Thurzó enlists Erzsébet's sons-in-law and other allies to prosecute her for witchcraft. When their plans repeatedly fail, they nonetheless capture the Countess and torture members of her household to try to obtain incriminating information. The servants are then executed for their alleged crimes, and Erzsébet is imprisoned. Despairing over her separation from her son, she lies on her bed and begins to sing a hymn; the flames from her candles rise and engulf her in flames. Upon hearing of her death, Thurzo concedes that she has once again made the move he least expected, as when they once played chess together, and admits that he has always loved her.
