The Last Cartridge

The house at 33 Marrow Lane was a creature of damp and creaks, and I had learned to hate it long before my grandfather passed. He died in the autumn, the same week the boiler gave out, and the cold seemed to seep from the walls themselves. At fifteen, I was already lost, but his death carved a hollow in me I couldn’t name. My mother moved through the rooms like a ghost, and the silence grew heavy enough to choke.

I found the book in the attic, hidden beneath a floorboard that had warped with age. It was bound in cracked leather, the pages brittle and yellowed, filled with diagrams and symbols that made my skin prickle. I didn’t understand half of it, but I recognized a promise: a way to reach the dead. The instructions were meticulous, demanding blood, a candle made of black wax, and a photograph of the departed. I had all three.

Three weeks after the funeral, I decided to try. I locked myself in the back study, the room my grandfather called his ‘workshop,’ where he kept his tools and the old radio he used to listen to static. I drew the symbols on the floor in chalk, exactly as the book described, and placed the candle at the center. My grandfather’s photograph stared up at me, his eyes kind, his mouth a thin line. I cut my palm with a letter opener, let the blood drip onto the paper, and spoke the words I had memorized.*Come back to me. Find the door I’ve opened.*

The candle flickered, then burned steady. The radio, which had been silent for years, crackled to life. Static, then a low hum, then a voice—thin and distant, like something speaking from the bottom of a well.

‘Thomas.’

My heart seized. It was his voice, exactly. I answered, my throat tight. ‘Grandpa? I’m here. I want you to come back.’

There was a long pause, and the static grew louder, like rain on a tin roof. Then the voice came again, but colder. ‘You shouldn’t have opened that door, boy. There are things that listen. And I’m not alone.’

The candle guttered. The symbols on the floor seemed to writhe, and the air turned sharp with the smell of ozone and rot. I stumbled backward, but the door to the workshop slammed shut, and the lock clicked. A deep, resonant sound—like a heartbeat from the walls—began to pulse through the room. I threw myself against the door, but it wouldn’t budge. Through the crack under the door, I saw the light in the hallway dim, and a figure began to take shape—tall, angular, with too many joints.

‘You let me in,’ it said, not in my grandfather’s voice, but in a hundred voices layered together. ‘I will take his place.’

The panic was absolute. I clawed at the floor, reached for the book, and ripped out a page. I burned it in the candle flame, shouting the words the book said were for closing doorways. The figure at the door paused, tilting its head. ‘That will not work. You used the wrong key.’

But I had another page, one I hadn’t read yet. It was the last page, bound in red thread. I tore it free and read it aloud: a binding, a warding, a summoning of my own. The words felt like knives in my throat, but I forced them out, and the floor beneath me splintered. A crack opened, black and yawning, and a cold wind blew up from it. The figure screamed—a sound that tore the wallpaper—and something yanked it down into the gap. The crack sealed with a snap, leaving only ash on the floor.

I woke up hours later, sprawled on the carpet, my hand bleeding and the book smoldering beside me. My mother found me there and took me to the hospital, but I never told her what happened. I stopped trying to contact the dead. I burned the book and buried the ashes in the backyard.

But at night, sometimes, I hear the radio in the workshop click on. I hear a slow, deliberate breathing, not my own. And I remember the last page of that book, the one I read aloud, which spoke of a door that must never be opened, and a price that must always be paid. I don’t know what I summoned into that crack, but I know it was not my grandfather. And I know it is still there, waiting for me to make the same mistake again.

I’ve since moved away from that house, but the memory clings like mildew. I see the figure in reflections, standing just behind my shoulder. I hear it in the hum of my refrigerator. And I know that the door I opened can never truly be closed, only held shut by my own will. The last cartridge of that story is nothing but a reminder: there are doors that should never be opened, and there are things that answer when you knock.

I keep the door locked now. I keep the light on. But the house at 33 Marrow Lane is still there, and it still remembers me. And somewhere in the dark, something remembers me too.
