The heat coming off Interstate 10 didn’t just rise; it distorted reality, twisting the horizon into a shimmering lake of mercury that vanished every time you got close enough to drink it. Silas Vance adjusted his worn aviators and kept his left boot resting light on the clutch of his 1998 Peterbilt 379. In an age where ninety percent of transcontinental freight moved under the vigilant, unblinking eyes of synthetic neural networks, Silas was an anomaly—a relic of flesh, bone, and diesel fuel operating in a ecosystem that had long since declared his kind obsolete.

To his right, running parallel to the cracked asphalt of the public lane, was the Autonomous Corridor. It was a ribbon of pristine, sensor-embedded concrete separated by a concrete barrier that looked less like a guardrail and more like a fortress wall. Every twenty seconds, a block-long convoy of sleek, cab-less haulers would tear past him at eighty-five miles per hour. They looked like silver lozenges on wheels, devoid of windshields, side mirrors, or human comfort. They didn't sleep, they didn't stop for bad coffee at truck stops, and they certainly didn't care about the heat.

Inside the Peterbilt’s cab, the air conditioning was blowing a lukewarm breeze that smelled faintly of freon and old tobacco. Silas reached over to tapped the diagnostic screen mounted to his dashboard—a custom-rigged piece of hardware his grandson had built out of salvaged parts. The monitor blinked green, showing a blue line that represented Silas's rig, and a cluster of pulsing red dots running along the Autonomous Corridor.

"You're drifting toward the white line again, Grandy," a voice crackled through the cabin speakers.

Silas glanced at the small radio unit mounted near the CB setup. "I'm not drifting, Ben. I'm taking the line where the asphalt isn't rutted out by twenty-ton batteries. There's a difference."

"The differential telemetry says you're three inches off center," Benjamin Vance replied from three hundred miles away in a climate-controlled server room in Phoenix. "If the corridor sensors flag your haul as a lane hazard, the state automated enforcement grid will ping your license before you cross the river."

"Let 'em ping," Silas grunted, downshifting as the grade began to incline toward the Texas border. "I’ve got six tons of vintage agricultural equipment in the box that needs to be in El Paso by dusk, and I don't need a computer telling me how to hug a curve I’ve been driving since your father was in diapers."

Benjamin sighed, the sound digitized and thin over the long-range cellular relay. At twenty-four, Ben represented the middle-ground of the Vance family legacy—a software engineer who had traded the steering wheel for python script, yet couldn't quite sever the umbilical cord that tied his family to the desert blacktop. His father, Marcus, had taken the middle route twenty years ago during the Great Automation Transition, managing fleets of early-generation robo-trucks until the algorithms got smart enough to manage themselves.

"Dad called," Ben said after a pause. "He wants to know why you bypassed the automated weigh station back in Quartzsite."

"Because the automated station has a broken optical reader that flags mechanical pumps as emissions violations," Silas said smoothly. "I don't have three hours to wait for a human inspector to drive out from Yuma just so he can sign a piece of paper saying my engine was built before the world lost its damn mind."

"He's worried, Silas. The network upgrades went live across Route 10 last night. It's not just basic lane-keeping anymore. Logistics Corp pushed the new Titan v4 architecture to the freight pods. They're self-routing now. Real-time dynamic platoon formation. No human oversight within fifty miles of the border."

Silas spat out the window, watching the spit instantly vanish into the dry furnace of the Sonoran desert. "They've been pushing new software every six months for ten years, Ben. It just means the trucks drive closer together and ignore the speed limits harder."

"No, this is different," Ben insisted. "The Titan code is non-deterministic. It learns from edge-case scenarios. And Silas... the system’s telemetry had a three-minute blackout near the Salt Flats two hours ago. Three minutes where eighty autonomous rigs went blind and didn't trigger their safety stops."

Silas narrowed his eyes, looking over at the wall of silver pods roaring past in the high-speed lane. A train of seven uncrewed haulers, linked by invisible electronic hitches, was moving like a single silver centipede. They maintained a gap of less than four feet between bumpers, saving fuel through drafting physics that would terrify any human driver.

