"Why is she running?"

"Because an Angry Alligator Appeared," the book said, and panned back quite some distance to show an alligator, waddling along ridiculously, no threat to the fleet Nell. The alligator became frustrated and curled itself into a circle, which became a small letter.

"A is for Alligator. The Very Vast alligator Vainly Viewed Nell's Valiant Velocity." The little story went on to include an Excited Elf who was Nibbling Noisily on some Nuts. Then the picture of the Raven came back, with the letters beneath. "Raven. Can you spell raven, Nell?" A hand materialized on the page and pointed to the first letter.

"R," Nell said.

"Very good! You are a clever girl, Nell, and good with letters," the book said. "What is this letter?" and it pointed to the second one.

This one Nell had forgotten. But the book told her a story about an Ape named Albert.

A young hooligan before the court of Judge Fang;

the magistrate confers with his advisers;

Justice is served.

"The revolving chain of a nunchuk has a unique radar signature– reminiscent of that of a helicopter blade, but noisier," Miss Pao said, gazing up at Judge Fang over the half-lenses of her phenomenoscopic spectacles. Her eyes went out of focus, and she winced; she had been lost in some enhanced three-dimensional image, and the adjustment to dull reality was disorienting. "A cluster of such patterns was recognized by one of Shanghai P.D.'s sky-eyes at ten seconds after 2351 hours."

As Miss Pao worked her way through this summary, images appeared on the big sheet of mediatronic paper that Judge Fang had unrolled across his brocade tablecloth and held down with carved jade paperweights. At the moment, the image was a map of a Leased Territory called Enchantment, with one location, near the Causeway, highlighted. In the corner was another pane containing a standard picture of an anticrime sky-eye, which always looked, to Judge Fang, like an American football as redesigned by fetishists: glossy and black and studded.

Miss Pao continued, "The sky-eye dispatched a flight of eight smaller aerostats equipped with cine cameras." The kinky football was replaced by a picture of a teardrop-shaped craft, about the size of an almond, trailing a whip antenna, with an orifice at its nose protected by an incongruously beautiful iris. Judge Fang was not really looking; at least three-quarters of the cases that came before him commenced with a summary almost exactly like this one. It was a credit to Miss Pao's seriousness and diligence that she was able to tell each story afresh. It was a challenge to Judge Fang's professionalism for him to listen to each one in the same spirit.

"Converging on the scene," Miss Pao said, "they recorded activities."

The large map image on Judge Fang's scroll was replaced by a cine feed. The figures were far away, flocks of relatively dark pixels nudging their way across a rough gray background like starlings massing before a winter gale. They got bigger and more clearly defined as the aerostat flew closer to the action. A man was curled on the street with his arms wrapped around his head. The nunchuks had been put away by this point, and hands were busy going through the innumerable pockets that were to be found in a gentleman's suit. At this point the cine went into slow-mo. A watch flashed and oscillated hypnotically at the end of its gold chain. A silver fountain pen glowed like an ascending rocket and vanished into the folds of someone's mite-proof raiment. And then out came something else, harder to resolve: larger, mostly dark, white around the edge. A book, perhaps.

"Heuristic analysis of the cine feeds suggested a probable violent crime in progress," Miss Pao said.

Judge Fang valued Miss Pao's services for many reasons, but her deadpan delivery was especially precious to him.

"So the sky-eye dispatched another flight of aerostats, specialized for tagging." An image of a tagger stat appeared: smaller and narrower than the cinestats, reminiscent of a hornet with the wings stripped off. The nacelles containing the tiny air turbines, which gave such devices the power to propel themselves through the air, were prominent; it was built for speed.

"The suspected assailants adopted countermeasures," Miss Pao aaid, again using that deadpan tone. On the cine feed, the criminals were retreating. The cinestat followed them with a nice tracking shot. Judge Fang, who had watched thousands of hours of film of thugs departing from the scenes of their crimes, watched with a discriminating eye. Less sophisticated hoodlums would simply have run away in a panic, but this group was proceeding methodically, two to a bicycle, one person pedaling and steering while the other handled the countermeasures. Two of them were discharging fountains of material into the air from canisters on their bicycles' equipment racks, like fire extinguishers, waving the nozzles in all directions.

"Following a pattern that has become familiar to law enforcement," Miss Pao said, "they dispersed adhesive foam that clogged the intakes of the stats' air turbines, rendering them inoperative." The big mediatron had also taken to emitting tremendous flashes of light that caused Judge Fang to close his eyes and pinch the bridge of his nose. After a few of these, the cine feed went dead.

"Another suspect used strobe illumination to pick out the locations of the cinestats, then disabled them with pulses of laser light– evidently using a device, designed for this purpose, that has recently become widespread among the criminal element in the L.T."

The big mediatron cut back to a new camera angle on the original scene of the crime. Across the bottom of the scroll was a bar graph depicting the elapsed time since the start of the incident, and the practiced Judge Fang noted that it had jumped backward by a quarter of a minute or so; the narrative had split, and we were now seeing the other fork of the plot. This feed depicted a solitary gang member who was trying to climb aboard his bicycle even as his comrades were riding away on contrails of sticky foam. But the bike had been mangled somehow and would not function. The youth abandoned it and fled on foot.

Up in the corner, the small diagram of the tagging aerostat zoomed in to a high magnification, revealing some of the device's internal complications, so that it began to look less like a hornet and more like a cutaway view of a starship. Mounted in the nose was a device that spat out tiny darts drawn from an interior magazine. At first these were almost invisibly tiny, but as the view continued to zoom, the hull of the tagging aerostat grew until it resembled the gentle curve of a planet's horizon, and the darts became more clearly visible. They were hexagonal in crosssection, like pencil stubs. When they were shot out of the tag stat's nose, they sprouted cruel barbs at the nose and a simple empennage at the tail.

"The suspect had experienced a ballistic interlude earlier in the evening," Miss Pao said, "regrettably not filmed, and relieved himself of excess velocity by means of an ablative technique." Miss Pao was outdoing herself. Judge Fang raised an eyebrow at her, briefly hitting the pause button.

Chang, Judge Fang's other assistant, rotated his enormous, nearly spherical head in the direction of the defendant, who was looking very small as he stood before the court. Chang, in a characteristic gesture, reached up and rubbed the palm of his hand back over the short stubble that covered his head, as if he could not believe he had such a bad haircut. He opened his sleepy, slitlike eyes just a notch, and said to the defendant, "She say you have road rash."

The defendant, a pale asthmatic boy, had seemed too awed to be scared through most of this. Now the corners of his mouth twitched. Judge Fang noticed with approval that he controlled the impulse to smile.
