Pola was seven years old and loved spending time in her colourful room in the attic. One rainy afternoon, she decided to clean under her bed. As she moved a box of blocks, her fingers came across something cold and smooth. It was a tiny golden doorknob! Pola curiously grabbed the handle. Suddenly, she saw the outline of a small door in the wall under the bed. They were painted with dots and looked as if they were waiting just for her. She quickly called her teddy bear, Felk, and together they knelt by the secret door. - I wonder where they lead? - whispered Pola. The door opened with a quiet creak. Behind them was something very bright. Pola felt a slight breeze of warm wind and heard laughter.... someone's laughter? Or was it the wind playing like that? - Maybe there is someone living there who likes to hide? - wondered Pola. She carefully slipped her head through the tiny door and saw.... But what Pola saw, no one knows yet. What could be on the other side of the mysterious door?
