Mr. Isog is Arnie Wald's main henchman, specialising in occult capers and contacts.
Mr. Isog is a regular human being, perhaps a bit on the short side. He has knowledge of and contacts in the occult spheres, hence his ploy of "ghost indians" and the hiring of The Black Flame. Mr. Isog is a calculating, cunning tactician who couches his risks in order to prosper. Nevertheless a near fatal flaw of his is that he likes to observe the playing out of his ploys closely. His acting skills allowed him to turn a capture by Cindy Tynan to his advantage before escaping.
