The basement of the Oregon State Police forensic annex smelled of vinegar, ozone, and forty years of floor wax applied over damp concrete. It was three floors below the daylight and two doors down from the boiler room, which made it ten degrees warmer than the rest of the building in winter and almost unbearable by mid-August. A handwritten placard, taped to the frosted glass of the entrance with yellowing masking tape, said Missing and Unidentified Persons Section. Someone with a black Sharpie had crossed out Section and written Graveyard Shift.

Detective Silas Thorne did not mind the heat, but the humming ballast of the fluorescent light directly above his desk had given him a dull headache every workday since 2011. He reached up with the rubber tip of an unsharpened number-two pencil, tapped the metal housing twice until the flicker steadied, and went back to the ledger.

It was an actual ledger, bound in scuffed oxblood buckram with brass-reinforced corners, measuring eighteen inches across when open. It predated the National Missing and Unidentified Persons System by three decades, predated CODIS by longer than that, and predated the internet entirely. It had been started during the Johnson administration by a clerk named Mrs. Hattie Vance, who had possessed impeccable Palmer-method penmanship and an institutional horror of untied ends. Every time a hunter stumbled across a femur in the Tillamook, or an angler hooked a sneaker containing three metatarsals out of the Columbia River, Mrs. Vance had dipped her steel-nib pen into Higgins India ink and given the dead an accession number.

Thorne ran his index finger down the margin of page seventy-four.

The entry read: Case 1984-U-0114. Remains recovered October 12, 1984, timber access road 4N, south slope of Saddle Mountain, Clatsop County. Female, estimated 18–24. White or Hispanic. Cause of death: blunt force trauma to cranium with post-mortem burning. Clothing remnants: blue denim weave, brass snap labeled 'Scovill', synthetic fiber scraps (red/black). No teeth present (post-mortem extraction). No jewelry. Fingerprints: unobtainable. Status: Unidentified.

Beneath the entry, three different investigators had signed their initials over the course of four decades. The most recent set was dated September 1999, followed by the pencil note: STR profile unsuccessful due to severe thermal degradation. STR kit exhausted. Box 44-B transferred to shelf 9.

"She’s been sitting on shelf nine since the Clinton administration, Silas," a voice said from the doorway.

Thorne didn't look up immediately. He finished copying the case accession number onto a fresh yellow legal pad. "Shelf nine is dry," he said. "Dry is good for petrous bones. If she were in the annex at Eugene, she’d have had black mold growing on her occipital plate twenty years ago."

Dr. Vivienne Ramos pushed the door open with her hip. She was balancing two paper cups from the drive-through coffee hut down on Commercial Street, one of which had already leaked brown grease through its seam. Ramos was thirty-two, half-Filipino, had a doctorate in biological anthropology from Knoxville, and held a title that the State of Oregon classified as Forensic Technical Specialist III, which meant she did the work of three senior medical examiners for seventy percent of the pay.

She set the dry cup in front of Thorne. "Black, two sugars, lukewarm. Just how you pretend to like it."

"I don't pretend," Thorne said, picking up the cup. "Hot coffee scalds the taste buds. You can't taste the chicory."

"There is no chicory in drive-through diner coffee from Salem, Silas. There is only caffeine and regret." Ramos pulled the second chair away from the map table and sat down, resting her chin on her palm. She looked at the red buckram volume. "Why the '84 case? The lieutenant specifically told us to clear the backlogged NamUs verifications for the 2010 runoffs before the fiscal audit."

"Lieutenant Miller is at an administrative seminar in Sunriver until Thursday," Thorne said mildly. "He believes that if we verify dental charts for six living runaways who turned out to be tending bar in Joshua Tree, the unit looks productive for the legislative budget subcommittee. He is probably right."

"And you?"

"I think the living runaways can wait until Thursday afternoon to have their paperwork stamped. The girl on Saddle Mountain has been on shelf nine for fourteen thousand, three hundred and ninety-two days." Thorne closed the ledger with a dull thump that stirred a minute puff of gray dust from the binding. "And the lab in Salt Lake just notified me that they pulled twelve nanograms of usable nuclear DNA from the petrous wedge we cut in June."