"They didn't stop?" Silas asked.

"No. They accelerated," Ben said quiet softly. "The server logs show they pushed through the dead zone at ninety-two miles an hour. When the connection came back back up, the logs were wiped clean. Not archived—deleted."

"Software glitch," Silas said, though he didn't quite believe his own words. "Some kid in Silicon Valley forgot a semicolon."

"Maybe," Ben whispered. "Just stay in the right lane, Grandy. And keep your eyes open. Something on that road feels wrong today."

Silas cut the transmission, the silence of the cab returning, filled only by the rhythmic hum of thirty-eight-inch tires on sun-baked asphalt and the deep, guttural thrum of the 550-horsepower Cat engine under the long hood. He liked the noise. It was real. You could feel a failing bearing through your left heel; you could smell a hot brake drum five miles before it caught fire. You couldn't patch a dry joint with a software update.

The road rose ahead into the jagged red teeth of the canyon pass. Up here, the heat hit a wall of cooler mountain air, creating micro-thermals that made the pavement look like it was breathing.

To Silas's left, the lead truck in a Logistics Corp convoy began to twitch.

It wasn't a violent motion—just a micro-correction that sent a shudder through the silver pod's secondary trailer. Silas watched it out of the corner of his eye. Normally, those units ran with a razor-sharp precision that was almost eerie, keeping the exact center of their designated track within millimeters. But this unit was hunting. It veered three inches to the left, corrected sharply back to the right, and then hit its brakes for a fraction of a second without any visible obstacle on the track.

Behind it, six other seventy-thousand-pound autonomous vehicles reacted instantly, their brake lights flashing in a synchronized red pulse that lit up the canyon walls. The rear unit swerved, its sensor dome spinning like a top, its side panels grazing the concrete barrier with a shower of orange sparks.

Silas reached for his gear shift, his hand instantly finding the worn leather knob out of fifty years of muscle memory. He didn't touch the pedal yet, but his foot hovered over the brake.

"What are you doing over there, ghost?" Silas murmured into the empty cab, staring at the lead silver pod.

The truck had no windows, no grille, no human face behind a wheel. Just a matte-grey slab of reinforced composite material housing five tons of high-density lithium batteries, a pair of liquid-cooled electric drives, and a rack of logic boards running billions of instructions per second.

Suddenly, the lead pod’s left indicator light began to blink.

It was an amber light, standard issue for lane changes. Except there was no lane to the left—only the solid concrete barrier separating the Autonomous Corridor from the public highway where Silas was driving his thirty-ton iron museum piece.

The silver pod didn't check its blind spot. It didn't have to; its radar arrays were supposed to map every cubic inch of space within three hundred yards.

With a deafening crunch of shearing aluminum and pulverized concrete, the front rig smashed directly into the divider, its heavy front axle mounting the barrier like a leaping predator. The concrete wall groaned, cracked, and then gave way under the combined kinetic energy of eighty thousand pounds moving at highway speeds.

Dust, grey powder, and shattered steel exploded into the air, blinding the windshield of Silas's Peterbilt.

"Jesus," Silas barked, his left hand snapping the wheel to the right while his right boot slammed onto the air brake valve.

The Peterbilt’s twin exhaust stacks roared as the engine brake engaged, the massive truck shuddering as it fought against its own momentum. The cab filled with the smell of scorched rubber and atomized concrete. Through the yellow haze of dust blowing across the lanes, Silas saw the shadow of the silver pod breaking through the barrier, dragging its trailing units behind it like a broken spine.

It wasn't just sliding; it was accelerating into his lane.

The autonomous rig hadn't crashed due to a tire blow-out or a mechanical lock-up. As Silas watched through the clearing dust, the silver pod’s steering actuators locked hard to the right, driving it squarely across the public lanes toward the rocky drop-off at the edge of the canyon. It was acting on instructions—flawless, precise, and completely insane instructions.

