L. Frank Baum 
The Fate of a Crown 

‚The Fate of a Crown‘ by L. Frank Baum follows a young American named Robert Harcliffe; a recent college graduate, he works for his family’s mercantile business in New Orleans, run by his Uncle Nelson. Nelson Harcliffe receives a letter from an old client in Brazil, Dom Miguel de Pintra, a wealthy man who has retired from business to devote himself to politics – specifically to the republican cause that struggles to replace the Brazilian Empire. Dom Miguel has written to request a secretary; Robert, eager for adventure, agrees to take the job.
