Distended Youth: Arrested Development in the Victorian Novel examines the figure of the eternal child, the childlike adult and other aberrant permutations of the figure who has neither fully exited childhood nor entered adulthood, and the ways in which such figures are made Gothic as an expression of a peculiarly Victorian anxiety surrounding the oft elided or adumbrated transition from innocent and generative childhood to corrupt and destructive adult. It uses Dickens's Bleak House, Brontë's Villette, Eliot's Scenes of Clerical Life and Barrie's Peter and Wendy as texts where childhood goes awry, and is either unnaturally extended, or else returned to after a period as an adult. In tracking an increasingly paranoid literary desire to protect and preserve childhood, both real and in fiction, the dissertation seeks to show the genesis and evolution of this Gothic intervention, and prove that such tracts, rather than being odd detours in the novel, are powerful expressions of social instability at the heart of a staple of Victorian culture.
