His shop, a quaint corner of tranquility amidst the urban chaos, was filled with the gentle ticking of countless timepieces. Each clock was a masterpiece, a testament to his dedication and skill. But Alistair held a secret. One of his clocks, an old grandfather clock in the corner, did not just tell time. It told stories. | |
| Every midnight, as the city slept, the clock would chime, not with bells, but with whispers of forgotten tales. Stories of ancient kings, lost love, and adventures in lands woven from starlight and dreams. Alistair would sit by the fire, listening, his heart filled with the magic of the past. He was the keeper of time, and in turn, time had made him its confidant. | |
| One day, a young girl with eyes as curious as a cat's wandered into his shop. She wasn't interested in the shiny new watches but was drawn to the grandfather clock. "What's its story?" she asked, her voice soft. Alistair smiled, for he knew he had found the next guardian of the stories. The legacy of the whispering clock would live on.""" | |
