Here is a 146-word opening scene for a murder mystery with sentences of exactly 10 words each: The night was still. A full moon lit the quiet street. A dog barked in the distance. Shadows crept along the sidewalks. Suddenly, a scream pierced the calm. It echoed through the neighborhood. Lights flicked on in dark houses. Doors opened cautiously. Nervous eyes peered outside. No one saw anything unusual. Police sirens wailed as cars raced to the scene. Neighbors whispered fearfully on front porches. Detectives searched for clues in the darkness. Their flashlights danced under trees. Radios crackled with terse reports. And somewhere, a killer slipped unseen into the night.
