The radio console on the dash of Deputy Tess Gentry’s Ford Explorer had a habit of popping whenever the engine climbed above thirty miles an hour. It wasn't a standard mechanical failure so much as a localized ghost, one of those tiny irritations you learned to ignore if you wanted to survive a twelve-hour patrol shift in Blackwood County without grinding your back teeth down to chalk. Tess tapped the plastic housing with the blunt end of a yellow ballpoint pen, listened to the static settle into a low, dry hiss, and turned off the paved state route onto the washboard gravel of Ridge Road.

Early October in the northern corner of the state did not bring the postcard colors people put on calendars. It brought a stubborn, slate-gray damp that soaked the underbrush and turned the gravel roads into cold oatmeal. The trees up here were mostly dense, choking hemlock and scrub pine, black against the dull sky, their branches knitting together over the road until daylight felt like something viewed through dirty aquarium glass.

Tess adjusted her collar against the draft whistling past the driver’s-side window gasket. She had been on the road with the Sheriff’s Department for exactly four months, which was long enough to know where the washouts were on every county artery, but not quite long enough to stop feeling the heavy, unearned weight of the brass star pinned to her wool uniform shirt. Before taking the job, her mother had warned her that wearing a uniform in the county where she’d grown up would make people treat her like either a trespasser or a babysitter. So far, her mother had been entirely right.

The dash unit squawked again, clearing its mechanical throat before the dispatcher’s voice broke through.

"Unit Four, Blackwood."

Tess lifted the heavy mic from its cradle. "Four. Go ahead, Marge."

"Tess, got a call from the state park trailhead up near Mile Marker Nine on Ridge. Caller states an unattended vehicle has been sitting past the overnight limit. Three days now, according to the logging crew that works the back parcel."

"Three days?" Tess glanced at the odometer, calculating the distance. Mile Marker Nine put the turnout near the northern edge of the park boundary, right where the timber holdings abutted federal land. "Park service didn't tag it?"

"Park service has two seasonal rangers covering four hundred square miles until the weekend shift comes in," Marge replied, her voice crackling with the dry fatigue of someone who had operated Blackwood County’s emergency dispatch board since the Carter administration. "Ranger Davies is down in town dealing with an illegal burn behind the lumber yard. It’s on us. Owner is registered out of county. A blue Subaru wagon. Call came in from Hank Miller over at Miller Logging. He says it’s blocking the turnout where they swing their tri-axles."

"Ten-four. I'm about two miles south on Ridge now. I'll swing by and check the plate."

"Copy, Four. Take your time. Hank’s been yelling since six this morning, so another twenty minutes won’t sour him any worse than he already is."

Tess clipped the mic back into place and eased her foot down on the accelerator. The Explorer shuddered as the tires caught a patch of rippled mud, the rear end drifting a few inches toward the ditch before the traction control seized the wheels and straightened the frame. Hank Miller was not a man known for patience. If Hank had an empty log truck stuck behind an out-of-towner’s station wagon, he had likely already threatened to push it into the gorge with a skidder.

The road wound upward, following the spine of the ridge that gave the route its name. To the left, the ground dropped off into a sharp, moss-slicked ravine known locally as Dead Man’s Creek—an imaginative piece of 19th-century naming that applied to about four different bodies of water in the county. To the right, a sheer shale bank rose twenty feet into the pines, weeping cold groundwater onto the gravel.

Tess was twenty-four, lean and sharp-shouldered, with dark hair tied into a braid so tight under her patrol cap it felt like a mild headache. She had done two years of criminal justice coursework down at the state university before her father’s hip replacement had brought her home to help run the hardware store on Main Street. When the county advertised an opening for a road deputy, her father had pushed the clipping across the kitchen table. Better than stocking galvanized nails for the next thirty years, he had said. Sheriff Clint Vance had hired her on the spot, mostly because he had played high school football with her uncle and knew she could shoot a rifle without closing both eyes.

