"The distinction between an echo and a casualty is strictly administrative. Where the body cannot be accounted for within three metres of its recorded coordinates, Coalition civil code allows six months before probate. The metric field requires no such patience."
From Directive 41-B Field Companion, Eastern Coalition Boundary Operations Command (2126)
The week the verdict came down, Unit Nine went into District Four to find what the Night Parade had left behind. The Binhai expressway had come down across the district on the night of the Parade, and nobody had found the money to lift it. It lay in two long slabs over the flooded street with its broken end in the air, and the morning sun came through the gap in shafts that stood on the water like posts. The water was knee-deep and perfectly still. Two streets north, where the clearance crews were working, a column of black smoke went straight up into a windless sky.
stood on the last dry kerb with his scanner in his hand and watched the numbers. Stability Index 0.41 on the street: worn thin, but holding. Under the expressway, where the old shelter clinic stood with its ground floor drowned to the window sills, the reading dropped and wandered.
"Two signatures inside," said. She was crouched on the kerb beside him with her field helmet pushed back and a scanner of her own balanced on her knee. "Three, maybe. Alive. Breathing. And something in there that makes my instrument think it is looking at an open furnace." She sounded pleased, and then caught herself sounding pleased, and frowned at the screen.
"Directive forty-one," Bo Han said. He was leaning on the expressway pillar with his rifle slung and his left arm stiff at his side, the old wound pulling at his collar. He said it the way you read out a ration list you did not like. "Anomalies showing integration with biological matter are to be neutralised and catalogued as biohazard residue."
"Incinerated," Gu said. He was down on one knee at the corner, watching the smoke. "The term they used over tactical was incinerated."
"It's tidy," said.
She had come up the street through the water without a splash. She carried no rifle, only the two compression batons strapped along her ribs, and her left forearm was still wrapped from wrist to elbow where the core had burned it. Her gauntlet was in pieces in 's workshop. had watched her look at the pieces, once, and walk away.
"Tidy reports let provincial ministers sleep," she said. "How far off is the crew?"
"Two blocks," Gu said. "They're doing one building every twenty minutes. Flatbeds with flame units on the back. They'll be here before ten."
"And the sluices?"
"Pier Nine opens at noon. This whole street goes under two metres by one o'clock."
came out of the doorway of a gutted noodle shop on the far side of the street. She had gone ahead before anyone could stop her, which was becoming a habit, and she walked back through the water toward them with her hands in the pockets of her black jacket. Her reflection on the still surface came after her a beat late, then caught up.
"They're in the old triage hall," she said. "Three of them. One is very loud."
"Loud how?" said. "To the ear, or to the instruments?"
"Both." Her grey eyes were too wide, the pupils almost swallowing them. "She's crying, Neumann. But her voice isn't coming out of her mouth. It's coming out of the light bulbs."
looked at her. "The ones the Circle let loose on the Parade were starved and drugged and driven at the crowd," said, before anyone could ask. "These ones hid. They went into the cellars and the clinics when the sirens started, because the sirens frightened them, and they have been sitting in there for a month waiting for the noise to stop." She took her hands out of her pockets. "You asked where they go when the signal stops, Colonel. They go home. That's the clinic most of them came out of."
Gu stood up. "Colonel. If Command finds out we went in ahead of the crew..."
"Then Command will need to know where we are," said. "Switch the BOC tactical channel to standby. Set our locators to show us on perimeter patrol. If they ask, District Four is full of rupture static and our video feeds are degraded."
Gu looked at her for a second longer than he needed to. "Understood."
"Bo Han, the door. Stun only. If anything comes at you, take its balance. Do not shoot to the core." She drew one of the batons and thumbed it awake. "Neumann, Hoshino, , behind me. Let's see what the Circle left."
The triage hall took up the whole ground floor. The flood had come in through the street doors and stopped at the height of the window sills, and the morning light came in above the water and lay across it in clean gold bars. Benches floated against the far wall in a row, the way they had been bolted. Paper intake forms had drifted together into a soft grey island in one corner. Along the ceiling a strip of emergency lights was still running on its battery loop, buzzing and flickering yellow.
The floor was wrong. felt it in the first three steps, the inner-ear lurch of a surface that sat lower than his eyes said it did. His scanner showed the ground here sagging, gently and steadily. It was the kind of weak spot that did not kill you. It only stayed.
