The silence of the old house on the edge of town was almost palpable. Lena stretched and looked out of the study window, which overlooked the overgrown garden. - 'David, are you sure your great-grandfather had something so unusual here? - She asked doubtfully. - 'My grandmother said there are things in the attic that nobody has touched to this day,' replied David, looking excitedly at the entrance to the upstairs. He was 14 years old and couldn't sit still whenever he sensed a chance for adventure. The attic was exactly as they had imagined: stuffy, full of cobwebs and abandoned objects. They moved carefully so that the boards didn't creak too loudly. Light drifted lazily through the tiny window, illuminating the shelves bent under the weight of old books and boxes bound with thick string. In the corner, behind a broken suitcase, stood an old clock with a pendulum. It was huge, with a carved case on which they noticed faded symbols. Lena ran her hand over its surface, feeling the coolness of the wood under her fingers. - Look! - she called out. - It has two dials! One shows the time, but the other...

They felt soft moss underfoot, and above their heads stretched a sky of a completely different shade to the one they knew. The trees had silvery leaves, and in the distance they could hear the clatter, as if of wooden wheels on stone streets. - Where are we? - whispered Lena, trying to get her trembling voice under control. David looked behind him and saw that the clock lay overturned among the ferns, but the hands - still moving. Suddenly, voices came from behind the trees, sounding familiar but speaking in words they had never heard before. They both froze in stillness, listening for footsteps approaching towards them....
