Chief Detective Luther Harden
Luther Harden is the archetypical tough detective. He is a loner with a hard-boiled attitude. If something bad happens in Arkham you can expect that he will be there. He is the best investigator that the Arkham police can send forth. If a criminal gets involved in crime, that will be investigated by Harden, he/she can expect that things will turn sour quite soon. Harden is known to go beyond the set limits of his office. This is both his main advantage as well as main weakness. Some day he may get fired for beating up a bad egg too many.
