Rain hammered the cobblestone alley. Fog curled around flickering streetlamps. Detective Mara entered, breath shallow. She found a crimson envelope. The victim's name was Whitaker. Neighbors whispered about midnight arguments. A single glass shattered nearby. Footprints led toward the pier. Moonlight revealed a bloodstained coat. Silence hung heavy over water. Someone watched from shadowed arches. The clock struck twelve, ominous.
