It started with a kitchen clock that stopped at 3:13 AM every night, no matter how many times we replaced the batteries. My mother, Elena, and I had lived in the old Marigold Apartments for seven years, in a unit on the fourth floor that smelled of old wood and dust. We were used to the creaks and groans of a building that had seen better decades, but this was different. The clock was a cheap plastic thing we’d hung near the fridge, and every single day, at the exact same time, it would just stop. At first, we laughed it off. ‘Old batteries,’ Mom said. But we changed them, over and over, and it kept happening.
The second anomaly unfolded on a Tuesday evening in October. The wind outside howled through the gaps in the window frames, and Mom was reading a paperback in her armchair while I scrolled through my phone on the couch. Suddenly, the entire apartment went dark. Not just the lights, but the hum of the refrigerator cut out, the red standby light on the TV died, and even the digital display on the microwave disappeared. We sat in absolute, suffocating silence for a beat. Then, from the hallway leading to the bedrooms, we heard a sound like a bag of metal hitting the floor. It wasn’t loud; it was a dense, muffled crash, as if something heavy and full had been dropped onto the carpet.
We fumbled for our phones, but their flashlight apps refused to turn on. Mom whispered, ‘Stay here,’ and moved toward the hallway with a steadiness that surprised me. I followed, my heart hammering. The hallway was pitch black, but Mom found the light switch, and when she flicked it, nothing. Then, as if a switch flipped inside the universe, the lights blazed back on, and we saw them: four objects lying in a neat row on the carpet, right in the middle of the hall. We both stopped. They were old battery-powered lanterns, the kind my father used to keep for camping. They were turned on, their beams pointing up, but the batteries had been removed and placed in a small pile beside them, like someone had carefully disassembled them and left them as an offering.
Mom’s face went pale. ‘Those were Dad’s,’ she said, her voice thin. We had no idea where they’d come from. We’d packed them away years ago, in a box we’d never opened since moving in. But there they were, dusty with time, the metal cases dented. I knelt down and picked one up. It was cold, colder than a piece of metal in a 70-degree apartment should be. Inside the battery compartment, where the batteries should have gone, there was a thin layer of dark, gritty residue, like the kind you’d find at the bottom of an old basement. Mom shuddered. ‘We need to get rid of these,’ she said, and she gathered them all in her arms, even though I could see her hands trembling.
We carried them to the dumpster in the back alley and threw them in. We didn’t speak about it. That night, I barely slept. I kept hearing a faint, rhythmic scratching from the closet, like a mechanical pencil on paper. I told myself it was the building settling.
Three nights later, I was alone in the bathroom, brushing my teeth, when the mirror fogged over from the steam of the shower. I wiped the glass with my hand, and for a split second, I saw something behind me—a dark shape with too many angles, standing in the doorway of the bedroom. It wasn’t a person. It was more like a silhouette cut from the night itself. When I turned, there was nothing there. But the bathroom light flickered once, and I heard the unmistakable sound of a battery sliding into a compartment, a soft click, and then a low hum. I yanked open the bathroom cabinet where we kept our spare batteries. They were scattered, some fresh, some half-used. One was missing. The hum stopped.
My mother started acting strange after that. She’d stay up all night, sitting in the dark, staring at the door. I’d wake to find her pacing the living room, muttering, ‘It’s draining us, it’s draining us.’ She claimed the building was hungry. Then, the third incident: I came home from work to find her on her knees in the kitchen, surrounded by every battery we owned—AAAs, AAs, C-cells, the tiny button ones from watches. She had them arranged in a spiral on the floor, and she was chanting something under her breath, words I’d never heard. When I approached, she looked up, and her eyes were rimmed red, not from crying but from lack of sleep. ‘It wants the charge,’ she whispered, ‘It brought the flashlights to remind me. Your father, he knew.’
I tried to get through to her, to pull her away from the spiral, but she grabbed my wrist with a strength that didn’t match her wiry frame. ‘We took them away,’ she said, her voice breaking, ‘But it doesn’t forget. It made its own.’ And that’s when I remembered the residue in those flashlight compartments—it wasn’t rust. It was dried, black battery acid, but it wasn’t from any battery I’d ever seen. It smelled of ozone and something else, something sweet and rotting.
The final thing happened last night. The building’s power went out again, but this time, the blackout spread to the whole street. In the dark, I heard Mom’s footsteps walking down the hallway, slow and deliberate. When the lights flickered back on, she was standing in front of the open closet, and the four flashlights were on the floor again, right where we’d found them, but each one was glowing with a sickly orange light. The batteries were back inside—but they weren’t household batteries. They were fingernail-sized, black, and they hummed with a low frequency that made my teeth ache. Mom picked one up, and even from across the room, I saw her wrist bulging as if the light was pressing against her skin.
I screamed at her to drop it, but she didn’t. She just smiled and said, ‘It’s been waiting. It’s been feeding on us, on our life, on our energy, for seven years. And now it’s learned how to seed itself.’
She turned the flashlight toward me, and in that harsh orange beam, I saw the truth: her shadow on the wall was not her shadow. It had long, thin arms, and it was reaching toward me with hands that had too many fingers. I didn’t stay to see more. I fled the apartment, ran down four flights of stairs, and burst out onto the street, where the air was cold and the streetlights were dead. I didn’t look back until dawn.
Now I’m sitting in a coffee shop across town, writing this. I haven’t seen Mom since. I tried to call her, but her phone goes straight to voicemail, and the signal is always just out of reach. I can’t go back. But this morning, when I reached into my coat pocket to pay for my coffee, I found a small, black battery—finger-sized, humming softly in my palm. I dropped it on the table, and the barista asked me if I was okay. I wasn’t. I am not. That battery is in the trash now, but I can still feel its charge, a subtle pressure in my chest, like something a breath away from activating.
The building is still there, waiting. And I’m starting to think it has a plan for me.