She rounded a sharp dogleg around a stand of birch trees and spotted the commotion before she saw the cars.

Two logging trucks—huge, rattling Western Stars with yellow cabs caked in gray river silt—were idling in the middle of the road, their diesel exhaust puffing thick white plumes into the cold air. Leaning against the hood of the lead truck was Hank Miller himself, clad in an orange safety vest that strained against a belly hard-earned over decades of diner breakfasts and sitting behind a steering wheel. He was waving his arms at a small blue station wagon parked haphazardly half-in and half-out of the narrow graveled turnout.

Tess rolled the Explorer up behind the log trucks, flipped on her amber advisories, and climbed out into the wind. The cold hit her instantly, smelling of wet rotting pine needles and diesel fumes.

"About time, Gentry," Miller hollered, his voice carrying over the rumble of the six-hundred-horsepower engines. "I got sixty tons of green pine behind me and three more rigs coming down the cut. Some city idiot decided this was an overnight campground."

"Morning, Hank," Tess said, stepping around a puddle of rust-colored water. She adjusted her duty belt, which still felt too stiff around her hips. "You don't need to yell. The trucks are loud enough."

"I yell because I’m losing fifty dollars an hour sitting on this hump," Miller said, spitting a dark stream of tobacco juice onto the bumper of his rig. "Tow the damn thing. Shove it over the bank for all I care. The boy who parked it walked off toward the ridge trail on Tuesday. My skidder operator saw him."

"Tuesday was three days ago," Tess said.

"That's what I told dispatch. Boy had a backpack big enough to hold an apartment, wearing those bright orange hiking boots. Looked like a walking catalog." Miller shook his head with disgust. "The ground up top is freezing at night. If he’s still up on the bench, he’s either an idiot or an icicle."

Tess left Miller grumbling and walked toward the Subaru. It was an older Outback, covered in the fine, powdery dust that came from driving twenty miles on washboard roads, its rear hatch adorned with college parking permits and an environmental society sticker. She touched the hood with the back of her gloved hand. It was dead cold. A layer of wet pine needles had accumulated in the trough between the windshield and the hood, decaying into a soft brown mat that suggested the car hadn’t moved since the heavy rain two nights prior.

She pulled her small leather notebook from her breast pocket and took down the plate number, then walked a slow circle around the perimeter.

Through the rear passenger window, she peered into the back. A cardboard box of non-perishable groceries sat on the folded-down seat, mostly granola bars, dry pasta, and gallon jugs of spring water. An empty nylon sleeping bag compression sack lay crumpled on the floor mat beside a pair of dry, muddy trail runners. On the front passenger seat rested a road map of the state forest, spread open and creased along the northern quadrant, with a yellow highlighter line tracing a path from the Ridge Road trailhead up toward the High Divide.

Beside the map was a university student ID card.

Tess leaned in closer, shielding the glare off the glass with both hands. The card bore the blue-and-gold seal of the state college. The photo showed a young man, probably twenty-one or twenty-two, with wiry brown hair and wire-rimmed glasses that slid slightly down the bridge of his nose. The name printed below read: Julian Keller.

She backed away from the car, walked over to the edge of the turnout, and looked at the trailhead marker. It was a weather-beaten wooden post with a routed trail name painted in peeling yellow: Hogback Ridge Loop – 14 Miles. A metal box for hiker registration was nailed to the post, its hinged lid rusted shut. Tess pried it open with her pocketknife, pulling out a waterlogged spiral notebook.

The last entry was dated Tuesday morning, 7:15 AM.

J. Keller. Out-and-back to the High Divide. Return expected Wednesday 5 PM.

Today was Friday, nearly ten in the morning.

Tess unclipped her radio mic. "Four to Blackwood."

"Go ahead, Tess."

"Run a plate for me, Marge. State plate: Golf, Kilo, X-ray, four-one-nine. Also run a name query: Julian Keller. K-E-L-L-E-R. Should be a student down at the university."

"Stand by, Four."

