The water in the pool sparkled, reflecting the cerulean sky. Emily splashed in the shallow end, the cool water a welcome relief from the summer heat. Laughter bubbled up from her throat as she chased after her children. They’d just finished a delicious lunch of sandwiches and watermelon. The house felt warm and welcoming, filled with the sounds of their carefree day. Later, she planned to get started on her book.

A woman approached, a notepad clutched in her hand, the sun glinting off the gold chain around her neck. "Excuse me," she said, her voice polite but firm. "I'm from the city archives. I have some records pertaining to this address." Emily, dripping wet, waved her hand in invitation towards the patio furniture. "Oh really? Come on out of the sun, I was just about to make some lemonade."
