Book excerpt: Untouchable Fictions considers the crisis of literary realism--progressive, rural, regionalist, experimental--in order to derive a literary genealogy for the recent explosion of Dalit ("untouchable caste") fiction. Drawing on a wide array of writings from Premchand and Renu in Hindi to Mulk Raj Anand and V. S. Naipaul in English, Gajarawala illuminates the dark side of realist complicity: a hidden aesthetics and politics of caste. How does caste color the novel? What are its formal tendencies? What generic constraints does it produce?
