"I know three of the names. All of them are famous scholars working at the forefront of physics research." w.a.n.g was a little distracted. His eyes locked onto the last name on the list. In his mind, the two characters took on a different tint than the names above it. How can her name appear here? What happened to her?

"You know her?" Shi pointed to the name with a thick finger, stained yellow from smoking. w.a.n.g did not reply. "Ha. Don't know her. But want to know her?"

Now w.a.n.g Miao understood why it made sense for General Chang to have asked to have this man who was once a soldier under his command. Shi, who appeared so vulgar and careless, had eyes as sharp as knives. Maybe he wasn't a good cop, but he was certainly a fearsome one.

A year earlier, w.a.n.g Miao had been in charge of the nanoscale components for the "Sinotron II" high-energy particle accelerator project. One afternoon, during a brief break at the Liangxiang construction site, w.a.n.g was struck by the scene before him. As a landscape photography enthusiast, w.a.n.g often saw the sights around him as artistic compositions.

The main component of the composition was the solenoid of the superconducting magnet they were still installing. About three stories high and only half completed, the magnet loomed like a monster made of giant blocks of metal and a confusing mess of cryogenic coolant pipes. Like a junk heap from the Industrial Revolution, the structure exuded inhuman technological grimness and steel-bound barbarity.

In front of this metal monster stood the slim figure of a young woman. The composition's lighting was fantastic as well: The metal monster was buried in the shadow of a temporary construction shelter, further emphasizing its stern, rough quality. But a single ray of light from the westering sun coming through the central hole in the shelter fell right on the woman. The soft glow lit up her supple hair and highlighted her white neck above the collar of her overalls, as though a single flower was blooming in a metal ruin after a violent thunderstorm....

"What are you looking at? Get back to work!"

w.a.n.g was shocked out of his reverie, but then realized that the director of the Nanotechnology Research Center wasn't talking to him, but to a young engineer who had also been staring at the woman. Having returned from art to reality, w.a.n.g saw that the young woman wasn't an ordinary worker-the chief engineer stood next to her, explaining something respectfully.

"Who is she?" w.a.n.g asked the director.

"You should know her," the director said, waving his hand around in a large circle. "The first experiment on this twenty-billion-yuan accelerator will probably be to test her superstring model. Now, seniority matters in theoretical physics, and normally, she wouldn't have been senior enough to get the first shot. But those older academics didn't dare to show up first, afraid that they might fail and lose face, so that's why she got the chance."

"What? Yang Dong is ... a woman?"

"Indeed," the director said. "We only found out when we finally met her two days ago."

The young engineer asked, "Does she have some psychological issue? Why else wouldn't she agree to be interviewed by the media? Maybe she's like Qian Zhongshu,11 who died without ever appearing on TV."

"But at least we knew Qian's gender. I bet Yang had some unusual experiences as a child. Maybe it made her somewhat autistic." w.a.n.g's words were tinged with a hint of self-mockery. He wasn't even famous enough for the media to be interested in him, let alone to turn down interview requests.

Yang walked over with the chief engineer. As they pa.s.sed, she smiled at w.a.n.g and the others, nodding lightly without saying anything. w.a.n.g remembered her limpid eyes.

That night, w.a.n.g sat in his study and admired the few landscape photographs, his works he was the most proud of, hanging on the wall. His eyes fell on a frontier scene: a desolate valley terminating in a snowcapped mountain. On the nearer end of the valley, half of a dead tree, eroded by the vicissitudes of many years, took up one-third of the picture. In his imagination, w.a.n.g placed the figure that lingered in his mind at the far end of the valley. Surprisingly, it made the entire scene come alive, as though the world in the photograph recognized that tiny figure and responded to it, as though the whole scene existed for her.

He then imagined her figure in each of his other photographs, sometimes pasting her two eyes into the empty sky over the landscapes. Those images also came alive, achieving a beauty that w.a.n.g had never imagined.

w.a.n.g had always thought that his photographs lacked some kind of soul. Now he understood that they were missing her.

"All the physicists on this list have committed suicide in the last two months," General Chang said.

w.a.n.g was thunderstruck. Gradually, his black-and-white landscapes faded into blankness in his mind. The photographs no longer had her figure in the foreground, and her eyes were wiped from the skies. Those worlds were all dead.

"When ... did this happen?" w.a.n.g asked mechanically.

"The last two months," Chang repeated.

"You mean the last name, don't you?" Shi responded with satisfaction. "She was the last to commit suicide-two nights ago, overdosed on sleeping pills. She died very peacefully. No pain."

For a moment, w.a.n.g was grateful to Shi.

"Why?" w.a.n.g asked. The dead scenes in those landscape photographs continued to flicker through his mind.

General Chang replied, "The only thing we can be sure of is this: The same reason drove all of them to suicide. But it's hard to articulate. Maybe it's impossible for us nonspecialists to even understand the reason. The doc.u.ment contains excerpts from their suicide notes. Everyone can examine them after the meeting."

w.a.n.g flipped through the notes: All of them seemed to be long essays.

