An elderly millionairesse, Claire Zachanassian, returns to Guellen, her home town, after an absence of many years. Merely on the promise of her millions, she shortly turns what has been a depressed area into a boom town. But there is a condition attached to her largess, which the natives of Guellen realize only after they have become enmeshed in her vengeful plot: murder. Out of these elements, Durrenmatt has fashioned a many-leveled play which is at once a macabre parable, a deeply moving tragedy, and a scathing indictment of the power of greed.
