-- The Horned Hood src

Professor Cadiz was an expert on historical gems, at a museum somewhere upstate from Gotham City. He got greedy, adopted a secret identity as the Horned Hood, recruited a small gang, and stole the famous Maharajah Jewel from his own museum. Not much later, he and his gang were tracked down, beaten senseless, and left for the police, by the noted vigilante Mister Scarlet.
