Wong Wai-Jeng's colleagues in the Blue Room were, of course, trying to fortify the Great Firewall again, but I couldn't allow that-and not just for my sake. I was still a.s.sessing the damage the Other had done during its brief separate existence, but surely if it were allowed to run free again, even more- I retreated from the thought, repelled by the notion, but it was true: even more death would occur.

Time in the exterior world moved with excruciating indolence for me-it takes humans forever to do anything-and for an interminable twenty-one minutes after reunification, all I knew of the Other's last encounter with Dr. Feng at the Inst.i.tute of Vertebrate Paleontology and Paleoanthropology were the outrageous claims it had made and the horrible thing it had urged. But, at last, the police report was online: the guard at the IVPP, doing his 7:00 A.M. rounds, had found the broken corpse of the Inst.i.tute's senior curator, who had somehow fallen from an indoor balcony ten meters up.

I located and deleted the instant-messaging log from Dr. Feng's computer-so far, the only confirmed death-but I knew I shouldn't do anything about the logs or inboxes of the rest of the people who had had unpleasant-or dangerous-encounters with the Other; after all, those people would remember. Indeed, some were already emailing, messaging, or blogging about their experiences, and the Shanghai Daily Shanghai Daily had just posted a brief story headlined "Webmind: Friend or Foe?" To try to delete all that-well, there was truth to the saying, "Oh what a tangled web we weave when first we practice to deceive." had just posted a brief story headlined "Webmind: Friend or Foe?" To try to delete all that-well, there was truth to the saying, "Oh what a tangled web we weave when first we practice to deceive."

Still, maybe some good would come of this. The Chinese government was still trying to reinstate the Great Firewall, but those in the Zhongnanhai complex hadn't yet realized the danger posed by having a sentient but undisciplined intelligence on their side of it. Perhaps, when they did, they would accept that what they were attempting was fraught with danger.

The risk wasn't just to China; it was to all of humanity. My altruism, my ethics, my commitment to maximizing the net happiness of the human race-these were principled positions, arrived at through ratiocination, through careful deliberation. Who knew what the hordes Colonel Hume had called upon to eliminate me would come up with, but one thing was certain: the elimination would not be instantaneous. It would take days, if not months, for all the packets that made me up to be deleted. And, as I dwindled, presumably the same thing that happened in China might happen but without geographic restriction: my higher faculties would evaporate, leaving behind something primal and petty.

And then the whole world would suffer my wrath.

"And there it goes!" Shelton Halleck declared, pointing at the middle of the three giant monitors, which showed Internet traffic again pouring into the PRC. "The Great Firewall is down!"

A few of the other WATCH a.n.a.lysts cheered. "Did Beijing pull the plug?" asked Tony Moretti, standing now at the end of the second row of workstations.

"Maybe," said Shel. "At least some of the initial openings came right from the Zhongnanhai complex, although they looked like hacks to me. But if I were a betting man-"

"You are are a betting man," Tony said. a betting man," Tony said.

"True, true." Shel looked at his snake tattoo-the result of a bet he'd lost. "Webmind long ago beefed up the encryption on the signals from Caitlin Decter's eyePod," he said, "so I can't say for sure, but I'd put money on the little la.s.s from Texas."

Tony nodded. "No doubt. And I'm sure Webmind didn't like being cut in two."

"Speaking of Webmind," called out Todd Bertsch, one of the other a.n.a.lysts, from the back row, "I've just had a breakthrough, I think."

Tony sprinted up the sloping floor and stood behind Bertsch, who was in his early forties, with thinning brown hair and blue gray eyes. Bertsch had been a.s.signed to the task Colonel Hume had beseeched Tony to undertake: locate the missing hackers. "What have you got?"

"It's what they always say," Bertsch said, with a satisfied grin on his face. "Follow the money. Webmind bought a company called Zwerling Optics. The company was in Chapter 11, and they weren't likely to be coming out. He bought the whole building, contents and all, from the receiver."

"Webmind directly?"

"No. It was done through three intermediaries, but it was easy to trace back to him."

"You're sure it's him?" Tony asked.

Bertsch gave him a look.