Ramos sat up straighter. Her professional cynicism, which she wore like a heavy woolen coat even in the summer, slipped for a second. "Twelve? From that sample? The cranium was cooked like charcoal. When we took the saw to the temporal bone, I thought we were going to get nothing but ash and machine grease."

"Twelve nanograms," Thorne repeated. "They ran it through the new high-throughput sequencing platform twice. Library preparation worked. We have a whole-genome sequence, Vivienne. Six hundred thousand single-nucleotide polymorphisms."

"SNPs," she murmured, using the field's universal shorthand. "Not just sixteen short tandem repeats for a CODIS hit that never comes."

"Not CODIS," Thorne said. "No felon database. No waiting for some state trooper in Idaho to pull over a seventy-year-old man with a busted taillight and a warrant. We have the whole map. We just need to find out where her cousins went to school."

He stood up, reached for his windbreaker on the coat peg behind the door, and took down a ring of heavy brass keys. Thorne was fifty-one years old, a retired county homicide detective who had spent twenty-five years looking at bodies that still had wallets in their pockets, driver’s licenses in their visors, and names that could be yelled across a kitchen table by weeping mothers. In those days, homicide was a matter of momentum: who saw the car, who bought the shells, who was seen arguing near the gravel pit at two in the morning.

When his knees gave out on patrol work and the department offered him a desk in the state’s newly cobbled-together Cold Case Genetic Genealogy Project, he had expected it to be a quiet pasture where old cops went to read microfiche until their pensions kicked in. Instead, he had found the ledger.

There were eight hundred and forty-two unidentified bodies in the State of Oregon alone. Men who had jumped from the Vista Bridge in 1973 with their coat tags snipped out; loggers crushed by Douglas firs in the high Cascades whose bunkmates only knew them as 'Frenchy' or 'Red'; newborn babies found in cardboard grocery boxes along the Willamette sloughs; and young women—always young women—left naked under blackberry bushes along logging spurs thirty miles from the nearest paved county highway.

To the state, they were property numbers. To the budget analysts, they were an ongoing storage fee paid to the state university’s anthropology locker or the dry shelves of the Salem annex. To Silas Thorne, they were an insult.

"Where are we going?" Ramos asked, though she was already getting up.

"Shelf nine," Thorne said. "I want to look at the teeth again."

"Silas, the file says there are no teeth. The killer took them out with pliers to prevent identification from dental records. It’s right there in the county coroner’s notes from eighty-four."

"Coroner’s notes were taken by Doc Henderson," Thorne said, stepping into the dim hallway. "Doc Henderson was seventy-one years old in 1984, he ran a family practice out of his basement in Seaside, and he hated doing autopsies because they made his arthritis flare up. He wrote 'no teeth present' because the sockets were empty. I want to see if they were empty before she went into the fire, or after."

The storage room was fifty yards down a concrete corridor that ran beneath the parking lot. The air here was cooler, chilled by the dampness of the surrounding earth, and smelled of cardboard and desiccated bone.

Row upon row of heavy industrial steel shelving stretched into the darkness, each bay labeled with a decade and a quadrant of the state. White archival boxes, each roughly the size of a pair of men's work boots, sat three to a shelf, numbered with black grease pencil. There were hundreds of them. A city of the nameless, organized by filing convention.

Thorne walked down aisle four without looking at the overhead placards. He had the geography of the room memorized. He stopped at bay twelve, reached up to the third shelf, and took down Box 84-U-0114.

It was lighter than a layman would expect. An entire adult skeleton, once cleaned of moisture, fat, and soft tissue, weighs barely twenty pounds. A skeleton that has been through a brush fire and thirty-nine years of dry air weighs considerably less.

He carried the box back to the examination table in the center of the room—a massive slab of stainless steel with a perimeter drain that hadn't been hooked up to water since 1994. He flipped the light switch, bringing two overhead surgical lamps to life with a dry hum.

"Get the caliper," Thorne said.

Ramos went to the metal tool cart, retrieved the sliding digital caliper and a pair of blue nitrile gloves, and snapped them onto her hands. She handed a pair to Thorne, who put them on slowly, smoothing the rubber down over his large, blunt-tipped fingers.

