In "Artemis Fowl", which is set two years after those events, the 12-year-old Artemis decides to regain the Fowl fortune by following leads on the Internet that refer to an underground world of fairies collectively called the People. Artemis manages to blackmail a member of the People into giving him what they call "the Book" which is like their Bible, holding all their secrets, customs, rules, and history. This leads him to ransom Lower Elements Police (LEP) Captain Holly Short for a portion of the People's gold. Artemis and Holly agree to a deal whereby Holly retains half the ransom fee, while Artemis gets one wish from Holly and gets to keep the other half of the gold. After recovering Holly, the LEP attempt to permanently eliminate Artemis by setting off a biological weapon, but are thwarted when Artemis discovers a way around their attack (something not even the People had been able to develop).
