Everyone said that the library in Pines Street had been locked up for years and that not even the light looked in there after dark. But of course, it was there, in the gloomy silence, that a group of four friends decided to enter on the last evening of August. Lena, Nikolai, Sara and Igor were not superstitious people, rather they were looking for something to cut through the boredom of the beginning of the school year. The building, with windows overgrown with ivy like a cobweb of time, had attracted them for a long time. They entered through a broken door at the back, stifling laughter at their own boldness. The darkness inside was almost palpable, but Lena, who always had a torch in her backpack, illuminated the long rows of bookcases with the beam. The library looked as if someone had left it suddenly - there were open books on the shelves, old glasses, a mug of tea covered by a thick layer of dust. - Hey, can you hear? - whispered Sara, stopping by the librarian's massive oak desk. - Something's buzzing... - It's just the wind - muttered Igor, trying to sound brave. But then they all clearly heard a quiet voice, as if someone was speaking in a slightly hoarse whisper: - Wind? It's a rather forlorn word... The friends froze. They looked at each other, then at the desk. The old clock stood still, the hands stopped at 5:13 p.m. A fine mist was rising from the cup, though after all, the tea must have been cold for years. Lena knelt down and looked under the desk. Nothing. After a moment, she touched the old pen lying next to the notepad. The pen twitched. - Who are you? - asked the pen quietly, fluttering the nib from side to side. Sara took a step back. - Did you hear that! - hissed Nikolai. At the same moment, the rasp of wood sounded. One of the bookcases, standing in the corner of the room, began to move. Books trembled on the shelves, and two tiny lights flashed from the darkness between the volumes. The library door slammed behind the teenagers' backs with a bang. The whisper of the pen fell silent: - If you have come for answers, you must first ask the right question.... And then the bookcase moved away completely, revealing a hidden passage from which a greenish glow began to seep. Suddenly, all the objects in the library - the forgotten glasses, the cup and even the old books - began to speak at once....
