The Knocking Pattern

The first time I saw the girl, she was standing at the end of the corridor, her back to me, her hair a dark curtain. I thought she was a new tenant, someone from the third floor, but when I called out, she didn’t turn. She just stood there, perfectly still, and then she was gone, as if she’d never been. That was a week before the knocks started.

I live in a converted factory, a labyrinth of exposed brick and steel beams, where the old freight elevator still rattles like a dying man’s cough. The hallways are long and dim, and the building has a way of amplifying sounds—the drip of a pipe, the groan of settling concrete—so I’ve learned to ignore the usual noises. But this was different. It started on a Tuesday, three soft knocks on my door, polite but insistent, like a neighbor asking to borrow sugar. When I opened it, no one was there. I checked the corridor, the stairwell, even the freight elevator, but it was empty.

That night, I couldn’t sleep. I lay in bed, watching the strip of light under my door, waiting. Just past midnight, the knocks came again—three of them, same rhythm, same spot on the wood. I threw the door open, heart pounding, but the hallway was empty, the lights flickering slightly. I felt a draft, cold and smelling faintly of dust and something sweet, like old perfume. I walked to the end of the corridor, past the other doors, and that’s when I saw the girl again, this time in the stairwell, her face half in shadow. She was younger than I’d first thought, maybe sixteen, wearing a faded floral dress that looked like it belonged to another era. She mouthed something I couldn’t hear, and then she turned and disappeared down the stairs.

I told Adam about it the next day. He’s the super, a gruff man in his fifties who’s seen more than he lets on. He listened, his jaw tight, and then said, ‘It’s the night of the 18th you should worry about.’ I asked what he meant, but he just shook his head and handed me a key to the basement. ‘There’s something you should see,’ he said. The basement was a cavernous space, filled with old machinery and boxes of forgotten belongings. In the far corner, behind a sheet of plastic, was a small room that had been sealed off. Inside, there was a bed, a chair, and a wall covered in carvings—hundreds of scratch marks, like someone had counted days, or hours. On the floor, a faded photograph of a girl in a floral dress.

I couldn’t sleep that night. I kept thinking about the carvings, the photograph, the way Adam had looked at me. And then, at 3:33 AM, the knocks came again, but this time they were different—three knocks, a pause, then one. I felt a cold settle in my chest. I remembered the date. It was the 18th. The anniversary. I opened the door, and the girl was standing there, her eyes dark and hollow, her mouth open in a silent scream. She raised her hand and knocked on the air three times, then once. And suddenly I understood: she wasn’t knocking to be let in. She was knocking to be let out.

I don’t know how long I stood there, frozen, as she pointed down the corridor toward the basement stairs. I knew what she wanted. I think I knew from the moment I saw the carvings. So I went. I took the key, I walked through the basement, I opened the sealed room, and I saw the marks on the wall with new eyes. They weren’t days. They were decades. And in the center of the floor, where the bed had been, was a thin crack in the concrete, and from it came a sound—soft, rhythmic, like three knocks and a pause. I dropped to my knees and pressed my ear to the crack, and I heard breathing. And then, a voice, barely there, said: ‘You can let me out.’

I should have left. I should have called someone. But the girl was behind me, her hand on my shoulder, and her touch was like ice. I dug my fingers into the crack and pulled. The concrete gave way like wet clay, revealing a hole, and from that hole climbed a figure—a man, gaunt and pale, with the same dark hair as the girl. He smiled at me, and I saw that his teeth were filed to points. ‘Thank you,’ he said, his voice like gravel. ‘She’s been keeping me in here for a hundred years.’ I looked at the girl, and she was crying—not tears of joy, but of fear. The man stepped past me, and as he did, he touched the girl’s cheek gently, and she dissolved like ash. Then he turned to me and said, ‘You shouldn’t have let me out.’

I backed away, but my legs wouldn’t carry me. He came closer, and I could smell that sweet perfume again, but now it was cloying, rotting. ‘Every 18th of November,’ he said, ‘she tries to warn someone. But no one ever understands the pattern. Three knocks, pause, one. It’s not a code. It’s a name—you see, my name is November. And she was the only one who ever knew how to keep me in.’ He reached out, and his fingers were long, too long, and I couldn’t scream as he wrapped them around my throat. But just as the blackness closed in, I heard the girl’s voice, faint, forgiving: ‘I’ll be waiting for you.’
