He walked back toward town alone, and Caleb stood in the white glare of the creek bed a long time after he was gone.

The past came for Caleb that afternoon in the livery, the way it always did when he was tired — not as a memory but as weather, settling over him sudden and total.
Cedar Flats. Six years ago.
He'd been younger then, surer, drunk on his own gift. The rods had pulled so hard in his hands he'd nearly dropped them, right there on the Hardesty place, and he'd told them to dig — told them with a dowser's certainty, the kind men paid money for. They'd dug ninety feet through caliche that broke three drill bits. Ninety feet, and the hole came up dust.
The Hardestys couldn't afford a second hole. The well they'd had went alkaline that same summer. So they loaded the wagon in September — Jacob Hardesty, his wife Anna, the two little girls, Ruth and May — and struck out for the Rio Grande settlements with eight gallons of water and Caleb's assurances ringing in their ears.
They found the wagon eleven days later, twenty miles short of water. The children first, curled together under a blanket like they were sleeping. Anna with her head in her husband's lap. Jacob last, sitting upright against the wheel with the reins still in his hands, as if he'd died trying to drive them somewhere better.
Caleb had stood at those graves with the rods in his hands and wanted to snap them over his knee. He'd been wrong. Men paid for certainty and he sold it, and four people paid the difference.
That was the arithmetic he carried. That was why, when Sheriff Crowe told him to ride out of Copper Creek, something in his chest closed like a fist.
He couldn't save the Hardestys. He'd tried to tell himself for six years that it wasn't his fault — the land lied, the rods lied, drought was God's business. But the truth sat in him like a stone: he'd been certain, and he'd been wrong, and people died.
He would not ride out of another town and read about its dead in a newspaper six months later. Not again. Not this time.

He found Elise in the schoolhouse at dusk, sweeping ash off the floorboards though the fire had never reached the building itself. She moved like a woman twice her age. The cistern was gone. The well-house was a black scar. Everything she'd built in secret for a year had been unmade in a single night.
"I'm sorry," he said from the doorway.
She leaned on the broom. "For what? You didn't light it."
"For bringing it down on you. Whitmore didn't know about the cistern until we started asking questions. That tally page — they missed it, and now—"
"Stop." She set the broom against the wall and came to stand in front of him, and her eyes were dry and furious and absolutely clear. "Don't you dare apologize for finding the truth, Caleb Mercer. My father died for it. Those families drank because of it. If Whitmore wants to burn things, let him burn. It only proves he's afraid."
"He'll do worse than burn sheds, Elise."
"I know." She said it simply, the way you'd say the sky was blue. "Then we finish it."
The words landed in him like a hammer on an anvil. He thought of the Hardestys under their blanket. He thought of Crowe's tired arithmetic. He thought of Whitmore's water selling for a dollar a barrel while children drank mud.
"All right," he said. "We finish it."

He was oiling his saddle in the livery after full dark when the door scraped open and Amos Barlow filled the doorway — sixty years old, arms like oak limbs, Elias Hartwell's oldest friend, carrying a wooden crate the way you'd carry a sleeping child.
He set it down between them without ceremony and pried the lid with his thumbnail.
Dynamite. Twelve sticks, waxed paper sweating in the heat, packed in sawdust. Blasting caps in a separate tin. Fuse coiled like a snake.
Caleb stared at it. "Hiram."
"From the mine," Hiram said. "I was a powder man twenty years before I was a blacksmith. I know what I'm doing." His big hands rested on the crate, steady as stone. "Elias and I dug that well together when Elise was in pigtails. I stood at his funeral and listened to the preacher call it an accident, and I said nothing, because I had a shop and a life and I did the arithmetic." He looked up, and his eyes were wet and furious. "I'm done with the arithmetic, Caleb."
Hiram nodded at the crate. "You'll need this. And you'll need me."
They met in the livery's back room after midnight — Caleb, Elise, and Hiram — with the dynamite crate between them like a fourth conspirator and a single lantern turned low.
Hiram did the talking. He laid it out the way a man lays out tools: in order, each one placed deliberate.
"Three families filed on the creek last year," he said. "The Dunns. The Parkers. Old Sam Toller." He ticked them off on fingers thick as hammer handles. "Every complaint went to the territorial water commissioner's office in Prescott. Every one of them died there. No investigation, no reply, nothing. Like dropping stones down a well and never hearing them land."
"Maybe they were just—" Elise started.
"Buried?" Hiram's smile had no humor in it. "Elias didn't think so. Two months before he died, he came to my shop after dark and showed me a letter he'd gotten from a friend in the assay office up in the Bradshaws." Hiram reached inside his coat and drew out a folded paper, worn soft at the creases. "I kept it. Read it."
Elise took it with both hands and read aloud, her voice steady in the lamplight:
