Unfortunately, they made a great deal of enemies from this moment on, not understanding mafia laws, and ended up losing a lot of their wealth in doing so, which eventually led them to join SCORPIA until the point of its collapse. Desperately in need of money in order to sustain their luxurious lifestyle, the twins hatch a scheme named Operation Steel Claw, involving the hijacking of an extremely large and expensive helicopter from the United States Air Force with a metal claw attached, with which they pick up a school bus filled with children from wealthy families in order to hold them to ransom. Alex Rider becomes involved in their affairs after receiving an email from Jack Starbright, claiming that she's still alive, and Alex encounters the Grimaldi twins during his search for her. After failing to kill Alex with cement shoes, the twins take the children to an abandoned factory complex in Wales, along with Jack, whom they had saved from Abdul-Aziz Al-Razim in order to use her to keep the children under control. Alex manages to avoid the Grimaldi twins' henchmen and reunite with Jack, and the two of them succeed in rescuing the children by driving the school bus along a disused railway track. However, the Grimaldi twins soon give chase in a steam locomotive and desperately attempt to kill Alex with machine-guns, but Alex fills a drinks flask with leaking fuel from the bus before throwing it into the funnel of the locomotive. Seconds later, the train explodes and kills the Grimaldi twins instantly. Giovanni was born first, with Eduardo following five seconds later. Similarly, when Alex caused their train to explode, Giovanni died first, with Eduardo following five seconds later. In terms of appearances, the twins are identical in every respect, wearing the same clothes, eating the same food at the same time, sleeping at the same time for the same time, and owning the same cars and the same guns. The only way they can be told apart is that they have different dominant hands: Giovanni is left-handed, whilst Eduardo is right-handed, which can add to the illusion that they are mirror images of one another, as shown in their first scene in "Never Say Die" where they eat breakfast by the swimming pool at their villa, sitting opposite one another, appearing like one man and his reflection. Both are described as being very "neat and delicate, almost like schoolboys, with very round heads and black hair that could have been painted on, coming down in cowlicks over their foreheads", but very unattractive, with dark "always suspicious" eyes, very small mouths and permanent dark stubble across their faces, "like sandpaper", giving them an almost devilish appearance.
