[1] Fowl meets Chicago businessman Jon Spiro in London to show him the Cube, in an attempt to buy a considerable amount of gold in exchange for keeping the technology off the market.

Artemis' demonstration of the Cube inadvertently detects Fairy technology below ground, causing a shutdown of all equipment in Haven city.

In response, Commander Root sends Captain Holly Short to London to find what the disturbance was caused by.

Root demands a mind-wipe of the three humans after the job is done, so Artemis leaves Butler in Ireland to ensure their memories survive.

The heist is ultimately successful, with Artemis retrieving the Cube after tricking Spiro into entering a rival company's headquarters to steal their new products.

The Chicago police immediately arrive to arrest Spiro and his associates, and Foaly wipes Artemis' movements from the CCTV.

Although Arno Blunt escapes and tries to enter Ireland to kill Artemis, Butler has him detained and frightens him into confessing his crimes.
