The Hollow Between Walls

I have always been a rational man, a man of numbers and ledgers, which is why my current predicament gnaws at me like a rat in the walls. My name is Elias Thorne, and I am a retired actuary living in the old Meridian Flats, a sprawling apartment complex built in the 1920s and left to rot until a developer bought it on the cheap. Now it’s a maze of cramped units and long, windowless corridors that smell of damp plaster and dust.

My unit is on the third floor, at the end of the west wing, where the building’s shadow falls even at noon. I live with my niece, Marisol, her husband, Victor, their two children, and my younger brother, Samuel. Six of them in total, and I alone see what crawls out of the dark corners. They think I’m losing my mind. Perhaps I am. But I know what I’ve seen.

It started three weeks ago, not long after I found a loose panel in the corridor wall. The panel is behind a radiator, just past my door. I noticed it because of a draft, a cold breath that seemed to seep from the cracks even on warm days. When I pried it open, I found a hollow space, not a pipe chase or a crawlspace, but a narrow, vertical shaft that went down into the building’s foundation. The air that rose from it was stale and carried a faint, sweet odor, like rotting honey.

I told no one, of course. I didn’t want to alarm the family, and I was certain it was just an old ventilation duct. But that night, I heard it for the first time: a soft, rhythmic scraping from within the wall, like nails dragging along plaster. I pressed my ear to the panel and listened. The sound stopped, and I felt a presence, a weight on the other side, as if something was listening back.

Since then, I’ve seen it. It appears only to me, usually in my peripheral vision, a tall, thin shape that seems to be made of the shadows themselves. It stands at the end of the corridor, where the light is weakest, and watches me. When I turn to face it, it’s gone, but I can feel the cold spot where it stood. During the day, it sometimes appears as a flicker in the corner of my eye, a silhouette that disappears when I focus. I’ve tried to convince myself it’s a trick of the light, a symptom of my aging eyes, but I know better.

My family has noticed my distraction. Marisol has a worried look on her face when she sees me staring at blank walls. Victor asks if I’m sleeping well. Samuel, my brother, who has always been a skeptic, just chuckles and says I need a hobby. I haven’t told them about the thing or the hollow wall. They would think I’m senile. And perhaps I am, but I can’t shake the feeling that this is connected to something old, something I can’t explain.

Last night, I decided to investigate the shaft. I waited until the family was asleep, then I took a flashlight and a mirror on a stick, and I opened the panel. The shaft was darker than pitch, and the smell of decay was stronger. I angled the mirror to see inside, and at first, I saw nothing but the crumbling brick of the building’s core. But then, I saw a pair of eyes, pale and almost translucent, staring back at me from a recess deep within. They blinked slowly, and my blood went cold.

I slammed the panel shut and leaned against the wall, gasping. The eyes had been unnaturally wide, and they had a knowing look, as if it had been waiting for me. I spent the rest of the night in my room, the lights blazing, clutching a brass paperweight. I heard the scraping again, this time from my bedroom wall, just behind my headboard. It went on for hours, until dawn, when it finally stopped.

Now, it is midday, and the family is out. I stand before the panel once more, my heart pounding. I have to know what it is. I have to find a way to stop it. I’ve read about such things in old books: entities that attach themselves to a place, feeding on the fears of those who dwell there. But I never believed. Now I have no choice.

I open the panel again, and this time, I shine the light directly into the shaft. The eyes are there, closer than before, and I can make out the outline of a face, gaunt and elongated, with a mouth stretched into a silent scream. It doesn’t move, but it seems to be drawing me in. The smell is overwhelming. I feel a cold hand press against the back of my neck, and I jerk away, hitting my head on the radiator.

I stumble back, panting. The eyes are still watching, unblinking. I know I have to seal the shaft, to keep it from getting out. I fetch a hammer and some nails, and I board up the panel, layer after layer of wood and plaster. When I’m done, the corridor is silent, but I can feel the presence, waiting behind the wall.

As I turn to go, I notice a small crack in the plaster near the floor, a hairline fracture that wasn’t there before. From it, a wisp of dark mist curls out, forming a thin tendril that reaches toward me. I back away, and the tendril retreats, as if it can’t cross the threshold of my door. I step into my room and close the door, leaning against it.

For a moment, there is quiet. Then, from within the hollow between the walls, I hear a soft, mocking laugh. It is the sound of something patient, something that knows my family’s routines, my habits, my fears. I realize that sealing the panel won’t help. It will find a way out, whether through the pipes or the floorboards. And it will not stop until it has claimed me, as it has claimed others before me.

I look around my room, at the familiar furniture, the family photos on the dresser. I wonder if I should tell Marisol, even if she thinks I’m insane. But then I hear the scraping again, coming from inside my own closet, and I know that the hollow is not just in the walls. It is everywhere, and it is closing in.

I sit on my bed, the paperweight in my hand, and I wait. The sun is setting, and the shadows in the room are growing long. I know that tonight, when the family is asleep, I will have to make a choice. I will have to face the thing in the hollow, or let it take me as it took the others. Either way, this will be my last night in the Meridian Flats.

I only hope that when they find my body, they will understand that I was not crazy. I was just the only one who could see the hole in reality that the building was built over. And now, it has seen me too.