Hank Miller walked over, his heavy boots crunching on the stone. He pulled off his knit cap and scratched a bald, shiny head. "Well? You calling the wrecker or what? Roy’s garage is forty minutes out, and my drivers have log tickets waiting at the mill."

"He's two days overdue, Hank," Tess said, not looking at him. She was staring at the woods behind the trail marker. The timber here was dense, a thick tangle of rhododendron and second-growth hemlock that choked the light within twenty yards of the shoulder. A narrow footpath wound between two large mossy boulders, slick with fallen leaves and dead fern fronds. "I'm not towing it yet. If he walks out of those woods with hypothermia and finds his car gone, he's in worse trouble than you are with your delivery schedule."

"He ain't walking out," Miller muttered. "It dropped to twenty-eight on the mountain Wednesday night. We had sleet up at the high camp."

"Let's hope he had a tent," Tess said.

The radio buzzed, cutting through the low hum of Miller’s complaints. "Four, Blackwood. Plate comes back to Julian Keller, age twenty-two, registered address in Greenfield. I ran his name through the campus safety liaison. His roommate called him in missing about two hours ago. Said Keller went out for a solo field study on some soil samples and hasn't shown up for his lab shift."

Tess felt the skin on the back of her neck tighten. A car abandoned because of engine trouble or a weekend bender was typical county business; an overdue student on a mountain that was currently freezing at night was a real problem.

"Understood, Marge. Contact the Sheriff. Tell him we've located the vehicle at the Mile Nine turnout on Ridge Road. The car's locked, cold, and the logbook has him overdue by forty-eight hours."

"Sheriff’s at the county building in town for the commissioners' budget meeting," Marge said. "He told me not to pull him out unless the courthouse was actively burning down."

"Tell him anyway," Tess said flatly. "And notify Search and Rescue to put a preliminary team on standby. The Hogback trail crosses federal ground after mile three. If he drifted off the bluffs, the search area is going to be a nightmare."

"Copy that, Four. Stand by at the vehicle."

Tess pocketed her notepad and looked back at Miller. "Hank, you can squeeze your trucks past him if you take the ditch side slow. There's eight feet between his bumper and the shoulder drop."

Miller scowled, looking at the narrow margin between the station wagon and the steep shale drop-off on the other side of the road. "If my rear tandems slip that ditch, Tess, your uncle is going to hear about it."

"If your rear tandems slip, I'll pull you out with the winch," Tess said without breaking her stride as she walked past him toward the Explorer. "Now get moving so I can keep the road clear for emergency traffic."

Miller grumbled, spat again, and climbed back into the cab of his Western Star. Within two minutes, the trucks were grinding their gears, their huge, knobby tires churning the mud as they squeezed carefully past the parked Subaru, their diesel fumes hanging heavy in the damp mountain air before slowly drifting up into the pines.

Once the sound of the logging trucks faded down the mountain, the silence that settled over Ridge Road was absolute.

It was the specific kind of silence that belonged only to the high forest in autumn—no birds, no insects, just the faint, continuous hiss of the wind moving through the tops of the white pines thirty feet overhead. Tess pulled her heavy winter jacket out of the back of the patrol vehicle, zipped it up to her chin, and walked back over to the Subaru.

She took her flashlight from her belt and shone the beam into the interior again, checking the floorboards, the glove box, and the ignition. Nothing seemed out of place. The keys weren’t hidden in the wheel well—she checked all four—and the vehicle wasn't damaged. The hiker had simply parked, locked up, and walked into the dark green canopy.

Ten minutes later, the unmistakable gravel-crunch of a heavy truck signaled company.

A white Chevrolet Silverado with the county emblem on the door pulled into the turnout, spraying a small arc of muddy water against the Subaru’s rear quarter panel. The driver’s door opened with a long, ungreased creak, and Sheriff Clint Vance stepped down.

