The rain drummed against the roof of the city library until the windows trembled. Iga and Olek hid in the map reading room, behind a bookcase. Mrs Renata coughed at the counter and counted the pages of the catalogue. She was about to say when the storm would pass, but time was running out. The door to the storeroom was a hand's width apart. Olek whispered: "We'll just have a look and then come back, agreed, Iga?" Inside it smelled of dust, glue and distant water. On the wall stood an old cabinet with flat drawers. The seventh drawer squeaked and slid out a piece by itself. Iga grabbed the brass handle, very slowly, carefully. On the map was their Market Square, but the park was turning into a bay.
