The storm had passed over the city, but the school was still empty. The film club had dragged on, so only Maja and Cuba remained. The fluorescent light blinked on and off. The lady usher had already left. Kuba's phone showed three per cent battery. - Great - he muttered. - Without electricity, we won't give the camera away. Maja walked over to the table with the cables. Suddenly, the clips on the table vibrated and dripped onto her hand. Startled, she jumped away. The screws rang on the floor, as if calling her name. - Did you see? - She asked quietly. - You attracted it,' said Kuba, all too loudly. - Like a magnet! Maja tried again. She concentrated. The camera tripod moved and slid up to her knees. She felt it like a slight tingling in her fingers. Every metallic trinket was like a thread she could pull. - 'Why don't we unlock the generator? - Cuba suggested. - It takes a key from the warehouse. They ran down the corridor, holding on to the light from the phone. The door to the storeroom was ajar, but the key was gone. In its place lay a broken lanyard and two silver screws. From the ceiling came a long, high-pitched sound, like music from a pipe. - Can you hear it? - Maja asked. The sound led them under the ventilation grille. Something flashed inside, like a tiny mirror. Maja reached out her hand. The screws at the grille trembled and lifted, one by one. The air grew cool, smelling of rain and dust. - Just gently,' whispered Kuba. - 'There might be...' Maja pulled a metal thread, as if fishing a fish out of the shadows. Something heavy shifted in the depths, the clack of a lock rang, and then from the darkness came their short, metallic... answer.
