The Static Between Frequencies

I’m sitting in my sister’s new house, a glass box of a place she had built on the edge of a reclaimed marsh. The architect called it ‘minimalist modern,’ but to me it feels like living inside a fishbowl, all that glass and pale wood. I’m here to watch her cat, a fat, indifferent tabby named Marmalade, and to water her collection of orchids. The whole thing was supposed to be a favor, a quiet week away from my cramped city apartment. Now, I’m not sure I’ll make it through the night.

It started two days ago. I was in the kitchen, pouring a glass of water, when the radio—a sleek digital thing she keeps on the counter—started tuning itself. It cycled through static, white noise hissing like a nest of snakes, then cut to a dead frequency, just that hollow, empty sound. I turned it off. Then, out the window, I saw it: a patch of reeds at the edge of the marsh flattened as if something heavy pressed them down, moving in a straight line toward the house. There was no wind. The cattails stood still everywhere else. The line stopped at the foundation, paused, then started moving along the wall, heading for the corner where the living room meets the sunroom. I watched it go, my heart doing a stupid little tap against my ribs. It reached the corner and vanished, like a shadow folding into the house’s geometry. I told myself it was a trick of the light, a thermal thing from the heating vents. But I checked the lock on the sliding door twice before I left for work.

Yesterday, it got worse. I was in the office, a small room she uses for telework, with a window that looks out over the back patio. I was typing an email when I felt it: a presence. Not a sound, not a smell, but a weight in the air, a pressure behind my right shoulder, as if someone stood just outside the doorframe, watching. I turned. The hallway was empty. Marmalade was asleep on the guest bed, visible through the open door, his sides rising and falling. The door to the office was open, but I knew it had been closed—I remembered sliding it shut because the heater was blowing cold. I closed it then, slowly, and locked it. The presence lifted, but for the rest of the afternoon, I caught movement at the edge of my vision: the shimmer of the glass, the way the light bent around the corner of the desk. I convinced myself it was exhaustion. I’d been sleeping badly.

Then last night, I decided to test something. I set up my phone to record the hallway from a bookshelf, and I left it running while I made dinner. I reviewed the footage later, even though some part of me dreaded it. For the first hour, nothing but the occasional flicker of the hallway light and Marmalade padding by. Then, at 11:47 PM, the cat stops. He’s midway down the hall, and he freezes, ears swiveling. His fur stands up. He stares at the closet door at the end of the hall, the tiny one the contractor supposedly built over a plumbing access. It’s closed, but in the recording, I can see the knob turn slightly. Just a fraction, a quarter of a turn. And then—nothing. But the cat won’t move. He backs away slowly, tail low, and then scampers into the kitchen out of frame. I stopped the recording. The house felt different then, the air denser, as if something was breathing with me. I couldn’t sleep. I lay in bed, staring at the ceiling, and the radio in the kitchen—which I had unplugged—hummed alive with a low, electric thrum that I could feel through the floorboards.

Tonight, I’m camped out in the living room, my laptop open, trying to justify this all to myself. I’m writing this as a record, a way to keep my mind tethered. The house is not old—three years at most, same as my sister. But I’ve begun to notice things: the floorboards have settled in strange patterns, warped in places that shouldn’t have moisture, and there are scratches on the baseboards in the hallway, deep grooves like something dragged its nails from the closet to the kitchen. My sister never mentioned these. She’s not the type to let that slide. And the cat—Marmalade—hasn’t come out of the guest room in hours. He’s hiding under the bed, and when I went to check on him, his eyes were dilated, pupils huge and black, and he hissed at me, a sound I’ve never heard from him. That wasn’t like him. He’s a lap cat. He loves people.

Right now, it’s 2:14 AM. I just heard the sliding door to the patio glide open. It didn’t make the familiar squeak—it moved smoothly, as if oiled. I know I locked it. I double-checked after the reeds incident. I got up from the couch, my heart in my throat, and turned to look. The door was open a crack, and outside, the marsh was dark, but I could see a shape out there. It wasn’t human. It was tall, thin, like a scarecrow made of reeds, swaying slightly. It didn’t have a face—just a smooth, dark surface where a face should be. It stood at the edge of the patio, just beyond the light spill, and it was watching me. I could feel its gaze, even without eyes. And then, as I stared, it took a step forward. Not a leg movement—it glided, as if the reeds themselves were moving. I backed up, and my hand hit the radio on the shelf. It was still unplugged, but it crackled to life, a burst of static that startled both me and the thing outside. The shape paused. Then it turned and melted back into the marsh, dissolving into the tall grasses.

I’m sitting here now, my back to the wall, the sliding door locked again (I made sure). The static from the radio has stopped, but I can still hear a faint hiss, like a distant signal. The cat is still in the other room. I think it’s coming back. I feel it at the edge of my awareness, a pressure building behind my eyes, and I know that if I turn my head just slightly to the right, I’ll see it standing in the corner of the living room, where the wall meets the ceiling, a shadow that doesn’t align with the light. I won’t turn. I’m going to write until my battery dies, because I know that as soon as I stop, as soon as the screen goes black, I’ll have to face it. And I don’t know if I can.

There. The cat just yowled. A long, terrible sound, like a creature being skinned. It came from the guest room, but it wasn’t the cat—I’ve heard that sound before, in a documentary about foxes. It was mimicry. And now I hear footsteps in the hallway. Slow, deliberate. The floorboards creak under a weight that isn’t mine. The light in the hallway flickers, and through the gap under the door, I see the shadow of something pass. It doesn’t have a human shape. It’s too wide, too low, like a thing that walks on all fours. It stops in front of the door. I can see its silhouette against the light from the kitchen. And then, the doorknob begins to turn. I locked it, but I hear the lock click open. The door is opening. I’m typing this as fast as I can, but my hands are shaking. It’s in the room now. I can feel its presence, a coldness spreading across the floor. I don’t look up. I don’t look up. I just hear the radio in the kitchen sputtering to life, and a voice that sounds like my own, but wrong, saying, ‘I’ve been here all along.’
