The stability of a provincial English community is shattered when a horrific crime against a child forces the protagonist to confront the fragility of human morality. Lewis Eliot, the narrator and observer, finds himself drawn into the legal and social fallout of a brutal murder case involving two young defendants. As he navigates the complex interplay between the legal system, public outcry, and the personal lives of those involved, he must reconcile his own rationalist worldview with the irrational violence that has surfaced in his society. The narrative framework remains grounded in Eliot's reflective, first-person perspective, providing a measured account of the moral dilemmas faced by the characters as they grapple with the implications of the crime.
