The Artemis Fowl Files
Eoin Colfer
 Artemis Fowl lures Mulch Diggums, a dwarf, to work with him to steal a tiara for a laser he is developing. A band of other dwarfs, using a circus as their cover have already stolen the tiara. The other dwarfs, led by Sergei the Significant, are planning to sell it to a jewellery fence. Captain Holly Short is on a break pending a tribunal after the Fowl Manor Incident, but Foaly tells her that the LEP have been alerted by Mulch Diggum's stolen helmet, about Artemis Fowl. Holly immediately heads to Ireland and confronts the dwarfs. Soon after Holly has tagged all of the dwarfs in Sergei's band, she chases Artemis and Mulch. Mulch and Artemis soon split with Artemis promising to write Mulch a cheque for the tiara. Holly chases after Artemis and demands the tiara and a LEP helmet from him. Artemis gives her the LEP helmet but keeps the tiara. Holly forces Artemis to give her the tiara, and then he hands it over. Later on we learn that Artemis switched the gemstone in the tiara with a fake one. He gives the real one to his mother because it reminds her of Artemis's father, specifically, the color of his eyes.
