A shiver ran down Clara's spine as she entered the basement, a place she rarely ventured. Now, it was time to finally sort through the basement’s contents.

She began sifting through boxes of her grandfather’s possessions. He had always been a man of few words, a steadfast presence in her life. She was prepared for the familiar. She wasn’t prepared for what she found.

Clara picked up a photo of him, young and tanned, standing on a surfboard, a huge grin on his face. Her grandfather, a surfer? It was a life he’d never spoken about. Another photo revealed him in a sharp suit, leaning against a vintage car, radiating charm. She felt a lightness in her chest, a strange mix of surprise and fondness.
