Prologue

FBI Special Agent Natasha Rudolph drew her FBI-issued Glock .23 and eyed the burned-out building in a run-down section of downtown Washington, D.C. The broken door hung off its hinges, and as she entered, weapon first, the smell of smoke, urine and dead rats hit her like a noxious wind.

Her wrist communicator beeped quietly.

“Natasha, damn it, where are you?”

It was Storm.

“I just got here,” she whispered into her COM unit. “The cell phone signal had to come from this building.”

“I’m right behind you. Three minutes. Wait for me.”

She knew from experience that in three minutes, Bobby Lee Hutchins could be long gone.

She and fellow Agent Ray Storm had been tracking Hutchins for months, since he’d detonated an explosive device in the Mall in Washington, D.C., that had killed two people and injured over a dozen, including the daughter of a prominent U.S. congressman.

Hutchins was clever, but Natasha and Storm had finally located his mother and tapped her phone. Now they had him, and Natasha wasn’t about to let him slip away again.

“Natasha! Answer me!”

After an instant’s hesitation, she muted the wrist COM’s speaker and stepped into the dim, suffocating interior of the building, her weapon ready.

As she skirted a pile of broken glass, she heard a noise above her head. She froze, tightening her grip on her weapon.

Without moving, she examined the area. She spotted holes in the ceiling, glass and debris on the floor, fire and water damage everywhere.

Carefully, her ears attuned to the smallest sound, she started up the wobbly staircase. Something moved in the darkness beyond the stairs. Natasha jerked, but it was just a mouse. She blew out a breath of relief. She was after human vermin.

Her wrist COM lit up. Storm—trying to reach her again. She ignored it. Hutchins had slipped out of their hands too many times. She wasn’t about to lose him this time because protocol dictated she wait for backup. Agents were supposed to use their best discretion in urgent situations.

The sound of wood scraping against wood above her head sent her heart hammering in anticipation.

He was up there. She silently eased her way up the rickety stairs, careful to avoid broken steps. The creak of a board under her boot froze her in place. She stood awkwardly poised between two steps, not daring to breathe. After a few seconds of silence, she moved forward.

As she approached the second floor, she crouched low, taking the steps at a crawl, then slowly raised her head and her gun. Sucking in a deep breath, she prayed Storm really was only seconds away.

She jumped up, swinging her weapon in an arc, checking all sides. Nothing.

Cautiously, she angled around the banister.

A soft thump from behind had her wheeling around. A man threw all his weight against her, knocking her to the floor. She twisted as she fell, getting off a shot, but it went wild.

Screaming like a madman, Hutchins swung a rifle barrel at her head. Blinding pain wiped out her vision for an instant. She grasped her Glock desperately.

Then he was over her, the barrel of his rifle digging into her abdomen.

“You shouldn’a gone after my ma!” he screamed.

Natasha pointed her weapon at his chest and struggled to breathe. “Put down the gun!” she gasped.

Hutchins laughed. “You gonna make me?”

“Drop it now or I’ll shoot!” Her voice cracked with fear, but she couldn’t back down. She didn’t want to die. Not today.

He took a step back, and Natasha recognized the instinctive move—he was putting distance between himself and his victim.

“Last chance, Hutchins. Drop it!” she yelled.

His grimy finger tightened on the trigger.

She fired.

Hutchins staggered and blood blossomed on the front of his dirty T-shirt.

She scrambled up, her head spinning.

He recovered and rushed her. Before she could get off another shot, he head-butted her in the gut and her back slammed against the banister. With a loud crack, the railing broke.

Then she was falling—falling. She hit the stairs. Splinters rained around her as her weight broke through the rotten charred wood. Frantically she tried to cushion her landing, but a piece of wood stabbed her hand and her head slammed against a step’s solid frame.

A section of floor disintegrated under her weight.

Then with a jarring thud she hit bottom. The impact knocked the breath out of her. A ridge of hard-packed dirt dug into her back.

