The body lay sprawled on the marble floor, silent now. Detective Miller knelt beside the victim, studying the bloody wound. Rain tapped against the windows, muffling the city's usual noise. A single red rose rested near the deceased's outstretched hand. Three suspects waited nervously in the hallway beyond the door. She had been beautiful once, before death stole her breath.
