ARTIMIS FOWL THE ETERNITY CODE

I just finished the second book (Artimis fowl the arctic incident) and now I am on the third book Artimis fowl the eternety code. It is about a kid named Artimis fowl a 13 year old kid who is incredibly smart. In this story he attempts to sell a very expensive item called the c cube to a man named Jhon spiro. Jhon spiro meets artimus at a resturant then ambushes them badly wounding Artimis's butler, Butler.
