The heavy rain fell hard against the wooden doors of the old mansion where they found the body lying there. The weary detective stepped forward, noticing a crimson puddle spreading across the polished hardwood floorboards near the cold stone wall. A tarnished silver pocket watch rested broken on the thick woven rug beside the motionless victim waiting in the shadows. An intruder had moved through this room long before the arriving authorities came to secure the quiet premises properly today. The mystery deepened quickly now, as every clue pointed somewhere away from what they expected to find inside this place.
