This provided the first real setback in the investigation. The devices were picking up a lot of data, but it seemed (to make a long story short) that Abdallah Jones’s safe house was located directly above a nest of Chinese hackers whose gear radiated a huge amount of electronic noise into the ether. These hackers, as far as Olivia could make out, were the basketball players, who also seemed to do a lot of work on the building’s roof—so Jones’s nest was actually sandwiched between two levels of hacker activity. This made it difficult to tell Jones’s noise apart from the hackers’. So much so as to suggest that Jones might have chosen the site deliberately as a trick to hide his own emanations in his neighbors’ noise.
More stuff was FedExed, and Olivia made a foray into the apartment building and planted a device behind a radiator in the corridor just outside of Jones’s apartment. She was not privy to details, but she gathered that this somehow made it easier to sort out the terrorists’ bits from the hackers’ bits. Then MI6 flew in a signals intelligence boffin, using the name Alastair and pretending to be one of Xinyou Quality Control’s clients. Alastair and Olivia held lengthy “meetings” in the office, during which Alastair tweaked the equipment that was already there and installed a new box: a system for bouncing invisible lasers off the windowpanes of Apartment 505. Any sound inside the apartment would cause the windows to vibrate slightly, and the laser rig could pick up the vibrations and translate them back into surprisingly intelligible sound recordings. He also hooked up an automated video recording system that would turn on whenever movement was detected; that is, whenever the terrorists (for there was absolutely no doubt, now, that they were terrorists) opened a window.
The fact that the office building was under renovation provided huge advantages in using it as a surveillance platform. Its façade was obscured by a tangle of scaffolding, ropes, tarps, lashed bamboo, extension cords, work lights, and pneumatic hoses. Amid all that clutter, Alastair’s equipment—which was really quite modest in size—could easily go unnoticed. Their primary camera peered out through a hole, no larger than the tip of Olivia’s finger, in the blue tarp.
Olivia did not have to read any ecstatic memos from London to know that she had found a gold mine. What feedback she did get from London suggested that the value of the information they were getting was so high that they now wished that Abdallah Jones would pursue a very lengthy career of blowing things up, or preparing to, in Xiamen, just so that they could go on milking him. Reading the foreign newspapers, Olivia saw occasional reports of Predator drone strikes in Waziristan and could not help getting the impression that the stuff she was sending back to London was directly correlated with some of those.
She was running one of the most high-value installations in the global war on terror. And she was the only person who could run it. The operation was a colossal success—much more important than whatever now-forgotten job they’d originally wanted her to do. Euphoric as she might have been about this, at some level she knew that it couldn’t last. Eventually Jones would have to do something. He couldn’t just live there for month after month constructing bombs to no purpose. Sooner or later they would learn, from the lasers on the windows, that Jones was about to go blow something up. And then MI6 would have an interesting decision to make. If they did nothing, the explosion would happen and the PSB would investigate it and eventually find their way to Apartment 505. And working outward from there they would eventually come and check out Olivia’s office and find all the high-tech surveillance gear, arrest her, and subject her to God only knew what sort of treatment. If it came to that, Olivia would have to destroy the equipment and get out of town first.
Or, in a spirit of international cooperation, MI6 might tip off the Chinese authorities and thereby prevent Jones from carrying out his plan. But in so doing they would also tip their hand as to the sources and methods they’d used to learn all these interesting things, which would lead to the same or similar consequences for Olivia.
Or they could send in some kind of hit squad to kill Jones or even abduct him and get him out of the country. This, to put it mildly, would be a challenging operation.
In any case, Olivia had been supplied with detailed instructions as to how to shut down her little safe house, should it come to that. There were no papers to shred, no tapes to burn. Everything was electronic. So the shutdown procedure came down to frying the electronics. This they had made easy. Everything in the place had a kill switch; all she had to do was hit that, and a jolt of high voltage would go through all the chips and destroy the information stored in them. The PSB could still recover the circuit boards, but, according to Alastair, these were devoid of useful information; they were just stock chips, off-the-shelf stuff that anyone could buy from electronics retailers on the Internet, connected together in an obvious way. The important stuff—the unique stuff—was all in how they were configured, the bits that they contained, and this was easy to scramble. It would be nice, he stressed, if she could prevent the stuff from falling into their hands—for example, by throwing it over the railing of a ferry or burning down the building (she couldn’t tell whether he was being serious about this last suggestion)—but the most important thing was to hit all those kill switches.
In a properly manned safe house, there would have been at least three people, working in shifts, looking after the gear, always ready to hit the kill switches and shut the place down on a moment’s notice. A few decades earlier MI6 might have had the resources to maintain that many deep cover agents in China. If the operation had been in almost any country, they could have found a way. But in China it was just too difficult. Once Alastair had flown home, she was the only person there, and she could only spend so much time in the office. Meng Binrong sent her many pretend emails making him look like a total slavedriver, and this gave her the excuse she needed to clock twelve, fourteen, sometimes sixteen hours a day in the office, but sometimes she had to go back to Gulangyu and get a few hours’ sleep in her apartment, if only to keep up appearances with the landlord and the neighbors.
