The anger he felt at his own cowardice suddenly overpowered his survival instinct. First he switched off the closed-circuit camera that would be used during the discussion, then he bent down and pulled off his shoes. Moving quickly, he stepped onto one of the chairs and stood in the middle of the table. Lawrence inserted the spider into a ceiling air-conditioning vent, made sure that the holding magnets were in contact with the metal, and jumped back onto the floor. Five seconds had gone by. Eight seconds. Ten seconds. Lawrence turned on the closed-circuit camera and began to adjust the chairs.

WHEN HE WAS growing up, Lawrence never suspected that his father was Sparrow, the Japanese Harlequin. His mother told him that she had gotten pregnant when she was a student at Tokyo University. Her wealthy lover refused to marry her and she didn’t want to have an abortion. Instead of bringing up an illegitimate child in Japanese society, she immigrated to America and raised her son in Cincinnati, Ohio. Lawrence accepted this story completely. Although his mother taught him to read and speak Japanese, he never felt the desire to fly to Tokyo and track down some selfish businessman who had abandoned a pregnant college girl.

Lawrence’s mother died of cancer during his third year of college. In an old pillowcase hidden in the closet, he found letters from her relatives in Japan. The friendly, affectionate letters surprised him. His mother had told him that her family had thrown her out of the house when she became pregnant. Lawrence wrote to the family members and his aunt Mayumi flew to America for the funeral.

After the ceremony, Mayumi stayed to help her nephew pack up everything in the house and transfer it to a storage warehouse. It was during this time that they found the belongings that Lawrence’s mother had brought from Japan: an antique kimono, some old college textbooks, and a photo album.

“That’s your grandmother,” Mayumi said, pointing to an old woman smiling at the camera. Lawrence turned the page. “And that’s your mother’s cousin. And her school friends. They were such pretty girls.”

Lawrence turned the page again and two photographs fell out. One showed his young mother sitting next to Sparrow. The other photograph showed Sparrow alone with the two swords.

“And who’s this?” Lawrence asked. The man in the photograph looked calm and very serious.

“Who is this person? Please tell me.” He stared at his aunt and she began to cry.

“It’s your father. I met him only once, with your mother, at a restaurant in Tokyo. He was a very strong man.”

Aunt Mayumi knew only a few things about the man in the photographs. He called himself Sparrow, but occasionally used the name Furukawa. Lawrence’s father was involved in something dangerous. Perhaps he was a spy. Many years ago, he was killed with a group of Yakuza gangsters during a gunfight at the Osaka Hotel.

After his aunt flew back to Japan, Lawrence spent all his free time on the Internet looking for information about his father. It was easy to find out about the Osaka Hotel incident. Articles about the massacre appeared in all the Japanese newspapers as well as the international press. Eighteen Yakuza had died. A gangster named Hiroshi Furukawa was listed as one of the dead, and a Japanese magazine printed a morgue photograph of his father. It seemed strange to Lawrence that none of the articles gave a definitive reason for the incident. Usually the reporter called it a “gangland dispute” or a “clash over illegal profits.” Two wounded Yakuza had survived, but they refused to answer questions.

At Duke University, Lawrence had learned how to write computer programs that could handle a large amount of statistical data. After graduation, he worked for a game Web site run by the U.S. Army that analyzed the responses of the teenagers who formed online teams and fought each other in a bombed-out city. Lawrence helped create a program that generated a psychological profile of each player. The computer-created profiles had a high correlation with the face-to-face evaluations performed by the army’s recruiters. The program determined who was a future master sergeant, who should operate the radio, and who would volunteer for high-risk missions.

The army job led to a job in the White House and Kennard Nash. The general felt that Lawrence was a good administrator and that he shouldn’t waste his talents writing computer programs. Nash had a relationship with the CIA and the National Security Agency. Lawrence realized that working for Nash would help him obtain a high-level security rating that would give him access to secret data about his father. He had studied the photograph of his father with the two swords. Sparrow didn’t have the elaborate tattoos of a typical Yakuza.

Eventually General Nash called Lawrence into his office and gave him what the Brethren called “the Knowledge.” He was told the most basic version: that there was a terrorist group called the Harlequins who protected heretics called Travelers. For the health of society, it was important to destroy the Harlequins and control the visionaries. Lawrence went back to his workstation with his first Brethren access codes, typed his father’s name into the information database, and received his revelation. NAME: Sparrow. AKA: Hiroshi Furukawa. SUMMARY: Known Japanese Harlequin. RESOURCES: Level 2. EFFECTIVENESS: Level 1. CURRENT STATUS: Terminated-Osaka Hotel-1975.

As Lawrence was given more of the Knowledge and a larger range of access codes, he discovered that most of the Harlequins had been destroyed by Brethren mercenaries. Now he was working for the forces that had murdered his father. The evil surrounded him, but like a Noh actor he kept his mask on at all times.

When Kennard Nash left the White House, Lawrence followed him to a new job at the Evergreen Foundation. He was allowed to read the Green, Red, and Blue books that described the Travelers and Harlequins and that gave a short history of the Brethren. In this new age, the Brethren rejected the brutal totalitarian control of Stalin and Hitler for the more sophisticated Panopticon system developed by the eighteenth-century British philosopher Jeremy Bentham.

“You don’t need to watch everyone if everyone believes they’re being watched,” Nash explained. “Punishment isn’t necessary, but the inevitability of punishment has to be programmed into the brain.”

Bentham had believed that the soul didn’t exist and there was no reality other than the physical world. Upon his death, he promised to leave his fortune to the University of London if his body was preserved, dressed in his favorite clothes, and placed in a glass case. The philosopher’s body was a private shrine for the Brethren, and they all made a point to see it whenever they were visiting London.

A year ago, Lawrence had flown to Amsterdam for a meeting with one of the Brethren’s Internet monitoring teams. He had a one-day layover in London and took a taxi to the University College London. Entering from Gower Street, he walked across the main quadrangle. It was late in the summer and quite warm. Students wearing shorts and T-shirts were sitting on the white marble steps of the Wilkins Building and Lawrence felt jealous of their casual freedom.

Bentham sat on a chair inside a glass-and-wood display case at the entrance to the south cloister. His skeleton had been stripped of flesh, padded with straw and cotton wool, and then dressed in the philosopher’s clothes. The philosopher’s head had been kept in a container placed at his feet, but students had stolen it for football games on the quadrangle. Now the head was gone, stored in the university’s vault. A wax face had been substituted, and it had a pale, ghostly appearance.
