After a stormy Friday morning at school, Veronica, Krzyś, and Igor discover a hidden door in the old art room. What waits beyond it is impossible, shifting, and definitely not empty.
It was the last Friday of September, and the storms had left the city dripping and half-asleep. The school still smelled of wet coats, old polish, and the damp that always seemed to rise out of the corridors after rain. Veronica arrived early, as usual, and wandered the nearly empty hallways, waiting for the noise of lockers, voices, and footsteps to wake the building up.
Something about the school had felt wrong for weeks. The lights on the second floor sometimes flickered for no reason. A few classroom doors had begun to gather a thin, grey dust, as if nobody had touched them in years. No one said anything about it, but Veronica had noticed. She had noticed all of it.
That morning, she found herself climbing to the third floor, where she rarely had any reason to go. The old art room door hung slightly ajar. It should have been locked. Mrs Marczewska had retired months ago, and everyone had treated the room like a forgotten corner of the school ever since.
She was still staring at the door when Krzyś slipped up beside her.
“What’s in there?” he whispered, eyes bright with the kind of excitement that always meant trouble.
Before Veronica could answer, Igor appeared from the next classroom and joined them, breathing hard as if he had been running.
None of them spoke for a second. Then, almost at the same time, they pushed the door open and stepped inside.
The room was colder than the corridor. Dust blurred the tall windows. The floor complained under their shoes. Across from them was the plastered-up wall, the old sink, the paint-splattered shelves.
And beside the shelves stood a door.
It was dark wood, smooth and polished, completely out of place. So out of place that Veronica’s stomach tightened the moment she saw it. She knew every room in the school. She knew every hallway, every storage closet, every blind corner. That door had never been there before.
“Did someone install it?” Igor asked, reaching for the handle.
The metal was cold enough to sting.
Veronica stepped closer, hearing something she could not place at first - a faint pulse, almost like breathing, almost like a heartbeat coming from the other side.
Then the door opened.
There was no classroom behind it, no storage room, no dusty cupboard. Only a narrow spiral corridor, lit by a strange pale glow that seemed to throb in time with her pulse. The walls shimmered with patterns that shifted whenever she blinked, as if they were moving underneath the paint.
A soft bang echoed behind them.
They spun around. The door had slammed shut on its own.
The corridor ahead flickered once, and the light deepened. Somewhere inside that pulsing brightness came a sound like children whispering just out of reach. The three of them stood frozen, listening, as something began to move toward them from the end of the passage.
