Maks and Lena spot a strange light in the old school basement and follow it into a hidden corridor. But the door at the end is waiting for something.
Maks pressed his nose to the dusty basement window and stared out into the schoolyard. Evening was sliding in fast, and the oldest wing of the building stood in the fading light like it was holding its breath.
Lena nudged him with her elbow. "Are you absolutely sure you saw it?"
Maks lowered his voice. "A light. Down in the basement. I saw someone moving past the window."
Lena frowned, then glanced toward the dark doorway at the bottom of the stairs. She believed in strange things more than most people did, but even this made her skin prickle.
"Someone shouldn't be down there," she whispered.
"Exactly," Maks said.
They stood there for a moment, listening. The school had gone quiet for the day. No voices in the hallways. No clatter from the gym. Just the faint hum of the lights above them and the soft creak of the building settling into the evening.
Then another sound reached them. A low scrape.
Lena caught her breath. Maks looked at her, and neither of them said what they were both thinking: if there was anyone in the basement, they were already too close to the thing they were not supposed to find.
Side by side, they moved along the wall until they reached the heavy basement door. The paint on it was cracked and flaking, and the brass handle was cold enough to sting Maks's fingers when he touched it. He pulled out the small torch he always kept in his pocket, then looked at Lena.
She gave one quick nod.
The door groaned as they opened it.
Cold air rolled out from below, sharp and damp, carrying the smell of dust and old stone. The stairs were narrow and steep. Each step answered them with an echo that seemed to race ahead into the dark. Maks shone the torch downward, but the beam only made the shadows jump.
Halfway down, Lena caught hold of the banister. "This place is creepy," she murmured.
"You can still go back," Maks whispered, though he did not mean it.
Lena rolled her eyes, but her hand tightened on the railing.
At the bottom, the basement opened into a cluttered room full of forgotten chairs, broken boxes, and shelves bent under the weight of years. The torch beam slid across peeling walls and a water stain shaped like a dark map. Then Maks stopped so suddenly that Lena bumped into his shoulder.
"There," he breathed.
Behind a huge cupboard pushed against the far wall, something gleamed.
They crept closer. It was a steel door, clean and bright, as if it had been installed yesterday. It looked wrong in the middle of all that decay, too new, too neat, too carefully hidden.
Lena stared at it. "I've never seen that before."
Maks reached for the handle. It turned at once, almost too easily, and the door clicked open.
Beyond it was not another room, but a narrow corridor washed in a faint green light that seemed to pulse at the far end. Strange marks covered the walls: lines, symbols, and sketches that looked half drawn and half scratched in a hurry. The air smelled damp and metallic, and underneath that was something else, something that made Maks's stomach tighten.
Something waiting.
They took one step inside.
Then another.
The corridor led to a second door, taller than the first and completely plain except for one thing: a round hollow in the centre, shaped like it was made for a hand, or a key, or something they did not have.
Lena swallowed. "What is that?"
Maks lifted the torch.
From behind the door came a soft rustle, as if someone on the other side had just shifted closer to listen.
