The body lay sprawled across the velvet sofa in silence. Detective Miller stared at the crimson stains on white carpet. She noticed the silver letter opener near his cold hand. The grandfather clock chimed twelve times in the dark room. Rain lashed against the tall windows of the mansion outside. A single rose petal rested on the cold victim's chest. Nobody else had entered this sealed room since midnight yesterday. The detective photographed every small detail before touching anything else.
