Wounded Water #2
"Keep this arm warm. If he loses feeling, color or movement, find the naval medic."
The mother nodded too quickly.
"Thank you."
Marin looked at the fountain. Water ran normally now. She turned toward the corridor.
"Nobody closes another valve."
Kelm arrived, breathing hard. "I was about to enjoy that order."
"We isolate branches by breaking physical connections, not changing pressure inside them."
"Meaning?"
"Pipes."
He looked at her.
Marin pointed toward the ceiling. "Cut them."
The station spent the next twenty minutes dismantling its own plumbing.
Kelm found two engineers from the cutter squadron, both furious that the island's water system had become a tactical problem after they had already demolished a harbor lock.
Marin gave them no opportunity to defend the sequence.
She put one in the east crawlspace with a hacksaw and sent the other toward the laundry manifold with three customs officers and explicit instructions not to touch a valve.
They opened walls. They broke tile. They severed copper, lead and one antique ceramic conduit that Seraphine identified as older than the quarantine station and therefore, in Marin's opinion, overdue for disrespect. Each cut changed the behavior elsewhere.
When the laundry branch separated, water stopped crawling upward through the washhouse floor and fell normally for the first time since the blast. When the kitchen feed came free, three dry sinks began pouring for seven seconds and then stopped.
One pipe released seawater warm enough to steam despite the cold day outside.
Marin marked each response on the infirmary wall in chalk until the marks stopped describing rooms and began describing which pipes still shared water. A customs officer shouted from the west gallery that the surgical cistern had started reflecting a different ceiling.
Marin went there alone except for Kelm. Oliver tried to follow. She blocked the doorway with one hand.
"Sit down for five minutes."
"You continue to use that phrase as though it has legal authority."
"Your face has gone grey twice."
"Once was lighting."
"Five."
His eyes moved toward the west gallery, then to her left hand where the earlier injury had begun bleeding through the wrap again.
"Your hand."
"Five."
He exhaled through his nose.
"I dislike equal treatment."
"It wastes less time."
Oliver sat. Kelm waited until they were around the corner.
"You two always like this?"
"No."
"That's reassuring."
"Sometimes we are asleep."
The surgical cistern occupied a square room beneath the old operating theatre. Its surface lay behind an iron grate at floor level. The water should have reflected the stone vault above. Instead it showed open sky.
Grey clouds moved across it. Kelm stopped at the threshold.
"That sky is not ours."
Marin looked upward. Saint Orra's actual ceiling remained intact.
"Probably not."
"Probably?"
"I have learned to leave room for architecture behaving badly."
She crouched beside the grate. The reflection contained no sun, no birds and no recognizable coastline. Only clouds moving faster than the wind Marin could hear outside. She opened Perception and found the cistern connected to more than pipes.
Old Veinstone lay beneath it in a ring, a distribution working probably intended to keep stored water from carrying disease through the quarantine network rather than contain anything inside the cistern.
The outer-lock detonation had sent a pressure wave through the tideworks and cracked one segment of the ring.
The damaged working had tried to preserve continuity through every connected water source it could still recognize.
Someone had added another connection years later. Marin leaned closer and found a metal capsule beneath the grate near the cracked Veinstone, fixed to the stone with two modern screws.
Kelm followed her gaze. "Is that supposed to be there?"
"Ask the building."
"It has become unreliable."
"Then no."
The capsule had three fine copper whiskers touching different points of the old distribution ring. None carried enough current to influence the working, but all three held residue from whatever had passed through the Veinstone. Marin kept her hands off it.
"Get Venn. And an evidence case."
Kelm's expression hardened. "Hollowfang?"
"Get Venn."
He went. Marin stayed beside the cistern. The false sky moved under the grate. A drop of blood fell from her left hand and struck the stone beside it. She looked at the wrap. The injury was reopening from use, not magic. She preferred the honesty.
Footsteps returned. Venn entered first, followed by Kelm and a naval engineer carrying a padded metal case. Oliver came last. Marin looked at him.
"Five minutes."
"I am renowned for obedience in emergency medicine."
"You are renowned for lying attractively."
"Also true."
Venn crouched beside the grate. "What am I looking at?"
Marin pointed through the bars. "A later addition to the cistern ward. Modern screws. Three pickup contacts. No drive circuit I can see."
"Recorder?"
"Maybe."
