"The tide does not negotiate with the sea wall; it merely measures where the stone was softest."
From The Folded Dawn: Collected Discourses, Sun Qiao, 2124
fell asleep in the ambulance somewhere on the Jinsha bridge, with her head on 's shoulder and a foil blanket round her, and he sat very still so as not to wake her.
Across from them Bo Han lay strapped to the stretcher with a medic leaning on his left shoulder, grey in the face, swearing in a steady, cheerful undertone whenever the van went over a joint in the road. sat at his feet with her knees drawn up. She was watching her own right hand. Every so often she turned it over, slowly, and watched the faint copy of it turn over a moment later, and turned it back.
Through the rear windows the sky over the estuary was going grey. At the base of 's throat, above the collar of the blanket, her mother's two small gold coins lay on their chain, and beside them, so faint now he could barely see it, the fern of scar tissue the rings had lit up in the dark.
She woke when the ambulance stopped. She looked first at , who looked away.
By mid-morning the salt water had drained out of the lower floor of Moonveil's headquarters and left a skin of grey silt on the marble. stood on the balcony above it and watched Coalition salvage crews in yellow slickers run cable into a computer vault that had spent three hours under the tide. Somewhere in that vault were Qiao's records, and he wanted them before anyone else did.
Across the canal a four-storey apartment block on Third Canal Road had split in two in the night. The whole upper half of the building had moved two point seven metres west and stopped there, resting on nothing, with a gap of daylight under one end where the floor below should have been. Survey drones circled it, painting the gap with green crossbars. Someone's washing was still on the line across a balcony.
came up the stairs from the street with silt to the knees. She had spent what was left of the night at the military hospital beside Bo Han's bed, and it showed only in the care she took on the steps.
"Bo?" said.
"They've stitched it again. He asked for soup." She looked at the apartment block. "Hoshino wants us."
Qiao's private suite had dark cedar walls and one low table of grey slate and a window looking south over the drowned docks to the sea. sat on a divan in the corner in a borrowed coat with her hands deep in its pockets. sat on the divan's arm, still in her torn stage silk, with her fringe over one eye. had her slate on the slate table and her thick black glasses pushed up into her hair, and she did not say good morning.
" Qiao's oldest files were in a navy code," she said. "Coalition Third Fleet. I couldn't open them until I used the key from your chips, Colonel."
did not move. "The Old Shenzhen logs." She had given those chips herself, out of her own classified records of the old city.
"Same secrecy level, same project number. The same people signed both." touched the glass. A wave came up in amber: the signal that had driven the chimeras through the streets last night. "That's the Parade. And this is a test record from the Third Fleet file, dated 2098." She dragged a second wave down over the first, a blue one, and it settled into the amber like a key into a lock. "They didn't invent it. Qiao never designed any of this machinery herself. Every signal she used was copied out of a wartime weapons programme. A weapon built to crush space itself. Thirty years old."
looked at the blue line. He had seen its shape before, at three in the morning in a drowned aquarium, laid over the three distress pings from 's suit on the Kepler. had seen it too. He watched her reach the same place a second after he did.
"," said. "The hive matched the Kepler. If the hive matches this..."
"Someone fired at it," said. "At the Halo, during the war. A metric compression warhead. They tried to squeeze it shut by force, by bending space as a weapon." He found he was looking at and not at the slate. "And whatever was inside it learned the geometry of the weapon."
looked back at him and said nothing at all, which was how he knew she had heard every word he had told her that night in the aquarium.
"Whatever was inside," repeated, slowly.
"Human debris," said from the divan.
They turned. She had not lifted her head.
"That's what you're all being too polite to call us. It's all right. I was sixteen," she said. "The intake scrubbers failed at the Central Redoubt shelter and I got grey lung. Pulverised masonry. I was in the pulmonary ward coughing up chalk, and she came in herself, smelling of clean linen, with a lacquered bowl of sliced pears." Her mouth moved. "She told me my lungs were fighting the wrong war. That the dust wasn't trying to suffocate me, it was only trying to settle. If I signed, they'd rebuild my chest with their cold light and I could dance again. Better than before. I'd never run out of air on a turn."
