The 39 Clues Website is where users can sign up collect cards and clues, play missions, read articles about the characters, play games, and learn top-secret information. An alternate URL to the site is: www.NessieLives.com, which is only located in the inside flap pages of The Maze of Bones. This is a connection to the mission which comes with the book, Mission 1: The Lost Clue, in which you investigate the Loch Ness monster, known as Nessie, for a Clue.