Kelm looked at Oliver. "She hates that word from you."
"Only when I enjoy it."
Marin ignored both men.
"We remove the grate, not the device. If the connection changes when the grate moves, we stop."
The naval engineer unbolted one side. Nothing happened. The second bolt came free. The false sky rippled. Everyone stopped. Marin watched the cistern until the reflection settled again.
"Continue."
They lifted the grate straight upward. The device remained attached to the stone below. Marin used insulated forceps to examine the copper whiskers. Each ended against the old Veinstone ring with pressure contact rather than a soldered joint.
The pressure contacts could be lifted without cutting the original working. Marin raised the first and watched the false sky remain unchanged. The second did the same. When she lifted the third, the cistern water snapped back to Saint Orra's ceiling so abruptly that Kelm stepped backward.
Marin froze.
Venn said, "You said it wasn't driving the ward."
"I said I couldn't see a drive circuit."
"Difference?"
"Important one."
Marin waited until the water had remained ordinary for several breaths, then lowered the third contact toward the ring without touching it.
The surface darkened as the gap narrowed, and grey cloud returned beneath the water.
Marin pulled the contact away. Saint Orra's ceiling returned. Oliver had gone quiet.
"It isn't creating the instability," he said.
Marin looked at him.
He nodded toward the damaged Veinstone. "It's giving the damaged system another relationship to choose."
"Or recording through a sympathetic reference that becomes visible when the ward is unstable."
"Less romantic."
"More accurate."
She inspected the device housing. Five narrow marks surrounded a vertical line beneath one screw head. Kelm swore.
Venn's mouth hardened. "Hollowfang."
"Hollowfang-marked equipment," Marin said.
"You still need the distinction?"
"Until the equipment confesses."
Oliver smiled faintly. Marin removed the final contact and lifted the capsule into the padded case. The engineer sealed it.
"Now what?" Venn asked.
"Now we finish isolating the water system before someone decides evidence is a substitute for plumbing."
They returned to work. The western branch proved harder because the surgical cistern fed the lower seawater holding rooms through an old retrofit that had been revised so many times even Seraphine refused to defend it.
Marin found two undocumented crossfeeds, one blind loop and a brass pressure equalizer hidden behind a wall whose plaster looked newer than the pipe.
The Maw remained in the lower cistern under naval guard. Marin did not go near it. Venn wanted four officers kept below. Kelm wanted two of them reassigned to civilian water distribution. They began arguing beside the stair.
Marin cut across both.
"The Maw stays submerged with two guards and one medic. The other two carry sealed water uphill. If the lower cistern changes temperature, level or geometry, they leave the room and report it. They do not improvise."
Venn looked at her. "You are assigning my people now?"
"You can assign them differently after you produce a better plan."
Kelm smiled into his cup. Venn saw him.
"Do not encourage her."
"I lost that battle yesterday."
The lower branch was physically severed ten minutes later.
The effect moved through Saint Orra quietly.
A basin in the convalescent ward gave a small metallic cough and emptied.
The laundry floor dried from the edges inward.
The surgical cistern kept the proper ceiling.
Somewhere below, a pipe stopped hammering.
Marin stood in the central gallery and listened to ordinary water drain through ordinary metal. Her body relaxed before her mind permitted it. Kelm came up the stair with a list in his hand.
"All patients accounted for. Perrin has full movement in the arm. One broken ankle from the first surge, three lacerations, no missing civilians."
"Teren?"
"Which Teren?"
Marin frowned.
Kelm smiled. "You have collected too many people with the same name. The older fever patient from yesterday is uphill and furious about being evacuated before lunch."
"Acceptable."
"The station kitchen is dry. Also useless."
"Improvement can wait."
A customs runner came through the gallery carrying a sealed evidence case.
"Investigator. Lieutenant Commander wants you upstairs. The device opened."
Marin looked at Oliver. He had remained where she left him for nearly seven consecutive minutes.
"You may come."
"I treasure these promotions."
They used the old dispensary because it had no connected water fixtures after Kelm's engineers removed the sink from the wall with excessive satisfaction. The Hollowfang capsule lay open on folded cloth beneath two lamps.
Inside sat a clockwork drum, a narrow strip of treated paper and a Veinstone stylus mounted on a spring arm. The mechanism was simple enough to be insulting. Venn stood opposite it.
