The grandfather clock struck twelve, its deep chime echoing through the silent, empty mansion. A single candle flickered on the mahogany desk, casting long shadows across the room. The body lay crumpled on the Persian rug, a curious stillness around the scene. No sign of forced entry marred the quaint solitude of this winter evening. Detective Cross knelt, noting the sapphire pin clutched tight within the victim's hand.