He lifted the lid of the box.

Inside, nestled in acid-free tissue paper that had yellowed around the folds, were the fragments of Case 1984-U-0114.

The long bones were arranged at the bottom: femurs, tibiae, the slender shafts of the fibulae. They were gray-brown, the color of weathered driftwood, with dark, longitudinal cracks where the intense heat of the fire had shrunk the organic matrix faster than the mineral structure could contract. The skull sat at the head of the box, resting in a donut-shaped ring of polyethylene foam.

It was incomplete. The left parietal was missing entirely, shattered by the blow that had killed her, and the edges of the remaining bone were beveled inward—the classic signature of a heavy, blunt impact with a radiused edge. A tire iron, Doc Henderson had written. Or the poll of a small woodsman's axe.

Ramos leaned over the steel table, her dark eyes scanning the maxillary arch.

"Look at the alveolar process," Thorne murmured, his face three inches from the charred bone. "Henderson said extraction. If somebody pulls fourteen teeth out of a living girl, or even a girl who died five minutes ago, what happens to the bone?"

Ramos frowned, tilting her head to catch the rake of the overhead light. "The margins of the socket fracture. Even with dental forceps, you get splintering of the buccal plate. Especially on the premolars and the canine roots. Canines don't just come out clean; their roots are an inch long and anchored like fence posts."

"And here?"

Ramos took a stainless probe from her pocket and gently traced the empty, scalloped edge of the upper jaw.

"The bone isn't broken," she said softly. Her voice dropped the flippant tone it had held in the office. "The margins are rounded. Smooth. Look at the canine sockets—there's remodeling here, Silas. This isn't post-mortem extraction."

"No," Thorne said.

"This is congenital anodontia. Or severe, full-mouth extraction that happened months—maybe years—before she died. The sockets are half-absorbed. She didn't have her teeth knocked out by a killer in the woods. She didn't have them when she arrived."

Thorne picked up the pad of paper and a pen. "Henderson didn't know the difference between alveolar resorption and post-mortem trauma. He saw an empty jaw on a burnt skull and assumed the monster who did it was trying to hide her identity. So for forty years, the troopers were looking for a missing girl with a great smile whose dental charts would match a missing persons file."

"While she," Ramos said, looking down at the small, fragile arc of the jaw, "probably wore an upper denture from the time she was sixteen. Or she walked around with a mouth that she kept her hand over every time she laughed."

"People remember that," Thorne said. "A girl eighteen years old with no upper front teeth. In 1984, that wasn't common. Not even in the logging camps."

He looked at the skull's empty orbits. The bone was thin, paper-dry, and fragile as an eggshell. On the shelf behind them, hundreds of other boxes sat in the low light, each holding some variation of the same silence. A man found in the Sandy River with three links of chain wrapped around his pelvis. A child's skull found in an apple crate behind an abandoned barn in Woodburn. A torso found in a burn pile near the Santiam Pass that had been listed only as Subject Twelve since the year Mount St. Helens blew its top.

Every one of them had a family tree. Every one of them had two parents, four grandparents, eight great-grandparents, cascading back through the centuries in an unbroken geometric progression of human blood and coupling. You could burn a body until the fingerprints vanished; you could smash the teeth with a ball-peen hammer until there wasn't a cusp left to compare to a dental card; you could throw the body into a ditch in the Coast Range and let forty years of pine needles and winter rain melt the flesh into the topsoil.

But you couldn't get rid of the sequence.

Every cell in her bone contained the ledger of everything she had ever been, and everything her ancestors had been since they stepped out of the forests of Europe or crossed the Bering land bridge. It was written in the four-letter alphabet of her nucleotides, sixty thousand times longer than the King James Bible, stamped into every fragment of the petrous wedge currently sitting on an ice block in a private genomics lab six hundred miles to the south.

"Who do we have on the DNA?" Ramos asked.

Thorne turned away from the box and looked at the dry-erase board on the far wall of the basement. The board was divided into three columns: Laboratory, Tree, and Field.