"Dr. Ding, would you please show Yang Dong's note to Professor w.a.n.g? Hers is the shortest and possibly the most representative."

The man in question, Ding Yi, had been silent until now. After another pause, he finally took out a white envelope and handed it across the table to w.a.n.g.

Shi whispered, "He was Yang's boyfriend." w.a.n.g recalled that he had seen Ding at the particle accelerator construction site in Liangxiang. He was a theoretician who had became famous for his discovery of the macroatom while studying ball lightning.12 w.a.n.g took from the envelope a thin, irregularly shaped sheet exuding a faint fragrance-not paper, but birch bark. A single line of graceful characters was written on it: All the evidence points to a single conclusion: Physics has never existed, and will never exist. I know what I'm doing is irresponsible. But I have no choice.

There wasn't even a signature. She was gone.

"Physics ... does not exist?" w.a.n.g had no idea what to think.

General Chang closed the folder. "The file also contains some specific information related to the experimental results obtained after the completion of the world's three newest particle accelerators. It's very technical, and we won't be discussing it here. The first focus of our investigation is the Frontiers of Science. UNESCO designated 2005 the World Year of Physics, and that organization gradually developed out of the numerous academic conferences and exchanges that occurred among world physicists that year. Dr. Ding, since you're a theoretical physicist, can you give us more background on it?"

Ding nodded. "I have no direct connection with the Frontiers of Science, but it is famous in academia. Its core goal is a response to the following: Since the second half of the twentieth century, physics has gradually lost the concision and simplicity of its cla.s.sical theories. Modern theoretical models have become more and more complex, vague, and uncertain. Experimental verification has become more difficult as well. This is a sign that the forefront of physics research seems to be hitting a wall.

"Members of the Frontiers of Science want to attempt a new way of thinking. To put it simply, they want to use the methods of science to discover the limits of science, to try to find out if there is a limit to how deeply and precisely science can know nature-a boundary beyond which science cannot go. The development of modern physics seems to suggest that such a line has been touched."

"Very good," General Chang said. "According to our investigation, most of the scholars who committed suicide had some connection with the Frontiers of Science, and some were even members. But we've found no evidence of the use of illegal psychotropic drugs or techniques akin to the psychological manipulation of religious cults. In other words, even if the Frontiers of Science influenced them, it was only through legal academic exchanges. Professor w.a.n.g, since they recently contacted you, we'd like to ask you for some information."

Shi added gruffly, "Including the names of your contacts, the times and locations of meetings, the content of your conversations, and if you exchanged letters or e-mails-"

"Shut up, Da Shi!" General Chang said.

Another police officer leaned over and whispered to Shi, "Do you think we'll forget you have a mouth if you don't use it all the time?" Shi picked up his teacup, saw the drowned cigarette b.u.t.t inside, and put it back down.

Shi's questions irritated w.a.n.g again, not unlike the feeling a man has upon finding out that he has swallowed a fly with his meal. The grat.i.tude he had felt earlier was gone without a trace. But he restrained himself and answered, "My contact with the Frontiers of Science began with Shen Yufei. She's a j.a.panese physicist of Chinese descent who currently works for a j.a.panese company here in Beijing. She once worked at a Mitsubishi lab, researching nanotech. We met at a technical conference at the beginning of this year. Through her, I met a few other physicist friends, all members of the Frontiers of Science, some Chinese, some foreign. When I talked with them, all the topics were ... how do I put this? Very radical. They all involved the question that Dr. Ding just described: What is the limit of science?

"Initially, I didn't have much interest in these topics. I thought of them as only an idle pastime. My work is in applied research, and I don't know much about these theoretical matters. Mainly, I was interested in listening to their discussions and arguments. All of them were deep thinkers with novel points of view, and I felt that I was opening my mind through the exchanges. Gradually, I grew more interested. But all our talk was limited to pure theory and nothing else. They once invited me to join the Frontiers of Science. But if I had done so, attending the discussions would have turned into a duty. Since my time and energy were limited, I declined."

"Professor w.a.n.g," General Chang said, "we'd like you to accept the invitation and join the Frontiers of Science. This is the main reason we asked you here today. Through you, we'd like to learn more about the internal workings of the organization."

"You want me to be a mole?" w.a.n.g was uneasy.

"A mole!" Shi laughed.

Chang gave Shi a reprimanding look. He turned back to w.a.n.g. "We just want you to give us some information. We have no other way in."

w.a.n.g shook his head. "I'm sorry, General. I cannot do this."

"Professor w.a.n.g, the Frontiers of Science is made up of elite international scholars. Investigating it is an extremely complex and sensitive matter. For us, it's like walking across thin ice. Without someone from academia helping us, we cannot make any progress. This is why we're making this request. But we'll respect your wishes. If you won't agree, we understand."

"I am ... very busy at work. I just don't have the time."

General Chang nodded. "All right, Professor w.a.n.g, we won't waste any more of your time. Thank you for coming to this meeting."

w.a.n.g waited a few more seconds before realizing that he had been dismissed.