"There," whispered.
Three figures were at the far end of the hall, where a cold-storage locker stood rusting against the wall.
One of them was part of the building. A boy, or what had been a boy, sat against an octagonal concrete pillar with his back fused into it. Below the ribs his body went into the concrete in pale ribbons of something like quartz, rooted forty centimetres into the column. His chest rose and fell very slowly, once every twenty seconds. The second was smaller, a teenager huddled in the water with his knees up, and his hands were shaking so fast that they had smeared into a violet blur three centimetres wide.
The third was a woman. She crouched in the water with her knees together, in what was left of a white nurse's tunic, and around her, fading outward like ripples, the water held three or four pale copies of her, each a little more transparent than the last and each a fraction of a second behind. From her left collarbone upward her body had folded into facets that bent the light like oil on water. Half her face was a woman's. The other half was cut crystal, and its eye was a well of black that took the beam of 's lamp and gave nothing back.
In her right hand, which was still an ordinary hand with chipped pink varnish on the nails, she held a ballpoint pen.
Click.
She was looking at the water between her knees. She did not look at the rifles.
Click.
"That's Xiao Rong," said. Her stage voice was gone. "Her name is Rong. She did intake at the flood shelter on Third Avenue. She always kept that exact ballpoint behind her left ear."
Bo Han put out a gloved hand and stopped her by a few centimetres of air. ". Look at the water round her knees. If she slips, that shoulder goes through an engine block."
"She won't slip." dropped her weight, the slow settling a dancer does before a long turn on a bad floor, and took her hands out of her pockets and let them hang open. "Xiao Rong."
The pen stopped mid-click.
Rong's head did not turn. It arrived. Her chin was down, and then her cheek was halfway round, and then the crystal side of her face was facing , with nothing in between. In the water the fading copies of her caught up one by one.
Above them the emergency strip buzzed and steadied, and a woman's voice came out of the lamp housing, thin and nasal and tired:
"...room four... please present your triage token at the pad... Dr. Gao is running seven minutes late... please take a seat on the benches..."
Her mouth did not move. could see her throat, and it was glass.
had come up on 's other side. She took off her helmet and set it down on a floating bench, and then she knelt, right down in the water up to her waist, and held out one bare hand with the palm up. "She is talking through the wiring," she said, very softly, to or to herself. She's looping the last week the shelter was open. The last thing that held its shape." She did not take her eyes off Rong. "You poor clever thing."
looked back once. Gu had his rifle at his shoulder. had her baton up and humming.
"Lower it," said, without turning round.
lowered it. After a moment Gu lowered the rifle.
"Xiao Rong," said, and went down on one knee beside in the water, two metres out. "The shift's over. The doors are locked. You don't have to take anyone else tonight."
The crystal along Rong's jaw shivered green and violet. The pen rattled against her thumb.
"...no cots left in ward C... there are mattresses along the corridor... please do not leave kettles near the main breaker..."
"Rong. It's Ke. Look at me." leaned into the light so her face was in it. Her eyes were wet and her mouth was perfectly steady. "Do you remember the red silk coat? With the brass frogging that split at the collar ten minutes before the New Year broadcast? You took two safety pins out of the supply cupboard and told me to hold my breath until the overture was over."
The thumb on the pen stopped.
The human eye, brown and bloodshot, opened wide. A single tear ran over the lid and cut a clean line through the dried silt on her cheek.
The voice in the lamp broke up, and came back smaller.
"...Ke? It's... it's so cold down here. I can't find the slip-on shoes I left under the desk. Ke, why does the floor keep sliding? Every time I put my heel down, the floor is gone."
moved forward through the water slowly enough not to make a wave and knelt on 's other side. From his inside pocket he took the passive stabilizer, a brass case the size of a pocket watch with a quartz plate under glass. He did not switch it on, because a powered field would hit her like a bar across a broken bone. He turned the side wheel until the plate inside began to sing at the pitch of the buzzing lamp, and then a little below it.
"It slides because the ground here has two different answers for what time it is," he said. "You aren't losing your mind, Rong. Your feet are looking for the floor as it was before the seam opened. That's all."
The crystal half of her face turned to him and broke his lamp into a hundred small lights.
"Who are you?" the lamp said.
"My name is . I teach physics. I know why the floor moves." He held up the brass case so she could see the glass. "I brought something you can lean against."
