Fog draped the harbor tonight. Whispers curled along rainsoaked walls. A body rested beneath lamplight. The clock sighed, counting hours. Street doors clattered in wind. A detective arrived with rain. Notes waited inside the notebook. Evidence teased the midnight silence. Whispers hinted murder within shadows. Red ink stained the note. Morning would reveal the truth.
