The Trial and The Castle have been chiefly responsible for the posthumous fame and popularity of Franz Kafka. The Trial, the story of Joseph K.—the respectable functionary in a bank who is suddenly arrested, and who then must spend the rest of his life fighting a charge against him of whose nature he can get no information--has achieved the symbolic status of a modern myth. It is now available in a volume containing more than 10,000 words not included in the first American edition.  The earliest German edition of Der Prozess—from which Willa and Edwin Muir made the first English translation of The Trial—did not contain all of the text that Kafka had left in manuscript. In the definitive German edition of Der Prozess, Max Brod (1884-1968)--Kafka's closest friend and literary executor—restored many passages omitted from the earlier edition. The present English edition contains that restored material.  The new material is of two kinds: uncompleted chapters and passages struck through by Kafka. The Postscript by Brod contained in the first English edition has also been expanded; two new brief postscripts have been added. The translation of the new materials has been made by Professor E. M. Butler, who has also slightly revised the previously existing English text in the direction of making it conform more closely to Kafka's original.