She looked up. She’d fallen through to the basement. Two floors above, Hutchins raised his rifle. Natasha tried to roll out of his range of vision, but a massive board pinned her legs.

She watched in horrified fascination as his finger tightened on the trigger. She spotted a board she could use as a shield, but she couldn’t reach it.

She felt the impact as the bullet slammed into her. The report was deafening. Her stomach lurched at the feel of hot sticky blood pooling in the hollow of her shoulder, and she wondered why it didn’t hurt.

Then it did. Pain ripped her in two, stole the last of her breath. Hutchins raised his rifle again. Instinct took over and her fingers tightened on the trigger. She looked down at her hand, surprised she still held the gun.

Gathering the last of her strength, she lifted her arm. Aiming the gun at Hutchins’s leering face, she pulled the trigger.

A horrible rumbling filled her ears. Dust and wood and drywall rained down on her. She struggled to move, but her body wouldn’t cooperate. The cold dirt beneath her and the heavy, suffocating debris on top of her threatened to crush her. Dust and grit filled her eyes. She couldn’t see.

She was trapped. Buried alive.

She screamed and pushed at the jagged boards and piles of drywall and broken glass weighing her down. A sharp edge cut into her palm. Drywall dust coated her throat. Soot caught in her nostrils.

Buried.

Panic threw her into insanity. She screamed until her throat swelled and her mouth was full of soot and dirt. Tears soaked up the dust and caked like concrete on her cheeks.

Terror crowded all rational thought from her brain. The past welled up to suck her into childhood horrors.

She was back in the mangled smoking car, the air thick with the moans of her dying parents, her face and body slick with their blood, her little arms and legs pinned beneath twisted metal.

Her screams mixed with the echo of explosions and gunfire.

But no matter how loud she screamed, nobody came.

Chapter One

Dylan Stryker looked down at his sleeping son. He’d been working with the virtual surgery program and missed Ben’s bedtime again.

In the dim glow of a caterpillar night-light, he watched his little boy’s lips move slightly with each gentle breath. He looked so small, so innocent—so vulnerable.

Dylan’s heart squeezed with guilt and grief and stinging regret. Looking away, his gaze landed on Ben’s leg braces in the corner. In stark contrast to his son’s softly lit face, the ultralight titanium sucked up the light greedily, shining with the stark whiteness of bones. They mocked him, a constant reminder that his child’s handicap was his fault.

Irony twisted his gut. He’d been named a hero for inventing the computer-driven leg supports. Now his own child couldn’t walk without them, and it was because of him. He knelt and kissed Ben’s cool cheek.

“I love you,” he whispered. “I’d die for you if it would change the past.”

The bedroom door opened. It was Alfred.

Dylan’s senses went on full alert. His chief of security never interrupted him when he was with his son. He slipped quietly through the door to the hall.

“Sorry,” Alfred said shortly.

“What is it? Another breach of the fence?” Next week was the third anniversary of the suspicious car crash that had killed his wife and injured his child. The vehicle that had run her off the road had never been found. And despite his and the government’s best efforts to cover up Ben’s survival, this time each year the tabloids always rehashed the sensationalistic rumors surrounding the crash.

Alfred shook his head at the latest headline, his weathered face grim. “Campbell called me,” he said. “We’ve been hacked.”

Dylan cursed. “How bad?”

“In and out within a few seconds, according to Campbell. I should have waited until morning. Should have let you sleep.” Alfred’s face was lined with worry.

“No. I wasn’t asleep. I need to know as soon as anything happens.”

“What for? So you have something else on your mind to keep you from sleeping? You couldn’t have stopped the hacker.”

Dylan headed for the back stairs. “I could have tried.”

Alfred followed, laying a hand on Dylan’s arm. “He’s gone now. Go back to Ben. Try to get some sleep.”

“I can’t sleep. You know that. I might as well work.” Dylan rubbed his burning eyes.

“Son, this is almost certainly a domestic terrorist cell. Why don’t you take NSA up on their offer of protection?”

Dylan sighed. “I talked to them today.”