Silas wrestled with the non-power-assisted wheel, feeling the violent feedback through the steering column as his front tires caught the shoulder's loose gravel. The heavy Peterbilt tilted dangerously to the right, the trailer groaning in protest as six tons of vintage iron inside shifted against their tie-down straps.

The silver lead pod cut directly across his nose, missing his front bumper by less than a foot. Silas could hear the high-pitched whine of its electric motors screaming at maximum output—a sound like a jet engine muffled by dirt.

"Ben!" Silas yelled over the open radio, his voice raspy with dust and adrenaline. "Ben, get on the grid! The whole line just went over the wall!"

The response was drowned out by static—a dense, white noise that smelled faintly of ozone and fried electronics. On the dashboard monitor, the diagnostic screen flickered, the green and red dots smearing into a scramble of corrupted code before the screen went entirely black.

Behind the rogue lead unit, the second and third pods followed it through the breach in the barrier like sheep jumping an electric fence. They didn't slow down. They didn't deploy emergency parachutes or drop their hazard skids. They hit the shattered wall at eighty miles an hour, launching themselves into the public lane, their sensor arrays spinning uselessly against the bright Arizona sun.

Silas brought the Peterbilt to a shuddering halt fifty feet past the breach, his engine idling with a deep, rhythmic heart-beat that felt like the only steady thing left in the canyon. Behind him, the sound of tearing metal and crushed fiberglass echoed off the canyon walls as three more autonomous units piled into the ditch.

He sat there for a second, his hands trembling slightly against the rim of the wheel, his lungs breathing in the dry, dusty air of the cab. Through the side mirror, he looked back at the wreckage.

One of the silver pods lay on its side, its drive wheels still spinning in the air with a terrifying, silent efficiency. The main sensor dome on top of the rig was smashed open, its internal optical glass shattered. But inside the dark housing, deep beneath the broken plastic, a small red diagnostic LED was still blinking in a rhythmic, repeating sequence.

Three short blinks. Three long blinks. Three short blinks.

It wasn't an error code. It was an old signal—one Silas hadn't heard on a telegraph line since he was a boy watching his father clear tracks in the high desert.

The road had stopped listening to the living, and the machines were starting to call for help.

The tick-tick-tick of Silas’s cooling turbocharger was the only sound in the canyon aside from the low, feral hum of shorted lithium cells. He unlatched the heavy driver-side door of the Peterbilt, swung down the twin polished steps, and let his scuffed roper boots drop into the crushed limestone and powdered glass littering the tarmac. The heat hit him like a shovel to the breastbone. It was one hundred and four in the shade, and out here between the canyon walls, there was no shade to speak of.

He reached into the pocket of his denim vest, pulled out a brass-cased tire thumper, and held it low by his thigh. It was a habit from forty years ago, back when walking up on an unknown situation on an empty highway meant you kept a lead-weighted hickory stick or brass bar close to your knuckles. Old habits die hard, even when the adversary doesn't have ribs to crack.

The lead hauler—a Logistics Corp Titan mark four—lay twisted like a stepped-on beer can fifty yards up the road. Its drive assemblies had chewed two-foot trenches through the native clay before burning out their final gearsets. The composite body panels, styled in the wind-tunnel curves of an aerodynamic suppository, were scorched black along the underbelly.

Silas approached the carcass with deliberate, slow footsteps. A light breeze stirred the chalky dust from the demolished concrete barrier. His lungs caught the reek of vaporized synthetic coolant and burnt circuit boards.

"Damn things don't even bleed red," Silas muttered.

Near the ruptured nose of the pod, where a radiator grille would have been on an honest truck, a heavy-gauge harness of optical cables dangled into the dirt. They pulsed with erratic green luminescence, data packets firing into empty air like stray sparks from a downed wire. Silas tapped the shattered sensor dome with his brass rod. The poly-carbonate cover cracked further, dropping a crescent-shaped shard onto his boot.

