"Consequently," Miss Pao said, "there were lapses in his Nanobar integument. An unknown number of tag mites passed through these openings and embedded themselves in his clothing and flesh. He discarded all of his clothing and scrubbed himself vigorously at a public shower before returning to his domicile, but three hundred and fifty tag mites remained in his flesh and were later extracted during the course of our examination. As usual, the tag mites were equipped with inertial navigation systems that recorded all of the suspect's subsequent movements."

The big cine feed was replaced by a map of the Leased Territories with the suspect's movements traced out with a red line. This boy did a lot of wandering about, even going into Shanghai on occasion, but he always came back to the same apartment.

"After a pattern was established, the tag mites automatically spored," Miss Pao said. The image of the barbed dart altered itself, the midsection– which contained a taped record of the dart's movements– breaking free and accelerating into the void.

"Several of the spores found their way to a sky-eye, where their contents were downloaded and their serial numbers checked against police records. It was determined that the suspect spent much of his time in a particular apartment. Surveillance was placed on that apartment. One of the residents clearly matched the suspect seen on the cine feed. The suspect was placed under arrest and additional tag mites found in his body, tending to support our suspicions."

"Oooh," Chang blurted, absently, as if he'd just remembered something important.

"What do we know about the victim?" Judge Fang said.

"The cine stat could track him only as far as the gates of New Atlantis," Miss Pao said. "His face was bloody and swollen, complicating identification. He had also been tagged, naturally– the tagger aerostat cannot make any distinction between victim and perpetrator– but no spores were received; we can assume that all of his tag mites were detected and destroyed by Atlantis/Shanghai's immune system."

At this point Miss Pao stopped talking and swiveled her eyes in the direction of Chang, who was standing quiescently with his hands clasped behind his back, staring down at the floor as if his thick neck had finally given way under the weight of his head. Miss Pao cleared her throat once, twice, three times, and suddenly Chang came awake. "Excuse me, Your Honor," he said, bowing to Judge Fang. He rummaged in a large plastic bag and withdrew a gentleman's top hat in poor condition. "This was found at the scene," he said, finally reverting to his native Shanghainese.

Judge Fang dropped his eyes to the tabletop and then looked up at Chang. Chang stepped forward and placed the hat carefully on the table, giving it a little nudge as if its position were not quite perfect. Judge Fang regarded it for a few moments, then withdrew his hands from the voluminous sleeves of his robe, picked it up, and flipped it over. The words JOHN PERCIVAL HACKWORTH were written in gold script on the hatband.

Judge Fang cast a significant look at Miss Pao, who shook her head. They had not yet contacted the victim. Neither had the victim contacted them, which was interesting; John Percival Hackworth must have something to hide. The neo-Victorians were smart; why did so many of them get mugged in the Leased Territories after an evening of brothel-crawling?

"You have recovered the stolen items?" Judge Fang said. Chang stepped to the table again and laid out a man's pocket watch. Then he stepped back, hands clasped behind him, bent his neck again, and watched his feet, which could not contain themselves from shuffling back and forth in tiny increments. Miss Pao was glaring at him.

"There was another item? A book, perhaps?" Judge Fang said. Chang cleared his throat nervously, suppressing the urge to hawk and spit– an activity Judge Fang had barred in his courtroom. He turned sideways and backed up one step, allowing Judge Fang to view one of the spectators: a young girl, perhaps four years old, sitting with her feet up on the chair so that her face was blocked by her knees. Judge Fang heard the sound of a page turning and realized that the girl was reading a book propped up on her thighs. She cocked her head this way and that, talking to the book in a tiny voice.

"I must humbly apologize to the Judge," Chang said in Shanghainese. "My resignation is hereby proffered."

Judge Fang took this with due gravity. "Why?"

"I was unable to wrest the evidence from the young one's grasp," Chang said.

"I have seen you kill adult men with your hands," Judge Fang reminded him. He had been raised speaking Cantonese, but could make himself understood to Chang by speaking a kind of butchered Mandarin.

"Age has not been kind," Chang said. He was thirty-six.

"The hour of noon has passed," said Judge Fang. "Let us go and get some Kentucky Fried Chicken."

"As you wish, Judge Fang," said Chang.

"As you wish, Judge Fang," said Miss Pao.

Judge Fang switched back to English. "Your case is very serious," he said to the boy. "We will go and consult the ancient authorities. You will remain here until we return."

"Yes, sir," said the defendant, abjectly terrified. This was not the abstract fear of a first-time delinquent; he was sweating and shaking. He had been caned before.

The House of the Venerable and Inscrutable Colonel was what they called it when they were speaking Chinese. Venerable because of his goatee, white as the dogwood blossom, a badge of unimpeachable credibility in Confucian eyes. Inscrutable because he had gone to his grave without divulging the Secret of the Eleven Herbs and Spices. It had been the first fast-food franchise established on the Bund, many decades earlier. Judge Fang had what amounted to a private table in the corner. He had once reduced Chang to a state of catalepsis by describing an avenue in Brooklyn that was lined with fried chicken establishments for miles, all of them ripoffs of Kentucky Fried Chicken. Miss Pao, who had grown up in Austin, Texas, was less easily impressed by these legends.

Word of their arrival preceded them; their bucket already rested upon the table. The small plastic cups of gravy, coleslaw, potatoes, and so on had been carefully arranged. As usual, the bucket was placed squarely in front of Chang's seat, for he would be responsible for consumption of most of it. They ate in silence for a few minutes, communicating through eye contact and other subtleties, then spent several minutes exchanging polite formal chatter.

"Something struck a chord in my memory," Judge Fang said, when the time was right to discuss business. "The name Tequila– the mother of the suspect and of the little girl."

"The name has come before our court twice before," Miss Pao said, and refreshed his memory of two previous cases: one, almost five years ago, in which this woman's lover had been executed, and the second, only a few months ago, a case quite similar to this one.

"Ah, yes," Judge Fang said, "I recall the second case. This boy and his friends beat a man severely. But nothing was stolen. He would not give a justification for his actions. I sentenced him to three strokes of the cane and released him."

"There is reason to suspect that the victim in that case had molested the boy's sister," Chang put in, "as he has a previous record of such accomplishments."

Judge Fang fished a drumstick out of the bucket, arranged it on his napkin, folded his hands, and sighed. "Does the boy have any filial relationships whatsoever?"

"None," said Miss Pao.

"Would anyone care to advise me?" Judge Fang frequently asked this question; he considered it his duty to teach his subordinates.

Miss Pao spoke, using just the right degree of cautiousness. "The Master says, 'The superior man bends his attention to what is radical. That being established, all practical courses naturally grow up. Filial piety and fraternal submission!– are they not the root of all benevolent actions?'