She lifted her hand and spread the fingers against the grey light from the window, and put it back on her knee. Half a second later a faint copy of the hand came down through the air after it and sank into the real one.
"I haven't taken an actual breath in eleven years," said. "I fake the heave of my ribs because strangers turn around and stare if you stand motionless in a crowd."
made no sound. Her shoulders came in.
"There's more," said, gently for her. " put the Circle's clinic routes out on the public radio last night. The routes match the clinics you funded, . All of them. Every free clinic in the southern wards for six seasons."
"I demanded them," said.
Her hands had come out of her pockets. The nails had gone into her palms and there were small dark beads of blood along the lines.
"Every contract renewal. I sat across the table from the board and from her and said, if you want my face thirty metres high on the harbour towers, you fund three treatment stations in every drowned precinct. Free nebulisers for the wet shelters. I thought I was bleeding their budget. I thought I was making them save people." She looked up at . Her eyes were dry and very bright. "They weren't clinics. Were they? They were sorting pens."
"Testing sites," said. She did not soften the word. "Children who'd lived through small ruptures in the shelters. They were logging which ones could stand the pull of a rupture without coming apart." She brought up one more image, a slow outline of a throat: collarbone, cartilage, the fine grey fern in the hollow above them. "And your scar shapes your low notes. That was in your file from the first scan. She spent sixteen years measuring how your voice moves a rupture."
"A tuning fork," said.
Nobody answered that. Out on the canal a diesel barge went under the pontoon bridge and the iron groaned.
"She's downstairs," said. Her voice had gone formal and cold. "The prosecutor. I saw them come in. Provincial constables, and two caskets on trolleys, the kind lined with lead. For me." She looked at . "I am not a witness, Colonel. I am evidence. Unlicensed biological anomaly built with restricted military hardware. Under the salvage decree I belong to whoever gets the paperwork signed first."
She turned to . The copy of her face arrived a fraction after the face.
"How long do I have, Doctor? Without her chip in my head?"
He had already worked it out, on the balcony, while he waited for . "Your index is zero point seven eight," he said. "It's falling at zero point zero two an hour." He saw she wanted it simpler. "About forty hours. Then you and that copy of you start to pull apart."
"So I go in the box," said .
"No," said .
She stood up. She came no higher than 's shoulder and her borrowed coat was black with canal mud to the knee, and she stood the way she had stood on the lotus stage with fifty chimeras round the pool.
"," said. "This is outside Boundary Operations. The Ministry of Justice has priority over hybrid material."
"She is not material." did not raise her voice. "She was sixteen and coughing up lime and they cut her open. If wants to put in a casket, she will have to put me in one first. Let the cameras on the canal film that. Moonveil's Voice, carried out in a lead box." She looked at and did not look away. "They'll take her to a laboratory in Nanjing and try to make more of her. You know they will, Colonel. You were made in one of their programs."
stopped breathing. watched 's face, and the small old scar through her eyebrow, and nothing in it moved for five seconds.
" is not Nanjing," said.
That was all, for a moment. Then: "She looks for crimes, not weapons. If is named a material witness and placed in protective military custody, the provincial bureau can't touch her without a Supreme Court order. That buys three months. Perhaps four."
"And the drift?" said to .
"Atlas-0 has a stabiliser built into its harness. It keeps the suit in step with the ground. can strip it down to something can wear. It won't cure anything, but it will keep her body and her copy together."
"A leash," said . Some of the edge had come back into her voice, and was glad to hear it. "Lovely. Do I get it in gold to match 's earrings?"
"Titanium-tungsten alloy," said, without looking up. "Mass of four hundred grams. And you will wear it, or I will personally bolt it through your collarbone."