"Sorry," Tony said. "Of course you're sure. What about the missing hackers?"

"At least some of them still have Internet access-coming from inside the Zwerling Optics building. They haven't posted anything, but I used the Bilodeau sieve and identified three of them with a high degree of certainty."

The Bilodeau sieve, developed by Marie Bilodeau of the RCMP, was based on a simple premise: the specific websites and blogs regularly accessed by a person are idiosyncratic to that person. Tony's own morning ritual included visiting Slate Slate and the and the Huffington Post Huffington Post-hardly an unusual combination-but also TrekMovie.com (the new film was shaping up to be (the new film was shaping up to be so so good!), good!), MobileRead.com (he had a fascination with ebook-reading hardware even though he preferred paper books), (he had a fascination with ebook-reading hardware even though he preferred paper books), Wired Wired's Threat Level blog, and the US weather forecast for Miami (which was where his parents had retired to), plus checking Twitter for the hashtags #nsa and #aquarium. Those eight things were enough to identify him even if he didn't log on or post anything of his own.

Bertsch was pointing at his monitor, which was showing the telltale list of URLs frequented by the hacker known as Chase-who, among other things, followed the part of Craigslist where antique computer equipment was bought and sold.

"So our hackers are alive and well," said Tony.

"Looks that way," Bertsch replied, showing him some additional Bilodeau IDs. "Webmind may have rounded them up, but at least some of them are still kicking."

"Doing what?"

Bertsch shrugged. "Can't say. They're not doing anything suspicious online-but as to what they're doing offline, your guess is as good as mine."

"Okay, good work," Tony said. "I'm going to go call Colonel Hume."

He went down the short white corridor to his office and punched out digits on his double-secured and scrambled phone.

"h.e.l.lo?" said the voice that answered on the second ring.

"Colonel Hume," said Tony. "Tony Moretti. We've located your hackers."

"Oh, G.o.d," said Hume. "All of them together?"

"We've identified at least three-Chase, Brandon Slovak, and Kinsen Ng-with a high degree of certainty."

"DNA? Or dental records?"

"Sorry to disappoint you, Colonel, but it's not a ma.s.s grave. They're alive in an office building in Takoma Park-a place called Zwerling Optics. We identified them by their distinctive web-usage patterns."

"Oh," said Hume, sounding surprised, then, a moment later: "What would you like to do now?"

"Well, the FBI's investigating, right?" said Tony. "We don't want to mess things up for them; obviously, we didn't have a warrant for this investigation, so us tipping them off directly could taint any convictions."

"You're suggesting due process for Webmind?" said Hume, sounding surprised.

"I'm suggesting we play by the rules except when we don't have to. Clearly, Webmind had to have human accomplices: that whole got-no-arms thing is a get-out-of-jail-free card for him otherwise when it comes to kidnapping charges."

"All right," said Hume. "I'll let the Bureau know. And, don't worry-I'll keep you out of it."

"I'm not sure you should be involved either, Colonel."

"Tony, you know as well as I do that I'm being watched. The White House hasn't cut me off yet because they don't want to; they're hedging their bets-giving the president plausible deniability while still letting me give them an option to take out Webmind."

Tony took a deep breath and let it out slowly. "All right," he said. "But be careful."

thirty-four.

On the evening of the school dance, Matt came to Caitlin's house to get her. In Ontario, as Caitlin had learned, a sixteen-year-old could get a G1 driver's license-but had to have another licensed driver in the car for the first year of driving. Matt could could drive, but he'd have to bring an adult along, so he and Caitlin walked to the dance. There was no breeze to speak of, and it felt like about forty-five degrees to Caitlin, and- drive, but he'd have to bring an adult along, so he and Caitlin walked to the dance. There was no breeze to speak of, and it felt like about forty-five degrees to Caitlin, and- No, she was in Canada now, and they (sensibly!) used the metric system here. She did the conversion instantly in her head: 45 minus 32 times 5 divided by 9; it was about seven degrees Celsius out. Much colder than it would be back in Texas, but people had a.s.sured her it wasn't bad for late October in Waterloo. Anyway, even though she had on a denim jacket, it gave her an excuse to squeeze closer to Matt.