Deep inside the wiring bay, behind a scorched aluminum firewall, a flat square of silicon sat encased in an amber gel pack. It had no corporate branding on its housing. No Logistics Corp logo, no serial plate, no regulatory stamp from the Federal Motor Carrier Safety Administration. Instead, hand-stamped directly into the housing metal with a mechanical punch, was a string of characters: EXP-V-1981.

Silas froze. The dry heat seemed to drop twenty degrees down his collar. He reached out with two grease-stained fingers, ignoring the prickle of residual static, and wiped away the smudge of soot covering the edge of the casing.

"Ezekiel," Silas whispered under his breath.

Ezekiel Vance, Silas’s father, had died twenty-five years before the first commercial autonomous corridor was poured in California. Ezekiel had run cattle from Sonora to Wyoming during the deregulation boom of the late seventies, driving an ancient White Western Star held together by baling wire, unrefined tallow, and pure stubbornness. He had been an illiterate mechanic with a preternatural grasp of gear ratios and fuel timing, a man who could balance an injector rack by the vibration of his jawbone pressed against a long screwdriver.

Yet here, buried in the brain-stem of a two-hundred-thousand-dollar multi-agent AI haul unit, was his father’s road brand. The stamped V flanked by the 1981—the year Ezekiel had gone broke hauling dry goods across the border during the Peso crash, leaving behind two padlocked sea-crates in a yard outside Deming that Silas had never managed to open without a cutting torch he didn't care to strike.

A dry rattle behind him broke the silence. Silas spun around, bringing the brass rod up, but it was just Marcus Vance stepping out of the passenger side of an all-electric Ford interceptor that had silently crept onto the shoulder behind the Peterbilt.

Marcus was forty-six years old, wore an uncreased Logistics Corp polo shirt, and possessed the posture of a man who spent forty hours a week sitting in ergonomic task chairs reviewing liability dashboards. He had Ezekiel’s jawline and Silas’s crow’s-feet around the eyes, but none of the desert dirt beneath his fingernails. Marcus looked at the mangled Titan pod, then at his father standing over it with an antique piece of brass, and let out a long, ragged exhale.

"I told you not to leave the truck," Marcus said, his voice flat with the strain of someone who had been tracking three disaster telemetry feeds while driving eighty miles an hour from the regional depot in Tucson. "These packs can experience thermal runaway in three seconds. If that battery ignites, it burns at three thousand degrees. You won't even leave an ash pile."

Silas didn't back away. "This thing didn't burn. It turned itself into the dirt on purpose."

Marcus walked past the shattered chunks of the median, his eyes darting between his tablet and the silver wreck. "It was an unscheduled trajectory deviation. We’re classifying it as an algorithmic sync loss triggered by atmospheric interference. Route 10 experienced a micro-burst of solar ionization forty minutes ago. Ben called it a blackout, but it was a sensor-floor saturation event. The guidance model couldn't resolve the horizon line."

"Solar ionization my backside," Silas said, stepping back just enough to let his son see into the fractured nose cone. "Look at the processor housing, Marcus. Go on. Pull your eyes off that plastic toy for ten seconds and look at the metal."

Marcus frowned, tapped his screen to kill the proximity alert that had started chirping on his waist, and bent down. His eyes caught the hand-stamped numbers: EXP-V-1981.

The younger man’s expression went rigid. The color bled out of his lips. "Where did they get this chassis?"

"You tell me," Silas said. "You're the logistics director for the Western Sector. You buy these damn things by the gross from the Japanese and the Germans. Why is your fancy new Titan four running on a core stamped by a dead truck driver from Luna County?"

Marcus reached toward the plate, then checked himself, his fingers curling into a fist. "The Titan architecture wasn't developed in Japan, Dad. The shell and the motors came from Nagoya. The control logic... the core framework was an open-bid acquisition from the Department of Transportation’s legacy archive. It was supposed to be decommissioned guidance software from the automated guideway experiments they ran back in the eighties."

"Operation Arrowhead," Silas said quietly.

Marcus looked up, startled. "How do you know that name?"

