In "Search for Justice" level, Find a "Hativania" sign in front of a tall, gray building. Go west until you find 2 thugs beating up a red-haired woman. Once you defeat the thugs, the woman says she lost her purse. Go back to the rooftop with the "Hativania" sign &, on that roof, you will find a darkish yellow purse. Go back to the woman & at the end of the level, you will get 500 points for the "secrets found" bonus.