Vance was fifty-eight years old, with broad, thick shoulders that carried the weight of thirty years of county politics and three decades of diner coffee. His uniform jacket was unbuttoned, revealing a tie that was slightly crooked against his khaki shirt. He wore a brimmed felt hat pulled low over eyes that had seen too many lost hunters, too many domestic disputes, and entirely too many school board meetings.

He didn't look happy.

"Marge pulled me out of the finance committee," Vance said by way of greeting, stepping over the ditch with a heavy, deliberate pace. "The commissioners were five minutes away from approving our new patrol cruiser allocation, and I had to walk out because a college kid couldn't figure out a trail map."

"Julian Keller, Sheriff," Tess said, keeping her tone completely neutral. "Overdue since Wednesday afternoon. His car's been sitting here three days. Weather up top hit twenty-eight two nights ago."

Vance walked around the Subaru, tapping the rear glass with his wedding band. He peered inside, just as Tess had done, his expression hardening into the familiar, weary grimace he reserved for tourist problems.

"Greenfield kid?" Vance asked.

"University student. Geology or forestry, looks like. Notebook says he went up to the High Divide."

"The High Divide is five thousand acres of scrub oak, loose shale, and old logging cuts," Vance said, turning his back on the car to look up at the mountain. "Half of it isn't even mapped right because the state timber survey hasn't been updated since ninety-eight. If he broke an ankle up in the rock piles, he could be in any one of twenty different draws."

"Search and Rescue can stage at the ranger station down at the foot of the grade," Tess suggested. "If we get twenty ground volunteers and some dogs, we can push up the main trail before dark."

Vance took off his hat, wiped his forehead with the back of his forearm despite the cold, and settled the hat back in place. "Ground team takes four hours to mobilize, Tess. By the time Dave gets the volunteer fire boys out of work, gets the gear loaded into the trailers, and brings them up Ridge Road, the sun’s going to be behind the mountain. We'd be walking them into the dark on wet shale. That’s how you turn one missing person into three."

"We can't just leave him up there for another night, Clint," Tess said, dropping the official title for a second. "Another night below freezing, and we're not looking for a hiker. We're looking for a recovery."

Vance sighed, his jaw working as he looked at the dense, impenetrable wall of dark spruce that flanked the road. The timber was so thick that even fifty yards in, the forest floor was lost in murky shadows.

"I know," Vance said quietly. "I know that, Tess."

He walked back to his truck, opened the passenger door, and reached into the cab. When he emerged, he wasn't carrying a map or a handheld radio. He was carrying a heavy, black, hard-plastic Pelican case, roughly the size of a large suitcase, reinforced with steel corners and locked with heavy yellow latches.

He carried it over to the hood of Tess’s Explorer and dropped it down with a solid, echoing thud.

Tess looked at the case, then at Vance. "What's that?"

"That," Vance said, flicking the latches open with an irritated snap, "is our new budget line item. The state homeland security liaison dropped it off at the substation two weeks ago. Some university tech grant program for rural search operations."

He lifted the lid.

Inside, nestled in custom-cut charcoal foam, was a piece of equipment that looked entirely foreign against the muddy backdrop of the Blackwood County timber. It was an unmanned aerial vehicle, but not the small, plastic quadcopters Tess had seen hobbyists fly over the park fields. This machine was nearly three feet across, constructed from matte-black carbon fiber, with six folding arms, heavy, broad rotor blades, and a gimbaled sensor ball mounted underneath that held two distinct lenses: one high-resolution optical camera, and one large, dark lens that looked like an oversized eye.

Beside the frame lay three massive brick-like battery packs, a ruggedized field tablet with sunshades, and a controller fitted with heavy toggle switches and an external antenna array.

Tess stared at the apparatus. "The autonomous aerial unit? You said at the staff meeting we weren't going to deploy that until the training rep came down from the capital next month."

"The training rep is currently sitting in a hotel room in Denver," Vance said sourly. "And Julian Keller is currently sitting somewhere on the Hogback freezing to death while the county commissioners decide whether they want to pay for our gas."