“You’ve decided to move to a secure location?” Hope tinged Alfred’s gravelly voice. As proud as the ex-military man was of his security measures, he’d made it clear that he’d prefer having Dylan and Ben under the government protection.

Dylan shook his head and rubbed the back of his neck. “We’ve had this conversation. I’m not sending Ben away. And I can’t go with him. The interface hardware is at a critical point—too delicate to be moved, and we’re still debugging the software. I can’t afford to lose even a couple of days….” He heard the desperation in his own voice. Alfred knew as well as he did the real reason he was working night and day.

Time was running out for Ben.

“So why’d you call NSA?”

“I told them that if they want their damn supersoldier technology, they’ll find me the best computer expert in the country. They promised me someone within forty-eight hours.”

SPECIAL AGENT Natasha Rudolph wiped her palms down her slacks as the doors slid shut, locking her in an elevator that was about to take her underground. Mitch Decker, Special Agent in Charge, had warned her this assignment would be difficult.

However, he hadn’t mentioned that the computer lab where she’d be working was twelve feet belowground on a secluded estate in the Hamptons. She closed her eyes as the elevator started downward.

“Agent Rudolph?”

She opened her eyes to find the military type who’d met her at the front door eyeing her hands. She realized she was clenching her fists.

“Yes? Mintz, isn’t it?” She deliberately relaxed her fingers. “I’m fine. Looking forward to getting started. It’s been a long day.” She bit her lip. She sounded like a babbling idiot. She set her jaw and silently commanded her heart to stop fluttering and her hands to stay serenely at her sides.

Alfred Mintz frowned at her as the elevator doors slid silently open.

She wiped her palms again, and stepped out into a brightly lit hall. It looked as if all the walls were made of glass. Natasha swallowed nervously. Not very substantial. She resisted the urge to glance up at the ceiling. How did these walls hold up the tons of dirt and steel above their heads?

Ignoring the burning sensation on her scalp that signaled rising panic, she concentrated on staying calm.

Mintz started down the hall, leaving her to catch up. “You may not get to meet Dr. Stryker tonight. If he’s in the virtual surgery lab, we won’t disturb him.”

They passed empty offices, furnished cubicles with computer workstations, and a door labeled Restroom And Showers that thankfully was not walled with glass.

“I thought he was anxious for me to get started reinforcing the firewall,” she said.

Just past the restroom was a longer, solid glass wall. She saw a dim glow through the glass, although the glare of the brighter hall lights kept her from seeing inside the room clearly. She had the impression of chrome and steel.

Mintz stopped at the door. He nodded, his gaze on something or someone beyond the glass.

Natasha shaded her eyes and squinted. The room was an exercise room—a very well-equipped exercise room.

And as she watched, a very well-equipped man stepped off a treadmill and grabbed a towel.

A few seconds later, the man stepped through the glass door and walked toward her with loose-limbed grace. He wore a gray T-shirt and gray exercise pants. The T-shirt was dark with sweat, and hugged the planes of his chest and shoulders. Its tail hung loose, hinting at a flat, ridged belly. The pants fit snugly over his lean hips and long legs.

His biceps flexed as he toweled his face and hair, then slung the towel around his neck.

Natasha gaped at him. Who was he? Not Stryker, surely. This guy did not look like a famous neurosurgeon. Maybe he was the young bioengineer she’d been told was building the interface implant—Jerry Campbell.

Mintz stepped aside as he approached.

When Natasha pulled her gaze away from his sweaty, sexy body and met his gaze, the lines around his red-rimmed blue eyes and the exhaustion on his face came into focus.

This was no kid. But, who—

His sharp blue eyes burned into hers.

“Dylan Stryker, this is Special Agent Natasha Rudolph,” Mintz said.

“Ah, yes. NSA said you’d be here by this evening,” Stryker said wryly, lifting one brow.

It was him. “Well, NSA and the FBI tend to respond more favorably to requests than demands.”

“I don’t have time to wait for the bureaucracy to process a request.”

His gaze flickered down her body and back up. Then he held out his hand. “So you’re the best hacker-buster in the known universe.”

