The Frequency Between Walls

Marta and I had lived in the old farmhouse for three years, and in all that time, the tiny AM/FM radio on the bathroom shelf had been a faithful companion. It was a relic from my grandfather, a chunky plastic thing with a worn dial that clicked when you turned it past the off position. We only used it during our lengthy showers, to catch the local news or an oldies station, but mostly it sat silent, a dusty sentinel above the toilet.

Last Tuesday, Marta was folding laundry in the hallway when she heard it—a low, guttural hiss, like steam escaping a pipe, but thinner, more deliberate. She paused, listening. The sound was coming from the bathroom. She pushed the door open gently, and there it was: the radio was on, the dial turned just past the click, volume at a whisper. No music, no voices—just that strange, sibilant hiss, as if the air itself was being forced through a tiny gap. I was at work when she called, her voice tight. ‘It’s on again. I swear I turned it off. I even pulled the plug.’

That evening, I examined the radio. The plug was firmly in the socket, the dial set to off. I turned it on, just to test, and it worked fine—static, then a faint crackle of a distant station. I turned it off with a decisive click and left. But at 3 a.m., I woke to Marta’s hand shaking my shoulder. ‘Listen,’ she whispered. From the bathroom, I heard it again: the hiss, now louder, almost like a thousand whispers layered on top of each other, too fast and too faint to make out words. I went in, and the dial had moved on its own—volume now at a quarter, the frequency knob slightly shifted, as if someone had been tuning it.

We decided to unplug it and put it in the basement storage, wrapped in a plastic bag. Marta insisted, and I complied, though I felt a childish dread at the thought of it down there in the dark. For two days, the house was quiet. Then, on Friday, our cat, Percy, started staring at the bathroom ceiling and yowling inconsolably. When I went in, I noticed the radio was back on the shelf, plugged in, the power light glowing a faint red. My blood went cold. I hadn’t brought it up. Marta hadn’t either.

The hiss had become a low, arrhythmic hum, like a distant generator. And then I heard it—a voice, barely there, but unmistakably human. It was saying something in a language I didn’t know, but the cadence was pleading, repetitive. I tried to turn the dial off, but it wouldn’t budge. The plastic felt warm, almost feverish. I yanked the plug, and the radio went silent, but the hum persisted, coming from inside the walls.

Marta begged me to get rid of it—throw it in the lake, burn it. But I was gripped by a morbid curiosity. I carried it to the workshop and pried open the back. Inside, instead of standard circuitry, I found a tangled mess of copper wire, a small crystal that pulsed with a sickly green light, and a piece of paper, yellowed and brittle, with a hand-drawn symbol that looked like a spiral with too many turns. The crystal was warm to the touch, and I felt a sudden pressure in my ears, like being underwater. I dropped it, and the radio crackled to life, emitting a burst of static that sounded like muffled screams.

That night, as we tried to sleep, the house was alive with whispers. They seeped through the heating vents, from the light switches, from the gaps under the doors. Marta held my hand and wept. ‘It’s calling,’ she said, ‘from the between.’ I didn’t know what she meant, but I knew we had to leave. We packed a bag, but when we opened the front door, the hallway outside our house was gone—replaced by a long, dark corridor lined with doors, each one slightly ajar, and from each came a sound I recognized: the radio’s hiss, the hum, the pleading voice. We slammed the door shut, but the knocking began—slow, deliberate, all around us.

I knelt by the radio, which had somehow followed us to the bedroom. I didn’t dare touch it. Instead, I whispered to it, begging it to stop. The dial turned on its own, clicking past the off position, and the volume rose. And then the voice, clear as day, spoke in English: ‘You turned me on. Now you must listen.’ I tried to scream, but no sound came out. Marta was gone—I was alone in the room, the radio on the shelf, the hiss steadily growing into a roar that drowned out my thoughts.

I woke up in the hospital three days later, with no memory of how I got there. The doctors say I was found wandering in the fields, disoriented. Marta hasn’t been seen since. They released me to a small apartment in the city, far from that house. But last night, as I lay in the dark, I heard a faint click from the nightstand. I turned, and there it was: a small, plastic radio, the one from the bathroom, its dial glowing faintly. I reached to unplug it, but my hand stopped. I knew, with chilling certainty, that if I touched it, I would hear her voice—pleading, just like the others. I left it on, and for the first time, I listened.
