A mule will kill a man out of malice, but an honest horse will only do it because his teeth ache.

Arthur Phelan considered this truth every time he stuck his right arm past a pair of yellowing incisors up to his rolled-up shirtsleeve. Most men in the New Mexico Territory in the dry spring of 1883 put their faith in Colt revolvers, church on Easter Sunday, or the Santa Fe Railroad, but Arthur pinned his mortal survival on the temper of a heavy brass mouth-speculum and the sharp edge of a twelve-inch float. If the leather strap slipped or the hinge pin sheared, twelve hundred pounds of gristle and bone would clamp down on his knuckles like an iron bear trap. It made for a quiet, attentive kind of life.

The horse currently contemplating whether to take Arthur’s fingers off was a liver chestnut gelding belonging to a freighter named O’Shea. They stood behind the stage depot on the southern fringe of Mesilla, where the dust was ankle-deep and smelled of stale dung, axle grease, and creosote baking in ninety-degree heat. The beast was braced on three legs, his head hoisted high in a hemp twitch held tight by O’Shea’s Mexican hand, a boy named Cruz who looked as though he would rather be standing in the path of an oncoming locomotive.

"Easy, you red devil," Arthur muttered, keeping his voice level as an irrigation ditch. He ran his calloused left hand up the bridge of the horse’s nose, pressing his thumb into the soft hollow behind the nostrils to encourage a swallow. "Hold him steady, Cruz. If he throws his poll back, don't you pull against him. Just lean your weight into the stick."

Cruz nodded once, his dark eyes wide under the brim of a straw hat that had seen several rainy seasons too many. His knuckles were gray from gripping the oak handle of the twitch.

Arthur reached into his leather kit, which lay unbuckled over an empty flour barrel. The tools of his trade were neither elegant nor gentle, though he kept them oiled and free of rust with tallow and emery cloth. There were straight-handled floats for the lower molars, guarded angular rasps for reaching the sharp enamel points along the upper cheek teeth, heavy extraction forceps forged by a gunsmith in St. Louis, and a set of bone chisels that looked like they belonged in a timber-framer’s chest. He selected a forward-canted rasp with a coarse diamond-cut face.

"What's he doing that made you send for me, O'Shea?" Arthur asked without looking around.

The freighter, a square-faced man with a ginger beard gone salted with alkali dust, was leaning against the wheel of a high-sided Murphy wagon, shaving tobacco off a black plug with a thumb-worn pocketknife.

"Quidding his hay," O'Shea said, his voice like gravel turning in a wooden chute. "Drops half his corn on the ground like a hog with no manners. When I put the bit to him three days back to pull out for El Paso, he reared up and damn near broke the wagon tongue. Figured he'd gone rogue. I was ready to put a round behind his ear and buy another at the pens, but horseflesh is dear this season."

"Cheaper to spend two silver dollars on me than forty on a green bronc," Arthur said.

"That remains to be seen. You haven't done nothing yet except talk sweet to him and unpack your ironware."

Arthur didn't bother to answer. He had heard the same skepticism from Dodge City to Chihuahua. Most frontiersmen thought a horse was a machine made of leather, bone, and stubbornness, repaired only with a whip or a bullet. They didn't understand that a horse's cheek teeth grew continuously throughout its life, worn down unevenly against each other until the outer edges of the upper molars turned into rows of razor-sharp shears. When a teamster pulled on the reins, those razor points pressed the tender flesh of the cheek right into the iron, slicing the mouth to ribbons. A horse fighting the bit wasn't always mean; often as not, he was just being butchered from the inside out.

Arthur caught the horse’s tongue with his left palm, slipping it out through the interdental space—the bar of the mouth where no teeth grew—and holding it to the side. The chestnut gave a wet, shuddering snort, showering Arthur’s brown duck trousers with green-tinged froth, but the tongue out of alignment kept the beast from clamping his jaw shut. Arthur slid two fingers along the inside of the left cheek.

He felt the rough enamel instantly. The fourth premolar on the upper jaw had formed a sharp hook that had carved a deep, festering ulcer into the tender pink lining of the cheek. Arthur’s fingertips came away smeared with bloody slime and foul-smelling gray matter.

"He's not rogue," Arthur said, reaching for his rasp. "He's got a spur on his upper jaw long enough to hitch a mule to. Every time you jerk that line, you're driving a chisel into his cheek."

"Can you smooth it?" O'Shea asked, pocketing his knife.

"I can take it off. Hold him, Cruz."

Arthur brought the rasp up, slipping the hooded steel head along the roof of the mouth until the teeth caught the metal. He set his feet, leaning his shoulder into the chestnut’s jaw to anchor himself, and went to work.

The sound was terrible. It was the dry, grinding screech of hardened steel biting into dense calcified bone, a noise that resonated through the horse's skull and set Arthur’s own molars on edge. Skrrt-ch-skrrt. Skrrt-ch-skrrt. The gelding groaned deep in his chest and lunged forward, nearly lifting Cruz off the ground. The boy clung to the twitch, the horse's upper lip twisted white and bloodless under the tight hemp cord, cutting off his wind just enough to keep his brain occupied with staying upright.

"Steady," Arthur grunted. Sweat broke out across his forehead, stinging his eyes beneath the sweatband of his battered felt hat. He kept his strokes long, even, and deliberate. You couldn't hurry a float. If you slipped, you tore the palate; if you bore down too hard, you cracked the root and set up an abscess that would rot the jaw clean through by midsummer.

