The cedar tree by our back porch always drops those sticky little seed pods right around the time the mountain air turns sharp enough to bite your nose. I used to sweep them twice a day with an old corn broom that had worn down crooked on the left side from forty years of hitting the stone step the exact same way. Harlan never liked that broom. He kept telling me he’d buy me a fresh one down at the hardware store in town whenever he had an extra five minutes, but those minutes never seemed to show up on his pocket watch.

By late October, though, the corn broom didn’t matter much anymore because the house had taken on a new smell that no amount of pine cleaner or open windows could ever quite chase out. It wasn’t the regular sort of smell you get used to living out here in the foothills, where grease and woodsmoke and damp work boots just sort of settle into the rugs like old friends. This was sharp. It smelled like rusted pennies and wet gravel left to bake in an iron skillet, something metallic and sour that clung to the backs of my teeth the second I walked through the front door from hanging the laundry.

Harlan started washing his hair in the utility sink down in the basement using the yellow lye soap we usually reserved for greasy tractor chains. I could hear the pipes shuddering through the floorboards while I was up at the stove trying to simmer a pot of pinto beans for supper, the water hammering against the galvanized metal like small shot.

He would come back upstairs twenty minutes later with his hair slicked straight back, his skin scrubbed so hard around his jawline it looked like raw beef, and still that copper smell would roll off him in heavy, invisible waves.

“You smell like the bottom of an old well, Harlan,” I told him one Tuesday when he set his dinner plate down without looking up from the oilcloth.

He just pushed his potatoes around with the tines of his fork until they looked like gray paste. “It’s just the lime at the quarry,” he said, his voice lower than usual, rattling down in his chest the way it did when he had a chest cold he was trying to stubborn his way through. “They’re treating the lower pit with something new to keep the seep-water down. It gets in the pores. You can’t scrub it off with regular soap.”

I didn’t believe him. I had lived with Harlan since I was nineteen years old, through thirty-four summers of limestone dust and nine winters of coal soot when the furnace acted up, and neither one of those ever smelled like a hot battery.

But I let it drop because he looked hollowed out, his cheekbones pressing hard against his skin like two dry knuckles under a blanket.

The real break came on a Friday morning when he couldn’t lift the five-gallon fuel can out of the back of his pickup without letting out a little whistling gasp through his teeth. I was standing by the porch rail with my apron still tied behind my back, watching him drop his chin against his chest as if his neck had suddenly forgotten how to hold his skull upright.

“We’re going down to see Dr. Evans,” I told him, not asking, just setting my mug down on the wood. “Put your good shirt on. The blue one with the snaps.”

He didn’t argue, which scared me worse than if he had slammed the truck door and driven off to the gravel pit. A man who won’t fight you over wasting a morning at the clinic is a man who knows something the doctor is going to have to write down on a white card.

The waiting room at the clinic smelled faintly of old magazines and floor wax, that cool, dead kind of clean that makes you want to breathe through your mouth. Dr. Evans was an old man who had delivered my sister’s youngest back when the county hospital still had the red brick nursery wing, and his hands always shook just a little bit when he reached for a patient chart. He called Harlan back after twenty minutes of silence where we both sat staring at a poster of a healthy heart that looked suspiciously like a red beet.

I stayed out in the hall for the first five minutes, listening to the muffled murmur of their voices through the hollow core door. Then the latch clicked. Dr. Evans poked his head out into the hallway, his face gone the color of a bruised plum right up to the edges of his wire-rimmed spectacles, and he reached up to wipe his palms on the front of his white coat as if he had just touched something greasy.

“Mrs. McAllister,” he said, his voice dropping an octave lower than it had any right to go. “You might want to come on back into exam room four. Right now.”

My knees felt hollow, like dry corn stalks in November. I didn’t think about his heart or his lungs or anything a doctor usually looks for behind a flannel shirt. I thought about the way the life insurance policy was still sitting in the metal lockbox under the bed and whether I had remembered to sign the renewal slip back in August.

“Is it his liver?” I asked, my hand catching the brass door handle.

“Just come in, Clara,” Dr. Evans muttered, turning his back on me to wash his hands at the corner sink with soap that smelled like green apples.

When I stepped into the little white room, the copper smell hit me so hard my eyes watered, thick and greasy and foul, rising straight off the examination table where Harlan sat with his boots dangling six inches off the linoleum. He wasn’t wearing his shirt. His shoulders were covered in fine, black soot that looked like coal dust, but when I looked closer, I saw it wasn’t coal at all. It was powdered rubber and fine, gray filings that had worked their way into every single pore of his skin until he looked like he had been dusted with graphite.

Harlan wouldn’t look at my face. He was staring down at his own thumbs, which were blackened around the cuticles with grease that didn’t come from a limestone quarry ten miles out of town.

“The quarry closed down in ninety-six, Harlan,” I said, and the words sounded small in that room, like pebbles dropped into an empty bucket.

The doctor dried his hands on a paper towel, wadded it up into a tight gray ball, and dropped it into the pedal bin with a sharp *clack*. “I’ll leave you two for a minute,” he said, slipping out into the hall and pulling the door shut behind him with a quiet, oily click.

Nobody said anything for a second, and honestly that felt worse than the smell. The electric wall clock above the sink hummed a little low B-flat every time the red second hand jerked past the twelve.

