He nodded. “All right . . .” He seemed to be thinking. Then he turned and smiled to Kate. “I respect your judgment. I’m going to trust you on this one.” He turned to Ford. “I know you’re an honorable man. Welcome to the group—for real, this time. You’re now privy to our little secret.” His blue eyes were disconcertingly penetrating.
Ford tried to stop the flush from mounting into his face. He glanced at Kate and was startled by her expression—of what, hope? Anticipation? She didn’t seem angry that he’d pushed the issue.
“We will speak of this later, Wyman.” Hazelius let the hand slide off Ford’s shoulder and he turned to Wardlaw. “Tony, it looks like Mr. Ford will be part of the next run after all.”
The SIO didn’t answer. His face remained utterly stolid and expressionless, his eyes straight ahead.
“Tony?”
“Yes, sir,” came the strained answer. “I understand, sir.”
Ford made a point of looking at Wardlaw as he passed by. The man returned the look with cold, empty eyes.

KEN DOLBY WATCHED THE GREAT TITANIUM door to the Bunker drop down and seal itself with a hollow boom. A damp movement of air played over his face, smelling of caverns, wet stones, warm electronics, machine oil, and coal dust. He inhaled. It was a heady smell, a rich smell—the smell of Isabella.
The scientists filed past on their way to the Bridge. Dolby caught Hazelius as he passed.
“There’s a red light on Magnet 140,” he said. “I got a squelch warning on it. Nothing serious. I’m going to check it out.”
“How long do you think it’ll take?” Hazelius asked.
“Less than an hour.”
Hazelius gave him an affectionate pat on the back. “You do that, Ken, and report back. I won’t turn on Isabella until we hear from you.”
Dolby nodded. He stood in the vast cavern while the others disappeared into the Bridge. The door closed with a clang that reverberated through the hangarlike space.
Silence gradually returned. Dolby breathed once again the fragrant air. He had led the design team for Isabella—directing a dozen Ph.D. engineers and almost a hundred contractor-designers who were blueprinting specific subsystems and the supercomputer. Despite the many people involved, he had been firmly in charge, his hand in everything. He knew every square inch of Isabella, every quirk and foible, every curve and hollow. Isabella was his creation—his machine.
The oval opening to Isabella’s tunnel—like a slice taken off the side of doughnut—glowed in soft blue light. Condensation snaked out of the portal in sinuous tracks that crawled this way and that before evaporating. Inside the tunnel, just beyond the opening, Dolby could see the massive blue-gray wall of depleted uranium shielding— behind which was CZero, the beating heart of Isabella.
CZero. Coordinate Zero. This was the tiny place, no bigger than a pin-head, where the beams of matter and antimatter were brought together at the speed of light to annihilate themselves in a burst of pure energy. When Isabella was running at 100 percent full power, it was the hottest, brightest place in the entire universe—one trillion degrees. Unless, thought Dolby with a smile, there was an intelligent race of beings out there with a particle accelerator bigger than his.
He was inclined to think not.
Most of the energy of the matter–antimatter explosion at CZero was instantly converted back to mass, according to Einstein’s famous formula, E = mc2, and became an awesome spray of exotic subatomic particles, some not seen since the very creation of the universe in the Big Bang, 13.7 billion years ago.
He closed his eyes and imagined himself as one of the protons circulating in the ring, going round and round, being accelerated by the supermagnets to 99.999 percent the speed of light. He made the forty-seven-mile circuit four thousand times per second, round and round. He saw himself plunging down the curving tunnel at unimaginable speed, getting a kick in speed from each magnet, more than three million kicks per second, faster and faster . . . it thrilled him to imagine it. And ripping along just half an inch from him in the pipe was the beam of antiprotons, circulating in the opposite direction, whipping by him at the same incredible speed.
