I moved to Aberfan, not for the scenery or the quiet, but because the rent was almost nothing. The village clung to the hillside like a barnacle, its rows of terraced houses stacked against the gray Welsh slate. My flat was in the oldest row, Number 13, a number that made the landlord chuckle and lower the price further. I told myself I didn’t believe in omens. I was wrong.
That first week, I noticed the silence. It wasn’t a peaceful quiet; it was a held breath. The neighbors—what few I’d seen—kept their eyes down, crossing the street if I approached. The only sound was the distant, rhythmic clank of the old colliery machinery, long since decommissioned, yet still groaning in the wind. I chalked it up to small-town suspicion.
But the nights were the worst. The flat had one large window in the living room, overlooking the abandoned coal tip—a black, slick hill that seemed to swallow the moonlight. Every night at exactly 11:23 PM, I’d hear it: a sharp, piercing whistle, so loud it vibrated through my chest. Not a human whistle, but something mechanical, urgent. The first time, I dropped my tea, my heart hammering. I checked the window, the hallway, the boiler. Nothing. I told myself it was a pipe, a train in the distance. But it was too close, too precise. And it always came from the direction of the bathroom, where the window was perpetually jammed open.
On the third night, I had a visitor. An old woman from next door, Mrs. Probert, knocked on my door with a trembling hand. Her face was a map of wrinkles and worry. ‘You hear it, don’t you?’ she whispered, not waiting for an answer. ‘The bell. The thirteen-pound bell. They rang it for the shift change. But the colliery’s been dead for forty years.’ Her eyes darted to my bathroom window. ‘They say when the slag heap shifts, it rings on its own. It’s a warning, see. It never lied before.’ She pressed a small, rusted key into my palm. ‘Lock that window. And whatever you do, don’t open it at 11:23.’ Then she shuffled away, leaving me cold.
I didn’t lock the window. I was a skeptic, a rationalist. Whistles had explanations. I even set my phone to record the bathroom at night. The next day, I played back the audio. At 11:23:03, a piercing, pure tone cut through my own breathing. It lasted exactly seven seconds. The waveform showed a perfect sine wave—no harmonics, no human artifact. That wasn’t a pipe. That was a signal.
That night, I broke my rule. I stood in the bathroom, staring at the open window, watching the black mound of the tip against a bruised purple sky. At 11:23, the whistle blasted, so loud my eardrums ached. And this time, I heard a second sound underneath: a low, grinding rumble, like stone shifting against stone. I leaned out the window, and in the faint glow of a distant streetlamp, I saw it—a dark shape, humanoid but wrong, standing at the edge of the slag heap. It raised an arm, and I realized it was holding a ghostly lantern, swaying side to side. The shape began to move, not walking, but sliding down the hill toward the village, toward my block. A voice, carried on the wind, not quite human, not quite audible, whispered a name I didn’t recognize. But I knew it was meant for me.
I slammed the window shut and fumbled with the lock. The key was still on the sill. I turned it. The whistle stopped abruptly, leaving a ringing silence. But the grinding continued, growing closer. I stumbled back, tripping over the bath mat. And that’s when I saw it in the mirror—a face, eyes like pits, mouth stretched into a silent scream, pressed against the frosted glass of the bathroom window. It was only there for a second, then it was gone. But the grinding stopped. And the night became quiet again.
I didn’t sleep. I called Mrs. Probert, and she answered on the first ring, as if waiting. ‘It found you,’ she said, her voice hollow. ‘They don’t ring the bell for the living. They ring it for the ones who are about to join them. The tip took thirteen souls in ’66. They’re still waiting to be whole.’ I wanted to dismiss her as a mad old woman, but I couldn’t shake the image of that face.
Yesterday, I went to the local library, dug through old newspapers. There it was: the 1966 Aberfan disaster. A coal tip collapsed onto a school, killing 116 children and 28 adults. But at the bottom of the article, a small note: ‘The colliery bell, weighing exactly thirteen pounds, was recovered from the debris, still intact. It has been ringing on its own ever since, though no one can find its source.’ I slammed the paper shut. That night, I didn’t go to the bathroom. I sat in the living room, the window locked, the curtains drawn. At 11:23, the whistle came again, but muffled, like it was inside the walls. Then my phone buzzed. A message from an unknown number: ‘You’re the thirteenth. Come home.’
I’m writing this from my bed, the covers pulled to my chin. The clock just hit 11:22. I can hear the window rattling, the lock straining. And beneath that, a sound I can’t unhear—the steady, rhythmic tapping of something walking up my hallway, one floorboard at a time. The whistle will come in one minute. And this time, I’ll be the one to answer.