He worked the upper arcade from front to back, knocking off the jagged points, then traded the straight rasp for an angled one to reach the very back molars where the cheek gathered tight against the hinge of the jaw. With each pass of the tool, white powdery bone dust fell out of the horse’s lips, mixing with the lather and blood on Arthur’s forearms.

After ten minutes of rhythmic labor, the sound changed from the harsh scrape of jagged peaks to a flat, dull slide. Arthur pulled the iron free, washed it in a bucket of cloudy well water, and reached back in with his bare fingers to inspect the work. The razor edges were gone, replaced by a smooth, beveled surface that felt like river-rounded limestone.

"Let the twitch off, Cruz," Arthur said.

The boy loosened the stick, untwisting the cord from the chestnut’s lip. The gelding stood trembling, his neck stretched out low, licking his lips with a hollow, rhythmic clacking sound as he tasted the blood and bone dust in his throat. He did not rear, nor did he strike. He simply blinked his dark, liquid eyes and blew a long, rattling breath that scattered the dirt between his hooves.

Arthur wiped his hands on a greasy rag, then reached into his vest for a small plug of sweet licorice root he kept for himself. He broke off an inch and fed it to the horse. The gelding took it cautiously from his open palm, rolled it back to his molars, and chewed without flinching.

"Look at that," O'Shea murmured, coming closer and staring at the beast's mouth as if it were a parlor trick. "He ain't drooling it out."

"He won't fight the bit tomorrow either," Arthur said. "Give him soft bran tonight. No dry grain till the ulcer heals up, and don't haul on his mouth like you're hauling a bucket out of a mine shaft. He's got feeling in his head, same as you."

O'Shea dug a heavy leather purse from his canvas trousers, untied the thong, and fished out two silver dollars. He pressed them into Arthur's palm. The silver was cool against Arthur’s heat-flushed skin, stamped with the liberty head and the year 1879.

"You're a strange sort of mechanic, Phelan," O'Shea said, neither kindly nor unkindly. "Most men out here look to take a horse apart with a skinning knife. Don't see many carry tools just to keep 'em chewing."

"There's more money in them living than dead," Arthur replied, rolling down his sleeves and buttoning the cuffs over his scarred wrists. "And less stink."

"Not by much," O'Shea grunted, looking down at Arthur’s blood-spattered boots. He turned to Cruz. "Get him watered and hitched to the trace. We're burning daylight, and that freight for Fort Selden won't walk itself up the river."

Arthur packed his kit with methodical care. Each float had its oiled pocket in the heavy canvas roll; the forceps went into the center pouch with the gum-lances and the wire snips. He rolled the canvas tight, buckled the twin straps, and hoisted the bundle by its hemp handle. It weighed thirty pounds, every ounce of it forged iron and seasoned hickory.

He walked out of the depot alleyway and into the bright glare of Calle Guadalupe.

Mesilla in 1883 was caught between two worlds, and none too happy about either of them. Ten years earlier, it had been the grand capital of the territory, the undisputed trade hub of the southern overland routes, where the Butterfield Overland Mail changed teams and the Mexican grandees held court in sprawling adobe compounds behind thick mud walls. But the railroad—the cold, unyielding iron of the Atchison, Topeka and Santa Fe—had bypassed Mesilla two years back, choosing instead the shallow flats of Las Cruces three miles to the northeast across the river.

The life was leaking out of the old town, but it was leaking slow. The adobe walls were still four feet thick, keeping the midday heat at bay with their silent, sun-baked mass. Cottonwoods lined the acequias, their pale leaves rattling in the dry wind that blew down off the Organ Mountains to the east. The mountains stood like a row of blue-gray spear points against the pale sky, jagged and barren, throwing sharp purple shadows across the desert floor as the sun began its long descent.

Arthur walked his horse, a high-withered buckskin gelding named Copper, toward the town square. Copper was not a handsome horse—his head was slightly too large for his neck, and he had an old wire-cut scar on his left hock—but his teeth were immaculate. Arthur floated them twice a year with the precision of an engraver, and as a consequence, the buckskin kept his flesh through hard travel and never fought the curb.

They stopped at the public trough near the corner of the plaza. While Copper dipped his muzzle into the green-filmed water, Arthur stood with one hand on the saddle horn, surveying the square.

It was quiet. A two-wheeled carretas loaded with dry mesquite firewood creaked past, drawn by a pair of oxen whose ribs showed like the ribs of an overturned boat. Under the portales of the dry-goods store, two elderly men in white cotton trousers sat on low rawhide stools, their hats pulled down against the glare, smoking corn-husk cigarillos and watching the dust settle.

Mesilla felt like an old hound dog sleeping in the shade, half-dead until somebody stepped on its tail.

"You the fellow with the tooth-chisels?"

The voice came from behind him, crisp and carrying the flat, clipped cadence of Texas.

Arthur turned without taking his hand off Copper’s neck. A man had stepped out from the shadow of the cantina across the way. He wore a gray wool coat despite the heat, unbuttoned to reveal a clean white linen shirt and a low-slung holster carrying a single-action Colt with smooth walnut grips. He was forty, maybe younger, with a clean-shaven jaw and eyes the pale, washed-out color of skimmed milk. A flat-brimmed plainsman’s hat sat square on his head, perfectly level, giving him the appearance of a schoolmaster who had taken up soldiering.

"I float teeth," Arthur said. "Among other things."

