"Did Vance take the folder?" she whispered, her voice rough.
"No," I said, reaching inside my coat and handing the manila envelope across the seat gap. "He threatened to book you before two o'clock. Then he realized the dome camera above the pretzel stall was recording his hands on the paper. He crumpled his own trespass notice and walked toward the substation."
Alvarez slid behind the wheel, pulled the gearshift down into drive, and steered the sedan slowly past the row of commercial dumpsters without flashing her brake lights. "He won't stay at the substation long. Once he checks the dispatch breakroom and realizes your sister walked out through the linen bay, he's going to call County Roads and the terminal yardmaster. He has forty minutes before the shift change to sanitize the terminal server."
"He can't sanitize the off-site drive," Sarah said, turning fully in her seat, her fingers digging into the edge of the manila sleeve. "The terminal switch runs an auxiliary mirroring routine every day at noon. It dumps to an encrypted external drive inside the maintenance utility locker behind Bay 4. It’s an old physical drive, not networked to the county fiber loop. If Vance pulls the main rack breakers, the cloud logs drop, but that physical partition holds the raw axle weight metrics for every commercial hauler that crossed the scale line since June."
Alvarez checked her rearview mirror as we turned north onto the secondary bypass road. "Is the locker keyed?"
"It has a dual tumbler," Sarah answered, pulling a small brass key from her jacket pocket. The key had a notched tooth and a strip of blue masking tape wrapped around the head. "I have the utility key. But the secondary tumbler requires the facility maintenance master. Vance has that key on his department ring."
"Which means," I said, leaning forward between the front bucket seats, "he's heading there right now."
"He’s already moving," Alvarez said flatly. She tapped a mounted dashboard tablet running a muted CAD dispatch monitor. A blinking amber icon labeled UNIT 414 was crawling south along the valley industrial corridor at forty-eight miles an hour. "He cleared the mall substation six minutes ago. He didn't log an active dispatch call. He marked himself on administrative transport."
"Why haven't your people blocked the terminal gates?" I asked.
Alvarez took a sweeping curve around an abandoned aggregate quarry, her hands steady on the wheel. "Because our investigative warrant is administrative, Mr. Mercer. We have statutory authority to demand records from the regional logistics cooperative, but we do not have jurisdictional power to arrest a sworn county deputy on private industrial property without the state patrol present. The nearest state trooper unit is thirty miles north on Interstate 5, clearing an overturned tanker. If we walk into that dispatch bay with an audit notice while Vance is holding a pry bar, he can claim the drive was damaged during an electrical surge or seized under a local preservation hold. Once that drive enters the county evidence safe, it will vanish into an unsolved warehouse burglary by midnight."
The trap became immediately obvious. Vance didn't need to win a legal trial in Olympia; he only needed to create twenty-four hours of evidentiary confusion. If the physical drive was corrupted or secured under his department's seal, the state auditors would be left with Sarah’s printed screenshots and an uncorroborated ledger. The county prosecutor would call it a dispute between a disgruntled bookkeeper and an authorized patrol contractor, and the case would die quietly in an administrative arbitration hearing.
"The drive has to come out before he touches the cabinet," I said.
"We can't send Sarah back on that asphalt," Alvarez said firmly. "Her presence breaches the safety protocol we filed with the attorney general's office. She stays in this vehicle."
Sarah shook her head, turning back toward me, her knuckles white. "Nathan, you know the layout. Bay 4 isn't accessed through the front bullpen. The utility locker sits inside the compressor shed behind the wash bay. The exterior ventilation grate has an emergency latch that opens from the outside if you have the clearance pin."
She reached into her coat pocket again and pulled out a small, hexagonal steel tool no larger than an ignition key. "The wash bay operators use this to reset the water pressure valves after shift. If you slip the pin through the third louvre from the bottom, the back access panel drops outward. The drive is in a blue metal enclosure on the second shelf. It doesn't need to be unmounted; you just have to pull the high-speed data lead and slide the chassis free."
I took the steel pin from her fingers. The metal was cold against my palm. "What about the secondary tumbler?"
"The cabinet doesn't lock from the back," Sarah said, her voice dropping to a tense, urgent whisper. "The front doors have the heavy dual tumblers to keep the drivers out, but the rear maintenance panel was installed so the refrigeration techs could service the cooling coils without unlocking the main bay. If you get inside the shed before Vance unlocks the front door, you can pull the drive straight through the service cavity."
Alvarez eased the sedan onto the shoulder of an overgrown logging road half a mile east of the logistics complex. Through the screen of bare alder trees, the silver corrugated roofs of the freight terminal spread across the valley floor like a series of low steel boxes. A line of eight triple-axle dump trucks sat idling along the perimeter fence, their engines thrumming in a heavy, rhythmic bass that shook the moist air.