Harlan finally let out a long, thin breath that smelled like burnt copper and cold tea. He reached down to pick his blue snap-shirt off the chair seat, turning it over in his hands as if he were trying to find a hole in the sleeve.

“Honey,” he whispered, and his voice cracked right on the middle syllable, high and thin like a dry twig under a boot heel. “There’s something I should have told you a long time ago.”

He didn’t look like my husband anymore. He looked like some old stranger who had hitched a ride on our back porch and forgotten his name by the time he reached the kitchen.

“You aren’t working the pit,” I said. My voice didn’t shake. I was surprised by that. It sounded flat and dry, like an old well with the bucket gone.

“The pit has been dry since the county paved the bypass,” he said, still staring at his thumbs. “I haven’t set foot in the limestone since the winter my brother Gary lost his leg on the threshing machine.”

The name Gary hung there in the small white room between the bottle of rubbing alcohol and the box of tongue depressors. Gary, who lived down in the bottomlands in a double-wide that always looked like it was three days away from sliding into the creek. Gary, who had borrowed four thousand dollars from us back when the corn crop failed in ninety-eight and never mentioned paying back a single nickel of it because he had a heart like a sieve and three kids who needed shoes every September.

“Gary’s debt,” I said.

Harlan nodded once, a short, sharp jerk of his chin. “The loan shark out of Knoxville. The one they call the preacher because he wears those black suits even in July. He bought Gary’s paper from the bank three years ago when the tractor repo didn’t clear the balance. If I didn’t make the monthly draw, they were going to put Gary and the girls out on the shoulder of Route 9 before the first freeze.”

“And the smell?” I asked, though I could already see it in my mind, dark and narrow and deep under the old rail yard where the city used to bury the battery lead back before the EPA put a padlock on the gate.

“The salvage yard by the river,” Harlan said, and now his eyes finally came up to meet mine, red-rimmed and leaking water at the corners. “They pay cash for anyone willing to go down into the old drainage culverts with a cutting torch and strip the copper out of the old transformer casings before the scrap buyers come down from Chattanooga. It’s twelve hours a night. In the dark. The acid from the oil gets into your skin. You can’t wash it off because the pores stay open from the heat.”

I walked over to the exam table and reached out to touch his shoulder, feeling the hard, dry ridge of his collarbone right through the layer of industrial soot. His skin felt like old parchment that had been left out in the sun too long, hot and brittle.

“You’ve been doing that every night since the frost?” I asked.

“Since the first of August,” he said. “Three thousand a month cash under the table. I cleared the note last Tuesday. The paper is sitting in the top drawer of my work desk in the shed.”

I stood there for a long time, listening to that clock hum its little B-flat against the wall. Forty-one years we had lived in that house on the ridge, never taking a penny from anyone, never missing a church tithe, never letting the butcher write our name in the back of his ledger. And all the while my husband had been crawling around in the dark under the river like some kind of mole just to keep Gary from losing the roof over his girls’ heads.

“You should have told me, Harlan,” I said, and my hand stayed right there on his shoulder, feeling the way the muscle twitched under the grime. “We could have sold the south pasture. We could have told Gary no.”

“Gary didn’t have nobody else,” he whispered. “And I couldn’t look at you and tell you I let my own blood get turned out into the dirt.”

The ride home was quieter than the clinic. We didn’t turn on the radio because the dial had been stuck on the grain market report since the spring, and neither one of us cared what soybeans were bringing in Kansas. The sun was dropping down behind the ridge, throwing long, purple shadows across the corn stubble that looked like bruised fingers pointing toward our fence line.

When we pulled into the gravel drive, the house looked small and gray against the dark timber of the mountain. Harlan killed the engine, but he didn’t reach for the door handle right away. He just sat there with his hands resting on the steering wheel, looking out through the windshield at the corn broom leaning crooked against the porch step.

“I’m quitting the yard,” he said, and his voice sounded a little more like the man I married forty summers ago. “The debt’s gone. The paper’s burned. I told the fellow down there I wasn’t coming back for the night shift.”

“Good,” I said, opening my door and letting the cool mountain air rush in to clear out the copper smell that had lived in the truck cab for an hour. “You’re too old to be crawling around in drainage pipes, Harlan. We’ve got enough trouble without you turning into a scrap heap.”

We walked up the gravel path together, side by side, neither one of us moving very fast. Inside the kitchen, the pot of beans had gone cold on the back burner, a thin skin forming over the top like gray ice on a puddle.

Harlan didn’t go to the basement this time. He walked straight past the kitchen table, out through the back screen door to where the old iron pump stood over the cistern by the garden fence. I watched him through the screen as he worked the long wooden handle up and down until the water came up coughing and brown before turning clear and cold against the iron trough.

He stripped his plaid shirt off right there in the yard, dropping it into the dirt by his boots, and then he took the heavy yellow bar of lye soap out of his pocket. He didn’t say a word. He just stood under the fading light of the mountain evening, scrubbing his forearms until the red skin showed through the soot, rinsing himself over and over again with water drawn straight from the dark heart of the hill.

I went into the pantry, pulled a clean linen towel off the bottom shelf, the good ones with the blue cross-stitch my mother gave us when we moved in, and carried it out to the back step. I laid it across the wood right where the corn broom had worn the stone smooth, and then I went back inside to light the stove.
