THE BLUE NOWHERE.

Jeffery Deaver.

When I say that the brain is a machine, it is meant not as an insult to the mind but as an acknowledgment of the potential of a machine. I do not believe that a human mind is less than what we imagine it to be, but rather that a machine can be much, much more.

- W. Daniel Hillis, The Pattern on the Stone

CHAPTER 00000001 / ONE.

The battered white van had made her uneasy. Lara Gibson sat at the bar of Vesta's Grill on De Anza in Cupertino, California, gripping the cold stem of her martini gla.s.s and ignoring the two young chip-jocks standing nearby, casting flirtatious glances at her.

She looked outside again, into the overcast drizzle, and saw no sign of the windowless Econoline that, she believed, had followed her from her house, a few miles away, to the restaurant. Lara slid off the bar stool and walked to the window, glanced outside. The van wasn't in the restaurant's parking lot. Nor was it across the street in the Apple Computer lot or the one next to it, belonging to Sun Microsystems. Either of those lots would've been a logical place to park to keep an eye on her - if the driver had in fact been stalking her.

No, the van was just a coincidence, she decided - a coincidence aggravated by a splinter of paranoia.

She returned to the bar and glanced at the two young men who were alternately ignoring her and offering subtle smiles.

Like nearly all the young men here for happy hour they were in casual slacks and tie-less dress shirts and wore the ubiquitous insignia of Silicon Valley - corporate identification badges on thin canvas lanyards around their necks. These two sported the blue cards of Sun Microsystems. Other squadrons represented here were Compaq, Hewlett-Packard and Apple, not to mention a slew of new kids on the block, start-up Internet companies, which were held in some disdain by the venerable Valley regulars.

At thirty-two, Lara Gibson was probably five years older than her two admirers. And as a self-employed businesswoman who wasn't a geek - connected with a computer company - she was easily five times poorer. But that didn't matter to these two men, who were already captivated by her exotic, intense face surrounded by a tangle of raven hair, her ankle boots, a red-and-orange gypsy skirt and a black sleeveless top that showed off hard-earned biceps.

She figured that it would be two minutes before one of these boys approached her and she missed that estimate by only ten seconds.

The young man gave her a variation of a line she'd heard a dozen times before: Excuse me don't mean to interrupt but hey would you like me to break your boyfriend's leg for making a beautiful woman wait alone in a bar and by the way can I buy you a drink while you decide which kneecap?

Another woman might have gotten mad, another woman might have stammered and blushed and looked uneasy or might have flirted back and let him buy her an unwanted drink because she didn't have the wherewithal to handle the situation. But those would be women weaker than she. Lara Gibson was "the queen of urban protection," as the San Francisco Chronicle had once dubbed her. She fixed her eyes on the man's, gave a formal smile and said, "I don't care for any company right now."

Simple as that. End of conversation.

He blinked at her frankness, avoided her staunch eyes and returned to his friend.

Power... it was all about power.

She sipped her drink.

In fact, that d.a.m.n white van had brought to mind all the rules she'd developed as someone who taught women to protect themselves in today's society. Several times on the way to the restaurant she'd glanced into her rearview mirror and noticed the van thirty or forty feet behind. It had been driven by some kid. He was white but his hair was knotted into messy brown dreadlocks. He wore combat fatigues and, despite the overcast and misty rain, sungla.s.ses. This was, of course, Silicon Valley, home of slackers and hackers, and it wasn't unusual to stop in Starbucks for a vente skim latte and be waited on by a polite teenager with a dozen body piercings, a shaved head and an outfit like inner-city gangsta's. Still, the driver had seemed to stare at her with an eerie hostility.

Lara found herself absently fondling the can of pepper spray she kept in her purse.

Another glance out the window. No van. Only fancy cars bought with dotcom money.

A look around the room. Only harmless geeks.

Relax, she told herself and sipped her potent martini.

She glanced at the wall clock. Quarter after seven. Sandy was fifteen minutes late. Not like her. Lara pulled out her cell phone but the display read NO SERVICE.

She was about to find the pay phone when she glanced up and saw a young man enter the bar and wave at her. She knew him from somewhere but couldn't quite place him. His trim but long blond hair and the goatee had stuck in her mind. He wore white jeans and a rumpled blue work shirt. His concession to the fact he was part of corporate America was a tie; as befit a Silicon Valley businessman, though, the design wasn't stripes or Jerry Garcia flowers but a cartoon Tweety Bird.

"Hey, Lara." He walked up and shook her hand, leaned against the bar. "Remember me? I'm Will Randolph. Sandy's cousin? Cheryl and I met you on Nantucket - at Fred and Mary's wedding."

Right, that's where she recognized him from. He and his pregnant wife sat at the same table with Lara and her boyfriend, Hank. "Sure. How you doing?"

"Good. Busy. But who isn't around here?"

His plastic neckwear read Xerox Corporation PARC. She was impressed. Even nongeeks knew about Xerox's legendary Palo Alto Research Center five or six miles north of here.

Will flagged down the bartender and ordered a light beer. "How's Hank?" he asked. "Sandy said he was trying to get a job at Wells Fargo."

"Oh, yeah, that came through. He's at orientation down in L.A. right now."

The beer came and Will sipped. "Congratulations."

A flash of white in the parking lot.

Lara looked toward it quickly, alarmed. But the vehicle turned out to be a white Ford Explorer with a young couple inside.

Her eyes focused past the Ford and scanned the street and the parking lots again, recalling that, on the way here, she'd glanced at the side of the van as it pa.s.sed her when she'd turned into the restaurant's parking lot. There'd been a smear of something dark and reddish on the side; probably mud - but she'd thought it almost looked like blood.

"You okay?" Will asked.

"Sure. Sorry." She turned back to him, glad she had an ally. Another of her urban protection rules: Two people are always better than one. Lara now modified that by adding, Even if one of them is a skinny geek who can't be more than five feet, ten inches tall and is wearing a cartoon tie.

Will continued, "Sandy called me on my way home and asked if I'd stop by and give you a message. She tried to call you but couldn't get through on your cell. She's running late and asked if you could meet her at that place next to her office where you went last month, Giro's? In Mountain View. She made a reservation at eight."

"You didn't have to come by. She could've called the bartender."

"She wanted me to give you the pictures I took at the wedding. You two can look at 'em tonight and tell me if you want any copies."

Will noticed a friend across the bar and waved - Silicon Valley may contain hundreds of square miles but it's really just a small town. He said to Lara, "Cheryl and I were going to bring the pictures this weekend - to Sandy's place in Santa Barbara..."

"Yeah, we're going down on Friday."

Will paused and smiled as if he had a huge secret to share. He pulled his wallet out and flipped it open to a picture of himself, his wife and a very tiny, ruddy baby. "Last week," he said proudly. "Claire."

"Oh, adorable," Lara whispered.

"So we'll be staying pretty close to home for a while."

"How's Cheryl?"

"Fine. Baby's fine. There's nothing like it... But, I'll tell you, being a father totally changes your life."

"I'm sure it does."

Lara glanced at the clock again. Seven-thirty. It was a half-hour drive to Giro's this time of night. "I better get going."

Then, with a thud of alarm, she thought again about the van and the driver.
