There was a pause.

Then Chambers asked, "The name's Frank?"

"Yessir."

"Okay, Frank. Cop to cop: Has this individual been helpful with the case?"

Aside from one slight glitch...

Bishop responded, "Very. See, the perpetrator's a computer expert. We're no match for him without somebody like this person we've been talking about."

Another pause. Chambers said, "I'll say this -I personally don't think he's the devil incarnate like he's made out to be 'round here. There wasn't any good evidence that he cracked our system. But there're plenty of people in Washington who think he did and it's becoming a witch-hunt in the department here. If he did anything illegal he'll go to jail. But I'm on the side that he's innocent until proven otherwise."

"Yessir," Bishop said, then added delicately, "Of course, you could also look at it that if some kid could crack the code maybe you might want to write a better one."

The detective thought: Okay, now, that remark may just get me fired.

But Chambers laughed. He said, "I'm not sure Standard 12 is all it's touted to be. But there're a lot of people involved in encryption here who don't want to hear that. They don't like to get shown up and they really hate it if they get shown up in the media. Now, there's an a.s.sistant undersecretary, Peter Kenyon, who'd s.h.i.t bricks if he thought there was a chance our unnamed individual was out of prison and might end up on the news. See, Kenyon was the one in charge of the task force that commissioned Standard 12."

"I was wondering."

"Kenyon doesn't know the boy's out but he's heard rumors and if he does find out it could be bad for me and for a lot of people." He let Bishop mull these intra-agency politics over for a moment. Chambers then said, "I was a cop before I got into this bureaucracy stuff."

"Where, sir?"

"I was an M.P. in the navy. Spent most of my time in San Diego."

"Broke up some fights, did you?" Bishop asked.

"Only if the army was winning. Listen, Frank, if that boy is helping you catch this perp, okay, go ahead. You can keep him until the release order expires."

"Thank you, sir."

"But I don't need to tell you that you're the one who'll get hung out to dry if he hacks into somebody's Web site. Or if he disappears."

"I understand, sir."

"Keep me informed, Frank."

The phone went dead.

Bishop hung up, shook his head.

Sorry...

"What was that all about?" Shelton asked.

But the detective's explanation was interrupted when they heard a triumphant shout from Miller. "Got something here!" he called excitedly.

Linda Sanchez was nodding her weary head. "We've managed to recover a list of Web sites Gillette logged on to just before he escaped."

She handed Bishop some printouts. They contained a lot of gibberish, computer symbols and fragments of data and text that made no sense to him. But among the fragments were references to a number of airlines and information about flights that evening from San Francisco International to other countries.

Miller handed him another sheet of paper. "He also downloaded this - the schedule of buses from Santa Clara to the airport." The pear-shaped detective smiled with pleasure -presumably at having recovered from his earlier b.u.mbling.

"But how would he pay for the airfare?" Shelton wondered out loud.

"Money? Are you kidding?" Tony Mott asked with a sour laugh. "He's probably at an ATM right now, emptying your bank account."

Bishop had a thought. He went to the phone in the a.n.a.lysis lab and picked it up, hit REDIAL.

The detective spoke with someone on the other end of the line for a moment. Then he hung up.

Bishop reported his conversation to the team. "The last number Gillette dialed was a Goodwill store a couple of miles from here in Santa Clara. They're closed but the clerk's still there. He said somebody fitting Gillette's description came in about twenty minutes ago. He bought a black trench coat, a pair of white jeans, an Oakland A's cap and a gym bag. He remembered him because he kept looking around and seemed really nervous. Gillette also asked the clerk where the nearest bus stop was. There's one near the store and the airport bus does stop there."

Mott said, "It takes the bus about forty-five minutes to get up to the airport." He checked his pistol and started to rise.

"No, Mott," Bishop said. "We've been through this before."

"Come on," the young man urged. "I'm in better shape than ninety percent of the rest of the force. I bicycle a hundred miles a week and I run two marathons a year."

Bishop said, "We're not paying you to run Gillette to ground. You stay here. Or better yet go home and get some rest. You too, Linda. Whatever happens with Gillette we're still going to be working overtime to find the killer."

Mott shook his head, not at all happy about the detective's order. But he agreed.

Bob Shelton said, "We can be at the airport in twenty minutes. I'll call in his description to the Port Authority police. They'll cover all the bus stops. But I tell you - I'm personally going to be at the international terminal. I can't wait to see the look in that man's eyes when I say h.e.l.lo." The stocky detective cracked the first smile Bishop had seen in days.

CHAPTER 00010100 / TWENTY.

Wyatt Gillette stepped off the bus and watched it pull away from the curb. He looked up into the night sky. Specters of clouds moved quickly overhead and sprinkled droplets of cold rain on the ground. The moisture brought out the smells of Silicon Valley: auto exhaust and the medicinal scent of eucalyptus trees.

The bus - which wasn't bound for the airport at all but was making local stops in Santa Clara County - had deposited him on a dark, empty street in the pleasant suburb of Sunnyvale. He was a good ten miles from the San Francisco airport, where Bishop, Shelton and a slew of police officers would be frantically searching for an Oakland A's fan in white jeans and a black raincoat.

As soon as he'd left the Goodwill store he'd pitched out those clothes and had stolen what he now wore - a tan jacket and blue jeans - from the collection box in front of the shop. The canvas gym bag was the only purchase still with him.