He set it on the floating bench beside her. Its dial came up a soft green, and the quartz plate inside rattled like a dry seed and then settled. The copies in the water around her drew in, closer and closer, until there were two, and then one. Her faceted arm sank a couple of centimetres and came to rest on her shins.
"They want to burn us," the lamp said. It sounded like a child talking through a wardrobe door. "The men in the grey coats. They have fire on the backs of their flatbeds. Long black nozzles. They said we weren't people anymore. They said the city had to be scrubbed."
Gu's collar unit squawked twice.
"Boundary Command to Unit Nine. We've lost your signal in District Four. Report status. Confirm neutralisation of the chimera cluster at the Third Avenue clinic."
Gu's glove went up to the throat mic and stopped a centimetre short. He looked at .
was looking at Rong's hand: the chipped pink varnish, the dirt under the nails, the cheap red-and-white pen.
"Tell them the ground floor was cleared," she said. "Tell them we found an unstable local collapse, used thermal suppression, and the biological material was consumed in the burn."
Gu did not press the switch. "Colonel. If they send a team in after us with proper scanners..."
"They won't find anything. The sluices open at noon. By one o'clock this floor is under two metres of sea, and by tomorrow it is mud."
Gu looked at the teenager with the shaking hands. He looked at the water. Then he pressed the switch.
"Unit Nine to Command. Third Avenue ground floor cleared. Target neutralised in a local collapse, thermal suppression deployed. Withdrawing south to the canal perimeter."
He let go of the switch and did not say anything else. Water dripped from a broken pipe somewhere over the door.
"Bo Han," said. "Where's the van?"
"Two blocks south, in the dry-dock tunnel under the bypass. The three-tonne diesel from the substation job. No markings." His neck had gone dark red above the collar.
"Gu, bring it round to the loading dock at the back. Hoshino, can you set the cargo coil to passive?"
"I can tune it to a quiet, steady note." was already pulling her slate out of its dry bag, still on her knees in the water. "It won't cure them. God, it won't undo anything the Circle did. But it will steady them, so the ground shifting under them doesn't tear at their nerves every time. They'll hurt less."
"They go to the quarantine ward at the old naval station in Shekou," said. "On Dr. Hoshino's research authority. Under my seal."
"That's outside your remit, Colonel." Gu said it to the doorway, where his eyes already were, checking the street. "The Military Council will have your insignia if they find live chimeras in an unlisted ward. They'll call it treason."
"Then let them have it." put the baton back in its sheath. "They gave me a brigade of eighteen-year-olds during the border collapses after the war and told me to hold the river with bayonets and diesel fuel. I did not let them throw those boys in a ditch to keep the map tidy, and I am not throwing a nurse with a ballpoint pen into an incinerator because Qiao decided to play god with a metric emitter."
She went forward through the water and held out her right hand, open.
"Rong. Can you walk?"
Rong looked at the glove for a long time. Her shoulder jumped once, three centimetres to the side and back. Then the human hand came out of the water, slowly, and closed round 's thumb.
"I have... I have my pen," said the lamp.
"Good."
lifted her in one movement, taking the weight onto her own shoulder before the broken side could grind. For a moment Rong's faceted arm went to violet smoke against 's chest, and then it was an arm again, with a wet click. did not flinch. She settled her and turned for the back door.
"Keep it," she said. "You might need to sign for your breakfast."
Bo Han waded past to the boy with the shaking hands and went down on one knee in front of him. He did not touch his rifle. When he spoke it was not in the clipped Mandarin of the unit but in the broad, round vowels of the Liaoning village he usually kept out of his voice.
"All right, little brother. Easy now. Just a truck ride, that's all. My uncle had an old Dongfeng tractor that rattled worse than this, I swear it."
He wrapped the boy in a foil blanket, three times round, and picked him up the way you lift a tray of unfired bowls. The boy's forehead went against Bo's vest. His hands kept shaking, scattering little points of violet light on the water, and then, slowly, they slowed.
The third figure had not moved.
went to the pillar and knelt in the water beside it and held up the scanner. It did not have to search. The Stability Index inside the boy's chest read zero. Exactly zero: 0.000. He looked up at the slow rise of the ribs and understood that the rise was the concrete settling.