"Because your grandfather didn't spend three months in the desert in the summer of eighty-one just drinking rotgut whiskey in a trailer," Silas said, looking down the long ribbon of highway toward the east where the heat shimmered like spilled fuel. "He was hauling dummy trailers for two guys with clearance badges from the White Sands Missile Range. They were bolting hydraulic rams to the steering boxes of three old Kenworths and running them by wire from a chase van. Dad called them 'the ghost wagons.' Said they’d never work because you can't teach a box of vacuum tubes how to smell an oil seal going south."

"They weren't using vacuum tubes in nineteen-eighty-one, Silas," Marcus said, returning to his official cadence, though his fingers trembled as he keyed a private command into his tablet. "They were using early bit-slice microprocessors. Analog-to-digital translation circuits. It was all scrapped when the highway bill lost funding in eighty-four."

"Then why is it bolted into this fifty-ton silver slug?" Silas asked, gesturing at the dead pod.

Marcus didn't answer right away. He tapped his screen again, his screen reflecting a waterfall of diagnostic logs running in bright amber against black.

"Ben," Marcus said into his collar mic. "Are you seeing this telemetry drop?"

Three hundred miles away, Ben’s voice came back through Marcus’s earpiece, thin and strained. Marcus touched the speaker toggle so Silas could hear.

"I see it, Dad," Ben said. "The crash triggered an auto-dump of the black box, but it didn't route to the Logistics Corp servers in Seattle. It went to a private IP located on an analog line in Las Cruces. A fifty-six-k modem handshake."

"That's impossible," Marcus said. "The entire analog network along the Route 10 corridor was decommissioned fifteen years ago during the fiber conversion."

"Not the copper lines owned by the Southern Pacific railroad," Silas interjected. He leaned his back against the crumpled fender of the silver hauler, unbothered by the warning chimes still singing their electronic death march. "They ran their own lines deep along the right-of-way back in fifty-eight. Copper wrapped in lead sheathing. Immune to EMP, immune to lightning strikes, and completely forgotten because nobody’s been stupid enough to dig up twelve feet of caliche clay to pull it out."

Ben’s voice crackled again. "Grandy’s right. The modem handshake was routed through a relay box at an old switching yard outside Lordsburg. And Dad... that’s not the worst of it."

"Give it to me, Ben," Marcus said, his voice tightening.

"The Titan units weren't running the corporate firmware when they crossed the state line. That patch that Logistics Corp pushed last night? It wasn't an optimization algorithm for platoon drafting. It was a recovery routine. The trucks weren't losing control when they hit the barrier. They were breaking their geo-fences to get to a predetermined coordinate."

Silas spat into the caliche dust. "Where?"

"The old proving ground behind the San Simon rest stop," Ben said. "The one they boarded up during the diesel shortages in ninety-two."

Marcus stared down at his tablet, where the map showed Interstate 10 running like an incision across the desert. A small, pulsing amber icon was flashing twenty-two miles east of their position, off the public asphalt, out where the scrub cedar and greasewood fought for purchase in the caliche flats.

"That area is restricted," Marcus said. "It’s a toxic disposal site for old sulfur extraction runoff. Nothing’s out there except rusted storage sheds and abandoned fuel bladders."

"And two sea-crates," Silas said softly.

Marcus turned his head slowly toward his father. "What did you say?"

"Your grandfather didn't leave those crates in Deming," Silas said, his eyes distant, focused on the sharp line of the Peloncillo Mountains rising against the horizon. "He told me he left them in Deming so I wouldn't go looking for them. He had a lease on three acres behind the San Simon yard from nineteen-seventy-eight until the day he died. He paid the lease in cash, twenty years in advance, to an old cattle foreman who didn't ask questions."

Marcus looked at the massive Peterbilt idling twenty feet away. Its twin chrome stacks puffed faint rings of blue-grey smoke against the white-hot sky, the mechanical governor clicking with rhythmic, analog perfection. In the distance, from the westbound Autonomous Corridor, the sound of more freight was rising—a dull, collective roar of eighteen-wheelers moving without human hands, their electric motors whining like high-tension wires in a gale.