Opening his umbrella and starting up a dimly lit street, Gillette inhaled deeply to calm his nerves. He wasn't worried about recapture - he'd covered his tracks at CCU just fine, logging on to airline Web sites, looking up international flight information then running EmptyShred - to catch the attention of the team and to draw them to the fake clues he'd planted about leaving the country.

No, Gillette was nervous as h.e.l.l because of where he was now headed.

It was after 10:30 and many of the houses in this hardworking town were dark, their owners already asleep; days begin early in Silicon Valley.

He walked north, away from El Camino Real, and soon the sound of traffic on that busy commercial street faded.

Ten minutes later he saw the house and slowed down.

No, he reminded himself. Keep going... Don't act suspicious. He started walking again, eyes on the sidewalk, avoiding the glances of the few people on the street: A woman in a silly plastic rain hat, walking her dog. Two men hunched over a car's open hood. One held an umbrella and flashlight while the other struggled with a wrench.

Still, as he drew closer to the house - an old cla.s.sic California bungalow - Gillette found his steps slowing until, twenty feet away, he stopped altogether. The circuit board in the gym bag, which weighed only a few ounces, seemed suddenly to be heavy as lead.

Go ahead, he told himself. You have to do it. Go on.

A deep breath. He closed his eyes, lowered the umbrella and looked upward. He let the rain fall on his face.

Wondering if what he was about to do was brilliant or completely foolish. What was he risking?

Everything, he thought.

Then he decided that it didn't matter. He had no choice.

Gillette started forward, toward the house.

No more than three seconds later they nailed him.

The dog walker turned suddenly and sprinted toward him, the dog - a German shepherd - growling fiercely. A gun was in the woman's hand and she was shouting, "Freeze, Gillette! Freeze!"

The two men supposedly working on the car also drew weapons and raced toward him, shining flashlights in his eyes.

Dazed, Gillette dropped the umbrella and the gym bag. He lifted his hands and backed up slowly. He felt someone grip his shoulder and he turned. Frank Bishop had come up behind him. Bob Shelton was there too, holding a large black pistol pointed at his chest.

"How did youa"?" Gillette began.

But Shelton lashed out with his fist and struck Gillette squarely in the jaw. His head popped back and, stunned, he fell hard to the sidewalk.

Frank Bishop handed him a Kleenex, nodded toward his jaw.

"You missed some there. No, to the right."

Gillette wiped the blood away.

Shelton's punch hadn't been that hard but his knuckles had cut skin and the rain flowed into it, making the wound sting fiercely.

Other than offering the tissue, Bishop gave no reaction to the blow delivered by his partner. He crouched, opened the canvas bag. He took out the circuit board. He turned it over and over in his hands.

"What is it, a bomb?" he asked with a lethargy that suggested he didn't think it was explosive.

"Just something I made," Gillette muttered, pressing his palm to his nose. "I'd rather you didn't get it wet."

Bishop stood, put it in his pocket. Shelton, his scarred face wet and red, kept staring at him. Gillette tensed slightly, wondering if the cop was going to lose control and hit him again.

"How?" Gillette asked again.

Bishop said, "We were on the way to the airport but then I started thinking. If you'd really gone online and looked up something about where you were going, you'd've just destroyed the hard drive and done it as soon as you left. Not timed that program to run later. Which all it did was draw our attention to the clues you'd left about the airport. Like you'd planned, right?"

Gillette nodded.

The detective then added, "And why on earth would you pretend to go to Europe? You'd get stopped at customs."

"I didn't have a lot of time to plan," Gillette muttered.

The detective looked up the street. "You know how we found out you were coming here, don't you?"

Of course he knew. Bishop had called the phone company and learned what number had been dialed from the phone in the lab before he'd called Goodwill. Then Bishop had gotten the address of that location - the house in front of them - and they'd staked out the approaches.

If Bishop's handling of the escape had been software, the hacker within Gillette would have called it one moby kludge.

He said, "I should've cracked the switch at Pac Bell and changed the local-call records. I would've done that if I'd had time."

Shock at the arrest was diminishing, replaced by despair - as he looked at the outline of his electronic creation in Bishop's raincoat pocket. How close he'd come to the goal that had obsessed him for months. He looked at the house he'd been headed for. The lights glowed warmly, beckoning.

Shelton said, "You're Shawn, aren't you?"

"No, I'm not. I don't know who Shawn is."

"But you were Valleyman, right?"

"Yes. And I was in the Knights of Access."

"You know Holloway?"

"I did know him, yes."

"Jesus Christ," the bulky detective continued, "of course you're Shawn. All you a.s.sholes have a dozen different IDs. You're him and you're on your way to meet Phate right now." He grabbed the hacker by the collar of his cheap Goodwill jacket.

This time Bishop intervened and touched Shelton's shoulder. The big cop released the hacker but continued in his low, threatening voice, nodding at the house up the street. "Phate's going by the ident.i.ty of Donald Papandolos. He's the one you called - and you called him a couple of times today from CCU. To tip him off about us. We saw the f.u.c.king phone records."

Gillette was shaking his head. "No. I-- Shelton continued, "We've got tactical troopers surrounding the place. And you're going to help us get him out."

"I have no idea where Phate is. But I'll guarantee you he's not in there."

"Who is, then?" Bishop asked.

"My wife. That's her father's house."

CHAPTER 00010101 / TWENTY-ONE.

Elena's the one I called," Gillette explained. He turned to Shelton. "And you were right. I did go online when I first got to CCU. I lied about it. I hacked into DMV to see if she was still living at her father's. Then I called her tonight to see if she was home."
