The old mansion stood silent under the pale moonlight as heavy rain poured down relentlessly on that fateful stormy night. Inside the grand hall a lifeless body lay sprawled across the expensive Persian rug with a knife protruding from it. Detective Harris arrived promptly at the crime scene and began examining the evidence while the butler looked extremely nervous nearby. The victim was quickly identified as wealthy businessman Richard Cole who had many enemies due to his ruthless business practices. Blood stains covered the wooden floor around the body indicating a violent struggle had occurred just moments before the discovery. All the guests at the fancy dinner party were now suspects in this shocking murder that disrupted the evening completely.
