What is evil? Is it a disembodied force, or an aspect of being human, or both? How do we locate it within the contemporary world? What does it look like? Can any metaphor adequately describe it? It has been said that no author of the twentieth century was more aware of the many forms evil takes than the Catholic Muriel Spark, who used satire and ridicule to great effect when portraying human evil, physical and metaphysical. This essay gives an overview of Spark’s expositions of evil in three brilliant, short, and immensely funny novels from her prime: “The Hothouse by the East River”, “The Abbess of Crewe”, and “The Takeover” (6,500 words).