"Name's Miller," the man said, stopping five paces away. He didn't offer a hand, but his pale eyes flicked over Arthur’s kit, then to Copper’s mouth, then back to Arthur’s face. "Tom Miller. I manage horses for Don Manuel Armijo out at the San Rafael grant."

Arthur knew the name. Armijo was one of the old families who still held Spanish land deeds the American courts hadn't managed to carve into ribbons yet. He owned three thousand head of cattle, two thousand sheep, and some of the best blooded Kentucky stock that had ever survived the journey across the plains.

"What's the Don need?" Arthur asked.

"He's got a four-year-old thoroughbred stud he brought out from Louisville on the cars," Miller said. His voice was flat, matter-of-fact, but there was an edge beneath it that Arthur didn't quite care for. "Horse cost eighteen hundred dollars. Right now, he's off his feed, colicky, and biting at his own flanks like he's full of hornets. Won't let a bridle near him. Local farrier tried to pull a wolf tooth out of him yesterday with an iron crow-bar and near got his skull split open."

"A wolf tooth won't make a horse bite his flanks," Arthur remarked.

"I didn't say it did. I said the farrier was an idiot." Miller spat into the dust. "Don Manuel wants someone who knows what he's doing before the stud starves himself to skin and bone. He heard there was an itinerant man in town working on the freight teams. Said to fetch you."

"The San Rafael grant is eight miles south, out in the sandhills," Arthur said. "It's late in the day. By the time I get out there, it'll be dusk. Working on an eighteen-hundred-dollar stud in the dark with a lantern between your teeth is a good way to get killed."

"The Don has plenty of lanterns," Miller said. "And plenty of money. He pays five dollars for the job, and five more if the horse is eating oats by sunup."

Five dollars was two days' hard labor at the livery barns. Ten dollars was half a month's board and a pair of new boots. But Arthur looked at Miller’s pale eyes, then down at the clean ivory-handled knife tucked into the man's vest pocket, and felt the small, cold tightening in his stomach that had kept him alive through the mining camps of Colorado and the border towns of the Rio Bravo.

"Who's holding the horse?" Arthur asked.

"Me," said Miller. "And two vaqueros with riatas."

"Tell your vaqueros to leave the riatas in the tack room. You choke a high-strung stud with rawhide and all he learns is how to hate you." Arthur turned to Copper, checking the cinch with his fingers. "I'll need clean water, four clean towels, and a pint of pure alcohol if you've got it. Not mescal. Grain spirit."

Miller’s lips twitched slightly, something that might have been a smile if it had reached his eyes. "The Don drinks French brandy. You can wash your irons in that if you're proud."

"Water does fine for the irons. The spirit is for the stud's gums." Arthur swung up into the saddle. The leather creaked, familiar and comforting beneath him. The buckskin stepped out immediately, sensing the shift in purpose, his ears pricking forward. "Lead on, Mr. Miller. Let's see what kind of mess your farrier made."

They rode south out of Mesilla, leaving the shade of the plaza behind.

The road to the San Rafael grant followed the river valley for a mile before climbing onto the first low mesa of caliche and gravel. Down in the bottomlands, the fields of alfalfa were brilliant green, watered by the muddy brown pulse of the Rio Grande through a network of ditches dug by the ancestors of the men who worked them. But up on the mesa, the New Mexico desert took over completely: gray saltbush, spindly ocotillo reaching toward the blue sky like spiny fingers, and clumps of creosote that released their medicinal, resinous tang into the cooling evening air.

Miller rode a neat little claybank gelding that moved with a short, easy fox-trot. He didn't speak much, which suited Arthur. Men who talked too much on the trail were usually trying to hide what they were thinking, but men who said nothing at all were usually thinking about things they wouldn't want you to know. Arthur kept Copper three paces behind the claybank, out of kicking range, watching the way Miller sat his saddle.

The Texan didn't ride like a vaquero, who sat deep with long stirrups and loose shoulders. He rode with his weight forward, his heels down, and his hands low on the pommel—the cavalry seat. The Seventh, maybe, or one of the frontier regiments that had spent the seventies hunting Victorio and Nana through the Black Range.

"You've been in these parts long, Phelan?" Miller asked after three miles of silent dust.

"Couple of weeks," Arthur said. "Came down from Socorro through the Jornada."

"Tough ride."

"Dry ride."

"Not many men choose horse doctoring when they can handle a rifle," Miller noted. His eyes stayed on the road between his horse's ears. "Saw the way you handled that rasp behind the depot. You got hands like an artisan. Surprised you ain't working a trade in Denver or San Francisco."

"San Francisco has too many brick buildings," Arthur replied. "And Denver is full of lawyers and cold weather. A horse doesn't lie to you. If he's going to kick you, he tells you with his ears first. Men aren't that polite."

"No," Miller said softly. "They surely aren't."

They topped a low rise, and the San Rafael hacienda came into view.

It was larger than Arthur had anticipated. A long, low quadrangle of whitewashed adobe sat against a cluster of enormous cottonwoods that marked a natural spring. Beyond the main house lay a series of corrals made of stout cedar pickets laced together with rawhide, and beyond them, two large barns built of stone and squared timber—an astonishing luxury in a country where timber had to be hauled thirty miles from the mountains.

As they rode through the arched gate into the courtyard, the smell of woodsmoke and roasting chiles met them, mixed with the sharp, acidic tang of horse manure and damp straw. A dozen dogs—lean, yellow curs of mixed hound and mastiff—barked from the shadows of the portales until Miller hissed a single Spanish word that silenced them like a whip crack.

