This thesis argues that Robert Louis Stevenson's South Seas writings locate him alongside Joseph Conrad on the 'strategic fault line' described by the Marxist critic Fredric Jameson that delineates the interstitial area between nineteenth-century adventure fiction and early Modernism. Stevenson, like Conrad, mounts an attack on the assumptions of the grand narrative of imperialism and, in texts such as 'The Beach of Falesa' and The Ebb Tide, offers late-Victorian readers a critical view of the workings of Empire. The present study seeks to analyse the common interests of two important writers as they adopt innovative literary methodologies within, and in response to, the context of changing perceptions of the effects of European influence upon the colonial subject.
