Ark Sool
A new character introduced in the fourth book of Irish author Eoin Colfer's Artemis Fowl series of children books, Commander Ark Sool is the highest-ranking officer in Internal Affairs. An unusually tall and thin gnome, he is a strict and stubborn adherer to regulations. His no-nonsense attitude often pits him against the centaur Foaly, the fairies chief technical advisor, and inadvertantly causes him to assume that Captain Holly Short was the only possible murderer of Commander Julius Root. Throughout the book, he narrow-mindedly pursues Short without considering other possible suspects. In reality, Short was innocent; she had been set up by the pixie genius and megalomaniac Opal Koboi as part of her plans for revenge. Even after Short is cleared of the crime, Sool intends to keep a close eye on her to catch any infractions. His recent promotion to LEP Reconnaisance Commander compels Captain Short to leave the force so she can serve the People without having to watch her every action.
Due to his high position, Sool is expected to make another appearance in future installments of the series.