A man stepped out from the main door of the house. He was short, thick-shouldered, and dressed in dark woolen clothes cut in the old Mexican style, with silver conchos running down the outer seams of his trousers. He carried a silver-headed cane, though he walked without a limp. His face was round and pale, framed by a thick, dark mustache that fell past the corners of his mouth.

"Is this the man, Tomas?" the Don asked in English, his accent light and precise.

"It is, Don Manuel," Miller said, dismounting with the fluid ease of a man who spent ten hours a day in the leather. "Arthur Phelan. He fixed O'Shea's freight wheeler in Mesilla."

Don Manuel Armijo stepped down from the portal, his small, dark eyes measuring Arthur as he swung down from Copper. The Don didn't look at Arthur’s clothes or his boots; he looked at his hands. Arthur’s fingers were thick, but long and straight, stained with walnut oil and scarred across the knuckles from old cuts.

"The horse is my grandfather's gift to me," Don Manuel said. His voice was low, carrying the natural authority of a man whose family had owned land since the King of Spain gave it to them on sheepskin parchment. "He is named El Almirante. If he dies, I will be very displeased. If he lives, you will be well compensated. Come."

He turned and led the way toward the stone barn at the rear of the compound. Miller fell in behind him, and Arthur followed, carrying his leather kit by the strap.

Inside, the barn was dark, cool, and silent save for the sound of a heavy body shifting in the end stall. Two lanterns hung from the crossbeams, their yellow light casting flickering shadows against the stone walls.

A young vaquero stood outside the box stall, holding a lantern up to the iron grate. He looked pale and nervous. Inside the stall, standing in deep, clean wheat straw, was the most beautiful horse Arthur had ever seen in the territory.

El Almirante was a dark bay, nearly black, with four white socks and a star like an arrowhead between his eyes. He stood sixteen hands high, with the sloping shoulders and deep chest of a racehorse, but his neck was arched high and thick with the crested power of an entire stallion.

Yet he was in misery.

The horse's flanks were tucked up, his belly drawn tight like a greyhound’s. His coat was damp with cold sweat that made his bay hide gleam like wet slate in the lantern light. His ears were pinned flat against his skull, and his upper lip was drawn back in a perpetual snarl, revealing teeth that were flecked with red foam. As they watched, the stud swung his head violently toward his own right shoulder, biting viciously at the empty air, then dropped his nose to the straw and struck at the floor with his left foreleg, the iron shoe ringing loud against the hard caliche earth.

"Colic," Miller said behind Arthur. "I told the Don we ought to drench him with turpentine and lard."

"You do that," Arthur said, "and you'll kill him."

Arthur set his kit down on a corn bin and stepped up to the stall door. He didn't look at the horse's flank, nor did he look at his eyes. He looked at the jaw.

On the right side of the stallion’s face, right beneath the facial crest where the cheek teeth were seated, there was a swelling the size of a goose egg. It was hot—Arthur could see the vapor rising off the skin in the cool air of the barn—and the hair over it was standing on end. From the corner of the stud’s mouth, a thin, yellow fluid was dripping slowly into the straw, thick and smelling of rotten cabbage and old fish.

Arthur turned to the Don. "Who worked on him yesterday?"

Don Manuel’s face darkened. "A blacksmith from Las Cruces. He said the horse had a wolf tooth that was driving into the lower bar."

"He didn't pull a wolf tooth," Arthur said grimly. "He took a hammer and a cold chisel to an impacted second molar and smashed the crown off. The root is split right down into the jawbone, and the nerve is wide open to the air."

The Don looked at Miller, then back to Arthur. "Can you take it out?"

"It’s not a matter of taking it out with a pair of pliers," Arthur said. "It's splintered. If I leave a shard the size of a grain of sand in there, the jaw will abscess into the sinus cavity within three days. Then you won't have a horse; you'll have a carcass."

"What do you need?" Don Manuel asked.

"More light," Arthur said, unbuckling his kit and laying out the cold steel. "And I need three men who aren't afraid of dying. If this stud goes down in the stall, he’ll thrash himself to death. We have to keep him on his feet."

Miller stepped forward, unbuttoning his wool coat and tossing it over the rail of the stall. Underneath, his arms were corded with wiry muscle. "I told you I'd hold him, Phelan. Get your tools."

Arthur looked at the Texan for three seconds. In the dim lantern light, Miller’s pale eyes were entirely devoid of fear—or any other human feeling. He was a tool, just like the cold steel rasps in the canvas roll. Useful, hard, and dangerous if handled incorrectly.

"Get the halter on him," Arthur said. "And make sure the lead is double-rigged. We're going to see what kind of iron this horse is made of."

Don Manuel stepped back toward the barn door, his silver cane resting against his boot, watching the itinerant mechanic go to work with the cold detachment of a man who had seen many things broken, and very few put back together.

The operation lasted until the desert night had swallowed every trace of the sun’s orange fire behind the sharp teeth of the mountains.

It took forty minutes of methodical savagery to free the crushed bone. Arthur had worked with his shirt stripped to the waist, his shoulders slick with sweat and foul matter, kneeling in the straw while Miller held the stud’s head snubbed down to an iron ring in the barn's stone foundation. When the final splinter—a jagged wedge of enameled root three inches long—came loose with a wet, sucking pop, the great stallion had shuddered from poll to tail, exhaled a rattle of exhaustion, and sunk quietly onto his knees.

