Plot outline

During the first book in the trilogy, which is called simply Artemis Fowl, Butler disarmed a LEPRetrieval squad. Using the technology from their helmets, Artemis has built a tiny computer - the C Cube, the "cube that sees everything". He plans to show the C Cube to Jon Spiro. During their meeting, Spiro outwits Artemis by hiding assassins in the restaurant where they are having lunch. Butler sets off a fairy sound grenade, knocking the assasins unconsciouss, but Arno Blunt is unaffected by the greande, having put in ear plugs, and attacks Artemis. Butler takes the bullet and a long and heartwrenching death scene follows, during which Butler reveals his first name _ Domovoi. However, Artemis isn't prepared to just let him go _ he freezes Butler cryogenically until Holly arrives to heal him.

Then things get really crazy. The healing goes wrong and Butler is left mutilated, with Kevlar fibres embedded in his chest _ and he's fifteen years older. Now fifty_five, he is unable to fulfil his capacity as a bodyguard. His little sister, Juliet Butler takes over as humans and fairies mount a huge operation to get the C Cube away from Spiro before he uses it against the fairies, culminating in a dramatic, second-by-second engineered infiltration of Spiro's office block, the Spiro Needle, by Juliet, Holly and Mulch Diggums.
