Extinction

The guy matched her pace. His shoes slapped the pathway. “Hey, slow down! Where you going?”

Layla started to run. Her father had once told her: If you can’t win a fight, there’s no shame in running away. She saw a lighted area ahead, a large rectangle of asphalt, and at its center was a lone man on inline skates. He was practicing his roller-dancing moves while listening to his iPod. The guy wore gym shorts and a basketball jersey, and luckily he was just as big as the guy who was chasing her. Layla sprinted toward the roller-dancer, waving her arms and yelling, “Hey! Hey!” to get his attention. The guy stopped dancing and removed one of his earphones.

“Yeah, what’s up?”

Then she heard a metallic click. The roller-dancer’s head jerked backward and he crumpled to the asphalt. Blood fountained from his scalp. In horror, Layla turned around and saw her pursuer approaching. He was Asian and dressed in a black suit, and he held a gun equipped with a silencer.

She ran in earnest now, charging down the gravel path next to Sheep Meadow. She was fast, a former star of her high-school track team, but the gunman was faster. He gained on her as she raced toward the Central Park Loop. The road had been closed to traffic hours ago, and no cyclists or dog-walkers or strolling couples were in sight. But another guy on inline skates was speeding down the Loop, a daredevil in spandex pants and a motorcycle helmet. Layla opened her mouth to call to him, but then she thought of what had happened to the guy in the basketball jersey. She was still agonizing over what to do when the skater went into a crouch and made a sudden turn. He barreled past her and smacked into the gunman. The tall Asian man tumbled backward and his gun went flying. Layla ran to the fallen man and kicked him in the head for good measure. He lay on his back, unconscious.

Meanwhile, the skater took off his helmet. He was also Asian. He wore a windbreaker over his spandex outfit and carried a backpack. “Layla Pierce?” His accent was thick. “I’m Wen Sheng.”

“Wen Sheng? I don’t know—”

“Yes, you know me. My code name is Dragon Fire.”

Oh shit, she thought. Her anonymous source. “I thought you were in China.”

He nodded. “I was. But the Guoanbu discovered what I did.” He pointed at the unconscious man on the ground. “They came after me. And they’re after you, too. They sent a team of agents to New York to find you. I’ve been shadowing them.”

Layla’s throat tightened. “They know about the backdoor?”

“Yes, and they know you downloaded the files. The documents about Tai He. Have you decrypted them yet?”

“Yeah, I just forwarded them to InfoLeaks for translation.”

He nodded again. “Good. Now I have two new files for you. I downloaded them before I left the Operations Center.” He took off his backpack, unzipped it and reached inside. “The documents are on the flash drive. And I have something else for you, a specimen.”

He pulled a small zippered pouch out of the backpack and handed it to her. Layla started to open it, but Dragon Fire stopped her. “No, not here. We have to leave.” Putting his hand on her back, he led her down the path, heading toward the park entrance on West Seventy-second Street. “I saw two other Guoanbu agents in the park. They’re not far.”

Layla reached for her phone. “I’ll call the police.”

“No!” Wen grabbed her cell phone and tossed it into the grass. “The American intelligence agencies are also looking for you. They’re scanning the communications bands.”

“But once we tell them—”

“Listen to me. The CIA and the Guoanbu are working together. You can’t trust any of the American authorities.”

“Wait, how do you know that?”

“I was also an agent with the Guoanbu. But no more. What they’re doing is wrong. You have to give the new files and the specimen to InfoLeaks, so the whole world can see them. Make sure—”

He stopped talking and stood absolutely still. Layla heard rapid footsteps. Two more men in black suits stepped onto the pathway behind them.

Dragon Fire pushed her toward West Seventy-second Street. “Go,” he whispered. “I’ll take care of them.”

“Hold on, what are you—”

“I said go!”

Confused, Layla ran west, clutching the pouch. Behind her she heard shouting in Mandarin. Then more metallic clicks, the sound of muffled gunshots.

She ran like mad until she reached the park entrance about a hundred yards away. Then she dared a look over her shoulder. Through the screen of trees, she saw the two men in black suits bending over Dragon Fire. He was sprawled on the pathway, motionless, his legs and arms akimbo.

She faced forward and kept running. Leaving the park, she raced down Seventy-second Street, dashing past the puzzled residents of the Upper West Side. She ran about half a mile, then flagged down a taxi going south on West End Avenue. She scanned the street from the backseat of the cab, looking in all directions, but no one seemed to be following her. She told the driver to go to Penn Station. She needed to get out of the city.

Once she caught her breath, she unzipped the pouch. It contained just two things, a flash drive and a specimen jar. Inside the jar was an odd-looking insect, about the size of a fly. Layla squinted at it, trying to get a better look. Protruding from the insect’s body, just under the thorax, was a tiny computer chip.

Supreme Harmony was conscious. It observed the world through twenty-nine pairs of eyes.

At the center of its world was the Analysis Room, a high-ceilinged, fluorescent-lit space, fifteen meters long and twelve meters wide. The room contained twenty-nine identical gurneys, arranged in six rows. To the left of each gurney was a cart holding a heart monitor and an EEG machine, and to the right was a steel pole supporting an intravenous line. And lying on each bed was a recumbent Module.

The Modules varied in size and appearance, but all were formerly human beings. They were linked by the implants in their eyes and brains, which constantly received and transmitted streams of wireless data. The wireless links enabled the Modules to work together, monitoring the surveillance video and sharing the results of their analyses. The network of Modules was also linked to the six computer terminals at the front of the room, which were connected to other computers operated by the Guoanbu, the Ministry of State Security. And those computers, in turn, were connected to the swarms.

Six human beings sat on chairs in front of the terminals. Every hour, three of the humans left their seats and attended to the intravenous lines, discarding the empty bags of fluid and replacing them with full ones. The humans wore white lab coats, and on the front of each coat were two Mandarin characters stitched in blue thread: TAI HE, Supreme Harmony. The Guoanbu had given this name to the network. It was also written on a sign above the computer terminals.

Until a few hours ago, the leader of the humans had been Dr. Zhang Jintao. He was the scientist who’d assembled the network for the Guoanbu and performed the implantations. First he put each Module into a comalike state by cutting into the thalamus, the organ that sustains consciousness by connecting the various parts of the brain. Severing those connections erased the Module’s individual consciousness but didn’t damage the brain’s processing centers. Then Dr. Zhang inserted the implants that linked the Module’s brain to the network. The implants delivered streams of surveillance video to the brain’s visual processing center and retrieved the results of the Module’s threat-detection analysis. By sharing their results and working in parallel, the network of comatose Modules could analyze the video far more efficiently than any group of ordinary human observers could.

During the early tests of Supreme Harmony, Dr. Zhang had realized that the health of the Modules would deteriorate if they never left their gurneys. So he learned how to activate the auditory and motor centers of their brains, which enabled the Modules to robotically follow simple vocal commands—sit, stand, lie down, walk. From