Arthur had packed the cavity with linen lint soaked in the Don's French brandy, stitched the torn margin of the cheek with heavy waxed cobbler's thread, and stepped out into the midnight chill to wash his arms in a bucket of cold well water. The Don had paid him a double eagle—twenty dollars in heavy, yellow gold—and offered him a bed in the bunkhouse. Arthur had refused. A man who slept under another man’s roof ended up tangled in that man’s business, and Don Manuel Armijo struck Arthur as the sort of grandee whose business usually involved men getting shot in the dark.

By the second hour after dawn, Arthur was back in Mesilla, his knuckles throbbing with a dull ache and his pockets ten times heavier than they had been twenty-four hours before.

The town was waking up dry. A pale, powdery dust, fine as flour and tasting faintly of alkali, hung two feet above the dirt lanes, kicked loose by the early traffic of milk goats and carretas. The southern wind had picked up, sweeping across the Jornada del Muerto and rattling the dead husks of last year's corn in the garden patches behind the adobe walls.

Arthur led Copper into the yard behind the San Albino church. The livery there was run by an old German named August Breuninger, a veteran of the Mexican War who had lost an ear at Buena Vista and had spent the subsequent thirty-six years nursing an abiding hatred for mules and politicians.

"You smell like a slaughterhouse, Arthur," Breuninger said by way of morning greeting, squinting from beneath the broad brim of a palm-leaf hat. He was scraping the dried crust of grease off the spindle of a light buckboard.

"A slaughterhouse smells cleaner," Arthur said, loosening the cinch and swinging his saddle down onto an upturned barrel. "I spent the night with Don Manuel's Kentucky stud."

The German stopped his scraping. He wiped a thumb against his canvas apron and looked up, his single ear twitching slightly. "He's still alive, the bay?"

"He's alive. Eating soft bran out of a bucket by now if Miller did what I told him."

"Then you are a wealthy man or a dead man," Breuninger remarked, turning back to the iron spindle with a rasp. "Don Manuel does not tolerate half-measures. Two months ago, a boy from Las Cruces shorted him three sacks of pinto beans on a freight delivery. The boy's father had to deed over his milk cow to pay the difference, and the boy was seen walking toward Sonora with his ribs showing through his shirt."

"I got paid," Arthur said, patting the pocket of his duck trousers. The gold piece tapped against the silver dollars from O'Shea with a dull, satisfying clink. "Put Copper in the box stall with the good oat hay. He's had two miles of sand hills this morning, and he’s earned his breakfast. Don't water him till he cools."

"The buckskin eats better than my grandchildren," Breuninger grunted, but he took the reins with a soft, practiced hand that belied his sour tongue.

Arthur carried his leather roll across the alley to the back room of the boarding house run by Señora Ortiz. It was a low-ceilinged room with walls of white gypsum plaster that dusted off on your coat if you brushed too close. The furniture consisted of a pine rope-bed with a straw tick, a single chair with a rawhide seat, and a tin washbasin on an iron tripod.

He poured half a pitcher of water into the basin, stripped off his salt-rimed shirt, and went to work on his skin with a bar of yellow lye soap. The lye bit viciously into the fresh scrapes across his forearms where the stallion's sharp lower incisors had grazed him, but Arthur worked the lather until his skin was raw and pink. A horse dentist who let an infection take root in his forearms was a man who soon found himself looking for work with only one arm, and one-armed men did not long survive in the territory unless they were very quick with a derringer.

When he was clean, he put on a fresh shirt of gray wool flannel, buttoned his duck vest, and took his rasp roll down to the low bench outside the room to tend to his tools.

The care of the instruments was the closest thing Arthur had to religion. A dull float was worse than useless; it crushed the enamel instead of shearing it, driving microscopic fractures deep into the dental arcade that would gather rot by midsummer. He took a three-cornered file and began dressing the teeth of the diamond-headed rasp, setting each cutting edge with a sharp, rhythmic stroke that sang against the hot morning air. Chink. Chink. Chink.

Down in the plaza, the town was coming to life.

From his bench beneath the cottonwood ramada, Arthur had a clear view across Calle Principal toward the open square. Mesilla’s plaza was a sprawling, dusty rectangle bounded by flat-topped adobes whose timber vigas stuck out through the plaster like the ends of severed bones. In the center, a small wooden bandstand sat peeling in the sun, surrounded by a ring of ragged chinaberry trees that cast pools of gray shade over the baked earth.

A party of horsemen was riding into the square from the north road, the one that led up through Doña Ana from the ferry crossing.

Arthur paused his filing, the iron tool held motionless against the steel rasp.

There were four of them. They rode big, rangy geldings—not the small, tough Mexican ponies the local vaqueros favored, but grain-fed American horses with long legs and heavy bones, the kind bred in Missouri or northern Texas. The men sat their saddles with the slouching, careless arrogance of men who had spent their youth in brush country and their manhood behind a six-gun. They wore broad-brimmed hats pulled down low against the glare, linen dusters grayed with trail grime, and saddle scabbards holding modern lever-action rifles—Winchester seventy-threes, their yellow brass receivers catching the nine o'clock sun.

The leader of the group was a tall man with wide, sloping shoulders and a beard cut square at the collar. He rode a heavy dapple-gray that favored its near front leg, nodding its head with a slight, hitching dip every three strides.