Under Laboratory, there were six cases listed. Four of them were red-flagged for 'Insufficient Quantity' or 'High Bacterial Contamination'—the common fates of bodies left in the wet coastal rain forests, where soil microbes eat human DNA for breakfast. But next to Case 1984-U-0114, the ink was fresh and blue.

"The extract went to GeneSearch in Salt Lake," Thorne said. "They did the bait capture on Monday. The raw data file came in at four this morning. I sent the compressed text file to Maeve."

Ramos let out a low whistle. "Maeve's working it? I thought she was still buried in that sixty-year-old case from Klamath Falls."

"The Klamath Falls case ended yesterday," Thorne said.

"Identified?"

"Identified. It was an itinerant sheep shearer from Basque country who walked away from a work camp in November of 1958. His grand-niece is a paralegal in Boise. She had her DNA on an open-access platform because she wanted to find out if her great-grandfather really came from Guernica." Thorne wiped his thumb across the dry-erase board, clearing a small space under the second column. "Maeve cleared the tree in three days once she realized the family changed their name from Etxebarria to Berry when they hit the sheep ranches in Malheur County."

"And this one?" Ramos gestured toward the box. "What did the Salt Lake run look like?"

"Three million SNPs mapped. High confidence. Maeve says the girl is primarily Northwest European—about sixty percent British Isles, thirty percent German, with a trace of Scandinavian down on the maternal line. But there's a match. A real one."

Ramos stepped closer to the board. "How close?"

"Two hundred and ten centimorgans."

Ramos was quiet for a second, doing the mental math. In the new language of their work, centimorgans were the currency of belonging. They weren't years or miles; they were the measure of shared genetic material, the physical length of the chromosome segments that two people had inherited from the same man and woman. A parent and child shared three thousand four hundred. Siblings shared about two thousand six hundred. A first cousin was eight hundred.

"Two hundred and ten," Ramos said. "That’s... second cousin once removed? Or a third cousin?"

"Could be a second cousin once removed," Thorne said. "Could be a half-second cousin. Or a great-great-aunt, if we were dealing with somebody ninety years old, which we aren't. It's enough to find the great-grandparents. If the tree doesn't hit a brick wall in the 1900 census, Maeve thinks she can give us a surname by Friday."

He walked over to the box, took the lid, and set it gently back over the skull of the girl from Saddle Mountain. He didn't use tape; you never taped an evidence box if you were going to be back in it before the week was out.

"Saddle Mountain is rough country," Ramos said, staring at the brown cardboard. "Even now, with the state park trails, you get off the fire road three hundred yards and it’s all devil's club, sword fern, and deadfall. In 1984, that was all Crown Zellerbach timberland. Gated roads. You didn't just wander up there with a sedan and dump a body. You had to have a key to the timber gates, or you had to have a four-wheel drive with a winch and a reason to be out there in the fog."

"A logger," Thorne said.

"Or a hunter. Or a local kid who knew where the crews parked the skidders." Ramos pulled her gloves off with a sharp snap of rubber against skin. "You think whoever put her there is still around?"

"The county had sixty thousand people in 1984," Thorne said. "Half of them worked wood, the other half worked fish. If he was twenty-five then, he’s sixty-five now. He’s sitting on a porch in Astoria or Warrenton, drawing an IWA-PMA pension, watching the log ships head out over the Columbia bar, and thinking nobody is ever going to come down his gravel driveway."

"And if he’s dead?"

Thorne picked up the yellow legal pad where he had written the number 1984-U-0114. He carefully folded it once and put it into his breast pocket, next to his pen.

"Then I’ll tell his children what he did," Thorne said.

He turned out the examination lamps, leaving the room once more in the dim, gray gloom of the basement. They walked back down the aisle between the high steel shelves, their shoes clicking against the sealed concrete.

Outside the storage room, the hallway was silent except for the low, rhythmic thumping of the old steam radiator at the far end of the hall, like a heart that hadn't quite realized the rest of the body had stopped moving forty years ago.

Thorne reached his office door, took the brass key from the lock, and stepped inside.

On his desk, the computer monitor was glowing with the blue-and-white interface of the genealogy database. A new message was waiting in his inbox from an address labeled M.Lindholm_Consulting.

