The freshly polished floors gleamed in the sunlight as Alice danced around the living room, singing off-key. The boxes were unpacked, the furniture arranged to her exact liking. She was giddy with contentment. A new life, a new beginning; she could hardly contain her enthusiasm. It didn't matter what the house had seen before. She would fill it with joy.

A man arrived at the door in a suit. He introduced himself, and started to tell her about the unfortunate events that occurred in her new home. Alice clapped her hands together, a look of pure excitement on her face.

"Fascinating!" she exclaimed. "What a story! Is there a movie adaptation? Ooh, I wonder who would play the killer!"