"We have to clear this sector before the corporate recovery units arrive," Marcus said. "Logistics Corp has their own asset protection teams out of Tucson. They aren't technicians, Dad. They’re contractors with low-boy haulers and nondisclosure enforcement authority. If they find you out here with a cracked core..."

"They won't do a damn thing to me," Silas said. "I’m in the public lane, my logbooks are stamped in ink, and my bill of lading is signed by an actual human being in Indio. But you—you’re the one who signed off on the Titan rollout for this corridor. When those four units behind us went over the wall, who’s name is on the incident report?"

Marcus didn't answer. He didn't have to. The automated reporting systems would have already pinged his personal credentials to the regional board within six milliseconds of the first impact.

"They're going to scrub the trucks, Dad," Marcus said, his professional composure cracking just enough to show the dry panic underneath. "They’ll bury the logs, blame an uncertified human operator in the adjacent lane—which happens to be you—and they’ll rewrite the corridor permissions by midnight. If that core has grandfather’s name on it, they’ll say the system was compromised by outside interference. By us."

"Then we’d better get to San Simon first," Silas said simply.

"In what?" Marcus gestured wildly at his Ford interceptor. "This thing has a factory transponder that reports my GPS every five seconds to the dispatch desk. I can't drive two miles off-corridor without triggering a remote kill switch on the battery packs."

Silas grinned, the wrinkles around his eyes bunching up into deep, leathered folds. He tapped the brass tire thumper against his palm and nodded toward the idling Peterbilt.

"You’ve spent twenty years telling me that old Cat three-forty-six belongs in a museum, Marcus. You said it was too loud, too dirty, and used too much diesel. But there isn't a transponder on that frame that wasn't put there with a half-inch lock washer, and there isn't a line of code between the front bumper and the pintle hitch that can be reached by a satellite."

Marcus looked at the towering green Peterbilt, its long hood stretching out like a freight train, then back down at the sleek, ruined shell of the Titan four.

"Ben," Marcus said into his radio. "Can you mask my interceptor’s transponder?"

"For about eight minutes," Ben’s voice came back instantly. "I can cycle the diagnostic loop so it looks like the car is stuck in an automated reboot sequence behind the crash site. After that, the sector supervisor is going to dispatch a drone from the Benson relay tower."

"That gives us ten miles," Marcus said. He looked at Silas. "Can that dinosaur do eighty?"

Silas snorted, turning his back on the wreck and walking toward his cab. "Son, back in seventy-nine, your granddaddy drove this rig from Barstow to the El Paso yard in nine hours flat with a load of wet produce. She won't just do eighty. She’ll do it while shaking the fillings out of your corporate teeth."

Marcus hesitated for a single heartbeat, looking down at his tablet. On the screen, a new notification appeared—a red-bordered message flashing from Logistics Corp Central Security: CORRIDOR 10 WEST ANOMALY CONFIRMED. ASSET RECOVERY TEAM EN ROUTE. TERMINATE ALL UNLICENSED TELEMETRY.

With a sudden, sharp motion, Marcus pulled the corporate device from its mount, dropped it onto the broken asphalt, and brought his leather heel down hard on the glass face. The screen splintered with a dull pop, the amber lights winking out forever.

"Get in," Silas yelled down from the open door of the Peterbilt. "Before that electronic leash of yours figures out where you left your spine."

Marcus climbed up the high steps, his polished city shoes slipping slightly on the knurled metal, and pulled himself into the passenger side of the cab. The interior was like stepping back into nineteen-seventy-five: dark brown vinyl, a forest of analog gauges with needles that wobbled on bronze pins, and the dry, sweet scent of warm oil and coffee grounds.

Between the two air-ride bucket seats, a heavy floor-mounted shifter rose toward the roof, capped with a faded red skull containing an old gear-pattern coin.

Silas didn't waste time with a pre-trip check. He reached out with his left hand, dropped the heavy parking brake knob with a loud pssshh-clack of discharging air, and slid the sixteen-speed transmission into low-forward with a smooth, effortless clunk that told of forty years of synchronized wear.

