The scent of old paper and forgotten secrets filled the small, cramped study. Elara rubbed her hands together, a shiver of anticipatory delight running up her spine. She'd been tasked with cataloging her great-aunt Millie's belongings, and it was turning into an unexpected adventure.

A small, velvet-covered album felt heavy in her hands. The first image showed a young Millie, usually depicted as a pious church-goer, in a red dress, laughing gleefully while dancing with a group of friends. Elara's smile grew wider.

Flipping through the album, she uncovered a series of candid shots. Millie, supposedly a woman of refined tastes, was scaling a tree, covered in mud, and eating a stolen apple. Elara's heart swelled with a giddy feeling. This was far more captivating than she'd anticipated.
