The morning sun barely peeked over the eastern horizon when Detective Sarah Chen arrived at the old Victorian mansion yesterday. She stood motionless near the front gates, staring up at the dark windows where death had claimed yet another victim. Bloodstains still marked the white marble steps leading to the grand entrance where the lifeless body had finally been discovered. A single yellow police tape fluttered gently in the morning breeze, warning everyone to stay back from this terrible scene. Inside the dusty library, three strangers waited nervously for answers about the wealthy man who died so mysteriously last night.
