This chapter discusses the two geographical environments that predominantly shape Iris Murdoch’s identity and her fiction: Ireland, her birthplace, the ‘island of spells’, and London, the city in which she spent much of her life and spoke of as ‘sacred’. It first explores Murdoch’s often tortuous relationship with her homeland and the political upheavals that engulfed it during her lifetime, then moves on to illustrate how this ambivalence is reflected in a number of her Irish characters and the metaphorical fogs and mists that characterise her two ‘Irish’ novels The Unicorn and The Red and The Green. The second half of this chapter celebrates her less equivocal love of London, the dominant setting in twenty-four of the twenty-six novels, which is celebrated with an extraordinary acuity of detail. The chapter concludes with discussions of the ways in which the London settings serve multiple symbolic functions that include a sophisticated awareness of the complex connections between psychological well-being and the environment, distinctly feminist explorations of the male psyche, and an encoded system of images that points toward the moral issues within the novels.
