Artemis Fowl: The Seventh Dwarf

Artemis Fowl lures the dwarf, Mulch Diggums, to New York City and then brings him back to Ireland to steal the priceless Fei Fei tiara which contains a one-of-a-kind blue diamond. Artemis claims that he intends to use it for a laser. However, a gang of six dwarves led by Sergei the Significant have already stolen the tiara and plan to sell it at a circus to several European jewellery fences. As the dwarfs perform in the circus, Mulch sneaks in underground and takes the tiara, also knocking out their leader, Sergei.

LEP Captain Holly Short has been relaxing in a luxury resort belonging to the People while waiting for the Council to clear her name after the incident at Fowl Manor. However, Foaly calls her saying that she must track Artemis's plane; the LEP have been alerted by Mulch's stolen LEP helmet. Holly Short catches Artemis with the tiara, but not before he manages to swap the priceless blue diamond for a fake. Holly takes the fake tiara and wants to wipe Artemis’s memory of the people. However Artemis points out that he merely committed a human crime and did nothing to expose them. Thankfully Holly does not know of Mulch’s involvement so this is accepted. Ultimately, it is discovered that Artemis stole the diamond as the colour reminded him of his father's eyes. He gives the diamond to his mother as a gift and promises her that he will find his father.
