The heavy rain poured down on the old mansion as Detective Harris arrived at the mysterious crime scene late tonight. Inside the dimly lit hallway a lifeless body lay sprawled across the expensive Persian rug with a bloody knife nearby. The detective knelt beside the body to examine the victim who seemed like a rich man around fifty years old. No signs of a struggle were visible anywhere in the luxurious room indicating the murderer knew the victim quite intimately. A note was found clutched in the dead man's hand with a cryptic message that hinted at a dark secret.