"Look at that," Arthur muttered to himself.

"Look at what?" Breuninger had come around the corner of the livery, carrying a bucket of boiled linseed oil and an old rag. He stopped beside the bench, his squinted eyes following Arthur’s gaze.

"That gray horse," Arthur said. "Look at the way his head drops when the left shoe strikes."

"Navicular," the German said after a moment's squinting. "Or a gravel in the white line."

"Neither," Arthur replied, laying the file across his knees. "Watch his ears. If his foot hurt him, his ears would flop forward with the drop to catch his balance. He's holding them back flat against the crown. He's not lame in the foot. He's got a broken curb in his mouth, or a jaw fracture that’s pulling when the bit takes the slack."

The four riders didn't stop at the livery. They swung their mounts around the bandstand and pulled up in front of the cantina owned by Mariano Barela, a long adobe building that sat opposite the courthouse on the west side of the plaza.

The tall man with the square beard dismounted first. He didn't drop his reins to the dust like a cowhand; he tied the gray securely to the cedar hitch-rail with a tight clove hitch, leaving the horse’s head pulled up high against the wood. The gray immediately tossed its head, throwing white lather from its lips, and began shaking its muzzle against the peeled log with a wet, thumping sound.

The rider turned and hit the horse once across the bridge of the nose with the flat of his heavy leather gauntlet.

The gray backed up to the end of the reins, snorting and rolling its eyes, but it stopped fighting the wood. The four men stepped up onto the portal, their spurs ringing loud against the hard caliche, and pushed through the bat-wing doors into the cool darkness of the cantina.

"You know them?" Arthur asked.

"I know of them," Breuninger spat, dipping his rag into the oil. "That is Wade Clanton. He runs cows up in the San Mateo mountains. Leastwise, that is what he tells the tax assessor in Las Cruces. Others say he buys Mexican steers down in Sonora for three dollars a head in lead and sells them up at Fort Craig for twelve dollars in Treasury vouchers."

"He's hard on horseflesh," Arthur said.

"He is hard on everything that cannot shoot back," said the German. "A year ago, he had a dispute with an old man over a water right near the Organ gap. The old man’s ditch dried up three days later, and when he went up the canyon to see why, someone put a rifle bullet through the crown of his hat. He moved to El Paso the next morning. Left his peaches to rot on the trees."

"Law in town?"

"The sheriff is in Las Cruces," Breuninger said, chuckling without humor. " Las Cruces has the railroad, so Las Cruces has the money, which means Las Cruces has the law. Mesilla has three constables who are very good at arresting drunk sheep-shearers on Saturday night and very busy cleaning their carbines whenever Wade Clanton comes to town."

Arthur looked back down at his file. He had sixty teeth left to dress on the angular rasp, and the sun was climbing toward ten o'clock, turning the plaza into an oven. It was none of his affair. An itinerant horse doctor survived by keeping his nose between the bars of a horse's jaw and out of the business of men who carried Winchesters. In three days, he’d have enough money saved to buy a second pack mule and head north along the river toward Albuquerque, where the big cavalry posts paid top dollar for seasonal maintenance on their remounts.

He went back to work. Chink. Chink. Chink.

Twenty minutes later, the door of the cantina banged open.

It wasn't Clanton who came out, but one of his hands—a younger man, narrow-hipped and wiry, with hair that hung in greasy brown strings from beneath an old Confederate slouch hat. He carried a half-empty bottle of aguardiente in his left hand and looked around the glare of the plaza with the loose, wandering eyes of a man who was already three drinks ahead of the sun.

His eye caught Breuninger’s sign: LIVERY & FARRIER - A. BREUNINGER.

The young hand stumbled down the two wooden steps, his boot heels dragging through the dust, and crossed the open expanse of the plaza toward the livery yard. The heat was shimmered up from the dirt now, making the boy’s legs look like they were wading through a shallow pool of water.

Arthur didn't look up from his work, but his hands slowed.

The rider stopped four feet from the ramada, leaning his weight against one of the cedar posts that held up the willow brush. He smelled of sweat, cheap liquor, and woodsmoke.

"Hey, Dutchman," the boy said, his voice high and drawling. "Which one of you is the smith?"

Breuninger didn't stop rubbing his linseed oil into the wood. "I am the wheelwright. If you need ironwork, the shop is behind the church. But it is closed till noon."

The boy took a pull from his bottle, swallowed with a wet grimace, and wiped his mouth with the back of a dirty sleeve. "Don't need ironwork. Need a horse fixed. Wade's gray is acting the fool. Won't take the bit without throwing his head, and he's chewing his tongue to red meat. Wade wants someone to take a pair of tongs and knock out whatever's biting him."

Breuninger shook his head once. "I don't touch teeth. You want teeth pulled, talk to Arthur here. He’s the tooth-carpenter."

The boy turned his pale, bloodshot eyes toward Arthur. He looked at the long, canvas roll laid out on the bench, the rows of oiled steel rasps, the heavy brass speculum with its geared ratchets, and the long-handled extraction forceps that looked like small cannon levers.

"You a vet?" the boy asked, sneering slightly.

"I float teeth," Arthur said, his voice flat. He didn't stop the regular, even motion of his file.

"Wade says get over there and see what’s wrong with that gray. He’s got five miles to ride after dinner and he don't like a horse that shakes the reins."