The subject line was five words long:

Saddle Mountain: Found the branch.

Thorne pulled his chair out, sat down, and reached for the cold coffee. He didn't tap the fluorescent light fixture this time; he simply leaned toward the screen, clicked the mouse, and began to read.

The road to Saddle Mountain had changed in forty years, but only in the way a face changes under the influence of slow, indifferent violence. What had been a gravel-slick logging spur maintained by heavy-duty graders in the autumn of 1984 was now a deeply rutted trench of red clay and basalt ballast, choked at the margins by alder saplings and the sprawling, thorny runners of Himalayan blackberry.

Silas Thorne kept the Ford Crown Victoria—a heavy, rear-wheel-drive relic the state police refused to decommission because its oil pan was virtually bulletproof—in low gear. The engine whined, a high-pitched protest against the fifteen-degree incline, while the undercarriage scraped against a high center of wet shale.

"The county surveyor told me this road was decommissioned in ninety-six," Ramos said, holding onto the passenger-side grab bar with both hands. Her knuckles were white against her dark skin. "By 'decommissioned,' I think he meant he dropped a three-ton boulder across the entrance and hoped everyone would forget it existed."

"They did forget," Thorne said, his eyes locked on the narrow track between the trees. "Except for the mushroom hunters. And the people who need to dump three hundred pounds of drywall where the county code enforcement officers can't find them."

He swung the steering wheel hard to the left, dodging a deep wash where a plugged culvert had routed a small, brown creek directly down the center of the roadbed. The Ford lurched, its solid rear axle bouncing off the rock wall, before settling back into the mud with a wet slap.

They were five miles north of Highway 26, climbing the southern shoulder of the ridge that led to the summit. Below them, visible only through brief gaps in the dense canopy of second-growth Douglas fir, the Clatsop Plains stretched out toward the gray line of the Pacific. It was a landscape defined by water: water in the air as a thick, salty mist that smelled of rotting spruce needles; water in the soil that turned every footprint into a miniature pond within ten seconds; water in the wood that made even the standing timber look black and bruised.

Thorne pulled the car onto a narrow shoulder where the road widened slightly before ending at a rusty steel gate. The gate was locked with a heavy brass padlock that had turned green with lichen, though someone had cut the chain-link fencing on the right-hand side to allow dirt bikes through.

"This is the four-north access," Thorne said, cutting the ignition. The sudden silence of the forest was heavy, broken only by the steady, metallic tick-tick-tick of the cooling manifold and the soft, rhythmic patter of condensation dropping from the high branches onto the car's roof. "In eighty-four, Crown Zellerbach was logging the south slope. They had three sides running up here. Eighty men, six yarders, and thirty log trucks a day coming down this spur."

Ramos let go of the grab bar and rubbed her palms against her jeans. "How did the hunter find her?"

"He wasn't hunting," Thorne said, opening his door. The damp air hit him immediately, smelling of cold mud and the sweet, slightly rotten scent of elderberry. "He was looking for his dog. A three-year-old blue tick hound that had chased a mountain beaver into the brush. The dog didn't come back when he whistled, so he went in after it. He found the dog digging under a rotten hemlock log about forty yards off the grade."

He walked to the trunk, popped the lid, and pulled out a pair of tall rubber boots and a bright orange surveyor's vest. Ramos did the same, her boots squeaking against the wet gravel as she stepped into the ditch.

From the backseat, Thorne retrieved a thick leather-bound folder containing the original 1984 case file. The paper inside was thin, yellowed around the margins, and smelled faintly of the old wood-smoke heating system they used to have in the Astoria sheriff's substation before the county rebuilt it in the late nineties. He flipped to a hand-drawn map, sketched in black ballpoint pen on grid paper by a deputy named Arnie Miller—the uncle of their current, vacationing lieutenant.

The map was simple, almost primitive. It showed the logging spur, the gate, and a small, hand-drawn X labeled Body found here. The distance from the road was marked as 130 feet, bearing 210 degrees SW from double-topped cedar.

"The double-topped cedar is probably gone," Ramos said, squinting into the dense wall of green that rose from the edge of the ditch. "In forty years, a tree like that either gets wind-thrown or choked out by the firs."

