Setter, an eminent Harley Street consultant, is trusted and admired by his circle of friends, devoting himself to the rehabilitation of the lonely and the misunderstood. But deep within himself Setter recognizes a latent streak of sadistic cruelty which enables him to perceive the truth about a delinquent youth whom he suspects of having taken part in a particularly repellent and senseless crime. It is for Setter to choose a punishment--and enforce it. "An Error of Judgement" is a subtle study of human weakness and conflict. Partly a wry social comedy and partly a study in good and evil, it is brilliantly written and observed, assured and skillful, and a truly modern work.
