Three teenagers sneak to an abandoned bridge at midnight, where a strange sound in the fog leads them to a hidden tunnel and something waiting in the dark.
By midnight, the town had gone strangely still. Fog pressed against the windows, softened the streetlights, and swallowed the old bridge until only its rusted railings and the black ribbon of the river beneath it were left in view.
Lena was the first to climb over the loose stones at the riverbank. Michael followed, his torch shaking in his hand, while Igor kept glancing back at the road as if he expected someone to shout their names and drag them home. For weeks, the same rumour had been circling the school: voices under the bridge, a clatter of metal, a low laugh that came and went with the mist. Nobody had proven anything. Nobody had even tried. Lena was tired of listening to stories whispered in the hallway like they were facts.
"See?" she said, forcing a grin. "Nothing here."
Igor crossed his arms, but he did not answer. Michael swung the torch beam along the river, then up at the underside of the bridge, where water dripped steadily from the beams. For a few seconds, there was only the hush of the current and the distant bark of a dog somewhere in the town. Then Lena lifted a hand and froze.
"Do you hear that?"
At first it was so faint Michael thought he imagined it. A thread of sound, almost swallowed by the fog. Not quite singing. Not quite speech. It rose and fell under the bridge, thin as breath against glass, and somehow it felt familiar in the worst possible way.
Igor stepped closer to Lena. "Stop messing around."
"I'm not. Listen."
The sound came again, clearer this time, and Michael felt the hair on the back of his neck rise. He pointed the torch toward the shadow beneath the nearest support pillar, and the beam caught on something wet and pale. Not a body. Not a face. Just a strip of stone wall slick with river water and a gap behind it where there should have been solid ground.
Michael blinked. The gap had not been there a moment ago.
"That wasn't there before," he said.
He moved closer, the torchlight wavering across the narrow opening. It was a tunnel, barely wide enough for one person to squeeze through, its edges rough and old as if it had been hidden for years. Cold air breathed out of it, carrying that strange half-song and the smell of mud and iron.
Igor swore under his breath. Lena did not move, but her eyes were fixed on the darkness beyond the tunnel, bright with the kind of curiosity that made caution useless.
Then the singing stopped.
In the sudden silence, a sound answered from inside the tunnel: a long whisper, slow and deliberate, as if someone on the other side had been waiting for them to come close enough to hear.
Lena took one step forward.
And from the black mouth of the tunnel, something shifted and began to emerge.