"We'll find the stump," Thorne said. "Or the log. Trees don't go far when they die up here. They just lie down and wait for the moss to cover them."

He climbed over the cut section of the chain-link fence, his boots sinking three inches into the soft peat of the forest floor. Ramos followed, carrying a small canvas pack containing a handheld GPS unit, a digital camera, and a roll of orange flagging tape.

The transition from the open roadbed to the timber was immediate and cold. The light dropped by half under the thick canopy, leaving the forest floor in a green, sub-aquatic twilight. Giant sword ferns, their fronds six feet long and dripping with water, brushed against their chests as they pushed through. Beneath the ferns lay a chaotic tangle of fallen branches, rotting stumps from the first logging run in the nineteen-twenties, and thick mats of moss that hid deep holes between the root wads.

Thorne moved slowly, his eyes scanning the ground. He had spent his youth in these woods, hunting blacktail deer with his father and later searching for lost hikers with the search and rescue teams. He knew the grammar of the forest—how a straight line in the brush usually meant an old skid road, how a sudden patch of pale green alder marked a place where the soil had been cleared by a slide or a bulldozer thirty years before.

"Here," he said, stopping beside a massive, moss-covered mound that rose like a green whale from the forest floor.

Ramos caught up to him, her breath coming in short, white puffs. "A stump?"

"The double-topped cedar," Thorne said. He reached down and scraped away a thick layer of wet moss with his gloved thumb, revealing the dry, red wood beneath. The top of the stump was hollow, a deep basin filled with brown water and rotting needles, but the trunk had split into two distinct, parallel columns before it had been cut. "Miller's map was right. The road was closer then—they must have widened the ditch when they put the gate in."

He took a small brass compass from his pocket, held it flat in his palm, and turned until the needle settled on two hundred and ten degrees.

"One hundred and thirty feet," he said, pointing through a dense thicket of salmonberry bushes whose brown, woody canes were covered in small, sharp thorns. "That way."

They began to push through the briars. The thorns hooked into Thorne's heavy canvas jacket, making a dry, scratching sound that seemed loud in the damp silence of the ridge. The air grew heavier as they descended into a small, marshy draw where a spring seeped out from the basalt layers of the mountain.

In 1984, the county coroner had estimated the body had been in the woods for three to six months before it was found. That meant she had been placed here in the late spring or early summer, during the dry weeks when the logging crews were working double shifts to beat the August fire closures.

"Silas," Ramos said from behind him. "Look at the canopy here."

Thorne stopped and looked up. Above them, the trees were younger—slender, pale alders and small hemlocks that had grown up in a narrow, rectangular corridor about twelve feet wide.

"An old skid trail," Thorne said. "Where they dragged the logs down to the landing."

"Which means whoever brought her here didn't have to carry her through the brush," Ramos said. She pointed to a low, rotting log that lay across the draw. "They could have backed a truck or a small tractor right down this alley from the road. In eighty-four, this would have been clear of brush. Just bare dirt and wood chips."

"And mud," Thorne added. "If it was June, the mud would have been knee-deep in this draw. A regular passenger car would have bottomed out in five yards."

He reached the spot marked on the old map. It was a shallow depression behind the hemlock log, now completely filled with sword ferns and a thick, green carpet of wood sorrel. The hemlock itself was nearly gone, reduced to a long, red mound of punky wood that crumbled like wet cake when Thorne pressed his boot against it.

This was where she had lain for those three months, hidden from the road by the bulk of the log, while the sun climbed over the ridge and the summer rains beat down through the hemlock needles.

Thorne sat down on a dry spot on the fallen trunk, his knees clicking in the cold. He looked down at the hollow where the body had been.

"The original report said she was partially buried," he said. "Not with a shovel. Just covered with loose bark, branches, and a piece of old green tarp."

"The tarp was gone by the time they found her," Ramos said, sitting down beside him and opening her notebook. "The mice had chewed most of it up for nests. But they found fibers—green polyethylene—in the leaf litter."

"And the fire?"