Because of those long hours and the tunnel vision that tended to set in as a result, perhaps she could be forgiven for being so oblivious, for so long, to the obvious target of Abdallah Jones’s preparations. Xiamen was hosting an international conference, bringing in diplomats from all over the globe. Ostensibly this was to celebrate the 350th anniversary of Zheng Chenggong’s liberation of Taiwan from the Dutch. But everyone knew that the real agenda was to discuss relations between Taiwan and mainland China and that very significant developments might be announced there. Some radical Islamists claimed Zheng Chenggong as one of their own, and accordingly considered Taiwan to be part of the Islamic Caliphate. It was a forlorn pretense, but anyway they were furious about oppression of Muslims in western China, so any excuse would suffice.
Olivia had noticed banners going up on lampposts, featuring heroic images of Zheng Chenggong, but did not really become aware that the conference was happening until it began to cause traffic jams on her way to work in the morning. At which point she understood, far too late, that there must be some connection between this and a recent spike in chatter from Apartment 505. The crisis must be nigh.
ONE MORNING SHE was returning to the office, having just enjoyed a few hours of sleep at home, when she noticed a minor oddity: a van parked on the street between the apartment building and her office. It was messing up the flow of traffic and creating a minor sensation among street vendors and passersby. If it hadn’t been for the diplomatic conference and her awareness that something big was about to happen, she might have ignored it. But as it was, her first thought was that the jig was up: it was a squad of PSB investigators come to knock on Abdallah Jones’s door and ask him what he and his friends were doing in there. Or worse: they were coming to arrest Olivia.
On further inspection, though, it didn’t look like an official vehicle, and the driver was a young woman in blue boots who seemed to be having some trouble with keys. But it had been enough to get h
er heart pounding, so after walking slowly and calmly into the office building and getting into the stairway where no one could see her, she ascended the steps two at a time and got into her office as soon as she could. Resisting the temptation to gawk out the window, she pulled on the headphones that she used to monitor the sounds in Abdallah Jones’s apartment.
Everything sounded routine: some snoring, a few sleepy men getting up and making tea, listening to an Arabic podcast. The very normality of this calmed her down quite a bit and made her feel a fool for having become so excited. She blotted perspiration from her forehead, sat down, set her purse on the desk, woke up her computer, and checked her email.
A huge thud came through on the headphones, followed by a great deal of excited talking.
Then some loud pops, clipped by the electronics so that they just came through as dropouts in the stream of noise.
Then the sound went dead entirely. She pulled off the headphones and realized that she could hear more pops directly from across the street. She went to the window and checked the laser device. It seemed to be in good repair. Then she peered through a peephole in the blue tarp and saw the problem: it worked by bouncing a laser off a windowpane. But the windowpane in question no longer existed.
She was startled by crashing and splintering noises from inside the office, just to her right. Pulling her head back inside, she noticed that half of her windows were now shards on the floor. There was dust in the air and craters in the wall opposite the windows. Her mind, slowly catching up, told her that she had just heard a long burst of automatic weapons fire and that a good bit of it had come directly across the street and sprayed the office.
She dropped to hands and knees, reached up, and hit the kill switch on the laser device.
MI6 had sent in a hit squad. They were doing it now. But they had forgotten to advise her.
Or perhaps they had just decided that she was expendable.
SOKOLOV HAD SEEN many strange things already this morning, and yet still he was taken aback when he swung out of the shattered window and scanned the front of the building to find it cluttered with young Chinese men crawling around on it like spiders.
Then he remembered that, sixty seconds earlier, his greatest concern in the world had been what to do about a cabal of Chinese hackers. These must be them.
He understood and approved of the decision that the hackers had made to avoid the building’s stairwells and escape via its exterior surface. It would have been easy enough to follow their lead down to the street, and in a sense this was the obvious decision to make, since they knew the terrain much better than he did. Often, in unfamiliar territory, it was wisest to pattern one’s movements after the locals’.
On the other hand, there was this thick bundle of wires running from a point on the building’s facade not far from where Sokolov was now, across the street to an office building under construction. The wires, in aggregate, must be a lot heavier than Sokolov, and so would probably support his weight. He favored the idea of using them as an escape route, for two reasons. First of all, simply getting down to the street might not help him that much, since, unlike the hackers, he could not blend in. He would be noticed and arrested very quickly. But if he could get into the other building he would have some chance of hiding somewhere, long enough, at least, to devise a plan.
Second, the apartment he had just left was full of high explosives and was on fire.
Now, compared to the typical layman, Sokolov was not especially worried about the proximity of ANFO and open flames. Like most high explosives, the stuff was difficult to set off. Fire alone would not suffice. Some sort of primer was needed: a detonator, such as a blasting cap. So it was quite possible that the entire building could burn to the ground without any sort of explosion taking place.