He pointed a thick finger at the equipment.

"You took those systems integration courses down at the college, Tess. You spent two years playing with computer-aided mapping and telemetry software before you decided you wanted to carry a Glock and write speeding tickets. Can you get that thing in the air, or am I calling the state police to ask for a helicopter they won’t send until tomorrow morning?"

Tess looked at the matte-black carbon arms, the complex wiring tucked neatly into the central housing, and the sleek screen of the tablet. She felt a strange, cold flutter in her chest—not fear, exactly, but the sharp focus that came when theory collided head-on with a cold mountain and an empty trail.

"I can fly it," Tess said.

Vance nodded once, his expression completely blank. "Then set it up. We’ve got about four hours of gray light left, and Julian Keller has already used up all his luck."

The Pelican case smelled like machine oil, ozone, and factory-fresh neoprene. Tess lifted the heavy, hexacopter frame by its central spine, surprised by how light the carbon fiber felt despite its sprawling wingspan. It was an uncanny kind of lightness—the sort engineered into expensive composite archery bows and aerospace gear, built to withstand tremendous torque while weighing hardly more than a wet winter coat.

Sheriff Clint Vance leaned against the hood of her cruiser, his hands buried deep into the pockets of his fleece-lined canvas jacket. He watched her work with the quiet, skeptical scrutiny common to rural lawmen who still preferred paper carbon forms over touchscreen terminals. "There’s a three-ring binder under the lid," Vance grumbled, nodding toward the case. "Looks like half an encyclopedia. You need to read the safety protocols, or does your university diploma cover that?"

"The diploma covered aeronautical physics and signal routing, Clint," Tess said, not looking up as she snapped the six folding arms into their locked positions with satisfying metallic clicks. "The binder is just boilerplate legal disclaimers so the state doesn't get sued if we decapitate a turkey vulture."

She set the drone on the gravel bed between the two vehicles, away from the mud and low brush. The machine stood on two arched carbon skids, its dual-lens sensor turret hanging beneath the nose like the eye of an enormous mechanical dragonfly. She slotted the primary lithium-polymer battery into the dorsal bay. The contacts met with an audible spark, followed by a sequence of rising electronic tones as the internal flight computers booted. A ring of high-intensity status LEDs around the motor hubs blinked red, cycled through amber, and settled into a steady, predatory blue.

Tess retrieved the ground station controller from the foam insert. It was built into a ruggedized Pelican shell of its own, featuring twin joystick gimbals flanked by an array of heavy-duty toggle switches, rubber-shielded directional pads, and an ultra-bright ten-inch tablet screwed directly into the frame. She flicked the master power switch. The screen flickered, displaying the county seal for two seconds before cutting straight to the proprietary flight telemetry suite: AeroScout Tactical OS – Build 4.12.

"Satellites?" Vance asked, squinting over her shoulder at the display.

"Acquiring," Tess murmured. "Five... eight... twelve. We’re locked. Differential GPS is green. Barometric altimeter calibrated to local ground level." She pulled out the antenna masts, angling them forty-five degrees outward. "The grant program didn't buy a toy, Clint. This thing has an internal terrain-following radar and active lidar collision avoidance. As long as I keep the uplink alive, it won't let me fly it into a tree even if I try."

"Trees aren't what worry me," Vance said, his voice flat. "Losing a thirty-thousand-dollar piece of state hardware on day one is what worries me. The county commission would have my hide tacked to the courthouse door."

Tess ignored the warning and tapped through the initialization menus. A live video feed popped up on the left half of the display. The camera was pointed down at the gravel; she could see the scuffed toes of her duty boots and Vance's mud-caked Red Wings in razor-sharp high definition. The optical feed was so crisp she could count the individual threads on her trouser hems. On the right side of the screen, a digital topographic map of Blackwood County populated, drawing elevation contour lines over the Hogback Ridge loop and marking their current position with a pulsing green crosshair.