The glass door slid back. stood in it with a leather case under her arm and river mud dried on one heel, and behind her in the corridor two constables waited at low ready.
"Colonel," she said. "General Zhao's liaison is at the south gate with a salvage commission and two caskets. He is asserting jurisdiction over every fractured asset in this building, including people. I have read his transit log back to him; he was forty-eight kilometres upriver when the sirens sounded." She set the case on the slate and opened it. "I have also told him that under Section Twelve salvage rights do not vest until a declaration of containment is countersigned by a civilian magistrate. No such declaration has been signed. Nor do I intend to affix my seal before Tuesday morning."
She lifted out a stack of warrants bound in red tape.
"Moonveil Media. The Helix Trust. Forty-six warrants: the directorate, the applied neurology division, the municipal liaison. Treason. Reckless endangerment of the city. Unlicensed modification of civilians. Homicide, for every death the Parade caused, as they are counted." She turned to . "Miss Kang. The state will need your testimony. Every allocation she put in front of you. Every page you signed in good faith."
"You'll have all of it," said. " stays with Unit Nine."
Ji-won looked at then: the torn silk, the hand on the knee, the copy that came after it.
"Miss is the only living witness to what was done in the Helix experiments," she said. "Moving her to a civil facility would be an unacceptable risk to the evidence. She will remain in the custody of Colonel until the preliminary hearings." She closed her case. "General Zhao believes he is about to take possession of Moonveil's primary storage. I would be grateful, Colonel, if my car could leave before he finds out the drives went to the base in Gu's armoured carrier an hour ago."
almost smiled. "They're already there."
When the prosecutor had gone, crossed the room to the divan. did not look up. Her shoulders were braced, the way you brace for a blow you have decided to take. reached down and took her left hand, the one with the ghost, and held it.
For a second or two the hands did not agree with each other. Then the faint copy flickered, narrowed, and settled down flat into 's wrist, and stayed there.
"Come on," said. "Let's go home."
looked at their hands for a long moment. Then she nodded, once, and got off the arm of the divan, and let herself be led out.
waited until their footsteps had gone down the corridor.
"Your model," she said. "Does it account for weapons residue?"
"No. It assumed space was old silk, tearing wherever it had worn thin." looked at the two traces still locked together on the slate. "We aren't looking for where the fabric is thin, Colonel. We're looking for the trajectory of the bullet."
was waiting at the top of the service stairs, which were the only way out of the suite that did not go past General Zhao.
He had his umbrella furled under one arm and grey mud on the hem of a coat that had certainly cost more than 's flat. He did not pretend it was a coincidence.
"Dr. Neumann. I'm glad you're whole."
"You told me in Ottawa," said, "that the Federation knew what happens to clocks when the Halo wakes up."
"I did say that." looked down the stairwell, at the silt on the treads. "We never gave Qiao the compression equations. I want you to know that, for what it's worth to you. But when the Helix Trust went looking for money after the war, certain offices in the Federation thought it prudent to let them run the experiments on foreign soil. We wanted the data. We wanted to see what the field would grow into when it met a living city." He said it in the same pleasant voice he had used in a service corridor in Ottawa. "We watched your Kepler logs, . We watched you map the scar."
"And you let them go on."
"Nobody on our side of the water had the nerve to touch the fire themselves." He tapped two gloved fingers on the brass rail. "Half an hour ago received the records of the Boston accounts that paid for it all. I thought she should have it before my office decides she shouldn't."
He went down the stairs into the grey light without looking back, and could not have said, then or later, whether he had just watched a man confess or a man make an investment.
The car park under the Judicial Office annex had flooded in the night and drained again, and the concrete was still wet and smelled of the river. Gu Yichen stood behind the third pillar from the ramp, guarding a meeting he did not like, and counted the exits. Two vehicle ramps, one stairwell, one goods lift that did not work. Fourteen cars. One of them was 's, black, engine running, rear door open, with the prosecutor standing in the angle of the door and her hand on the frame.
