The Moth in the Sill

The town of Harlow’s Mill sat in a valley where the fog never quite lifted until noon. It wasn’t a place you visited; it was a place you passed through, unless you had a reason to stop. I had a reason, or rather, a job. I was a structural inspector for the county, and the old gristmill at the edge of town had been scheduled for demolition. But before the wrecking ball swung, someone had to go in and certify that the building was empty.

I didn’t expect company. The mill had been abandoned for decades, its windows boarded, its wheel frozen solid. But when I pulled up in my truck, there was a dusty sedan already parked out front, and a couple—maybe mid-fifties—standing by the door, looking at the building with a reverence that made me uneasy.

They introduced themselves as the Morrows. Roland and Edith. Roland had the weathered hands of a carpenter, and Edith wore a scarf even though it was warm. They told me they were renovating the old inn at the center of town, the one that used to be a stagecoach stop. They’d heard about the mill, and they wanted to salvage some of its beams for the inn’s great room.

I didn’t mind the company, but they lingered. They asked me what I knew about the mill’s history. I told them it was built in the 1830s, run by a family named Whitlock, and that it had ground flour for the whole county until the 1950s. They nodded, and then Roland said something that made my skin prickle.

‘We’ve had guests at the inn tell us strange things about this mill,’ he said. ‘We thought they were just stories, until we started noticing things ourselves.’

I asked what kind of things. Edith looked at the mill, then at me, and said, ‘Moths. Big ones. They keep appearing in the windowsills of the inn, even in winter. And every time one shows up, someone checks out early, pale as bone.’

I laughed, but it sounded hollow. ‘Moths are harmless.’

Roland shook his head. ‘Not these. They have markings on their wings that look like faces. And when you get close, you can hear them scratching on the glass, like they’re trying to get in.’

I should have brushed them off and gone about my business. But something in the way Edith said it made me look at the mill’s old windows. The boards had warped, leaving cracks, and I could see darkness beyond. And in that darkness, I thought I saw a flutter of wings.

We decided to go in together. I had a flashlight, and Roland had a crowbar to pry open the door. The air inside was cold and thick with dust. The floorboards groaned under our weight. The mill machinery was still there—great gears and wheels, frozen mid-rotation, draped in cobwebs. And everywhere, on every surface, were moth carcasses. Thousands of them, their wings crumbling to powder at the slightest touch.

I told myself it was just an infestation. But Edith pointed to the sill of a shattered window, where a single moth perched, alive. It was larger than my hand, and its wings were patterned like a screaming face. It didn’t fly away when I approached. It just sat there, vibrating, and I could hear it—a faint, high-pitched scratching.

Roland whispered, ‘That’s the one. That’s the same pattern.’

I felt a chill that had nothing to do with the cold. I asked them what they meant by ‘the same pattern.’

Edith took a breath. ‘Every time we see one of these, we find a diary or a letter somewhere in the inn, left by someone who stayed there, written by a person who died within a week. They all describe the same thing: a moth with a face of a lost soul, scratching at the window, begging to be let in. And then, the person feels compelled to open the window. And when they do, the moth flies in and lands on their mouth. And then they feel it burrowing, and they can’t scream, and the next morning, they’re found with their tongue missing.’

I stepped back, nearly tripping over a pile of rotting grain. ‘That’s just a story. A myth.’

Roland pointed at the moth. ‘Look at its mouth.’

I didn’t want to, but I did. The moth’s proboscis was not the usual thin tube. It was thick, fleshy, and it looked like it was covered in tiny teeth. And it was aimed at us, as if it could sense our breath.

The moth flew. It didn’t flutter; it darted, straight at Edith’s face. She screamed and swatted it away, but not before it brushed her cheek. She stumbled back, and I saw a thin line of blood on her skin. The moth landed on the far wall, and I swear it was watching us.

We ran. We didn’t stop until we were outside in the sunlight. Edith was trembling, dabbing at the cut with her scarf. Roland was pacing, muttering about going back to the inn and burning it down. I told them to go home, to stay away from the mill, and that I’d report it as condemned.

They left. I watched their car disappear down the gravel road. I turned back to the mill, and for a second, I saw a figure pressed against the dark window—a man with a gaping hole where his mouth should be. Then it was gone.

I got in my truck and drove back to the county office. I filled out the demolition order with a shaky hand. I didn’t mention the moths. I didn’t mention the couple. I just wrote ‘unsafe structure,’ and that was that.

A week later, I heard that the demo crew had gone missing. The sheriff called me, asking if I’d seen anything strange. I said no. But that night, I found a moth on my windowsill—a big one, with wings that looked like a face I almost recognized. It scratched on the glass, soft and rhythmic, like a fingernail tapping.

I haven’t opened the window. I’ve boarded it shut from the inside. But the scratching doesn’t stop. It moves from window to window, following me through the house. And I know, sooner or later, I’ll make a mistake. I’ll leave a screen unlatched, or I’ll fall asleep with a cracked pane. And I’ll hear the flutter, and I’ll feel the weight on my lips, and I’ll remember the man in the mill, the one with the missing mouth, and I’ll understand why he was pushing against the glass, trying to warn us.

The moths are just the messengers. The real horror is what they carry—the last breath of someone who spoke their final words too close to a window, and the lonely soul that got left behind, still looking for a way in.
