Lawrence Takawa was ready to jump up and drive back to the center. He controlled his emotions and switched off his computer. When Kennard Nash first told him about the Virtual Panopticon, it was just a philosophical theory, but now he actually lived inside the invisible prison. After one or two generations, every citizen in the industrial world would have to make the same assumption: that they were being tracked and monitored by the Vast Machine.

I’m alone, Lawrence thought. Yes. Completely alone. But he assumed a new mask that made him look alert, diligent, and ready to obey.

Sometimes Dr. Richardson felt like his old life had completely disappeared. He dreamed of his return to New Haven like a ghost from Dickens’s A Christmas Carol, standing on the street in the cold darkness while his former friends and colleagues were inside his own house laughing and drinking wine.

It was clear that he never should have agreed to live at the research compound in Westchester County. He thought it would take weeks to arrange his departure from Yale, but the Evergreen Foundation appeared to wield extraordinary power at the university. The dean of the Yale Medical School had personally agreed to Richardson’s sabbatical at full salary, and then asked if the foundation might be interested in funding the new genetic research lab. Lawrence Takawa hired a Columbia University neurologist who agreed to drive up every Tuesday and Thursday to finish teaching Richardson’s classes. Five days after his interview with General Nash, two security men showed up at Richardson’s house, helped him pack, and drove him to the compound.

His new world was comfortable, but very restricted. Lawrence Takawa had given Dr. Richardson a clip-on Protective Link ID, and this determined his access to the different parts of the facility. Richardson could enter the library and the administrative center, but he was denied access to the computer area, the genetic research center, and the windowless building called the Tomb.

During his first week at the facility, he worked in the library basement practicing his surgical skills on the brains of dogs and chimpanzees as well as a fat cadaver with a white beard that the staff called Kris Kringle. Now that the Teflon-coated wires had been successfully inserted in Michael Corrigan’s brain, Richardson spent most of his time in his small apartment at the administrative center or in a cubicle at the library.

The Green Book gave a summary of the extensive neurological research performed on Travelers. None of the reports had been published, and thick black lines disguised the names of the various research teams. The Chinese scientists had apparently used torture on Tibetan Travelers; the footnotes described chemical and electric-shock treatments. If a Traveler died during a torture session a discreet asterisk would be placed beside the case number of the subject.

Dr. Richardson felt like he understood the key aspects of a Traveler’s brain activity. The nervous system produced a mild electric charge. When the Traveler was going into a trance state, the charge became stronger and showed a distinctive pulsing pattern. Suddenly everything seemed to switch off in the cerebrum. Respiration and cardiovascular activity was minimal. Except for a low-level response in the medulla oblongata, the patient was technically brain-dead. During this time, the Traveler’s neurological energy was in another realm.

Most Travelers showed a genetic link to a parent or relative who had the power, but this wasn’t always true. A Traveler could appear in the middle of rural China, born to a peasant family that had never traveled to another realm. A research team at the University of Utah was currently preparing a secret genealogy database involving all known Travelers and their ancestors.

Dr. Richardson wasn’t sure what information was restricted and what could be shared with the rest of the staff. His anesthesiologist, Dr. Lau, and the surgical nurse, Miss Yang, had been flown in from Taiwan for the experiment. When the three of them ate together at the cafeteria, they talked about practical matters or Miss Yang’s passion for old-fashioned American musicals.

Richardson didn’t want to discuss The Sound of Music or Oklahoma. He was worried about the possible failure of the experiment. There was no Pathfinder to guide Michael, and his team hadn’t received any special drugs that would force the Traveler’s Light out of his body. The neurologist sent a general e-mail asking for help from other research teams working at the facility. Twelve hours later, he received a lab report from the genetic research building.

The report described an experiment involving cell regeneration. Richardson had studied the concept many years ago in his undergraduate biology class. He and his lab partner had cut a flatworm into twelve different pieces. A few weeks later, there were twelve identical versions of the original creature. Certain amphibians, such as salamanders, could lose a leg and grow a new one. The Research Project Agency of the United States Defense Department had spent millions of dollars on regeneration experiments with mammals. The Defense Department said it wanted to grow new fingers and arms for injured veterans, but there were rumors of more ambitious attempts at regeneration. One government scientist told a congressional panel that the future American soldier would be able to sustain a major bullet wound, heal himself, and continue fighting.

Apparently the Evergreen Foundation had gone far beyond that initial research in regeneration. The lab report described how a hybrid animal called a “splicer” could stop bleeding from a serious wound in one to two minutes and could regenerate a severed spinal nerve in less than a week. How these scientists had achieved these results was never described. Richardson was reading the report a second time when Lawrence Takawa appeared in the library.

“I just found out that you received some unauthorized information from our genetic research team.”

“I’m glad it happened,” Richardson said. “This data is very promising. Who’s in charge of the program?”

Instead of responding, Lawrence took out his cell phone and dialed a number. “Could you send someone over to the library,” he said. “Thank you.”

“What’s going on?”

“The Evergreen Foundation isn’t ready to publish its discoveries. If you mention the report to anyone, Mr. Boone will see it as a security violation.”

A security guard entered the library and Richardson felt sick to his stomach. Lawrence stood beside the cubicle with a bland expression on his face.

“Dr. Richardson needs to replace his computer,” Lawrence announced as if there had been some kind of equipment failure. The guard immediately disconnected the computer, picked it up, and carried the machine out of the library. Lawrence glanced at his watch. “It’s almost one o’clock, Doctor. Why don’t you go have lunch.”

Richardson ordered a chicken salad sandwich and a cup of barley soup, but he was too tense to finish the meal. When he returned to the library, a new computer had been placed in his cubicle. The lab report wasn’t on the new hard disk, but the foundation’s computer staff had downloaded a sophisticated chess simulator. The neurologist tried not to think of negative consequences, but it was difficult to control his thoughts. He nervously played endgames for the rest of the day.

ONE NIGHT AFTER dinner Richardson remained in the employee cafeteria. He tried to read a New York Times article about something called the New Spirituality while a group of young computer programmers sat at a nearby table and made loud jokes about a pornographic video game.