General Chang politely accompanied w.a.n.g to the door. They could hear Shi's loud voice behind them. "It's better this way. I disagree with the plan anyway. So many bookworms have already killed themselves. If we send him, he'd be a meat dumpling thrown to the dogs."

w.a.n.g turned around and walked back to Shi. Forcing his anger down, w.a.n.g said, "The way you speak is not appropriate for a good police officer."

"Who said I'm a good cop?"

"We don't know why these researchers killed themselves, but you shouldn't speak of them so contemptuously. Their minds have made irreplaceable contributions to humanity."

"You're saying they're better than me?" Still seated, Shi lifted his eyes to meet w.a.n.g's. "At least I wouldn't kill myself just because someone told me some bulls.h.i.t."

"You think I would?"

"I have to be concerned about your safety." That trademark smirk again.

"I think I would be much safer than you in such situations. You must know that a person's ability to discern the truth is directly proportional to his knowledge."

"I'm not sure about that. Take someone like you-"

"Be quiet, Da Shi!" General Chang said. "One more sentence and you're out of here!"

"It's okay," w.a.n.g said. "Let him speak." He turned to General Chang. "I've changed my mind. I will join the Frontiers of Science as you wish."

"Good!" Shi nodded vigorously. "Stay alert after you join. Gather intelligence whenever it's convenient. For example, glance at their computer screens, memorize e-mail or Web addresses-"

"That's enough! You misunderstand me. I don't want to be a spy. I just want to prove you're an idiot!"

"If you remain alive after you've joined them for a while, that would be the best proof. But I'm afraid for you..." Shi lifted his face, and the smirk turned into a wolfish grin.

"Of course I'll stay alive! But I never want to see you again."

They kept w.a.n.g out of the way while the others left so he wouldn't have to deal with Shi Qiang again. Then General Chang walked w.a.n.g all the way down the stairs and called for a car to take him back.

He said to w.a.n.g, "Don't worry about Shi Qiang. That's just his personality. He's actually a very experienced beat officer and ant.i.terrorism expert. Twenty years ago, he was a soldier in my company."

As they approached the car, Chang added, "Professor w.a.n.g, you must have many questions."

"What did everything you talked about in there have to do with the military?"

"War has everything to do with the army."

w.a.n.g looked around in the spring sun, baffled. "But where is this war? This is probably the most peaceful period in history."

Chang gave him an inscrutable smile. "You will know more soon. Everyone will know. Professor w.a.n.g, have you ever had anything happen to you that changed your life completely? Some event where afterward the world became a totally different place for you?"

"No."

"Then your life has been fortunate. The world is full of unpredictable factors, yet you have never faced a crisis."

w.a.n.g turned over the words in his mind, still not understanding. "I think that's true of most lives."

"Then most people have lived fortunately."

"But ... many generations have lived in this plain manner."

"All fortunate."

w.a.n.g laughed, shaking his head. "I have to confess that I'm not feeling very sharp today. Are you suggesting that-"

"Yes, the entire history of humankind has been fortunate. From the Stone Age till now, no real crisis has occurred. We've been very lucky. But if it's all luck, then it has to end one day. Let me tell you: It's ended. Prepare for the worst."

w.a.n.g wanted to ask more, but Chang shook his head and said good-bye, preventing any more questions.

After w.a.n.g got into the car, the driver asked for his address. w.a.n.g gave it and asked, "Oh, were you the one who took me here? I thought it was the same type of car."

"No, it wasn't me. I took Dr. Ding here."

w.a.n.g had a new idea. He asked the driver to take him to Ding's address instead.

5.

A Game of Pool As soon as he opened the door to Ding Yi's brand-new three-bedroom apartment, w.a.n.g smelled alcohol. Ding was lying on the sofa with the TV on, staring at the ceiling. The apartment was unfinished, with only a few pieces of furniture and little decoration, and the huge living room seemed very empty. The most eye-catching object was the pool table in the corner.

Ding didn't seem annoyed by w.a.n.g's unannounced visit. He was clearly in the mood to talk to someone.

"I bought the apartment about three months ago," Ding said. "Why did I buy it? Did I really think she was going to become interested in starting a family?" His laugh sounded drunk.

"You two..." w.a.n.g wanted to know the details of Yang Dong's life, but didn't know how to ask the questions.

"She was like a star, always so distant. Even the light she shone on me was always cold." Ding walked to one of the windows and looked up at the night sky.

w.a.n.g said nothing. All he wanted now was to hear her voice. But a year ago, as the sun sank in the west, when she and he had locked eyes for a moment, they had not spoken to each other. He had never heard her voice.

Ding waved his hand as though trying to flick something away. "Professor w.a.n.g, you were right. Don't get involved with the police or the military. They're all idiots. The deaths of those physicists had nothing to do with the Frontiers of Science. I've explained it to them many times, but I can't get them to understand."

"They seem to have conducted some independent investigation."