"Julian Keller's route goes east along the creek, up through the hemlock stand, then cuts back west across the bench toward the High Divide," Tess said, tracing the route on the glass with her gloved fingertip. "If he stayed on the blazed path, he’s somewhere within this four-mile corridor. If he twisted an ankle or got disoriented when that freeze rolled in on Wednesday, he probably dropped into the lee of the ridge to get out of the wind."

"Or he fell off the Rim," Vance added grimly. "There are three hundred vertical feet of sheer drop on the east face. You slip off that wet sandstone, you don't stop until you hit the boulders in the bottom of the gorge."

"Let's hope he had more sense than that," Tess said. She stepped back from the drone, holding the controller securely against her chest with the harness strap. She toggled the arming switch.

The six large carbon-fiber propellers twitched, completed a self-calibration sweep, and then spun up with a deep, authoritative hum. The wash from the blades instantly cleared a three-foot circle of dead pine needles and fine gravel, whipping the hem of Tess's jacket against her holster. Hank Miller's muddy tire tracks dried under the sudden blast of air.

Tess eased the left stick forward.

The drone didn't wobble or drift. It broke contact with the earth with unnatural smoothness, climbing straight up into the gray autumn sky like an elevator on invisible rails. Ten feet, fifty feet, a hundred feet. The aggressive buzzing of the rotors softened into a distant, hornets'-nest whine, swallowed by the vast silence of the mountain canopy.

By the time the altimeter read two hundred and fifty feet above ground level, the aircraft was nothing more than a tiny black cross against the overcast sky. Tess shifted her eyes entirely to the monitor.

The perspective was dizzying. Blackwood County opened up beneath the lens in a sprawling, muted mosaic of dark hemlock, yellowing birch, and wet slate rock. Below them, Ridge Road was a thin, rust-colored thread carved through the timber, with her patrol Explorer and Vance's white Silverado looking like matchbox cars parked beside the blue speck of Keller’s Subaru. Beyond the road, the land crumpled upward into the wild, jagged spine of Hogback Ridge, stretching north toward thousands of acres of uninhabited state timber reserve.

"Good picture," Vance admitted, his tone softening with reluctant approval. "Better than the view from the fire tower."

"Watch the telemetry," Tess said, pushing the right stick gently forward. "We're heading northeast along the trail corridor. Speed is twenty knots. Heading zero-four-zero."

The drone banked smoothly, its camera gimbal compensating so perfectly that the horizon on screen remained utterly level. The forest floor rushed beneath the sensor in a blur of mossy green and wet bark. The Hogback trail was barely visible from this altitude—a faint, intermittent scratch winding through the dense canopy, frequently vanishing beneath the interlocking boughs of old-growth white pines.

Tess flipped a rubber-coated toggle on the top left of the controller. "Switching to sensor fusion. Optical on the main view, thermal overlay at thirty percent."

The image on the tablet shifted. The natural colors faded into muted shades of cool blue and violet, while any heat source was immediately highlighted in vibrant yellow and white. Down on the road, the hood of Vance's idling pickup glowed like an open furnace. A pair of white-tailed deer resting in a brushy hollow two hundred yards off the trail showed up as bright, glowing embers through the thin birch canopy, their body heat radiating clearly through the chilly mountain air.

"Thermal's working," Tess said, feeling a surge of quiet confidence. "If Keller is out there and his core temp is anywhere near normal, he’ll light up this screen like a roadside flare."

"And if he’s hypothermic?" Vance asked.

"He'll still be warmer than wet sandstone," she replied, keeping her eyes glued to the glass. "The ambient temperature is thirty-eight degrees. Even a cold body gives off enough infrared radiation to trigger the contrast algorithm."

They flew in silence for five minutes, the drone eating up distance that would have taken a ground searcher an hour of agonizing, knee-deep bushwhacking to cross. Tess piloted the craft along the primary trail switchbacks, methodically scanning each ravine and drainage cut. The wind was picking up along the ridge crest; the telemetry display showed the drone fighting a fifteen-knot crosswind, its automated flight controller tilting the rotors to maintain an unerringly straight search grid.

