The reminder, however, is too sharp: Hieronimo becomes temporarily mad, mistaking Bazulto for Horatio and uttering pathetic laments over the change that has passed over his youthful beauty. Sweet boy, how art thou chang'd in death's black shade! Had Proserpine no pity on thy youth, But suffer'd thy fair crimson-colour'd spring With withered winter to be blasted thus? Horatio, thou art older than thy father. When the fit passes, he and Bazulto go off together, one in their misery. But the guileful scheme is not forgotten. Some one has observed the strained relations between the Marshal and Lorenzo: Lorenzo's father insists on a reconciliation, and Hieronimo cordially agrees. Even when the final ratification is given to Bell'-Imperia's marriage with Balthazar, Hieronimo is all smiles and acquiescence. He is willing to heighten the festivities with a play. Lorenzo, Balthazar, Bell'-Imperia and himself are to be the actors, though two of them demur at first at the choice of a tragedy. Still Lorenzo suspects no harm, for he is not present at the interview between the girl and the old man, in which she denounces his apparently weakening thirst for revenge, only to learn the secret of that gentle exterior. Unhappily, the delay of justice has preyed too grievously upon the mind of Isabella. There have been moments when she ran frantic. In a final throe of madness, having hacked down the fatal tree, she thrusts the knife into her own breast. The great day comes, and before the Viceroy of Portugal (father of Balthazar), the Spanish king, the Duke of Castile, and their train, Hieronimo's tragedy is acted. Real daggers, however, have been substituted for wooden ones. As the play proceeds, Bell'-Imperia kills Balthazar and herself, while Hieronimo slays Lorenzo. The only one left alive, Hieronimo, now explains the terrible realism behind all this seeming. Castile and the Viceroy learn that their children are dead, two of them killed to revenge the murder of Horatio. The drawing aside of the curtain at the back of the stage reveals that youth's corpse, avenged at last. Horrible scenes follow, Hieronimo being prevented from hanging himself as he intended. But, desperate, he bites out his tongue, stabs the Duke of Castile, and succeeds in killing himself. The Ghost of Andrea and Revenge, who opened the play and served as chorus to three previous acts, now close the play in triumph.
