After winter break, a hidden stairway leads three students onto the roof, where their new history teacher is waiting with a map and a question.
I had never thought of my school as a place where anything unexpected could happen. It was just the same long corridors, the same chalk dust in the air, the same lockers slamming shut like impatient doors in a bad mood. Every day blurred into homework, pop quizzes, and the slow, dragging countdown to the next test.
That changed on the first Monday after winter break, when we got a new history teacher.
Mr Borkowski did not look like the others. He wore a dark turtleneck instead of a suit, and round glasses that caught the light in a strange, silvery way. He spoke quietly, but the room always went still when he did. Even the boys in the back row stopped whispering. He told stories as if he had actually been there, and when he talked about the past, it stopped sounding dead and started sounding dangerous. Nobody knew where he had come from, and the teachers who did know were suddenly very careful whenever his name came up.
After lessons, I stayed behind with Maja and Michael.
Maja noticed everything. She could spot a hidden pattern in a timetable, a lie in someone’s face, a clue in a scribbled note. Michael could take apart almost anything and put it back together before the owner even realised it had been touched. I was usually the one who tried to keep them from doing something stupid.
That afternoon, we were heading through the oldest wing of the school when Maja stopped so suddenly I nearly walked into her.
At the end of the corridor was a door we had all seen before, but never really looked at. A faded sign hung on it: STORE ROOM. The door was cracked open a few centimetres.
Maja lowered her voice. “That’s never open.”
Michael was already digging through his backpack. A second later, he pulled out a torch and grinned like this was exactly the kind of problem he had been hoping for. “Then maybe we should see why.”
We should have left it alone. Instead, we stepped inside.
The room was dark and smelled of dust and old paper. Shelves crowded the walls, half-buried under broken chairs, boxes, and stacked atlases. Then Michael swept the torch across the far corner, and Maja grabbed my sleeve.
There was a gap behind the shelves.
At first I thought it was just shadow, but one of the wall panels stood slightly proud of the others, as if someone had pressed it and never bothered to close it properly. Michael pulled the shelves aside. The panel moved under my hand.
Behind it was a narrow staircase leading up.
None of us spoke. The stairs twisted into darkness, and at the top waited a heavy metal door covered in etched patterns that caught the torchlight like scratch marks.
My heart was beating too fast by the time I pushed it open.
We stepped out onto the flat roof of the school.
The wind hit us first. Then the sight of Mr Borkowski standing in the middle of the roof with a large leather map spread open in his hands, as if he had been waiting for us all along. The setting sun burned behind him, turning his glasses into two bright, unreadable sparks.
For one frozen second, no one moved.
Then he looked up.
His face changed when he saw us, not with surprise, but with recognition. He folded one corner of the map, raised a hand, and said in a low voice, “I was wondering how long it would take you.”
The wind slipped over the roof, and Maja tightened her grip on my arm.
Mr Borkowski’s eyes moved from one of us to the next, calm and sharp at the same time.
“Are you ready,” he asked, “to take the next step?”