He imagined the moment of contact. His beam was forced into the oncoming beam. Into a head-on collision at CZero. Matter striking antimatter at the speed of light. Riding the particle into CZero, he felt the collision—the pure, absolute, thrilling annihilation of it. He felt his rebirth into strange new particles spraying outward in all directions, ripping into the many layers of detectors that logged, counted, and examined each particle.
Ten trillion particles per second.
DOLBY OPENED HIS EYES, RETURNING FROM his reverie, feeling slightly foolish. Checking his pockets for loose change or other ferromagnetic items, he walked across the staging area toward the row of electric golf carts. Isabella’s superconducting magnets were thousands of times more powerful than the ones used in medical MRI machines. They could pull a nickel right through your body or gut you with your own belt buckle.
Isabella was dangerous and demanded respect.
He climbed in behind the wheel. Pressing a button, he engaged the clutch and eased the cart into first gear.
He had designed it himself, and it was one sweet little cart. Although it could do only twenty-five miles an hour, it had cost almost as much as a Ferrari Testarossa, mostly because it had to be built entirely out of nonmagnetic materials—plastics, ceramics, and low-diamagnetic metals. It came with a communications system, a built-in computer, radar warning sensors and controllers front, side, and back, radiation sensors, ferromagnetic alarms, and a special vibration-damped bay for transporting delicate scientific instruments.
He sped across the concrete floor and entered the oval opening to the Isabella tunnel. The turn was tight and he came to a full stop.
“Hello, Isabella.”
He eased onto the concrete track that ran along the bottom of the tunnel, next to the curving bundle of pipes. Once on the track, he accelerated, the wheels staying in their grooves. Everything was bathed in greenish-blue light from a double row of fluorescent tubes overhead. As he whipped along, he glanced at the biggest pipe, gleaming 7000 aluminum-alloy construction, flanged and bolted every six feet. Inside was a vacuum harder than that found on the surface of the moon. It had to be tight: one loose atom wandering into CZero would be like a horse straying onto the racetrack at Daytona. Crash and burn.
He accelerated to top speed. The rubber wheels whispered in their grooves. Every hundred feet he passed a magnet wrapped around the pipe like a big doughnut. Each magnet, supercooled to four and a half degrees above absolute zero, wept a fog of condensation. Dolby blew through each cloud, leaving behind a whirl of eddies, the pipes racing past.
Periodically he passed a steel door on the left side of the tunnel, an opening into the old coal tunnels. Emergency exits, in case something happened. But nothing would happen. This was Isabella.
Magnet 140 was eight miles down the tunnel . . . . A twenty-minute drive. It wasn’t anything serious. Dolby was almost glad about it—he liked having time alone with his machine.
“Pretty good,” he said out loud, “for the son of a grease monkey from Watts, eh, Isabella?”
He thought of his dad, who could rebuild any car engine on earth. Never made more than the barest of livings—it was almost a crime that a fine mechanic like him never had a chance. Dolby was determined to make up for it—and he did. When Dolby was seven, his father gave him a radio kit. It seemed like a miracle, to screw and solder together a bunch of plastic and metal crap and have a voice come out. By the time he was ten, Dolby had built his first computer. Then he built a telescope, threw in a couple of CCD chips, hooked it to the computer, and began tracking asteroids. He built a tabletop accelerator using an old electron gun from a TV set. With that he achieved the alchemist’s dream, something that had eluded even Isaac Newton himself: he’d smashed a piece of lead foil with electrons, turning maybe a few hundred atoms to gold. His poor father, God rest his kindly soul, had spent every free dollar from his meager paychecks buying him kits, equipment, and parts. Ken Dolby’s dream was to build the biggest, shiniest, most expensive machine ever.
And now he had done it.
His machine was perfect, even if some bastard had hacked into the computer software.
Magnet 140 came into view and he braked hard and came to a halt. He pulled a special laptop out of the instrument bay and jacked it into a panel on the side of the magnet. Sitting on his heels, he worked on the laptop,
