The most famous "specialist" associated with Captain Pantoja, Olga Rosaura is known as The Brazilian because of time spent in that South American country. The only daughter of Hermes Rosaura, Olga spends a troubled childhood and adolescence in the Iquitos/Loreto area before running away and making a name for herself as a famously irresistible prostitute. It is said that more than one unsuspecting man has met his death for love of the Brazilian. Eventually, she and Captain Pantoja become lovers, causing Pantoja's wife to leave him. After she is murdered in a foiled plot to kidnap her, Pantoja delivers an emotional eulogy at the woman's funeral which hastens the collapse of Pantoja's military career and the entire Special Service project. The Brazilian's life is chronicled in a newspaper account in Chapter 9.
