The body was discovered at precisely seven forty-five that morning. Detective Sarah Chen arrived at the sprawling Victorian estate quickly. Rain had been falling steadily throughout the cold November night. The victim lay sprawled across the marble foyer floor dramatically. Blood pooled beneath his head in a dark crimson circle. His name was Jonathan Blackwood, a wealthy prominent local businessman. The butler had found him while preparing morning tea service. No weapon could be located anywhere near the crime scene. All house guests claimed they had slept through the night. But someone among them was lying about their whereabouts surely.