She stared at the elegantly long, blunt-tipped fingers and neatly trimmed nails. His hands were the only thing about him that fit the information she’d been given. They looked like surgeon’s hands.

The only recent photos of him were long-range, grainy tabloid shots. From them she’d gotten the impression of a thin, hatchet-faced, obsessed scientist.

Boy was she wrong!

“Hacker-buster?” She shook her head. “No. Computer expert.” Her voice was steadier than her insides.

This was Dylan Stryker. Her head spun as lurid headlines filled her vision.

Underground Dungeon.

It was typical tabloid fare and it made her shudder each time she thought about it, made her dread meeting Stryker’s child, whom Decker had told her was paralyzed. How could anyone keep a child in this place? Underground dungeon—underground lab. Close enough.

“Dr. Stryker.” She took his extended hand, and his intensity hit her like the back draft from a fire. Shock and awareness skittered along her spine. His grasp was firm and brief, leaving her palm feeling singed by his touch.

“So, Agent Rudolph, are you really the best?” His voice held a challenge.

“Yes, I am,” she said without hesitation.

His straight mouth tilted slightly at one corner. “Good. Perfect.”

He nodded, dislodging a trickle of sweat that slid down over his temple and down his jawbone.

He glanced at his watch, used the towel on his damp hair again, then turned to Mintz. “Get her settled and put her to work. What about equipment?”

“Brought it with her. Where do you want her?”

“In the office across from the virtual surgery lab.” He pointed farther down the hall. Then he looked at her. “How much equipment do you have?”

“I’d rather have an office upstairs—” Natasha started, but Mintz was listing her equipment for Stryker. Neither one of them paid any attention to her.

“Is there anything else you need, Agent Rudolph?”

Windows. Lots of windows. “Any chance I could work upstairs somewhere?”

“No. Out of the question.” Stryker eyed her suspiciously. “Are you sure you can handle this job?”

“Yes, of course,” she said, thankful her voice was still steady. She had a job to do. And that meant forgetting that there were truckloads of dirt and an entire mansion over her head. Her career was on the line. She had to succeed—windows or no windows.

“I assume I can start right away.” The quicker she got started, the quicker she could expose the hacker and get out of this hole in the ground.

“Alfred’ll take care of anything you need,” Stryker said with a wave of his hand.

As he turned away, his gaze met hers in a fleeting, intense glance that seared her to the bone. His clear blue eyes burned as brightly as an oxygen flame, warming her cheeks and stirring a cauldron of unexpected emotions within her.

He might be tired and unkempt, underfed and distracted, but Dylan Stryker exuded an air of command and—she searched for the right word…masculinity…that hummed through her like the ring of a perfectly pitched tuning fork. She blinked and dropped her gaze.

“Thanks, Alfred.” Stryker headed back to his lab.

Natasha felt stunned. According to his file, Stryker was thirty-three, and already known worldwide for his breakthroughs with computer-assisted mobility in nerve-damaged patients.

Natasha had studied everything the FBI had on him, including clippings from the tabloids. He’d been thirty when his wife was killed three years before.

It has long been rumored that Stryker’s infant son did not die in the mysterious car crash that killed his wife….

Natasha stared at Stryker’s broad shoulders and lean hips until she realized Mintz had left her behind again. She hurried to catch up. He used his thumbprint and keyed in digits from a pass code generator. The door clicked open to reveal a small foyer banked with elevators.

“Where are we going? I need to start work.”

Mintz punched the call button. “I’ll show you to your room first, so you can freshen up. Have you eaten?”

She nodded, finding it difficult to pull her thoughts away from Dylan Stryker. He was so completely different from her expectations. He was driven, maybe even obsessed. But there was something else about him. Something dark and haunted lurked behind his brilliant blue eyes.

“I assume you’ve been fully briefed on our situation?” Mintz asked.

“Yes, sir. I’m here to stop a hacker and construct a firewall. And of course, to help with physical security.”

