Morton stirred in slow anger. He did not like losing control of a situation on board his own command. “May I ask who these people are in Big John, as you call it, and how they came to be traipsing over the bottom of the Pacific Ocean?”
Sandecker gave a negligent wave of his hand. “Sorry, Commander, a classified project.” He turned his attention back to DeLuca. “You say they’re on the move.”
“Yes, sir.” DeLuca pressed a series of buttons and the display recessed in the table revealed a section of the sea bottom in a three-dimensional holograph. To the men crowded around the table, it felt as though they were looking down into a submerged Grand Canyon from the top of an aquarium. The detail was enhanced by advanced computer and sonar digital mapping that showed the images in muted color heavy on blues and greens.
The Mendocino fracture zone dwarfed the famous tourist sight of northern Arizona, its steep escarpments averaging 3,000 meters high. The uneven rims along the great crack in the earth’s submarine surface were serrated with hundreds of ridges, giving it the appearance of a huge gash through a series of sand ripples.
“The latest underwater visual technology,” Morton offered proudly. “The Tucsonwas the first sub to have it installed.”
“Code-named The Great Karnak,” Sandecker said loftily. “Knows all, sees all. Our NUMA engineers helped develop it.”
Morton’s face, now curiously red and sullen, looked abjectly defeated in the game of one-upmanship. But he took control and made a brave comeback. “Lieutenant, show the admiral his toy in action.”
DeLuca took a short wandlike probe and traced a light beam across the floor of the display. “Your underwater vehicle emerged at this point in a small canyon just off the main fracture zone and is now traveling in a zigzag pattern up the slopes toward the top of the fracture zone’s edge.”
Giordino stared somberly at the flattened area where the mining project once stood. “Not much left of Soggy Acres,” he said sadly.
“It wasn’t built to last forever,” Sandecker consoled him. “The results more than paid for the loss.”
Without being asked, DeLuca enlarged the display until the fuzzy image of the DSMV could just be seen struggling up the side of a steep slope. “This is as sharp as I can bring her in.”
“That’s just fine,” Sandecker complimented him.
Looking at the tiny speck against the infinite desolation, it was impossible for any of them to believe there were two living, breathing men inside it. The moving projection seemed so real, they had to fight to keep from reaching out and touching it.
Their thoughts varied to the extreme. DeLuca imagined he was an astronaut peering down at life on an alien planet, while Morton was reminded of watching a truck on a highway from an aircraft flying at thirty thousand feet. Sandecker and Giordino both visualized their friend struggling against a hostile atmosphere to stay alive.
“Can’t you rescue them with your submersible?” queried Morton.
Giordino clutched the rail around the display table until his knuckles went ivory. “We can rendezvous, but neither craft has an air lock to transfer them from one to the other under tons of water pressure. If they attempted to leave Big John at that depth, they’d be squashed to a third their size.”
“What about hoisting them to the surface with a cable?”
“I don’t know of a ship equipped to carry six kilometers of cable thick enough to support its own weight and that of the DSMV.”
“The Glomar Explorercould do it,” said Sandecker. “But she’s on an oil drilling job off Argentina. Impossible for her to cut off operations, re-equip, and get here inside of four weeks.”
Morton began to understand the urgency and the frustration. “I’m sorry there is nothing my crew and I can do.”
“Thank you, Commander.” Sandecker sighed heavily. “I appreciate that.”
They all stood silent for the next full minute, their eyes focused on the image of the miniature vehicle as it crept across the display like a bug climbing the side of a culvert.
“I wonder where he’s headed,” murmured DeLuca.
“What was that?” asked Sandecker as if he had suddenly awakened.
“Since I’ve been tracking him, he’s been traveling in a set direction. He’ll go into a series of switchbacks when the slope steepens, but after it flattens out again he always returns to his original course.”
Sandecker, staring at DeLuca, suddenly knew. “Dirk’s heading for high ground. Lord, I almost wrote him off without considering his intentions.”
“Plot an approximate course destination,” Morton ordered DeLuca.
DeLuca programmed his navigational computer with the data, then eyed the monitor, waiting for the compass projection. The numbers flashed almost instantly.
“Your man, Admiral, is on a course bearing three-three-four.”
“Three-three-four,” Morton repeated firmly. “Nothing ahead but dead ground.”
Giordino looked at DeLuca. “Please enlarge the sector ahead of the DSMV.”
DeLuca nodded and broadened the display area in the direction Giordino requested. “Looks pretty much the same except for a few seamounts.”
“Dirk is making for Conrow Guyot,” Giordino said flatly.
“Guyot?” asked DeLuca.
“A seamount with a smooth summit,” Sandecker explained. “A submarine volcanic mountain whose top was leveled by wave action as it slowly sank beneath the surface.”
“What’s the depth of the summit?” Giordino questioned DeLuca.
The young navigation officer pulled a chart from a cabinet under the table and spread it across the transparent top. “Conrow Guyot,” he read aloud. “Depth three hundred and ten meters.”
“How far from the DSMV?” This from Morton.
DeLuca checked the distance with a pair of dividers against a scale at the bottom of the chart. “Approximately ninety-six kilometers.”
“At eight kilometers per hour,” Giordino calculated, “then doubling the distance to allow for uneven terrain and detours around ravines, with luck they should reach the top of Conrow around this time tomorrow.”
Morton’s eyes turned skeptical. “Climbing the guyot may bring them closer to the surface, but they’ll still be three hundred meters or nearly a thousand feet short. How does this guy—?”
“His name is Dirk Pitt,” Giordino helped him.
“Okay, Pitt. How does he expect to make it topside—swim?”
“Not from that depth,” said Sandecker promptly. “Big John is pressurized to one atmosphere, the same as we’re standing in at sea level. The outside water pressure down there is thirty-three times heavier. Even if we could supply them with high-tech dive gear and a helium-oxygen gas mixture for deep-water breathing, their chances are nil.”
“If the sudden increase in pressure as they left Big John didn’t kill them,” Giordino added, “decompression sickness on the way to the surface would.”
“So what does Pitt have up his sleeve?” Morton persisted.
Giordino’s eyes seemed to peer at something beyond the r head. “I don’t have the answer, but I suspect we’d better t of one damn quick.”

THE STERILE GRAY expanse gave way to a forest of oddly sculptured vents protruding from the seafloor. They rose like distorted chimneys and spouted hot-365 Celsius-clouds of black steam that was quickly smothered by the cold ocean.
“Black smokers,” announced Plunkett, identifying them under the probing lights of Big John.
“They’ll be surrounded by communities of sea creatures,” Pitt said without removing his eyes from the navigational display on his control monitor. “We charted over a dozen of them during our mining surveys.”
“You’d better swing clear. I’d hate to see this brute run over them.”
Pitt smiled and took manual control, turning the DSMV to avoid the strange colony of exotic sea life that thrived without sunlight. It was like a lush oasis in the desert, covering nearly a square kilometer of seafloor. The wide tracks of the intruding monster skirted the spewing vents and the entwining thickets of giant tube worms that gently leaned with the current as though they were marsh reeds swaying under a breeze.
