Arthur stared down the dark spur, the implication hitting him with total finality. "That wing holds the entire twenty-two-million-dollar municipal grant collection. If we flood that gallery, the restoration bond defaults automatically. The city takes receivership of the pavilion at daylight."
"Then Gabe drowns," I said, holding his gaze in the yellow glare of the lantern. "Make your choice, Arthur. Your daughter’s bond, or my mechanic’s life."
The old contractor didn't hesitate. The arrogance that had let him sit through Julianne’s opening speech vanished, burned away by the sound of a young man hammering on boiler plate thirty feet beneath the earth.
"Give me the bar," Arthur said.
He shoved the chisel tip of the iron spud bar into the dog track beside my knee, bracing his shoulder against the wet concrete. "On three, Nathan. You trip the bypass. I’ll split the wedge."
I didn't answer with words. I turned and waded twenty yards through the freezing current down the south spur, my boots slipping on the slick silt floor until I reached the yellow bypass wheel. The inspection seal was dated six months earlier, signed in my own handwriting before Julianne had locked me out of the mechanical rooms. The chain around the stem was held by an administrative lockout tag with her initials printed in indelible purple ink: JV - DO NOT OPERATE UNDER ANY CIRCUMSTANCE.
I set the jaws of my cutters over the brass stem, snapped the padlock, and grabbed the rim of the yellow wheel with both hands.
"Gabe!" I yelled back over the rushing noise of the tunnel. "Grab the top rung! The floor's dropping!"
I threw my whole frame against the wheel, spinning it counter-clockwise against forty pounds of rusted resistance. The bronze screw groaned, threaded out three inches, and then the internal gate broke free with a shuddering crash that shook the bedrock beneath my boots.
A hundred yards away, beneath the polished floors of the grand exhibition wing, the sound of tearing drywall and shattering plate glass rolled through the building. The bypass conduit swallowed thirty thousand gallons of river surge in ten seconds, roaring like a freight train through the decorative lower halls.
At the bulkhead, Arthur Vance threw his entire body against the iron bar, driving the chisel edge between the keeper and the door frame. The lower wedge gave way with a deafening metallic screech. The differential pressure collapsed.
The heavy steel door swung outward into the corridor, releasing a four-foot wave of dark river water that knocked Arthur off his feet and sent me sliding back against the conduit racks.
Through the foaming backwash, Gabe Reyes tumbled out onto the concrete floor, coughing up silt and clutching a sealed canvas dispatch pouch tightly against his ribs.
CHAPTER 3: The Proof Beneath The Broken Floor
I grabbed Gabe by the canvas harness, hauled him clear of the receding backwash, and dragged him up onto the dry concrete landing at the base of the stairwell. His lips were blue, his knuckles scraped down to raw tissue, but his fingers remained clamped around the brass zipper of the water-tight dispatch pouch. Arthur Vance dropped the iron spud bar into the sludge with a dull clank, braced his hands on his trembling knees, and coughed the sulfurous stench of river silt from his lungs. The sound of water thundering through the south bypass into the exhibition wing below shook the cinderblock walls around us like an ongoing freight derailment, but the level on our landing was already dropping toward the floor drain in sheets of gray foam.
"Can you breathe, Gabe?" I asked, stripping his sodden work coat off his shoulders.
Gabe spat a mouthful of brackish slime onto the concrete, drawing in three sharp, rattling breaths that hitched in his chest. "I took the logbook... off the desk before the glass blew, Nathan. And the manual override slips... she left on the telemetry board."
Arthur looked down at the boy, his voice dead and hollow. "What override slips?"
"The paper permits your daughter signed at five this afternoon," I told Arthur, taking the pouch from Gabe’s hands. "The ones telling my crew that the city variance had cleared, and that any worker who touched the manual release on Sump Three would be terminated on the spot without union arbitration."
Arthur closed his eyes for two seconds, his chest rising and falling beneath his ruined, grease-stained dress shirt. When he opened them, the last shred of paternal defense had vacated his face, replaced by the grim, transactional certainty of a man who realized every contract he had ever signed was about to be subpoenaed by the county prosecutor.
