Under the pale moonlight the detective entered the room and found the body lying motionless on the expensive wooden floor. Blood stains marred his expensive suit as a strange threatening message was written on the wall in bright red ink. The detective carefully examined the lifeless corpse while wondering exactly who could possibly have committed this heinous act of violence.
