In ‘Darkly Dreaming (in) Authenticity: The Self/Persona Opposition in Dexter,’ Glenn D'Cruz uses Dexter Morgan, the novelised serial killer and Showtime TV anti-hero to examine the connections between self and persona and the discourse of authenticity. D’Cruz foresees a series of challenges for persona studies and considers key concerns ahead, in terms of the critical vocabulary and scholarly agenda and addresses the need for critical genealogy of the term ‘persona’.