They passed Mile Marker Two of the footpath, where the trail climbed over a series of wet shale steps known as the Devil’s Staircase. Tess dropped the altitude to one hundred and twenty feet, leaning the camera downward to peer through the gaps in the timber.

"Nothing on the steps," Tess reported. "Trail is washed out in two places from Wednesday's storm. Lots of loose scree. If he went up that way, he was slipping."

"Keep going toward the High Divide," Vance directed, pointing a blunt finger at the northern quadrant of the digital map. "There’s an old forestry shelter near the four-mile marker. Stone hut built by the Civilian Conservation Corps back in the thirties. Roof is half-caved, but if the boy had any wilderness survival training, that's where he'd hole up to wait out the sleet."

Tess adjusted their bearing, banking the hexacopter toward the northern shoulder of the mountain. The terrain below grew steeper, wilder, and distinctly more forbidding. The deciduous trees gave way almost entirely to dense stands of black spruce and hemlock, their thick, year-round boughs forming a near-solid roof that blocked the optical camera from seeing the forest floor.

"Can't see the ground through this timber," Tess said, tapping the thermal sensitivity up to maximum gain. "The foliage is too thick. I need an opening."

"There's a natural clearing just below the shelter," Vance said. "A granite outcrop where the timber thins out. Get over that and angle the sensor back toward the shelter entrance."

Tess pushed the sticks forward, accelerating the drone to thirty knots to conserve battery. The power gauge in the upper corner of the screen read sixty-two percent. With the heavy headwind and the cold air degrading cell capacity, she calculated they had about twelve minutes of usable flight time left before the craft's automated failsafe would force a return-to-base sequence.

The granite outcrop slid into view on the tablet. It was a massive, barren dome of gray stone, slick with recent rain, jutting out from the mountainside like the curve of an ancient skull. Just beyond it, tucked into a dense copse of stunted spruce trees, sat the CCC shelter. It was built from dry-stacked river rock, its cedar-shingle roof sagging heavily under years of neglected snow loads.

"There it is," Vance said, leaning in so close his stale tobacco breath washed over Tess's cheek. "Drop down. Let's see if anyone's home."

Tess eased the throttle back. The drone descended smoothly, dropping through the freezing air until it was hovering just forty feet above the granite clearing, its rotors buffeting against the swirling mountain wind. She brought the camera around, centering the lens on the shelter’s low doorway.

The interior of the stone hut was pitch black on the optical feed, but the thermal sensor painted the interior walls in deep, icy indigo.

"Nobody," Tess said, a heavy knot of disappointment settling into her stomach. "Interior is dead cold. Ambient temperature throughout. If someone was inside that hut in the last twelve hours, the rocks would still hold a residual heat signature. It's empty."

"Damn it," Vance muttered. "Kid must have lost the trail before he ever reached the ridge."

Tess didn't pull back on the sticks immediately. She panned the camera slowly in a three-hundred-and-sixty-degree circle around the stone hut, looking for any sign of human disturbance—a discarded pack, broken branches, footprints in the wet moss. There was nothing. Just the indifferent, primeval wilderness, dripping with cold mist.

Then, at the very edge of the screen, something flickered.

It wasn't inside the shelter, and it wasn't on the established trail. It was nearly two hundred yards northwest of the clearing, deep inside an area marked on the county map as an unmaintained, off-limits timber easement. The canopy there was brutally dense, but through a small natural gap between two dying white pines, the thermal sensor caught a bright, distinct splash of crimson.

Tess froze the camera gimbal. "Clint. Look at the upper left corner."

Vance squinted, pulling a pair of wire-rimmed reading glasses from his pocket and perching them on his nose. "What is that? A deer?"