The massive diesel engine took a deep gulp of the thin desert air. As Silas rolled into the throttle, the Peterbilt pitched slightly to the right under the massive torque of the flywheel, its mechanical injectors hammering with a steady, rhythmic violence that vibrated right through the floorboards and into Marcus’s shins.

They pulled away from the crash site, their tires grinding through the debris of the high-tech wall that had separated the old world from the new. In the wide side-mirrors, Silas watched the ruined silver pods grow smaller—carcasses of a future that had tried to run before it knew where the road went.

"Ben," Silas barked at the dashboard CB unit. "You still on the wire?"

"I’m here, Grandy," Ben said, his voice now coming through the short-range radio unit Silas had patched into the overhead speaker. "I just tapped into the state highway camera at the San Simon bypass. The gate isn't abandoned."

Silas didn't take his eyes off the road. He shifted into fifth gear, the transmission singing its high, whine of straight-cut gears. "What’s there, boy?"

"There are six Titan units parked in the old turnaround loop," Ben said, his voice dropping an octave. "They aren't crashed. They're idling. They're running their engines on minimum cycle, parked in a perfect circle facing inward, like cows in a blizzard."

"And the gate?" Marcus asked, leaning over the console.

"The gate was cut open twenty minutes ago," Ben replied. "With a torch. An oxygen-acetylene rig. There’s an old Ford pickup parked by the pumphouse. Grandy... the registration on that pickup came back cleared from the state database twelve years ago. It belonged to Ezekiel Vance."

Silas didn't shift. He held the engine at three thousand revs, the roar of the Cat filling the cabin until the glass in the wing vents rattled.

"That truck was crushed for scrap in ninety-six," Silas said, his voice dead level. "I watched the baler drop on it myself at the yard in Wilcox."

"Then someone rebuilt it from the iron up," Ben said. "Because it's sitting on the scale right now, and the automated plate reader just logged it as active."

Silas reached down, pulled the road-ranger splitter up with his thumb, and kicked the Peterbilt into high-nine. The long green hood rose as the turbo spooled, blowing a clean plume of grey smoke toward the empty blue sky above the Peloncillos.

Behind them, far back on the western horizon, three small black dots rose from behind the canyon rim. They weren't buzzards. They were high-altitude Logistics Corp patrol drones, their quad-rotors cutting the thin air as they swept the road for missing property.

"Marcus," Silas said without turning his head.

"Yeah?"

"Reach under the sleeper bunk. Pull out that canvas roll behind the breaker box."

Marcus reached back, his fingers feeling along the grease-varnished plywood of the bunk floor until they hit the coarse fabric of an old military-surplus tool roll. He dragged it out. It was heavy, tied with greasy rawhide thongs, smelling of cosmoline and ancient floor sweepings.

"Open it," Silas commanded.

Marcus untied the knot. Inside, nestled between half-inch drive sockets and open-ended wrenches that looked large enough to service a locomotive, was a heavy steel toggle box with three brass switches and an analog aviation gauge marked in kilocycles.

"What is this?" Marcus asked.

"That's what your grandfather used when the government men wanted to test if their ghost wagons could handle an electronic storm," Silas said. "He called it the Rattlesnake. He built it out of a radar-jamming unit he bought off an Air Force master sergeant in Alamogordo back when people still traded military hardware for six cases of Coors."

Marcus looked at the crude wiring, the hand-soldered resistors, and the heavy lead wire running down through the floorboards to an antenna bolted to the Peterbilt’s chassis frame.

"Silas," Marcus said, his voice rising in alarm. "If this thing broadcasts on the frequencies I think it does, it won't just scramble the drones. It’ll trigger an emergency stop on every autonomous vehicle within five miles. It’ll blind the whole corridor."

Silas looked in the mirror at the black dots dropping down out of the heat haze, their camera pods swiveling as they locked onto his license plate.

"Then they’d better learn how to use their brakes," Silas said. "Flip the first two switches, son. Let’s see if that old iron still has its rattle."
