John Lewis, a sub-librarian in a small Welsh town, finds his professional ambitions and personal life colliding when he begins an affair with a prominent local socialite. Caught between the desire for career advancement and the chaotic consequences of his infidelity, John navigates a series of increasingly absurd social entanglements. The narrative follows his attempts to maintain his standing in the community while managing the volatile demands of Elizabeth Gruffyd-Williams. The story is presented through a third-person perspective that emphasizes the protagonist's internal confusion and the external pressures of his provincial environment.

Readers frequently highlight the sharp, cynical wit that defines the narrative voice throughout the novel. Discussion often centers on the protagonist's lack of clear moral direction and how this reflects the broader disillusionment of the post-war era. Critics often point to the balance between the book's slapstick humor and its biting social critique of provincial life. Many readers appreciate the author's ability to render the absurdity of small-town politics with precision and clarity. The work is widely regarded as a significant example of mid-century British satire that avoids sentimentality in favor of a more clinical observation of human behavior.