"Too hot for a deer," Tess said, her fingers dancing across the touchscreen to zoom the optical lens to four-times digital magnification. "And it isn't moving. An animal moves, shifts, feeds. This is a static thermal plume. It’s radiating at nearly ninety degrees."

"A camp stove?" Vance asked, his brow furrowing. "Did he make camp out in the brush?"

"Only one way to find out," Tess said.

She pitched the drone forward, sending it skimming over the tops of the spruce trees toward the heat anomaly. The wind hit the craft harder as it cleared the shelter ridge, the control sticks vibrating slightly in her hands as the flight software compensated for the sudden turbulence. The battery meter dropped to forty-eight percent. A yellow warning indicator flashed in the status bar: HIGH WIND ADVISORY - REDUCE CRUISE VELOCITY.

Tess ignored the warning. She hovered the drone directly over the gap in the trees and tilted the camera straight down at a ninety-degree angle.

At first, the optical view showed only layers of dark, wet branches, glistening needles, and rotting forest floor. But as she brought the sensor down to eighty feet, the downwash from the powerful hexacopter blades began to peel back the upper boughs of the spruce, parting the evergreen curtain like a curtain drawn on a stage.

The thermal plume wasn't coming from a campfire. And it wasn't Julian Keller.

Tess stared at the screen, her heart suddenly thumping against her ribs.

Sitting in a narrow, unmapped hollow between two steep shale cuts was an idling vehicle. It was a heavy-duty pickup truck, painted in flat, non-reflective olive drab, completely stripped of any commercial badges or license plates. Its engine block and exhaust manifold glowed brilliantly on the thermal display, radiating the fierce, distinct heat of an internal combustion engine that had been running within the last ten minutes.

"What the hell is that?" Vance whispered, his voice suddenly sharp and tense. "There are no logging roads in that drainage. That cut was abandoned by the paper company back in the seventies."

"Someone cleared a path," Tess said, her voice dropping. She zoomed the lens in further. Through the blown-apart branches, she could see fresh, deep tire tracks cutting through the wet moss, crushing young saplings under heavy, aggressive mud-terrain treads.

Beside the idling truck stood a metal equipment crate, painted in the same matte olive finish, its lid thrown open on heavy hinges. Resting against the rear tailgate of the truck was an orange nylon internal-frame backpack—bright, clean, and unmistakable.

"Clint," Tess said, her voice trembling slightly. "That pack. Hank Miller said Julian Keller was wearing an orange pack."

Vance reached out and gripped the edge of the controller, his knuckles turning white. His eyes were wide, fixed on the screen with an expression Tess had never seen on the older man's face before—not worry, not bureaucratic annoyance, but a cold, sudden dread.

"Pull it back, Tess," Vance said. The words were quiet, but they carried the sudden weight of an iron door slamming shut.

"Wait, there might be someone in the cab," Tess insisted, reaching to toggle the thermal camera to full resolution. "If Julian's hurt in that truck, or if someone—"

"I said pull it back!" Vance barked, his voice cracking like a rifle shot across the quiet mountain turnout. He reached out and forcefully tapped the controller's automated return-to-launch button.

The screen flashed: RTH INITIATED.

Above them, high over the mountain canopy, the drone pivoted sharply on its yaw axis and began its automated flight back toward the GPS coordinates of the turnout.

Tess stared at the Sheriff, stunned by the sudden violence in his voice. Vance stood rigid beside her cruiser, staring up into the gray sky where the distant whine of the rotors was slowly growing louder. His face was completely drained of color, his jaw clenched so tightly that the muscles in his cheek were twitching.

"Clint," Tess said, her voice steady but demanding. "That truck isn't on any county registry. It was running. And that was Keller's gear sitting on the tailgate."

Vance didn't look at her. He pulled his hat down lower over his forehead and stared out at the dark, silent wall of timber that bordered Ridge Road.

"Pack the machine away, Deputy," Vance said, his voice entirely devoid of the easy familiarity he had used only ten minutes earlier. "We're going back to town. Now."
