Here is a 5-word-per-sentence opening for a murder mystery story: She entered the dark house. A floorboard creaked under her feet. Shadows danced across the walls. The air was heavy and still. A putrid smell filled her nose. She walked slowly down the hall. A light flickered under a door. Reaching out, she turned the knob. The door opened with a long creak. There lay the body, lifeless. Blood pooled around the victim. Her scream pierced the silence.