Mintz shook his head. “Physical security is not your job. Two of your fellow agents are on the outside to help my staff handle that. You concentrate on the computer.”

Irritation stiffened her shoulders. “I’ve studied the aerial photos. You’ve done a good job of camouflaging the house.”

Too good for her taste. This was her first assignment since her injury. And now she understood why Decker had given her a choice. He’d told her that the staff psychiatrist had declared her minimally qualified. At the time she was furious, and eager to prove the shrink wrong.

Now she got it. How ironic that this job tapped into her worst fears. Before her injury, this would have been just another assignment, and her mild claustrophobia would be manageable. But now she was fighting for her career. If she couldn’t conquer her irrational fear of closed spaces, she’d lose her job.

She suppressed a shudder, drew in a lungful of conditioned air and repeated the mantra Dr. Shay had given her to calm her panic.

Quiet and safe. Plenty of fresh air. Breathe. Breathe. Breathe.

It was nighttime now, but she knew from the photos Decker had shown her that even during the day, the massive house was shrouded in darkness. “I saw the infrared photos. How do you keep from broadcasting body heat?”

“The canopy that stretches over the entire house is made of a specially designed heat-repelling mesh,” Mintz answered. “Some sunlight does get in. But it’s very good camouflage.”

“Right. The perfect hiding place,” she said wryly.

“Not perfect,” Mintz responded. “We do what we can to quash any rumors that this is Dylan’s base of operations. But occasionally somebody tries to breach the walls, or flies over in a helicopter. Usually paparazzi.”

The faint note of disapproval in his voice intrigued her. She looked at him, but his stern face gave away nothing.

The elevator doors opened and they stepped inside.

“And now it looks like we’ve got a hacker.”

“Did I understand that your computer guy said he got in and out clean?”

He nodded. “Jerry Campbell. He’s the bioengineer working with Dylan. He assured us the hacker left nothing behind.”

“Bioengineer? Who’s handling the computer system?”

Mintz cleared his throat impatiently. “Dr. Stryker wants as few people involved as possible.”

“I don’t know how good a bioengineer he is but he’s wrong about the hackers. They always leave something,” Natasha said firmly. “I need to talk with him, find out what he saw.”

“Tomorrow.”

“Why not tonight? What he tells me will help determine what other equipment I’ll need.”

Mintz shook his head. “He’s busy with Dylan tonight.”

“Well, maybe when he takes a break,” she said impatiently. She needed to get finished and get out. The assignment was already giving her the creeps.

The FBI shrink’s evaluation taunted her. Hasn’t fully dealt with her claustrophobia. She had to defeat the feeling of losing control if she was going to succeed.

“Believe me, Agent Rudolph. We’re anxious for you to get started. Get the equipment you brought set up tonight. Assess the system. Decide what else you need. Then first thing tomorrow, you can meet Campbell and have him brief you on the hacker’s movements.”

Natasha started to press him, but he held up his hand.

“Dylan’s at a critical point in the debugging process right now. I’m surprised he stopped long enough to exercise, although with the amount of tension he’s carrying around…” Mintz set his jaw. “He needs you, but he resents the time it’s going to take to bring you up to speed. Time is the one thing he doesn’t have. If you’re as good as your superiors say you are, he’ll figure it out soon enough.”

She tried one last frontal attack. “NSA is extremely anxious to get their hands on that interface.”

“NSA is not Dylan’s primary concern.”

Before she could ponder that comment, the elevator doors slid open, and they stepped out into the atrium through which she’d entered. It was laid out in brightly veined Italian marble. A mezzanine lined with bookshelves bisected the walls.

The high ceiling was crowned by a massive domed skylight. Although the sun had set, a pink and purple glow filtered through the glass dome.

“I assume the skylight is shielded, too?”

Mintz glanced up. “Yep. The mesh doesn’t block the moon and stars as much as it does the sun. And there’s clear plastic sheeting to keep out the rain while allowing a little sunlight in.”

The vise that had squeezed her chest since she got here loosened a bit. She took a long cleansing breath. At least she could see the sky—sort of.