"The gray is tied too high," Arthur said without looking up. "Tell your boss to drop the lead three feet so the horse can get his head down, and take that curb bit out of his mouth. He’s got a high palate and that port is driving right into the roof of his mouth every time Clanton yanks the rein."

The boy blinked, his drunk brain struggling to process the advice. Then his eyes narrowed, the easy contempt of a frontier bully rising to the surface.

"I didn't ask for a sermon on bits, mister. I said Wade wants you to bring your tools over to the rail."

"The tools stay here," Arthur said mildly. "If Clanton wants the horse looked at, he can lead him across the plaza into the shade of the barn. I don't work in the sun, and I don't work at a public hitch-rail."

"You don't know who Wade Clanton is, do you?"

"I know he's got a gray horse with a sore mouth," Arthur said. "And I know the horse has more sense than the man who tied him up."

The boy stood up straight, letting the bottle dangle loose between two fingers. A dark, ugly flush crept up from his collar, coloring his unshaven jaw. In the territory, words like that usually ended with the sharp clack-clack of a hammer being drawn back, and for a second, Arthur felt the skin across his ribs tighten in anticipation. He didn't move his right hand toward his pocket, but he tilted the three-cornered file so that its heavy, pointed tang was resting against the meat of his palm. A six-inch file with a tempered steel point could punch through a wool vest and two inches of muscle if a man leaned his shoulder behind it.

The boy opened his mouth to say something, but a voice cut across the hot air from the direction of the plaza.

"Jesse."

It was Wade Clanton. He had come out of the cantina and was standing on the edge of the portal, his thumbs hooked into the broad leather belt that carried his holster. Even fifty yards away, his square beard and wide frame seemed to fill the street.

"What's the holdup?" Clanton called out, his voice carrying clearly over the rattle of the cottonwood leaves.

The boy, Jesse, looked back over his shoulder, then spat into the dust at Arthur’s feet. "The tooth-mechanic says he don't walk across the road for nobody. Says you got to bring the horse to him."

Clanton stood still for three seconds. He didn't look angry; he looked interested, the way a butcher looks at a calf that doesn't want to enter the chute. He stepped down off the portal, his boots thumping on the caliche, and walked to the hitch-rail. He untied the gray with a single jerk of his wrist and led the horse across the dirt square.

The gray walked behind him with that same hitching, painful nod, its white nose mottled with pink foam where the iron bit had scraped the delicate skin of the bars.

Clanton didn't stop until he was under the edge of Breuninger’s ramada. The gray blew a wet, rattling snort that smelled faintly of sour mash and old blood, its dark eyes white-rimmed with fear and pain.

Clanton looked down at Arthur, who had finally set the file down on the bench.

"You the man who works on teeth?" Clanton asked. His voice was lower than his hand’s, carrying the deep, raspy resonance of a man who had smoked too much black leaf and shouted over too many river crossings.

"I am," Arthur said, rising slowly to his feet. He was not as tall as Clanton, but he had the thick, square shoulders of a man who worked with iron and animal bone twelve hours a day. He met the cattleman’s eyes without blinking.

"Jesse says you got an opinion on my bit."

"I have an opinion on the horse's mouth," Arthur said, gesturing toward the gray. "Look at the way his lower jaw is set. The lower jaw is narrower than the upper by three-quarters of an inch. That's common enough, but when you put an iron spade bit in a mouth like that and cinch the curb strap tight against the chin groove, you're pinching the tongue between the bar and the iron. The horse isn't being mean, Mr. Clanton. He's trying to keep his tongue from being cut in two."

Clanton’s eyes flickered down to the gray’s mouth, then back to Arthur. He seemed to be weighing the words not for their truth, but for their insolence.

"He was five hundred dollars out of Missouri," Clanton said. "He was broke to a snaffle, but a snaffle don't turn a steer when you're running through the mesquite. He needs iron to know who's riding him."

"Iron won't teach him anything except how to rear," Arthur said. "Let me look inside."

He stepped up to the gray’s head. The horse flinched, pulling back against Clanton’s grip on the leather, but Arthur didn't reach for the bridle. He reached his left hand out, palm flat, and blew gently into the horse’s nostrils. The scent of a man who worked with animals—the faint, lingering smell of bran, leather, and horse sweat—seemed to register through the animal’s fear. The gray’s ears twitched forward for half a second.

Arthur slid his fingers into the corner of the mouth, avoiding the teeth, and pressed the roof of the palate. The horse opened his jaw with a shuddering groan.

Arthur’s eyes went dark.

"Who took a hammer to this mouth?" he asked, his voice deadly quiet.

Clanton frowned. "Nobody took a hammer to him. We had a smith up in Hillsboro knock off two wolf teeth three weeks back."

"He didn't knock off wolf teeth," Arthur said, stepping back and wiping his fingers on his trousers. "He knocked off the first premolars on both sides of the lower jaw, and he broke the bone clear through the interdental space. There are two loose fragments of the jawbone floating around inside the gum, festering like rotten wood. Every time you pull that curb, you're grinding those loose chunks of bone into the mandibular nerve."

Jesse, who had followed his boss across the square, gave a short, braying laugh. "Told you, Wade. The horse is just sour."

Clanton didn't laugh. He looked at Arthur with cold, calculating eyes. "Can you take the loose bone out?"

"I can," Arthur said. "It will take an hour. I'll have to lance the gum, draw the shards with forceps, and wash the pocket with salt and carbolic. And he won't carry a bit for three weeks. You'll have to ride him in a hackamore or leave him in a pasture."

