Zavala gazed in wonder at the smoldering ROV, its components scattered around the deck.

“I can see now why the video died,” Zavala said.

“That’s not the only thing that died,” Austin said.

He went over to the bodies lying on deck. He removed the mask from the man who had tried to kill Marla, revealing a cruel face with Asian features. The second man was Asian as well. Austin surveyed the deck, which was covered with cartridge shells. The smell of cordite hung in the smoke-filled air.

“Now we know why the B3 was attacked,” he said. “Doc Kane . . . We’ve got to talk to him.”

“Good luck!” Zavala said. “Doc made it pretty clear that his work was none of our business.”

Austin’s lips tightened in the smile that, in Zavala’s experience, had always presaged trouble.

“That’s too bad,” Austin said in an even tone. “Because I’m making it our business.”

SHANGHAI, CHINA

THE LICENSE PLATE ON THE SILVER MERCEDES S65 AMG sedan that emerged from the parking garage under Pyramid Trading Company’s fifty-story building displayed only the number 2, suggesting that the car’s owner enjoyed extreme wealth. Vanity plates were auctioned off for millions of dollars to affluent and superstitious bidders who believed that the low numbers would bring good luck.

To reinforce that good luck, the car’s skin was fashioned from rocketproof armor plate and its tinted-glass windows were bulletproof. The underside was fortified against street bombs. The six-hundred-horsepower V-12 engine under the hood could push the car’s speed up to two hundred miles an hour.

An armed guard wearing denim fatigues sat in the front seat next to the driver. For added security, the Mercedes was sandwiched between two four-hundred-ninety-three-horsepower Mercedes G55 AMG SUVs. Each SUV carried a driver and five guards armed with Chinese-made, lightweight Type 79 submachine guns that had firing capabilities of five hundred rounds per minute.

The three-vehicle motorcade followed a route that took it away from the high-rise apartment complexes and glitzy clubs around the Oriental Pearl Tower, the tallest building of its kind in the world. The car and its escorts sped along the banks of the Yangtze River, then turned off the highway and headed toward the destitute neighborhoods that are the embarrassing underside of the largest and wealthiest city in the People’s Republic of China.

The procession plunged deep into the warren of slums, entering a hellish landscape of a no-man’s-land that was so burned out and devoid of human life even the most desperate slum dwellers avoided it. The vehicles turned onto a narrow, unlit street and went through a gate, pulling up next to an abandoned brick warehouse. Weathered plywood covered the widows, broken glass and boards from packing crates littered the oil-soaked dirt parking lot, but the razor wire topping the electrified chain-link fence that gleamed in the headlights was brand-new.

The guards poured out of the SUVs and formed a cordon between the Mercedes sedan and a loading platform. The man riding shotgun in the sedan’s front seat got out and opened the rear door. The lone passenger emerged and walked briskly toward the platform, accompanied by his bodyguard. As the men climbed the platform stairs, a door on well-greased rollers slid silently open.

They entered the warehouse and the door slid shut. The illumination from fluorescent overhead lights revealed that the passenger from the Mercedes was a small man dressed in a medium blue suit that had been hand-tailored in London, a neatly knotted silk tie, and Testoni shoes that sold for two thousand dollars a pair. He had a rigid, almost military posture about him.

Silver hair, neatly parted on the left, and black-plastic-framed glasses gave Wen Lo an avuncular air of bland respectability more befitting a desk clerk in a three-star hotel than the head of a giant real-estate and financial consortium that was the cover for extensive prostitution, gambling, and drug operations on a global scale.

Wen Lo’s face was asymmetrical, not from left to right but from top to bottom. The lower part of his face featured plump cheeks and a boyish smile while the upper part had a wide forehead, heavy furrowing brows, and soulless jade-green eyes that showed no more emotion than an abacus.

Waiting inside the warehouse door were three men in blue-green hospital gowns and a pair of heavily armed guards wearing generic tan security uniforms. The hard-faced guards carried Tasers, sidearms, and clubs that hung from their wide leather belts.

A balding, weasel-faced man dressed as if for the operating room stepped forward.

“An honor to have you visit us, sir,” he said, giving a quick bow of the head.

Wen Lo responded with a barely perceptible nod.

“Tell me how your work is coming, Dr. Wu,” he said.

“We are making progress,” Wu said with cheerful optimism.

Although the lower part of Wen Lo’s face smiled, his eyes didn’t mirror the same pleasant expression.

“Please show me your progress, Dr. Wu.”

“I’d be glad to, sir.”

Wu led Wen Lo and his personal bodyguard through two sets of airtight chambers and along a short corridor that ended in a thick glass door. Responding to a gesture from Wu, a guard pressed an electrical switch that unlocked the door. Wu, Wen Lo, and the bodyguard stepped into a cellblock. Steel doors, solid except for small rectangular openings, enclosed a dozen cells.

As they walked between the cells, Dr. Wu said, “The men and women are segregated, four to a cell. We maintain full occupancy at all times.”

A few inmates pushed their faces close to the barred openings and called out to Wu and his guests to help them. Wen Lo, his face devoid of pity, turned to Wu.

“What is the source of these lab rats?” he asked.

Dr. Wu was rewarded handsomely enough for his work to afford a large apartment in a new high-rise overlooking the Yangtze and to keep his wife and his mistress clothed in the latest fashions, but he had convinced himself that his research was for the good of mankind. Although his work required that he suppress his humanity under a thin veneer of medical noninvolvement, the coldness of Wen Lo’s question stunned him. He was, after all, still a physician.

“As medical professionals, we prefer to call them subjects,” he said.

“Very well, Dr. Wu, I’m sure these subjects appreciate your professionalism. But you haven’t answered my question.”

“My apologies, sir,” Wu said. “This lab is surrounded by teeming slums, and it’s easy to lure the subjects in with promises of food and money. We choose only those in relatively good physical shape. People in the slums rarely report the missing, and the police never follow up.”

Wen Lo said, “Show me the next phase. I have seen prisons before.”

Wu escorted the two men out of the cellblock to a black-walled room. One wall was half glass, like the viewing area for a maternity ward. Visible through the glass were a number of full-sized beds, each occupied and enclosed in a transparent cylinder.

The occupants of the beds were quiet for the most part, but occasionally someone stirred restlessly under a tightly tucked sheet. Figures in white body-encasing protective suits moved like ghosts among the beds, checking electronic monitors and IV tubes.

“This is one of several sick rooms,” Wu said. “The subjects in each have been injected with the new pathogen and are proceeding through the stages of the virus. Although the virus is waterborne, it can be spread through contact as well. You can see by the way the technicians are dressed, and the separately vented enclosures for each subject, that we take every precaution to keep the disease contained to the rooms.”
