Wounded Water #3
"No transmitter."
"I prefer that," Marin said.
"You sound disappointed."
"I dislike convenient answers."
The naval engineer turned the drum with tweezers. A line emerged across the paper. For most of its length, the trace barely moved. Small regular rises corresponded roughly to tides and routine pressure cycles. Then came a hard vertical spike.
Beside it, a mechanical timestamp. Kelm read it first.
"Outer lock."
Marin checked the station clock. The mark fell within less than a minute of the naval demolition. Everything after it became irregular, with large oscillations, clipped peaks and one broad region where the stylus had torn the treated surface.
The engineer continued unwinding. Stamped text appeared beneath the trace.
EXTERNAL LOAD EVENT.
A few inches later:
NETWORK DISAGREEMENT ABOVE THRESHOLD.
Oliver leaned closer without touching the table.
"That's a charming phrase."
"It is a measurement label," Marin said.
"Those are often where institutions hide their poetry."
She ignored him and kept reading. Near the end of the strip, a second line began beneath the first. It remained flat until the water system destabilized, then climbed in short stepped increments.
REFERENCE ACCEPTANCE.
Marin went still.
Venn noticed. "Meaning?"
"Unknown."
"You have a theory."
"Several."
Kelm looked toward the sealed capsule. "Did it cause what happened?"
Marin put both hands on the table and reconstructed the morning in order.
Naval engineers had destroyed the outer lock to deny an armed vessel the Cut.
Pressure traveled through the tideworks.
The old distribution ring cracked. The water network began accepting impossible continuities.
Closing a valve had worsened one branch because pressure changed inside a system already failing to agree with itself.
The Hollowfang device had been attached before any of that. Its long baseline proved it had waited through ordinary operation. Its first major response came after the human demolition.
"No evidence it caused the lock blast," Marin said.
Venn's jaw tightened. "Obviously."
"No evidence it caused the ward fracture either. The fracture follows the pressure event and the old infrastructure."
"But they put this there."
"Yes."
"Why?"
Marin looked at the two traces.
"To see what a stressed network would do."
Kelm's expression darkened. "They knew war would stress it."
"They knew something might."
"That is generous."
"It is narrow."
He looked away. Marin understood the anger. Saint Orra had nearly drowned people through washbasins while the trace on the table began only after the blast.
Seraphine stood near the door. She had been silent since entering.
Marin turned to her. "You recognize it."
Seraphine's eyes stayed on the paper.
"The principle."
Oliver's attention sharpened.
"Lyr?"
"Field recorders. Cheap ones. You left them where a threshold was already unreliable because keeping observers on site for months was expensive."
Venn asked, "Did you create the events you recorded?"
Seraphine looked at her.
"Sometimes storms did it. Sometimes mining. Construction. Earthquakes. Fires. War, if war happened to be nearby."
Kelm's face hardened further. Seraphine saw it.
"I am not defending it."
"You sound practiced."
"I am."
The answer left the room quieter. Marin touched the edge of the paper with forceps.
"Did Lyr use a field called reference acceptance?"
Seraphine hesitated.
"Not when I was there."
"Network disagreement?"
"Similar language. Not exact."
Marin nodded and left the resemblance where it was. Oliver looked at the second trace.
"If the broken ward started accepting the device's reference, where was the reference pointing?"
Marin's attention returned to the capsule. She had avoided that question because the available answers were poor. The device had no transmitter, no obvious storage crystal beyond the stylus pickup and no mechanism large enough to project anything through the network.
Yet the cistern had shown a sky that did not belong to Saint Orra while the third contact remained close to the ring.
"We don't know," she said.
Oliver's mouth moved faintly.
"You really do make uncertainty sound attractive."
"I am trying very hard not to."
Venn folded her arms. "What can we say?"
Marin looked toward the door, where rain-dark uniforms crossed the gallery carrying bottled water uphill.
Someone outside shouted for more blankets.
A child laughed once, too loudly, probably from the aftershock of fear.
Marin lifted the stylus away from the strip and placed it beneath evidence glass.
"Say the outer lock was destroyed by naval action. Say the pressure event damaged an existing quarantine water ward. Say Hollowfang-marked equipment had already been installed to record the resulting instability."
Venn waited.
"And what don't we say?"
Marin looked at her.
"We don't say they fired the charge. We don't say they broke the ward. We say they were already here to record what happened after."
No one answered immediately. Kelm took the paper strip and began marking evidence time beside the seal numbers.
Seraphine looked toward the window. Oliver remained beside Marin, close enough that the back of his left hand touched hers on the table.
He did not turn the contact into a question or a claim.
The shadow beneath him stayed quiet in the lamplight.
Outside, engineers carried the first barrel of clean imported water into the central yard. Below them, Saint Orra's severed pipes drained themselves empty. The wounded water stopped reaching for other rooms.
