A mysterious stranger arrives in the remote village of Viscos, initiating a high-stakes moral experiment that forces the inhabitants to confront the duality of their own natures. The stranger, burdened by a dark past and carrying eleven gold bars, seeks to determine if humanity is inherently good or evil by offering the villagers a life-changing sum of money in exchange for a single act of murder. Miss Prym, a young woman struggling with her own aspirations and the stagnation of village life, becomes the stranger's primary interlocutor and unwilling accomplice. The narrative unfolds as a tense psychological study, examining how greed, fear, and the pressure of collective decision-making can dismantle the ethical foundations of a community.

This work is frequently analyzed for its continuation of the author's interest in spiritual and moral inquiry, often drawing comparisons to his earlier, more fable-oriented narratives. The premise suggests a deliberate, slow-burning examination of human ethics that prioritizes thematic depth over complex plot mechanics. Readers often note the stark, almost clinical way the author presents the villagers' descent into moral ambiguity, which serves to highlight the fragility of social order. The narrative structure functions as a mirror for the reader, inviting them to participate in the same ethical calculation as the characters within the village of Viscos.