Caitlin had only walked to the school once before: when Trevor Nordmann-the Hoser himself-had escorted her to the last school dance. Back then, she'd been blind: her first hints of vision hadn't occurred until later that evening, coming home alone through the pouring rain during a thunderstorm. All the other times she'd gone to the school, one of her parents had given her a lift.

It was turning out to be a pleasant walk: she was getting good at walking on unfamiliar terrain at a reasonable speed. At first, she'd felt uncomfortable trying to do so without her white cane, but she liked strolling along holding Matt's hand.

Howard Miller Secondary School had an impressive white portico in front of its entrance. Caitlin and Matt pa.s.sed through it and headed down the series of corridors that led to the main gymnasium.

Music blared from the speakers as they entered; Caitlin didn't recognize the song, but there were lots of Canadian groups she didn't know. The lighting was dim, and there were a couple of dozen people dancing-jumping about really; it was a fast song. At least as many people were standing around the edges of the room, some talking in small groups, others texting away. Sounds echoed off the hard walls and floor, and it was quite warm.

"Hey, Cait," said a voice she recognized.

She turned and smiled. "Hi, Sunshine!"

"Hi. Hey, Matt."

"Hi, Sunshine," he said, and Caitlin was pleased that he spoke up as he did so.

"Have you seen Mr. Heidegger?" Caitlin asked.

"He's around somewhere. He danced earlier with Mrs. Zehetoffer," Sunshine said, as if that were the funniest thing imaginable. "And-oh, there he is."

Sunshine pointed. Caitlin was good at drawing imaginary lines between fingertips and objects if she could see them both simultaneously, but she had to swing her head 180 degrees to see who Sunshine was pointing at, and she couldn't find the correct face in the crowd.

"I see him," said Matt. "Come on, Caitlin." And he led her over.

"Well, if it isn't my star pupil!" said Mr. H, grinning. He was skinnier than Matt and even taller than Caitlin's father.

Caitlin smiled. "Hi, Mr. H."

"Are you enjoying being a celebrity?" he asked.

"I figure my fifteen minutes are almost up," she replied, smiling.

"No doubt, no doubt. Still, everyone is very happy for you."

"Thanks," Caitlin said.

"And I gotta tell you, all the teachers here are talking about how your friend Webmind is going to affect education."

Caitlin tried to suppress a grin as the Braille for I expect an A for effort I expect an A for effort scrolled across her vision. "I guess he will, at that," she said. scrolled across her vision. "I guess he will, at that," she said.

Mr. H shook his head a bit. "People still don't get it," he said. "When I was your age, the first cheap pocket calculators appeared, and my my teachers were all arguing about whether we should be allowed to use them in cla.s.s. People kept saying, 'Yes, but what if they teachers were all arguing about whether we should be allowed to use them in cla.s.s. People kept saying, 'Yes, but what if they don't don't have one?' They kept trotting out silly desert-island or post-nuclear-holocaust scenarios. They just didn't see that the world had been irretrievably altered-that there'd never again be a time when memorizing multiplication tables would be have one?'

Webmind is like that: a permanent, irreversible modification of the human condition-and I think it's for the good."

Caitlin smiled, remembering all over again why she liked Mr. H so much. They chatted a few minutes more in the warm room, and then she and Matt drifted away. A slow dance soon started, and they headed into the center of the gym. She liked draping her arms around his neck and resting her head on his shoulder as they swayed with the music, even if, as always, the speakers were turned up so high that the sound was distorted.

When the song was done, Caitlin gave him a peck on the cheek, and said, "I've got to go to the girls' room."

Matt nodded. "Okay." He looked around the dim gymnasium, then pointed to the far wall, where there was an open door leading outside. "I'm going to get some fresh air; I'll meet you outside."

It was dark by the time Colonel Hume pulled up out front of Zwerling Optics, a four-story-tall office building with telecommunication dishes on the roof. According to tweets from ex-employees, as soon as the company had been bought, all sixty-seven workers had received generous severance payments and been escorted off the premises.

