Rigoletto, holding the ladder below, still imagined that it was his enemy's house that was being entered; and when the ravishers presently returned, bearing Gilda in their arms, he rejoiced, thinking that the victim was Ceprano's wife. His hearing being dulled by the tight bandages over his ears, he did not catch the stifled cries of the poor girl as she was quickly borne away; and it was not until the maskers were far out of his reach that he discovered he had been left alone.

Then, tearing off his bandage with difficulty, he saw that the ladder was leaning against the wall of his own house; and realising the cruel trick that had been played upon him, he was filled with rage and despair. He rushed madly down the street towards the palace, trembling for the fate of his beloved child; and forcing his way to the ante-room adjoining the Duke's private chamber, he found his enemies already there. For the plotters had immediately brought their prize in triumph to their royal master, declaring her to be the mistress of Rigoletto; and the Duke had received her with joy, on recognising the lovely features of his own new lady-love.

When Rigoletto reached the ante-room, he passionately demanded to have his precious daughter restored to him, being filled with woe on learning that she was even now in the power of the Duke; but the courtiers, though astonished to know that she was his child, only met him with derisive laughter, utterly disregarding his frantic appeals for mercy.

But at that moment, Gilda herself rushed forth from the Duke's room, and flung herself in her father's arms, having heard his voice in the ante-room; and as the Jester quickly hurried her away, she poured forth into his ears the whole story of her infatuation for the handsome cavalier who had admired her in church, of his visit to her that evening, and of her despair on now discovering him to be but a base libertine, who only desired to use her as his plaything.

Yet, even in spite of this knowledge, the poor girl loved him still; and when Rigoletto swore vengeance on the false betrayer, she entreated him to spare her lover, whom she had already forgiven for the wrong he had done her.

But Rigoletto's anger against his royal master was so furious that nothing but death would satisfy his longing for revenge; and quickly sending for Sparafucile, the bravo, he bargained with him for a sum of gold to entice the Duke to his lonely inn and murder him there. A few days later Sparafucile returned, saying that his sister, Maddalena, had already brought herself before the Duke's notice, and enticed him into a promise to visit the inn that evening, when his murder would be easily accomplished during the night; and Rigoletto determined to take Gilda to the spot also, that he might convince her of her base lover's faithlessness, and so cure her infatuation for him.

So when dusk fell, the Jester and his daughter quickly made their way to a wild spot on the outskirts of the city; and on arriving at the bravo's lonely inn, Rigoletto drew the maiden into the shadows near a window, from whence they could see and hear all that took place in the room beyond.

A few minutes later, they saw the Duke, in disguise, enter the inn; and as Sparafucile left the room, after serving the guest with wine, his pretty gipsy-sister, Maddalena, took his place. The Duke at once began to make love to the girl, who, however, only laughed and teased him in return; and when Gilda thus saw for herself how soon her fickle gallant had forgotten her, and heard him utter the same sweet love-speeches to the gipsy-girl that he had whispered into her own delighted ears only a few evenings ago, she was filled with deepest grief.

Rigoletto, seeing that his daughter was at last convinced of her lover's faithlessness, was now eager to get her away from the inn, not wishing her to know of the tragic end in store for the false betrayer; and bidding her hasten home at once, he told her to disguise herself in the garments of a youth, which he had provided for her, and to then fly on horseback to Verona, where he would meet her later on. At first, Gilda could not bring herself to leave the spot; but when her father sternly repeated his command, she hurried away at once to obey his will.

Sparafucile now came out to learn his final instructions, and Rigoletto told him that after murdering the Duke, he was to place the dead body in a sack, that it might be ready for him to throw into the river Mincio that flowed close by. He then gave the bravo half of the money agreed upon between them, and promising to return at midnight with the remainder of the money, when he should expect to find the deed accomplished, he departed.
