Herman Preminger

Herman Preminger is the disowned son of Duke Preminger. He is the brother of Colette Preminger and the uncle of Nadja.

He married the widow Hilda, who is the mother of Oscar Colrad from her previous marriage.

He co-opts Rosso and Bianco to work for him rather than the Duke, in an effort to eliminate Nadja so she can not be an heir.

He later meets Rosemary and they plot to replace Nadja.