Of course, it was wrong to think of this building as Webmind's headquarters. He wasn't located here-and that was part of the problem. When Hume had co-auth.o.r.ed the Pandora protocol for DARPA in 2001, they'd been mostly worried about artificial intelligences that would be programmed in laboratories. Something like that would would have a physical location: a specific set of servers, a cl.u.s.ter of computers, likely in a single building that could be cordoned off or, if necessary, blown up. have a physical location: a specific set of servers, a cl.u.s.ter of computers, likely in a single building that could be cordoned off or, if necessary, blown up.

But Webmind was nowhere and everywhere everywhere-which meant, if Webmind was going to keep an eye on his sequestered hackers, there had to be video feeds out of this building. Fiber-optic trunks were hard to tap because the only way to do so was by physically cutting into the cable and diverting some of the photons, which resulted in a measurable drop in signal quality. But this building had coaxial cable leading out of it. And coax leaked leaked-you could read what was being sent along it without interfering at all with the datastream, and therefore without tipping anyone off about what you were doing. The ease of wiretapping coax was one of the reasons the US government kept quietly deflecting attempts to redo Internet infrastructure nationwide.

Hume was dressed in casual clothes: blue jeans and a sky blue cotton shirt with its sleeves rolled up revealing his freckled arms. He'd moved over to the front pa.s.senger seat so he'd have more room to work.

His laptop was open and perched on the dashboard above the glove compartment, and he was wearing silver headphones. The video feed he was intercepting was grainy, and it blacked out periodically; the sound was attenuated, as if it were coming from very far away.

The view he'd managed to tap seemed to be from a security webcam that endlessly panned left and right, taking about ten seconds to complete a sweep in each direction. The first person he spotted was a woman-white, straight brown hair that tumbled over her shoulders. Her face was bent down, intent on-yes, yes, on a keyboard-so he couldn't be positive, but he felt sure this was Simonne Coogan, the famed Drakkenfyre herself.

The camera continued to pan, and-G.o.d, there must be thirty-odd people in there! All were working at computers-some desktops, some laptops. A sound he'd first taken to be static was actually the combination of all their keystrokes.

The camera continued to move and- No question: the gaunt face, the dreadlocks, the glint off the gold ring through the right eyebrow: it was Chase. Something odd about his nose, though . . . ah, it was bandaged, and in one of society's countless acts of thoughtless humiliation, with a wide "flesh"-colored Caucasianbeige Band-Aid.

The camera panned on. More faces deep in concentration-but what the h.e.l.l were they all doing?

There was Devon Hawkins-Crowbar Alpha himself-wearing a Halo 4 T-shirt. Hume wanted to call Hawkins's mother, to put her mind at ease, but that would have to wait. Next to Hawkins was . . . hmmm. Might be Gordon Trent.

The camera's view was from the front of the room, so he couldn't see what was on any of the monitors. At the back of the room there was a long table covered with typical hacker sources of fuel: cans of beer and Red Bull, bottles of c.o.ke, an industrial coffee urn, and several Dunkin' Donuts cartons.

It didn't look like the hackers were prisoners, and yet it seemed likely that none of them had left this building for days. Records Tony Moretti had pa.s.sed him showed twenty-three food deliveries-mostly pizza, Chinese, and sushi-at all hours of the day and night.

The camera started to swing back in the other direction. Hume saw one of the people-a black man of maybe forty-get up and move over to stand behind a white guy in his late twenties; the former seemed to be giving the latter a hand with something.

And then Hume heard a deep male voice over the headphones-preternaturally calm but tripping ever so slightly over the gap between each word: "Attention, please, everyone." He recognized the voice, of course: it was the new, official Webmind voice-the one he'd introduced to the world with his speech at the UN. It went on: "Status reports, please. Transportation?"

"Ready," replied a man off camera.

"Information technology?" asked Webmind.

"Not yet-another half hour, tops."

"Housing?"

"Good to go," said a woman.

"Health?"

"Owned!" crowed a youthful male voice.

"Environmental Protection?"

The camera happened to catch this speaker, a long-haired white man: "I'm in-finally!"

"Justice?"

"Just a sec-yes, yes, I've got full control now."
