The thesis employs theory alongside textual evidence to demonstrate how Go Set a Watchman impacts a nostalgic reading of To Kill a Mockigbird. This was accomplished by studying the characterization of Atticus Finch as he appears in the two novels through intertextuality. Similarities and differences have been found in comparison to prior research. The study finds that the nostalgic image of Atticus Finch is shattered in Go Set a Watchman, thereby negatively impacting a nostalgic read of To Kill a Watchman.
