The rain had been drumming against the corrugated metal roof of my cabin since dusk, a relentless percussion that set my teeth on edge. It was a sound I usually found soothing, a white noise that drowned out the pine forest’s whispering, but tonight it felt like a warning. I had been sorting through my grandfather’s belongings, a task I’d postponed for months, and the air was thick with the smell of mothballs and old paper. I found a small, porcelain key, painted with a strange, swirling design, tucked inside a worn leather journal. It was cold to the touch, and I felt a sudden, irrational urge to press it against my palm, which I did. The moment I did, the temperature in the room dropped, and the rain seemed to intensify, lashing against the windows as if demanding entry.
I set the key aside, telling myself it was just my imagination, that the cabin was drafty and the storm was merely a passing squall. I went to the window, peering out into the darkness. The pine trees were skeletons, their branches clawing at the sky. And then I saw the light. A faint, flickering glow, moving between the trunks, too low to be a person carrying a lantern, too deliberate to be a firefly. It was as if the light was crawling, and it was heading toward the cabin. My grandfather had told me stories about this forest, about the things that moved in the spaces between the trees, but I had always dismissed them as the ramblings of a superstitious old man. Now, I wasn’t so sure.
I stepped back, my heart hammering against my ribs. I had locked the door, but I felt a sudden, irrational need to check it again. I did, turning the deadbolt with a click that sounded too loud in the sudden silence. The rain had stopped. The forest was still. And then came the knock. It wasn’t a rapping, but a single, deliberate thud, as if someone had struck the wood with a heavy object. I froze, my hand on the doorknob. I called out, ‘Who’s there?’ but the only response was the echo of my own voice, swallowed by the damp air. Another knock, this one closer, right at the level of my head. I took a step back, my eyes fixed on the peephole, a small, round glass eye that revealed the empty porch.
But the knocking continued, rhythmic now, like a heartbeat. I grabbed the fireplace poker, my only weapon, and inched toward the door. I pressed my eye to the peephole, but the porch was empty. The knocking stopped. I let out a shaky breath, but then I heard a sound behind me—a soft, creaking noise, like the slow opening of a door. I spun around, and there she was. My sister, standing in the middle of the room, her hair plastered to her face, her clothes dripping with water. But she shouldn’t be here. She lived in Arizona, and she had been dead for ten years. I knew her face, the small scar above her left eyebrow from a childhood accident, the way she held her hands, fingers splayed, as if ready to catch something. It was my twin, but not the one who had survived.
I opened my mouth to speak, but no sound came out. She simply pointed at the porcelain key, which I had left on the table. Her finger, pale and wavering, like a reflection in a disturbed pond, directed my gaze. I looked at the key, and I saw that it was glowing, a faint, sickly green. I picked it up, and the moment my fingers touched it, the room spun. When I regained my senses, my sister was gone. But the key felt heavier, and I knew, with a certainty that chilled me to the bone, that it was not a key to a lock, but a key to something else. A key to the forest’s secrets, a key to the presence that had been watching me all along. And the knocking started again, this time from inside the walls. I realized, with a horror that clawed at my throat, that I had left the door unlocked. And the thing that had been trying to get in was now already here.