"We can't move him," he said. "The rupture has grown him into the steel inside the pillar. If we pull, he'll break."
stood over them. Her eyes were dry.
"His name was Da-Wei," she said. "He was seventeen. When the shelter put on plays for the little ones after the June flood, he ran the battery soundboard behind the curtain. He liked the blue light cues best."
She bent and laid two bare fingers on the white stone of his temple. A spark the size of a match-head jumped between her fingertip and the stone and was gone.
"Wait for us, Da-Wei."
The loading dock opened onto a cut behind the clinic where the water was only ankle-deep. The van was already backed in, its rear doors open, and had climbed in to fit the cargo coil round Rong's neck. When it came on, a low steady note filled the cargo bay, and Rong's face stopped flickering at the edges and held still long enough for her to take a breath through her real mouth.
sat on the wheel arch beside her and did not let go of her hand.
stood on the step of the dock. To the north the smoke column had moved one building closer.
was a few paces away on the wet concrete with her arms crossed tight over her chest. In the dark glass of the van's side window her reflection uncrossed its arms a moment after she did, and then caught up.
"They're not errors, Neumann," she said. She did not look at him.
"I know."
" Qiao called them prototypes. She told me once, in the makeup chairs before the solstice gala, that the rupture wasn't breaking anything. It was clearing the table. She said if we didn't learn to breathe it now, we'd all go under when the real thing came down from the Moon." She said it flatly, the way she said everything that frightened her. "She believed it."
"I know that, too."
She reached out and took a pinch of his coat sleeve between her finger and thumb and pressed it hard, testing the wool.
"She knew my name," said. "Rong. With her brain coming out through the wiring and her voice coming out of a lamp. She looked straight at me and knew my name."
"A person is very difficult to erase completely," said. "Spacetime has a memory. It takes an enormous amount of work to make it forget who was there."
The corner of her mouth went up, the old Moonveil smirk, and did not get very far. "Go on, then, Professor. The Colonel's waiting for you to tell her which puddle won't drop her through the crust."
She swung up into the passenger seat and pulled the door shut. Gu came round the back, slammed the rear doors on and and the two shapes under their blankets, and climbed in behind the wheel. The engine turned over.
stood in the cut while the van pulled out through the water. Over the diesel, through the closed rear doors, he heard it once, small and clear.
Click.
By the start of the rains had been going to the District Four shelter on Thursdays for six weeks. It was nine flights down under the old metro, and the kitchen at the bottom fed anyone who came without asking for a ration chit: rice, a ladle of whatever the volunteers had stewed, radish pickled and cut by children. He ate at the end of the long table with the bound copy of his dissertation open beside the bowl. He had started on it the week of the verdict, in pencil. He was in chapter three.
sat down across from him with her own bowl. She ran the kitchen two nights a week now. Since the trial the receivers had frozen everything with her name on it, the recordings and the broadcast rights and the songs she had written at nineteen, and on the radio above the rice cooker a girl from Hangzhou was singing one of them anyway, a tone higher than had ever taken it.
"She goes flat in the bridge," said.
"You could sue her."
"I can't. I don't own it." She ate a slice of radish. "Neither does she. It's evidence." She turned his book round with one finger and read the page upside down. "What's this?"
"A coupling constant." He saw her face. "A number in the main equation. I made it up at twenty-four and wrote it down like a measurement."
"Is it wrong?"
"By a factor of eight."
"Does anyone still use it?"
"No."
"Then why are you fixing it?"
He did not have an answer that would not sound like a sermon. He wrote the corrected value in the margin, small, and initialled it, the way Dr. Chen had taught him to initial a change on someone else's draft. She watched him do it and said nothing, and when he looked up again she was reading the next page.
Afterwards she walked him up. She counted the stairs in Korean under her breath, the way she did in every building, so quietly that for weeks he had taken it for praying. When she lost her place she went back down to the last landing and began again; he had seen her do it twice. On the sixth flight a pump coughed and started in the wall beside them, and she stopped on the tread with her lips still moving.
waited for her to turn round.
She looked down at the landing, and up at the street light at the top of the shaft, and then she climbed on beside him without counting. Her hand stayed on the rail. Neither of them mentioned it.
At the street door the rain was coming down hard enough to bounce. She pulled her collar up.
"How many?" he said.
She thought about it. "I don't know." She frowned at the stairwell behind her, and then let it go. "Bring chapter four."
