CHAPTER 7: THE BACKROOM BALANCE
The door to the maintenance alcove didn’t swing smooth; its bottom edge scraped a semi-circle of white score marks into the green enamel floor paint. Inside, the air was small, choked with forty years of floor wax, dead flies, and the heavy, humid heat of a steam pipe that ran behind the electrical breaker boxes. Frank stepped over the threshold, his leather soles catching on a loose seam in the linoleum.
He didn’t turn on the overhead fluorescent bulb. The gray twilight filtering through the glass of the main hangar was enough to strike the raw edges of the metal lockers that lined the eastern wall. They were navy surplus—heavy, double-gauge iron boxes with slatted vents that had been dented and hammered back into square so many times the latches had to be forced home with a heel.
Frank stood between the lockers and the brick utility stack. His left shoulder was stiff now, a hard, cold knot of calcified muscle radiating heat down through his ribs, but he kept his forearm clamped against his side to hold the oil-soaked log paper steady beneath his denim shirt flap. He reached behind the second locker, his fingers tracking the rough, unmortared joints of the masonry where the museum’s new drywall met the original 1944 retaining wall.
The gap was only two inches wide. His knuckles scraped the brick, shedding tiny, red flakes of dry clay that fell down his sleeve like rust.
“You shouldn’t be back here, Mac,” a voice said from the open doorway.
It was Miller again, but he wasn’t on the golf cart. He stood in the frame, his heavy frame silhouetted against the wide, dim expanse of the hangar floor. He held a small, black plastic flashlight in his left hand, the beam unlit, his thumb resting flat on the rubber toggle button. He smelled of tobacco juice and the cold lard from his lunchbox.
“The director’s clerk just pulled the master manifest from the basement safe,” Miller said, his voice flat as a dry plank. He didn’t look at Frank’s hand behind the locker. He looked at the floor between them, where a small pile of swept-up metal shavings lay next to a discarded push-broom. “The registry numbers on your mimeograph don’t match the ninety-two transfer agreement. They’re showing the ordnance depot was cleaned out during the consolidation under Carter. There shouldn’t be anything under that slab but river gravel and lime.”
“The consolidation was on paper, Miller,” Frank said. His hand stopped moving behind the iron locker. His fingertips had brushed against something cold—not the powdery clay of the brick, but the dense, heavy edge of a machined iron casting. “The logistics teams from Rock Island didn’t want to transport forty tons of high-pressure storage casings across three state lines when they could just pour two hundred yards of grout over the intake valves and call it a drainage ditch. You know how they handle the dead-load.”
Miller shifted his weight, his uniform trousers whistling as his knees rubbed together. He didn’t answer right away. He tapped the plastic flashlight against his palm—three short, dull clicks that timed themselves to the distant, rhythmic thud of the main compressor out in the pavilion.
“The core drill on Tuesday is a diamond-head three-inch,” Miller murmured. He looked up then, his gray eyes catching the dim amber reflection of the safety lights from the hangar. “They’re bringing the rig in through the cargo doors at midnight. If they hit iron three feet down, they’re just going to think it’s an old footer from the crane tracks. They’ll increase the torque to clear the obstruction.”
“If they increase the torque, they’ll shear the bleed-off collar,” Frank said.
His fingers finally locked onto the object behind the locker. It wasn’t loose; it was wedged between two structural brick courses like a cold chisel. He pulled, his forearm straining until the denim of his sleeve groaned against his bicep. The metal gave with a dry, sand-paper rasp, bringing a loose chunk of grey lime mortar down with it.
It was an old-pattern manifold key—ten inches of heavy, T-shaped iron with a square-socket head that was choked with hard black graphite grease. Stenciled along the crossbar in faded white lead-paint were the numbers 044-BUNK.
Frank didn’t show it to Miller. He kept the iron vertical against his thigh, his hand wrapping around the thick stem until the cold of the casting soaked into his palm.
“The clerk found something else,” Miller said, his voice dropping into the small space between the lockers until it was almost lost beneath the hum of the transformer boxes behind the wall. “The contractor who signed off on the foundation pour in ninety-two—the one the kid’s uncle worked for. He didn’t die in retirement, Frank. He went on the payroll at Rock Island three months after the museum opened. He spent five years checking the pressure gauges on the old pipeline up by the reservoir before they tore the tracks out.”
Frank looked down at the key in his hand. The graphite grease was stiff, but underneath it, the iron was smooth, completely free of the pitting that happened to tools that had been left in the damp river soil. Someone had been maintaining this key. Someone had greased it, wrapped it, and tucked it into the masonry long after the museum had been dedicated to the public.
“He wasn’t checking the pipeline, Miller,” Frank said. He turned his face toward the door, his jaw set until the white line of the scar beneath his ear caught the light from the hallway. “He was checking the vent pressure. He was keeping the cap cold so the city could build the hotel across the road.”
A low, liquid gurgle echoed from the floorboards—a deep, rhythmic rattling through the old iron drainage pipes that ran beneath the green linoleum. It sounded like a valve trying to seat itself against ten pounds of back-pressure, the wet iron clicking twice before the line cleared with a high, thin whistle that smelled of sulfur and dead water.
Miller didn’t drop his flashlight, but his thumb moved off the toggle. He took a slow half-step backward out of the maintenance alcove, his boots clearing the green enamel sill until he was back on the wide, gray expanse of the public concourse.
“The director’s leaving at five,” Miller said, his voice flat as old iron again. “I’re locking the side gates myself tonight, Mac. If you’re still here when the night crew rotates at eight, I’ll have to log your badge as an unescorted presence.”
Frank didn’t answer. He waited until the heavy, regular scrape of Miller’s boots faded past the twin-engine displays, then he let the heavy iron T-key drop into the wide pocket of his jeans, the weight of the casting pulling the denim down until the hem dragged against his heel.
