In the second act the Duchess is seen pleading with her husband that he should feed and assist his starving people. On his exit she is joined by Guido, who, for the first time, declares his love, while she avows hers in turn. A pretty love scene full of tenderness and poetry is interrupted by the appearance of Count Moranzone, whom Beatrice alone catches sight of, and presently a messenger enters and hands Guido a parcel containing the fatal dagger. He will have no more to do with love--for will not his soul be stained with murder?--and steeling his heart against Beatrice he bids her farewell, telling her that there is a barrier between them. The Duke makes a brief entrance. The Duchess will not go hunting with him. He suspects, and inquires for Guido, and with a veiled threat leaves her. She will end her life that very night, she soliloquises, and yet, why should she die, why not the Duke? She is interrupted by Moranzone, whom she taxes with taking Guido from her. He answers that the young man does not love her nor will she ever see him more, and leaves her. She determines that that very night she will lie in Death's arms. The third act takes place at night within the Palace. Guido enters the apartment from without by means of a rope ladder, and is met by Moranzone, to whom he declares that he will not stoop to murder, but will place the dagger, with a paper stating who he is, upon the Duke's bed and then take horse to Venice and enlist against the Infidels. Nothing Moranzone urges can move him and the latter at last leaves him. As Guido lifts the curtain to enter the Duke's chamber he is met by Beatrice, who, after a while, confesses that she has stabbed her husband. Guido, horrified, refuses to have aught to do with her, and despite all her blandishments and entreaties remains adamant. She then begs him to draw his sword on her "and quick make reckoning with Death, who yet licks his lips after this feast." He wrests the dripping knife from her hand, and although she explains that 'twas for love of him she did the deed he bids her begone to her chamberwomen. Finally she turns on him with the threat "Who of us calls down the lightning on his head let him beware the hurt that lurks within the forked levin's flame," she leaves him. Left alone, his heart goes forth to her and he calls her back, but soon her voice is heard without, saying, "This way fled my husband's murderer." Soldiers enter, and Guido is arrested, the bloodstained knife being taken from him.
