In "The Assassination of Margaret Thatcher," Hilary Mantel explores themes of fear and cultural identity through the narrator's encounter with a remarkably pure and idealistic person. The narrator perceives this individual as almost too good to be true, prompting a sense of wariness and suspicion. The description emphasizes the character's seemingly flawless nature, which evokes anxiety about potential manipulation or conversion.
This encounter reflects broader worries about the influence of idealism and foreign ideologies. The narrator's instinct to distance themselves underscores a hesitancy towards those who appear excessively virtuous, particularly when it might challenge their own beliefs or way of life. Mantel captures the tension between admiration and suspicion in human connections, illustrating how such dynamics can provoke both attraction and fear.