"I don't ride hackamores," Clanton said flatly. "And I don't leave five-hundred-dollar horses in pastures for three weeks. We're crossing the river for Doña Ana this afternoon. I've got three hundred steers waiting at the pens to be tallied, and I need this gray under me."

"Then you'll ride him till he goes mad," Arthur said, picking up his file again. "By next Tuesday, the infection will reach the joint at the base of his ear. He'll drop dead in the road, or he'll flip over backward and break your neck trying to get away from the pain. Suit yourself."

The silence beneath the ramada became very thick.

A dry gust of wind came through the alley, carrying a sheet of yellow dust that hissed against the adobe wall. Breuninger didn't move; his oil rag was held frozen against the wagon wheel, his single ear cocked like a hare’s.

Clanton’s right hand moved slowly, almost casually, dropping down toward the walnut grips of the Colt at his hip. "I don't like being told how to handle my stock, Phelan. Especially not by a tramp who carries his living in a carpetbag."

Arthur didn't reach for his file this time. He just stood there, his scarred knuckles resting loose against his seams. He had seen three men shot in his life, and none of them had had time to say anything clever before the lead took them. He knew that if Clanton drew, there was nothing between his flannel shirt and forty grains of black powder except six feet of dusty air.

"A tramp who knows his trade," Arthur said, keeping his voice as level as a spirit level. "Don Manuel Armijo paid me twenty dollars last night for saving his thoroughbred stud. If you want to shoot me over a five-hundred-dollar gelding with a broken jaw, you go right ahead, Mr. Clanton. But the Don might wonder why his horse dentist didn't come back to check the stitches tomorrow morning."

The mention of Armijo’s name fell into the heat like a chunk of ice into a hot frying pan.

Clanton’s hand stayed where it was, but his fingers didn't tighten on the leather. His eyes narrowed until they were small, black slits in his bearded face. The Armijos did not just own land; they owned the judges, the freight roads, and the men who supplied the beef contracts to the forts. A cattleman who fell out with the Don in the spring was a cattleman whose herds were quarantined for Texas fever by midsummer.

"You worked on the Don's bay?" Clanton asked.

"Ask Miller," Arthur said. "He’s probably at the depot right now seeing to the oats."

Clanton stood for a long moment, the wind tugging at the greasy brim of his hat. Then he slowly brought his hand back up and tucked his thumb into his belt.

"Jesse," Clanton said without turning his head.

"Yeah, Wade?"

"Take the gray back to the livery. Put him in a stall. Tell Breuninger to give him bran."

Jesse’s jaw dropped. "We ain't riding him across?"

"We're taking the mules," Clanton snapped, his voice turning vicious. "Move, before I take a quirt to your shoulders."

The boy scrambled to take the gray’s reins, his face dark with confusion and sullen rage. He led the limping horse around the corner toward the back pens, his spurs dragging in the dirt.

Clanton turned back to Arthur. He stepped closer, until Arthur could smell the sour whiskey and the grease on his duster.

"You fix that horse," Clanton said, his voice dropping into a harsh, dry whisper. "You take the bone out, and you wash it with your carbolic. I'll pay you three dollars when I get back from Doña Ana on Friday. But if that horse isn't fit to carry a saddle by the end of the month, I’m going to take that long rasp of yours and ram it down your throat until the handle hits your teeth. You understand me, horse-leech?"

Arthur didn't give him an inch. "Three dollars is for a simple float, Mr. Clanton. Bone extraction is five. And you pay half now, or the tools stay in the bag."

Breuninger let out a small, strangled gasp behind the wagon.

Clanton stared at Arthur. For three seconds, Arthur thought the man was going to hit him with his bare fist. The muscle in Clanton’s right temple twitched with a rapid, irregular jump.

Then, slowly, the cattleman reached into his pocket and pulled out a silver half-dollar and two silver dollars. He didn't drop them into Arthur’s hand; he flipped them with his thumb, one by one, into the dust between Arthur’s boots.

"Two fifty," Clanton said. "The rest when I see the bone."

He turned on his heel, his duster swirling around his calves, and walked back across the plaza toward the cantina, his boots kicking up small puffs of white dust that hung in the bright, merciless light.

Arthur watched him until the bat-wing doors swung shut behind him.

Only then did he let his breath out. It came out slow and ragged, his chest aching where he had held it tight against the threat of the iron.

"You are a fool, Arthur," Breuninger said softly from the shade. "A complete, certified, German-grade fool. Wade Clanton does not forget a man who makes him back down in the plaza."

"He didn't back down from me," Arthur said, bending down to pick the silver pieces out of the dirt. He wiped the dust off them against his thigh and dropped them into his vest pocket. "He backed down from Don Manuel Armijo. There's a difference."

"Not to Clanton," Breuninger muttered, going back to his wheel. "To Clanton, it’s all the same debt. And he collects his interest in lead."

Arthur picked up his canvas roll and buckled the twin straps. The sun had crossed the line of the ramada now, striking the bench with a heat that felt like an open oven door. His mouth tasted like alkali and stale coffee, and the work on the gray was going to be hot, bloody, and dangerous.

"Get me a bucket of boiling water, August," Arthur said, turning toward the livery barn. "And bring your heaviest pair of nippers. We've got bone to dig."

He walked into the dark, manure-smelling cool of the barn, leaving the dust and the plaza behind him, but he could feel the weight of the silver in his pocket like three small pieces of lead, cold and heavy against his ribs.
