Abstract
This article examines the concept of 'self-possession' as crafted by Henry James in his representation of Madame Serena Merle in The Portrait of a Lady (1881) and traces how John Banville adapts this characterisation in his 2017 sequel Mrs Osmond. Madame Merle’s self-possession, a carefully crafted public persona that conceals private agency, represents both her survival strategy as a nineteenth-century woman who has transgressed social boundaries and her capacity to function as a kind of author who propels the novel’s central action. Through close textual analysis, this article argues that Madame Merle’s self-possession operates as a dual phenomenon: an outward performance of composed refinement 'for other people' and an inner retention of guarded autonomy. The article then explores how Banville appropriates this template of female self-possession to enliven his iteration of Isabel in Mrs Osmond. This analysis reveals that Banville’s only female protagonist emerges through his adaptation of James’ portrait of female self-possession, suggesting that the template established by Madame Merle remains essential to imagining female autonomy within patriarchal constraints.
