"Marcus, it’s Toby." His voice was shaking so violently the syllables clipped together, but he was breathing. "I’m in Miller’s tack room. Mr. Miller’s got the doors barred from the inside and his deer rifle across his knees. I ran through the drainage ditch like you said. My boots got sucked off in the mud, but I made it."
A band of iron loosened around my ribs, though the relief lasted less than two seconds. "Did they see you cross the pasture?"
"No, but they weren't looking for me, Dad," Toby whispered, the background filled with the faint, steady lowing of Miller’s dairy cattle. "They had two trucks. A black flatbed and a marked county patrol unit. Deputy Kallen was standing right on our gravel apron in his uniform coat, holding a flashlight while two guys in black work jackets carried the big steel fire locker up the basement stairs. They didn't touch the television or the silverware. They loaded the locker into the flatbed, strapped a tarp over it, and then Kallen took a heavy pry bar to the front door frame to make it look like a kicked-in latch."
"Did they leave?"
"Ten minutes ago," Toby said. "Kallen drove east toward Highway 169. But Dad, before they pulled out, Kallen handed the driver a blue clipboard. He said something about the junction at MP 342. He told them, 'The rail grinder crew is already staged at the siding. Once the head cuts the crown, Cole won't have a single weld to test.'"
The steering wheel felt like dry ice under my palms. MP 342 was Milepost 342—the West Des Moines crossover, where the mainline frogs took the brutal forty-ton pounding of the daily unit trains. Vance hadn't just dispatched Apex to strip my workshop of digital drives; he had coordinated with Empire’s regional dispatch to run a heavy rail-grinding consist over the fractured manganese frog tonight. If a ten-ton rotary grinding head shaved an eighth of an inch off the railhead, the epoxy filler and the micro-stress fractures would be obliterated into iron dust, leaving a smooth, shiny steel surface that would pass a visual inspection at sunrise. The physical evidence on the track would be destroyed eight hours before the federal board in Omaha could issue a preservation order.
"Toby, stay in that tack room with Arnie," I told him, checking the glowing clock on the instrument cluster. 7:22 PM. "Don't turn your phone on. Don't let Arnie call the sheriff’s desk again. Kallen owns that dispatch line tonight. If anyone comes down Miller’s lane who isn't driving a marked Iowa State Patrol car, you head out the back hay door into the creek bed."
"Dad, what about the Omaha hearing?" Toby asked, his voice cracking with the strain. "If they have the locker, they have everything."
"They have the field backups," I said, looking down at the matte black case beside me. "They don't have the spectrometer raw files. I'm three hundred miles out. Hang on."
I cut the call, dialed the direct extension for Frank Delvecchio, the night trainmaster at Empire Rail’s Valley Junction classification yard, and hit the speaker toggle. Frank had worked track maintenance for thirty-two years; he had lost two fingers to a broken knuckle coupler in the nineties and hated Garrett Vance with the quiet, stubborn fury of an old railroader who still remembered when safety flags weren't negotiated by corporate attorneys.
The line rang four times before Frank picked up, his voice competing with the pneumatic roar of diesel switchers idling in the yard. "Valley Junction, Delvecchio."
"Frank, it's Marcus Cole. Don't say my name out loud."
A long silence hung over the line, punctuated by the clank of distant steel wheel flanges. "Marcus? Where the hell are you? Vance’s office sent an all-stations teletype two hours ago. Said you walked off site during an unannounced audit and might attempt to tamper with track infrastructure before tomorrow's board session. They put your name on the gate security board."
"Frank, look at your dispatch terminal right now," I said, leaning closer to the dashboard microphone as I passed a snowplow throwing salt across the passing lane. "Look at the work orders logged for Milepost 342 between eleven tonight and dawn."
I could hear the clatter of Frank’s heavy fingers on a mechanical keyboard, the dull clicking of a legacy green-screen terminal that had survived three corporate mergers. Then his breathing slowed.
"Work Order 44-Bravo," Frank muttered, reading slowly. "Emergency surface remediation. Rail Grinder 109 cleared to occupy the main track at MP 342 from 11:30 PM to 2:00 AM. Authorized by executive waiver... Vance's digital signature key." Frank paused, the line deadening as the implications hit him. "The westbound ethanol manifest, Train 688, is scheduled through that block at 4:15 AM. Marcus, you flagged frog 14 at that exact crossover last Thursday for subsurface web cracking. If they grind that head down without replacing the casting, the dynamic wheel load from sixty tank cars will snap the frog base like peanut brittle."
"They aren't replacing it, Frank. They coated the fissures with marine epoxy last month and spray-painted the web to pass the visual. Vance is using the grinder to destroy the fracture trail before the Omaha board can take silicone casts tomorrow morning."