"He is four minutes late," she said.
"Actors," said Gu.
had telephoned her office at nine that evening from a public booth and asked for her by name. He had the paper ledgers, he said: the intake books from the clinic basements, with the children's names and the transfer chits, and his own signature on twenty-eight of them. He would bring them himself. He would not bring them to the front door.
At four minutes and forty seconds the stairwell door opened and he came through it alone, in a borrowed raincoat with the hood up and a bundle in plastic sheeting held against his chest with both arms. Under the hood his face was the face from the towers, and he looked very tired, and he walked straight toward the open car door.
Headlights came on at the top of the down ramp.
Gu had already moved. He was across the gap and had by the shoulder and had pulled him in behind the pillar before the van finished its turn, and he heard Ji-won say something sharp and short behind him. The van came down the ramp fast with its lights full on, and stopped broadside across the lane, and two men got out of the side door. One had a pistol with a long suppressor. The other had something short and fat in his hand that Gu did not like the look of.
"Behind me," Gu said. "Keep the books."
"They are rather the point," said. His voice was shaking and still perfectly pitched.
The first shot hit the pillar a hand's width from Gu's ear and threw concrete in his face. He kept his left arm across 's chest, pinning him flat to the column, and brought his sidearm round the edge with his right. Two men. Two lights. The headlights were the problem; they were looking into them and the men were not. He put a round through the left headlight and one through the right, and the lane went dark except for the van's interior light and Ji-won's car behind them, and in the sudden dark he could see the two men and they could not see him.
The man with the fat thing fired it. Gas, white, sweet-smelling, blooming off the pillar. coughed. Something tugged at Gu's sleeve and made a small surprised noise and folded against him.
Gu shot the man with the pistol twice, centre of mass, and he sat down against the van. The other one dropped the gas gun and ran up the ramp, and Gu let him go, because there was one of him and he had one person to count.
"."
"I think," said, quite conversationally, "that I have been shot in the arm." He was holding the bundle against his chest with the other arm. There was blood on the plastic. "I haven't dropped them."
"Good. Walk."
They walked, through the thinning gas, Gu's arm round him, to the open door of the black car, where had not moved one centimetre from her place in the angle of the door the whole time. She took the ledgers off first. Then she helped Gu get him onto the back seat.
"The north gate," she said to her driver. "Then the military hospital."
Gu got in the front. In the mirror had his head back against the seat and his eyes shut and his good hand flat on the ledgers, which Ji-won had put back on his knees because he had asked for them.
"One," Gu said, to nobody in particular, and the car went up the ramp into the rain.
It took three weeks to teach MECN-7 to look for what the old weapons had left behind, and the morning after he ran it, it gave them an address.
It was a single spot in the drowned district of Old Bao'an, where the sea had come over the dykes in the war and never left. Something there gave off a faint, steady trace, the kind a small machine makes when someone runs it on low power for a long time. took a boat and eight operators and , and they went in at first light, between the roofs of houses that stood in the sea to their second floors.
The building was an old teahouse with water lapping over its doorsill. went in first. heard her stop.
sat at a table on the dry upper landing, in the crane robe-coat, with a small brass ring on the floor beside her chair. It hummed quietly to itself, and the sea stopped at the bottom of her stair. A kettle was going on a camp stove. There were two cups on the table, and she had filled them both.
"Colonel," she said. "Dr. Neumann. I expected you on the tenth day. Your model is slower than its reputation." She lifted her cup. "May I finish?"
looked at her for a long moment. Then she stood back against the wall with her carbine lowered, and waited, and the operators on the stair waited behind her.
Qiao drank her tea without hurry. When the cup was empty she set it down, and stood, and held out her wrists. The bells on her braid made no sound as closed the cuffs. She went down the stairs between two operators into the boat, upright, and sat in the bow looking out over the flooded roofs at the grey sea, and did not look back at the teahouse, where the second cup stood full and cooling on the table.
