When Lena moves into an old tenement, she starts hearing things from the locked attic that no one will explain. One night, she and her friends decide to go up and find out what is really waiting there.
The June air came in through the open window heavy with rain and warm stone. Below, the street lamps turned the cobblestones into strips of dull gold, and the tenement across from Lena's room looked older than the city itself, its brickwork darkened by decades of soot, repairs, and secrets no one seemed eager to name.
She had lived there only three weeks with her younger sister, Klara, yet the building already felt like it had begun to learn their routines. It settled and creaked at odd hours. Pipes knocked in the walls. At night, something moved above them.
The attic was supposed to be sealed. The manager had said so with the tired confidence of someone repeating a story he hoped would end the conversation. But the footsteps kept coming anyway, soft and deliberate overhead, followed by the drag of something heavy across the floorboards and, once or twice, a burst of laughter so low Lena could not tell whether she had imagined it.
She might have dismissed it as nerves if not for Ark.
He lived in the building across the street and always seemed to appear at the wrong moment, a notebook tucked under one arm, his pages crowded with cramped sketches of doors, windows, and symbols Lena could not decipher. She caught him by the entrance one evening and told him about the noises from the attic, expecting a joke or a polite excuse.
Instead, he gave her a crooked smile and said, "It is not an attic. It is more like a floor above."
Before she could ask what that was supposed to mean, he had already crossed the street and vanished into the dark.
By Friday, curiosity had hardened into something sharper. Lena, Klara, and their college friend Michal met in the kitchen with the lights off and the window cracked open for air. No one said they believed the building was haunted. No one said the opposite either. They only sat with the silence between them until Lena stood up, took the small brass key she had found in a drawer left by the previous tenants, and said they were going upstairs.
The staircase to the attic rose in a narrow spine of wood and iron, each step answering with a complaint. The higher they climbed, the colder the air became. By the time they reached the top corridor, the building sounded far away, as if they had stepped out of it and into a pocket of empty space.
At the end stood an old door with peeling paint and a warped frame. Lena slid the key into the lock. It turned too easily.
The door opened on a breath of air so cold it made Klara flinch.
Dust hung in the beam of Michal's torch. Old furniture stood under sheets gone grey with age. Stacked books leaned in unstable towers. And at the far wall, half-covered by a dropped canvas, stood a mirror in a broken frame.
Lena stopped at once.
The glass was marked with hairline scratches, too many to be accidental, too precise to be random. When she looked into it, the reflection took a second to settle. Then she saw herself, Klara, Michal, and the room behind them.
Someone else was in the mirror.
Not in the attic. In the reflection.
Michal lifted the torch higher, and the beam struck the glass hard enough to make the scratches flare white. For a moment the surface seemed to ripple, as if it were not glass at all but water held in place.
Then the ceiling lamp above them flashed awake with a sharp burst of yellow light.
The door slammed shut behind them.
Klara sucked in a breath. Michal swore under his voice. Lena did not move, because something had changed in the mirror again.
A hand was pressed against the other side of the glass.
It was not any of theirs.
From somewhere in the dark beyond the shelves, a whisper slid across the attic, so close it seemed to brush the back of Lena's neck. The mirror trembled. The air around them thinned and vibrated, as if the room itself had begun listening.
And then the hand in the glass slowly lifted, as though whatever stood on the other side had just noticed them.
