Rupert of Hentzau: From The Memoirs of Fritz Von Tarlenheim / Sequel to The Prisoner of Zenda 

This is a sequel to the famous 'Prisoner of Zenda, ’ already published in the Nelson Library. It tells of the end of the long vendetta between young Rupert of Hentzau and the Englishman, Rudolph Rassendyll. It is needless to praise a book which, with its predecessor, has been recognized as one of the greatest of modern romances.
