"If the bypass was closed at four-ten," I said, keeping my tone quiet so the passengers across the aisle wouldn't lean back into the walkway, "the main line pressure on the Columbia lower reservoir would spike within twelve minutes. The district telemetry system would have alarmed every monitoring screen in the county dispatch center."
"It didn't alarm," David said. He pulled a folded sheet of printout paper from inside the lining of his coat. The sheet had been torn from a dot-matrix ledger roll, the green-and-white perforated margins still attached along the edges. "Because at three-fifty, someone plugged an override loop into the terminal rack in the utility basement. The monitoring center saw normal static pressure while twelve hundred gallons a second were being diverted into the old quarry culvert behind the chemical depot. And at four-fifteen, the county sheriff’s substation received a call from the regional supervisor reporting that Mark had walked off shift, left the intake unsecured, and couldn't be reached by phone."
I looked down at the printout. It was an equipment release receipt from Mid-State Industrial Supply—my employer. At the top of the header, the date was stamped yesterday morning: Order 8841-A: Four-inch high-pressure bypass blind flanges, six units. Picked up by: Transit Utility Services, Van 12.
Transit Utility Services was the name printed on the high-visibility vests worn by the three men who had just walked through Car Nine with their phone cameras raised.
"They aren't state inspectors," David said, his fingers tightening against the edge of the laminate table until the knuckles went white. "They're contract maintenance men hired by the chemical depot's parent company. Two hours ago, they showed up at the municipal clinic where I work as a physical therapy aide. They brought two off-duty county deputies with them and a signed emergency psychiatric commitment claiming I had assaulted an orderly while raving about the river station. They put this band on my wrist before they even took my coat. They didn't take me to the county hospital; they put me in the back of an unmarked transport van parked behind the loading dock."
"How did you get on this train?" I asked.
"Mark called me at three-thirty from his personal cell," David said. His voice dropped lower, steadying itself against the loud iron clatter of the river bridge below us. "He told me he found six blind flanges hidden under a tarp in the maintenance shed, Flanges that had our company's inventory tags on them. He told me someone was planning to dump the untreated runoff from the depot's retention ponds into the river main while the river was running high from the spring thaw, using his shift as cover. He told me to go to his locker at the Columbia maintenance shed and take the backup logbook before the night shift arrived. When I walked into the clinic parking lot to get my truck, the transport van was already blocking my bumper."
The train began to slow, the brake shoes grinding against the steel wheels with a long, shrill whine that vibrated through the floorboards. The overhead lights flickered once, dimmed to an amber emergency glow, and then snapped back to harsh fluorescent white.
Up ahead, through the tinted glass of the sliding vestibule doors, the lead man in the transit vest reappeared. He wasn't holding his phone now. He stood in the narrow passage between Car Eight and Car Nine, his radio pinned to his shoulder strap, watching the back of David’s head through the reinforced wire glass. Standing behind him on the platform vestibule was a uniformed Amtrak conductor holding an electronic handheld ticket scanner and a yellow plastic clipboard.
"They're not going to drag me off in the aisle," David whispered. He slid the brass key and the folded dot-matrix sheet toward my overnight bag. "They want the conductor to identify me as a passenger without a ticket who matches an active county elopement warrant. Once the local police take custody at Columbia station, the paperwork locks me into a seventy-two-hour evaluation hold with no outside calls. And by midnight, the overflow valves at Station 4B will be sealed shut, the bypass flanges will be bolted in place, and Mark will be officially listed as an employee who fled an industrial sabotage investigation."
The train shuddered as it hit the switch frog, rocking heavily to the left. The conductor tapped his electronic scanner against the door frame, waiting for the safety lock to release.
I looked at the delivery slips in my breast pocket. The top slip was an unfulfilled order for six ductile iron gate valves consigned to the Columbia Water Works, signed by District Supervisor Harold Vance—the same supervisor who had authorized the contract maintenance crew. Beneath Vance’s signature was the dispatch timestamp from our warehouse: Picked up by authorized courier, 2:45 PM.
I didn't give the brass key back. I unzipped the side pocket of my canvas bag, dropped the heavy key inside, and slid the dot-matrix ledger sheet between two carbon copies of my own company's invoices.
"When the conductor opens that door," I said, reaching into my coat and pulling out my company employee badge with its laminated photo and clip, "you don't say a word. You look out that window and keep your left hand in your pocket. I signed for the warehouse release on those bypass flanges six hours ago, and I know exactly which truck hauled them out of the yard."
CHAPTER 2 CONTINUED
"Folks," the conductor said, his voice flat with the tiredness of a shift that had begun before dawn in Philadelphia. "Columbia station is an unscheduled operational flag. Local authorities have a passenger inquiry on this equipment. Keep your seats and have your paper stubs or digital barcodes visible on the armrests."
David did not flinch, but his right shoulder pressed harder against the frame of the window. His left wrist stayed deep in his coat pocket, hidden beneath the heavy flannel lining, yet I could hear the faint, dry rustle of the torn vinyl hospital band rubbing against his shirt cuff. Across the aisle, the two passengers who had spent the last twenty miles filming lowered their screens into their laps, suddenly quiet now that an official uniform filled the walkway.
"Ticket," the conductor said, stopping at row fourteen. He was looking at David’s boots, taking in the dried red mud caked into the leather welt, the exact clay that lined the drainage ditches flanking the river intake gates.
"We're together," I said.
