"It was a large compound," Abayon said, remembering.

"Around 150 buildings covering several square kilometers. The Japanese used bubonic plague, cholera, anthrax, and other diseases in controlled tests on humans. They decided they also needed to make sure that the diseases worked the same on different races, so they began importing prisoners from other theaters of the war. That is how I ended up there.

"They did more than experiment – they also used the weapons. In their war against China, the Japanese used poison gas over one thousand times. They dropped bacteria from planes numerous times, starting plagues among not only enemy troops, but the civilian population. The estimates of how many died run into the hundreds of thousands."

"But…"

Abayon paused.

"Yes?"

"Biological warfare has never been considered particularly effective for the battlefield. That is why it has so rarely been used."

Abayon nodded.

"True. And it wasn't particularly effective then either. Even though they killed many, the Japanese couldn't control what they had unleashed. Japanese troops also died. But still, the experiments at 731 went on."

Abayon fell silent, and Fatima did not disturb him as his mind wandered down the dark alleys of his past. Finally he stirred.

"My wife. They took her before they took me. They called us meruta – logs. That's what they thought of us."

"Why logs?" Fatima asked.

"Because that's what we looked like when they stacked the bodies," Abayon said.

"Seventeen days after we arrived at Unit 731 – shipped there packed in trains like cattle – they took my love along with several dozen others. Out to the testing range. They tied them to stakes. A plane flew by overhead, spraying whatever latest germ the scientists had come up with.

"The lucky ones died quickly and on the stake. My wife wasn't one of the lucky ones. The Japanese doctors wanted to see how quickly the disease progressed and what it did to the victim. So at a certain schedule, soldiers garbed in protective gear would go out to the field of death and take a harvest. They would bring several living prisoners back to the doctors. Then…"

Abayon fell silent.

"Your wife was one of these chosen?" Fatima asked.

"Yes. I was in my barracks. Locked in. I could look through a split in the wood. I saw them drive the truck in, the bodies in the back, sealed in a protective tent. Still alive. The doctors wanted them alive. So they could cut them open and see what their diseases were doing to a living person.

"I heard my wife's screams. They went on and on. I had seen the bodies of others who had been taken into the operating lab before, so I had a good idea – too good – of what they were doing to her. Vivisection. Cutting her open without anesthesia. The screams became so bad, they couldn't even be recognized as coming from a human being anymore. It was like an animal that had been trapped and was being tormented."

Abayon spit.

"Doctor Ishii. Whatever oaths he had sworn in medical school were long forgotten. One hears so much about the Nazis and their death camps, but no one talks about 731. Everyone acts like it didn't exist. The Japanese premier and emperor both denied ever hearing of it at the end of the war. But Tojo personally gave Ishii a medal for his work there.

"And it was the Americans who would have paid the price if the Japanese had managed to make their weapons program effective. They planned to use balloon bombs to carry diseases to America. In 1945 they made a plan to use kamikaze pilots to dump plague-infected fleas on San Diego. There was another plan to send cattle plague in grain smut to affect the American economy. As the war wound down, Ishii came up with his most daring plan, which he named 'Cherry Blossoms at Night': use kamikaze pilots to hit the entire coast of California with plague. A sort of reverse of the Doolittle raid.

"Submarines were to take pilots and planes off the western coast of the United States. The submarines would surface and the planes would be launched. The date scheduled for this attack was September twenty-second, 1945. Fortunately for the Americans, the Japanese high command interceded and the submarines were diverted to be used against a closer threat: the American fleet at Ulith. All the Japanese managed to do was launch nine thousand incendiary bombs attached to balloons in the hopes that the jet stream would carry them across the ocean to America. They hoped to cause forest fires and terror. Several bombs made it, and one unfortunate woman was killed, but that was it."

"So 731 was a failure," Fatima said.

"For the Japanese," Abayon said.

"What do you mean?"

Abayon sighed.

"Let me finish my story and you judge for yourself. The war was coming to a close, but still Ishii ran his experiments. Then came my day. I was taken out to the field. Tied to a stake. To my right was the American, Martin. We waited, and then the plane came flying by, releasing something from the tanks under its wings. We knew we were dead men. Finally Martin told me his story.

"He had been recruited into the OSS – Office of Strategic Services – the American precursor to the CIA. He had been briefed that his team's mission was to parachute into Japan and make their way to a university where Japan's only cyclotron was located. It's a device that is needed to develop atomic weapons."

"But that wasn't their real mission," Fatima said, once more jumping a step ahead of the story.

Abayon nodded.

"Correct, it wasn't, as Martin found out, to his shock. They were picked up by the Kempetai on the drop zone, as if the Japanese were waiting for them and knew exactly when and where they would be jumping."

Abayon paused, then gestured.

"Could you get me some water?"

"That will take a while," Fatima said, knowing how far away the nearest room where she could fulfill his request was.

"We have time," Abayon said.

"Talking has made me parched. And I need a little time to collect my thoughts before I continue."

When Fatima left the observation point, Abayon checked his watch. It would begin soon. Very soon.

"Six minutes," the crew chief warned Vaughn.

Vaughn repeated the warning to Tai. They were standing next to the oxygen console. Vaughn made a twisting motion as he gave the next command.

"Go on personal oxygen."

They both unscrewed their oxygen hoses from the console and connected them to the small tanks strapped to their chests. Vaughn took a few breaths to make sure the tank was feeding properly. Everything was working perfectly so far.

"Depressurizing begun," the crew chief announced.

Both Vaughn and Tai swallowed as air began to leak out of the cargo bay so they could equalize with thin air outside at 25,000 feet.

The room was on the top floor of one of the tallest buildings in Hong Kong. To be allowed access, the half-dozen occupants had to suffer through a tedious two-hour security check. And these were not people who submitted easily to such checks. But the lure that had been dangled in front of them about what was to occur in this room at this late hour was more than enough to convince them to put aside their pride.

The half dozen were seated in comfortable chairs arranged in a semicircle facing a small stage with a podium on the right side. A curtain hid whatever was on the stage.

Ruiz stepped from behind the curtain and walked to the podium with a black three-ring binder in his hands. He set the binder down, then checked his watch.

"Gentlemen, and lady," he added, acknowledging the jewel-bedecked older woman seated in one of the chairs, "the first item will be up for bid in five minutes."
