Rain hammered the cobblestone streets. Midnight fog swallowed the lanterns. A scream shattered the silence. The manor's doors creaked open. Detective Hart entered, eyes narrowed. He smelled iron, fear lingering. The body lay beneath chandelier. Blood spattered the marble floor. Whispers hinted at hidden motives. Clock struck twelve, tension rose.
