The late afternoon sun cast long shadows across the dusty attic, illuminating motes of dancing dust. Liam grinned, pushing a cobweb from his face with a flourish. "Right, Emily, time to solve a mystery! Remember that time we swore we saw a ghost in Grandma's house?" He hopped onto a rickety trunk.

Emily, perched precariously on a stack of forgotten books, frowned. "Liam, we were eight. We saw shadows, a draft, and maybe a particularly convincing spiderweb." She eyed him, a smile beginning to tug at her lips.

He threw his arms wide, a manic gleam in his eyes. "No! It was a translucent woman! She glided across the hallway, and her breath –" He shivered dramatically, exaggerating the chill. " – turned the air to ice!"

“I remember a very warm house, and us huddled in the blankets because we were scared,” she said, chuckling. “I was convinced it was Mrs. Henderson, the neighbor, sneaking in to get cookies.”
