Chapter 7
The brine in the interview room had crept past the welt of our boot soles, pooling two inches deep against the baseboard heaters. Kiliā felt the cold water through her leather, but she refused to look down, unwilling to break eye contact while Kanoa's bronze diver tag sat between our palms. She wanted to believe her brother was an innocent bystander who stumbled into an industrial meat grinder. I needed her to understand that Kanoa was an engineer who smelled the rot in Hauāka long before I ever turned a valve.
When I climbed the iron rungs to the crane runner at 07:28 that morning, Kanoa was sitting on an inverted cable drum forty feet above the sump. His neoprene suit was unzipped to the waist, exposing a sweat-stained gray undershirt. A heavy brass spanner rested across his knees, balanced with the casual ease of a man who worked high iron without a safety harness.
"You took three-quarters of a turn off the pilot needle," Kanoa said before my boots cleared the grating. "Cavitation hammer tripped the hydraulic differential. Sluice slammed shut. Lockout timer is running."
I did not reach for my utility knife. If Kanoa wanted to drop a spanner on my skull, he would have done it while my back was turned on the ladder. "You have good eyes from up here."
"I have ears," he said, tapping the side of his helmet harness. "You sounded like an amateur trying to strip a corroded thread. Uluwe is on the phone with the surface office right now, screaming about grid instability."
"Let him scream," I said. "He has ten minutes before the automated telemetry terminal transmits the morning burst to the district board."
The dry-well recess at the end of the crane catwalk housed the station's auxiliary telemetry buffer: a clattering, mechanical relay rack that stamped pressure differentials onto paper tape and broadcast the digital summary to the regional utility office via dedicated copper line. If the transmission showed a sudden, localized pressure drop on the pilot line, the district board would dispatch an independent forensic team within six hours. Uluwe would be demoted, but I would be in federal custody before sundown.
I knelt in front of the gray terminal cabinet, using my brass shim to trip the maintenance override on the front housing. Inside, the brass selector wheels were already indexing the 07:14 pressure trace.
"What are you doing to the reel?" Kanoa asked, stepping off the cable drum and walking silently along the steel I-beam behind me.
"Giving Uluwe exactly what he earned," I said.
Last month, Uluwe had deferred the quarterly descaling of the secondary manifold to keep the station's operational efficiency numbers above ninety-eight percent. He had filed three duplicate memos claiming the thermal transducers were drifting, refusing to authorize a mechanical purge.
I pulled the calibration potentiometer on the transducer interface two notches to the left, introducing a synthetic minus-four-millibar offset into the baseline curve. Then I re-indexed the punch-wheel carriage, shifting the timestamp of the cavitation spike by fourteen minutes to align perfectly with the routine morning pump cycle.
When the district board received the burst at 07:30, the graphs would not show deliberate valve tampering. They would show a textbook pressure surge caused by chronic sediment accumulation in an uncleaned manifold. The telemetry would indict Uluwe's deferred maintenance schedule to four decimal places.
"If Uluwe spent half as much time greasing pipe flanges as he does squaring carbon copies on his clipboard," I muttered, locking the cabinet door, "we wouldn't need to doctor his logs to keep this station afloat."
A dry, rustling laugh came from Kanoa's chest. "He filed six incident reports because my dive team used the wrong grade of sealing wax on the battery housings last week. The man treats grease like a moral failing."
The relay clattered shut behind the steel panel. A burst of high-frequency pulses chattered through the copper dry riser, shooting the altered record to the harbor surface. Uluwe was now on the hook for a major hydraulic fault, and he had no paper trail to prove otherwise.
Kanoa leaned his shoulder against the painted conduit, staring down through the iron mesh floor into the black water of the lower gallery. The yellow grease-pencil marker was still tucked behind his ear.
"You didn't trip that gate to protect the pumps," Kanoa said softly. His voice dropped beneath the hum of the auxiliary exhaust fans. "You tripped it to keep my dive team out of the intake cradle."
I stood up, keeping my gloved left hand hooked inside my belt. "The intake was fouled."
"I know what was in the pipe, Māhina," Kanoa said. He did not look at me. He looked at the massive intake throat where the steel sluice gate hung frozen under the three-hour lockout. "Two days ago, I did a routine sweep on the outer trash racks. I saw the zinc anodes. They weren't corroded by saltwater. Something had bitten through a four-inch solid casting."
He turned his head, his dark eyes fixing on mine with a calm, terrifying clarity.
"You bought us three hours," Kanoa said, tapping his wrist where the lockout timer was counting down. "So tell me, engineer. What are you going to feed it when the gate opens?"