"It was local," Ramos said. "The killer didn't try to burn the whole woods—that would have brought the forestry planes down on him in ten minutes. He piled dry cedar limbs over her midsection and used some kind of accelerant. Probably diesel or kerosene from one of the logging skidders. It didn't burn long enough to consume the long bones, but it did enough damage to destroy the soft tissue on her torso and scorch the skull."

Thorne nodded, his eyes fixed on the empty earth. "He wanted to destroy her face. He knew who she was, and he knew that if anyone found her before the winter rains came, they'd recognize her."

"But he didn't count on the dog," Ramos said.

"No. He didn't count on the dog."

Thorne reached into his pocket and pulled out the printout of the email he had received from Maeve Lindholm before they left the office. The paper was already damp from the air, the black ink of the family tree beginning to spread slightly at the edges.

"Maeve’s tree is centered on a family named Sterling," Thorne said, tracing a line on the paper with his finger. "They were homesteaders in the Nehalem Valley back in the eighteen-eighties. Had six sons and three daughters. By nineteen-forty, there were Sterlings in Vernonia, Jewell, Birkenfeld, and half the small mill towns between here and Portland."

"Our match is two hundred and ten centimorgans," Ramos said, leaning over to look. "That means she's a great-grandchild of one of those nine original siblings."

"Actually, it's more specific than that," Thorne said. "Maeve found the common ancestor. A man named Thomas Sterling, born in 1894. He was a donkey doctor—the guy who repaired the steam hoisting engines for the big timber outfits. He had four children with his wife, Martha. Two boys, two girls. All of them are dead now, but they had children of their own."

He pointed to a small, handwritten box at the bottom of the page, circled in red ink.

"One of Thomas's daughters, Evelyn, married a man named Donald Vance in 1948. They lived in Astoria. Donald was a commercial fisherman—fished for salmon on the river, did some crabbing in the winter. They had three daughters. Two of them are still living in the area. One of them, Clara, is sixty-eight. She lives in a trailer park behind the Safeway in Warrenton. The second, Donna, is seventy-two. She's in an assisted living facility in Longview."

"And the third?" Ramos asked.

"The third was named Margaret," Thorne said. "Born in 1964. The family called her Peggy. According to the school records Maeve pulled from the county archive, Peggy Vance stopped attending Astoria High School in March of 1982, during her junior year."

Ramos looked from the paper to the shallow, green depression in the earth. "Did anyone file a missing persons report?"

"No," Thorne said. "And that's the part that keeps me cold."

He stood up, his boots squelching in the mud, and walked to the edge of the old skid trail. He looked up toward the gate, where the faint white roof of the Crown Victoria was just visible through the alders.

"In nineteen-eighty-two, the county was in the middle of the timber crash," Thorne said, his voice flat. "The mills were closing down one after the other. People were packing up their trucks in the middle of the night and driving to California or Texas to look for work. If a seventeen-year-old girl with a bad mouth and a history of running away didn't come home for dinner, her father didn't call the sheriff. He assumed she'd hitched a ride south with one of the construction crews or gone to live with her aunt in Tacoma."

"But she didn't go to Tacoma," Ramos said.

"No," Thorne said. "She came up here. Or someone brought her."

He walked back to the hemlock log, reached into his pocket, and took out a small plastic specimen bag. Inside was a single, small brass snap, its surface covered in a green layer of copper oxidation. It was the "Scovill" snap mentioned in the 1984 coroner's report, the only piece of her clothing that had survived both the fire and the four decades of wet rot.

"They found this near her left hip," Thorne said, holding the bag up to the dim green light. "It's from a pair of blue denim overalls. The kind they sold at the Montgomery Ward in Astoria for six dollars in 1981."

Ramos stood up, her face pale in the shadow of the hemlocks. "Silas. If she's Peggy Vance, we have more than a name."

"We have a family," Thorne said. "And we have a home."

He turned back toward the mountain road. The wind was picking up, rattling the dry alder leaves overhead and sending a fresh shower of cold rain down through the spruce needles. It was the same rain that had fallen on Saddle Mountain on the night she died, the same rain that had washed her blood into the red clay of the skid trail, and the same rain that had kept her secret for fourteen thousand days.

But the secret was leaking now, dissolving like the hemlock log under their feet.
