzel as if a human were down there doing the work herself. It was expected this would be a huge boon to the salvage world, keeping divers out of dangerous wrecks and allowing exploration into wrecks long considered too dangerous or too deep to get at.
