The squeak of the swing set in the backyard, newly installed, filled the late afternoon air. Little Leo, her son, giggled as he pumped his legs higher and higher. Lily, watching him, felt a light, airy feeling in her chest. She'd always wanted a house with a big backyard for her son. The realtor had mentioned some "historical intrigue," but she hadn't worried about it. She was too preoccupied with making the house a home.

Suddenly, a woman with a nametag on her uniform showed up. The woman explained the history of the house, which sounded like a movie plot to Lily. She was nearly bouncing on the balls of her feet as she listened.

"Wow!" Lily exclaimed. "Imagine! The suspense!" She could not help but be entertained by the story she was hearing, forgetting all about her son's swing set.
