A self-righteous idealist insists on telling a family the truth about their past and destroys them. Ibsen wrote it as a corrective to his own reputation: after A Doll's House made him the champion of truth-telling, he wrote a play arguing that some people need their illusions to survive. It's his most ambiguous work, and maybe his best.

The case for it, the case against, and the rest of the canon open with Pro.
