"She was your father's favorite," Hiram said. "He rode her up-creek every Sunday for years. Said she knew every stone between here and the headwaters. After — after Elias, I kept her. Couldn't sell her. Seemed like selling the last witness."
Caleb studied the mare. Old horses carried their histories in their bodies: the white hairs at the muzzle, the patient set of the ears, the way she shifted her weight off a tender foreleg. "We'll bring her back by dark," he said.
"You bring yourselves back by dark," Hiram said. "That's the part I'm particular about." He hesitated, then reached into his apron and pressed something into Caleb's hand — a short iron pry bar, blacksmith-made, heavy as a promise. "Elias was my friend forty years. If that mare takes you somewhere worth seeing, you may need to open something that doesn't want opening."
They led Clover on foot down to the creek bed, and the old mare went willing as water downhill, her ears pricked forward the moment her hooves touched the dry sand of the channel. The creek bed ran pale and cracked between its banks, a white scar through the brown land. Here and there a stagnant pool lay green and buzzing with flies. A dead cottonwood had fallen across the channel a winter back and nobody had moved it, because there was no water worth clearing for.
Elise walked beside Caleb, the lead rope loose in her hand. "Where my father used to ride," she murmured. "Every Sunday. Rain or shine, drought or flood. He'd come home with his boots wet and say the creek was talking."
They followed the dead channel west, toward the bend where Caleb had found the tool marks three days before. The sun climbed and the heat came down like a hand on the back of the neck. Clover plodded steady, unbothered, until they reached the bend — and there the old mare stopped, lifted her head, and swung it toward the north bank with sudden, unmistakable purpose.
Caleb felt the hair rise on his forearms. "She remembers."
The north bank rose in a tumble of sandstone ledges toward a notch in the foothills — a trail, or the ghost of one, switchbacking up through scrub juniper. Clover didn't wait for discussion. She stepped out of the creek bed and started up the bank, the lead rope drawing taut, her old legs finding the path with a certainty that made argument ridiculous.
"Follow Clover," Elise whispered. "Just like he wrote."
They went up. The trail climbed through country that got wilder with every rod — the juniper giving way to piñon, the piñon to bare red rock. Twice Caleb stopped to read the ground the way he'd been trained to read it: a broken twig at horse height, a scuffed stone, the faint parallel lines of something dragged. Somebody used this trail. Somebody used it often.
An hour up, the trail leveled onto a bench of land, and Clover stopped at the mouth of a box canyon — a great red-walled throat opening in the foothills, its walls rising two hundred feet sheer on either side. The old mare stood blowing softly, her good eye fixed on the darkness inside, and would go no further. She'd brought them to the door. The rest was theirs.
Caleb tied her in the shade of an overhang with water from his canteen in his hat for her to drink, and he and Elise went forward on foot to the canyon mouth.
The sign was there before they'd taken twenty steps, plain as print in a primer.
Wagon ruts. Fresh ones — the sharp edges of the iron tires still crisp in the dust, not yet softened by wind. Two wagons, by the gauge, running in and out. And boot prints overlaid thick: work boots, all headed one direction in the morning's cool and back the other way by afternoon, judging by the depth. Somebody had dropped a barrel hoop, bent and rusted. Somebody else had left cigarette papers scattered where men waited. Off to one side, a cook-fire's blackened stones, used within the week.
Caleb crouched over the ruts and laid his palm in one. The dust was still packed hard from weight. He looked up at Elise, and her face was white under the dust and the sun.
"Supplies," she said quietly. "Somebody hauls supplies up there regularly. Men don't eat and smoke and mend harness in a canyon nobody goes to."
"No," Caleb said. He straightened up, and the pry bar hung heavy in his coat pocket, and Elias Hartwell's letter lay folded against his heart like a second pulse. "They don't."
Above them, the canyon walls caught the afternoon sun and burned red as banked coals. Somewhere deep inside, water moved — Caleb could feel it the way a dowser feels it, a cold thread in the rock, a held breath. A whole creek, stolen and penned, running secret through stone.
Clover stamped once in the shade behind them, impatient, as if to say: *I brought you. Now go and see.*
They went back up at dusk.
Caleb had argued for it and Elise hadn't argued against — daylight would have put them on that trail in full view of any man Whitmore posted to watch it, and the fresh ruts at the canyon mouth said the trail was watched the way a bank watches its vault. So they waited out the brutal afternoon in the shade of the overhang with Clover, dozing in shifts, and when the sun dropped behind the western mesas and the canyon mouth went purple with shadow, they went in on foot, leading the old mare.
Clover needed no leading. The moment they entered the canyon's throat she took the point, her hooves finding the path in the gathering dark with the sureness of twenty years of Sundays. Elias Hartwell had ridden her up here every week, Caleb thought, right up until the week he died. The mare was walking her master's last road, and she knew every stone of it.
The canyon ran straight as a rifle barrel for half a mile, walls closing overhead until the sky was a violet ribbon. Then it bent — and Caleb stopped so sudden Elise nearly walked into him.
There are sights that rearrange a man's understanding of the world the way an earthquake rearranges a town. This was one.
