The clock struck midnight in silence. A scream shattered the quiet night. Blood pooled on the marble floor. The body lay cold and still. A single lamp flickered dimly. Detective Voss arrived at the scene. Her sharp eyes scanned every detail. A broken vase lay shattered nearby. A single footprint marked the carpet. Nothing else seemed out of place. The victim's hand clutched a note. It read: “You should have listened.”
