The Concrete Hollow

My best friend Anya and I were thirteen the summer I finally told her about the house on Mallow Lane. Not the new house, the rental my parents had dragged us to after my dad’s job transfer, but the older one—the one with the basement that breathed. I’d never told anyone outside my family before, mostly because my mom would roll her eyes and my little brother would make ghost noises. But Anya was different. She listened with wide eyes and a tiny, believing frown, and when I finished, she whispered, ‘You really think it’s haunted?’ I nodded, and she said, ‘Cool.’ That word, ‘cool,’ made me feel lighter than I had in months.

So when my parents decided to finish the basement into a family room—drywall up, but the floor still raw concrete and scattered with boxes and old toys—I saw my chance. I begged for a sleepover, and Anya convinced her mom to let her stay. We set up our sleeping bags on a bare patch of floor, surrounded by paint cans and a dehumidifier that hummed like a sleeping animal. We talked about boys, about the upcoming school dance, about anything but ghosts. I told myself nothing would happen. It never did on demand.

Around midnight, the power flickered. The dehumidifier whirred to a stop, and the silence that followed was thick, like wet cloth. Anya giggled nervously and said, ‘Your house is so dramatic.’ I laughed, but my skin prickled. The basement light was a single bulb on a pull cord; it swung slightly, casting sliding shadows. Then I heard it—a soft scratching from the corner where the old furnace stood, its metal side hidden behind a stack of dusty board games. I told Anya it was just a mouse. She didn’t look convinced.

The scratching grew louder, rhythmic, like nails on a chalkboard. It stopped abruptly, and then a low, guttural sound rumbled from the furnace—a groan that seemed to vibrate through the concrete floor. Anya grabbed my arm. ‘What was that?’ she whispered. I shook my head, but I knew. It was the same sound I’d heard from my bedroom ceiling at night, a sound I’d convinced myself was pipes.

The light flickered on and off in a stutter, and in the darkness between, I saw something—a dark shape stretching from the furnace, indistinct but wrong. When the light came back, it was gone. The air turned cold, and our breath clouded. ‘We should go upstairs,’ Anya said, but her voice trembled. I wanted to agree, but my legs felt glued to the floor. The groaning returned, louder, and now it formed words—or something like words. It said, ‘Let me out.’ My blood turned to ice.

I forced myself to move, grabbed Anya’s hand, and we scrambled for the stairs. But the stairs were gone. In their place was a blank wall of concrete, smooth and impossibly new. We spun around. The room seemed larger, the walls farther away, the ceiling higher. The dehumidifier hummed again, but it sounded like a heartbeat. Anya started to cry. I pounded on the concrete, screaming for help, but no sound came back—not an echo, not even the thud of my fists.

The scratching returned, closer now, from the shadows at the edge of the light. In the dim, I saw a figure—small, crouched, childlike—crawling toward us with an unnatural gait, its head tilted too far sideways. It spoke in that same groaning voice, but now it was a whisper: ‘I was waiting.’ And I looked at Anya, and behind her, the concrete floor was rippling, like water, and there was nothing solid left to stand on. We were in the hollow, and the hollow was hungry.

I woke up in my own bed, sunlight streaming through the blinds. My mom called me down for breakfast. Anya was gone, and no one remembered her ever being at the house. But under my bed, I found a small, painted wooden block with a single letter scratched into it—’A.’ And when I touched it, I heard the groaning again, coming from the floorboards, and I knew: the house had taken her, and it wanted me to come back.