And yet this was a simplistic reading of the situation. There was a lot of other stuff in that apartment besides ANFO. During the few, frenzied moments he had spent there, Sokolov had not been able to make a systematic inventory. But if they were planning to use the ANFO, as seemed likely, then they must have some blasting caps in the place; and if they were planning to use it soon, then it was likely that they had already assembled some complete explosive devices in which the detonators had been mated with the ANFO. And anyway, in that devil’s kitchen he had just left behind, there was no telling what other stuff they might have mixed up: the terrorists had recipes for other explosives besides ANFO that were much less stable. And so there was a strong argument for getting away from the building as fast as he could. The wire bundle offered him that.
The main argument against it was that the terrorists could easily shoot at him as he was suspended in the air above the street right outside their windows.
But he could hand-over-hand his way along a stretched wire about as fast as most men could run. And the few terrorists who were still alive must be rather preoccupied. So that made the decision easy. He clambered over a series of window grates and other stuff to the wire bundle, reached out with one hand, grabbed, and slowly transferred his weight. The bundle didn’t rip loose from the wall. Good. He let go of the apartment building altogether, swung out into space, reached, and made another grab. Then another. Then another.
Then felt himself descending and saw the bundle receding into the sky.
This wasn’t like crossing a stretched steel cable in a military training camp. The bundle was a skein of perhaps two dozen separate wires, as gaily colored as a maypole. Some of the wires were electrical, some telephone, some data, some not clearly identifiable. He couldn’t get his hand around the whole bundle, and so every time he swung forward he had to thrust his fingertips like a blade into the heart of the thing and get a grip on whatever presented itself. This had worked the first few times, but on his last grab he had aimed wrong, missed the bundle, and snatched one single wire, a blue Ethernet cable that spiraled around all the other wires, and now his weight was pulling all the slack out of that one wire and peeling it loose from the bundle. He reached up with his free hand, whipped it around the taut blue line, and pulled himself up enough to get that first hand free, then repeated, ascending the wire but not gaining altitude since the blue wire was still giving up slack. He was only an arm’s length below the bundle but couldn’t quite reach it. Finally the wire stopped giving way and held fast and he kicked up with his legs, making himself upside down for a moment, and got both legs wrapped around the whole bundle. The rifle, and a CamelBak water pouch that he was wearing on his back, fell to the ends of their straps and dangled. He allowed himself a few seconds to catch his breath before he began shinnying along the bundle as rapidly as he could manage. This was much slower than the hand-over-hand technique and made him feel like an incompetent civilian, but he could not risk doing it the other way. In any case, he was not too worried about being shot at since the apartment was now completely engulfed in flames. Solvent cans burst open and vomited storms of combustible vapor from windows.
YUXIA WAS BEMUSED by the length of time it took the locksmith to work on the van’s ignition. Her family’s hotel in the mountains of Fujian was well stocked with DVDs of Western action movies, which could be had for next to nothing in Xiamen. From watching these, Yuxia had learned that any vehicle in the world could be started in a few seconds just by striking at the steering column until wires fell out and then touching the wires together until a spark was observed. And yet this locksmith turned it into an elaborate procedure that centered around picking the lock itself. It was quite obvious from the look on his face that he was extremely disturbed by all the gunfire taking place above, and that this was not making him get the job done any faster.
Yuxia was, of course, rather disturbed herself. She had reacted somewhat impulsively in handcuffing the poor locksmith to the steering wheel. At the time, only a few shots had been fired, and she had assumed that this would be the last of it, and that he would have the engine hot-wired in a few moments anyway. He was overreacting—using this as a pretext to abandon Yuxia,
and, by extension, Zula and Csongor and Peter. But since then it had developed into what sounded like a full-scale war, and pieces of debris kept clattering down onto the van’s roof. Every time it happened the locksmith was startled and seemed to lose his place in the lock-picking project. It dragged on for what seemed like a year, and Yuxia began to lose her nerve, as she felt both terrified to be in this predicament and guilty over what she had done to the locksmith. Nothing prevented her from exiting the van and running away. And yet every time she thought about it seriously, something big would slam down onto the van’s roof and remind her that it was a good thing to have steel over her head. And life really would be much easier for her if she could get this van out of here.
So preoccupied did she become with such thoughts that she was startled when she heard the van’s engine come to life. The dashboard lights came on and the tachometer needle rose off its pin.
The locksmith let out a curse, threw down the tools he’d been working with, and attacked the manacle with something else. This time it took him only a few seconds. Then he was gone, leaving the handcuff dangling from the steering wheel and half of his tools on the floor of the van. He didn’t bother to shut the passenger door.
Yuxia reached over, pulled the door shut, then settled herself in the driver’s seat again and put the vehicle into gear.
Then she took one last look back at the apartment building. What about Zula and her two hacker boys? The one who was bad for her, and the one who was good for her?
CSONGOR WAS A bit slower than Peter when it came to picking his handcuff. Zula noticed that he was sticking his tongue out as he worked. Somehow, from that, she concluded it was best to remain absolutely still and not distract him.
She, however, was growingly distracted by a sound that was echoing down the stairwell and getting louder every second. It was a human voice, repeating the same utterance, again and again, as if the speaker were an actor trying to memorize an elusive snatch of dialog. At the beginning she could only make out a few of the more percussive consonants, but as the speaker got closer, one flight at a time, she was able to piece the sounds together into words.
