Detective Mickey Harrigan

Harrigan is the humane, yet efficient, representative of the Arkham police. Where Lt.Luther Harden walks over dead bodies, to achieve his objectives, Harrigan wins the day by scrutinizing the evidence one more time. It is not unheard of that Harrigan( and not Harden) is the one finding the final crucial evidence that will send a criminal to the slammer. When Chief Nichols leaves his office one can expect that Harrigan will be the obvious choice for new chief. The question is how Harden will take this.
