Doria’s father dies, and Nina’s consents to his marriage; so that we see them, at the opening of the third act, the picture of connubial bliss, in a garden belonging to the Duke’s palace at Genoa, exchanging sentiments which would be doubtless extremely tender if they were quite intelligible. A great deal is said about genius being like love; which gives rise to a simile touching a rose-bud in a poor poet’s window, and other incoherencies quite natural for persons to utter who are supposed to be in love. This peaceful scene is interrupted by an alarm of war; and the Prince goes to fight the Florentines.

The battle takes place between the acts; and we next see the Genoese halting near their city after a victory. Doria, who in the first act has been represented to us as an exceedingly gay young fellow, is here described as indulging, in his tent, his old propensities; having brought away, with other trophies, a fair Florentine, who is diverting him with her guitar at that moment. This is excellent news for Spinola; the more so as we are soon made to understand that Nina, being impatient of her husband’s return, has fled to his tent to meet him, and discovers the fair Florentine in the very act of guitar-playing, and her spouse in the midst of his raptures thereat.

A scene follows, in which Spinola, as a new edition of Iago, and Nina, in the form of a female Othello, get scope for a great variety of that kind of acting which performers call “effective.” The wife—in this scene really well-drawn—will not believe Doria’s falsehood, in spite of strong circumstantial evidence. Spinola offers to strengthen it; and the last scene of this act—the fourth—presents a highly melo-dramatic situation. It is a street scene; and Spinola has brought Nina to watch her husband into her rival’s house. She sees him approach it—he wavers—she hopes he will pass the door. Alas, he does not, and actually goes in! Of course she swoons and falls. So does the act drop.

The entire business of the last act is to bring about the catastrophe; and, as not one step towards it has been previously taken, there is no time to lose. Spinola, therefore, is made not to mince the matter, but to come boldly on at once, with a bottle of poison! This he blandly insinuates to Nina might be used with great effect upon her husband, so as effectually to put a stop to future intrigues with any forthcoming fair Florentines. She, however, declines putting the poison to any such use; but, nevertheless, honours Spinola’s draught, by accepting it. The villain expresses himself extremely grateful for her condescension, and exits, to make way for Doria.

Directly he appears, you at once perceive that he has done something exceedingly naughty, for his countenance is covered with remorse and a certain white powder which is the stage specific for pallor. The lady complains of being unwell, and her husband kindly advises her to go to bed. She replies, that she has a cordial within which will soon restore her, and entreats her beloved lord to administer the potion with his own dear hand; he consents—and they both retire, and the audience shudders, because they pretty well guess that she is going to toss off the dose, of which Spinola has been the dispensing chemist.

And here we may be forgiven for a short digression on the subject of the dramatic Materia Medica, and poison-ology. The sleeping draughts of the stage are, for example, generally speaking, uncommon specimens of chemical perfection. When taken—even if the patient be ever so well shaken—nothing on earth, or on the stage, can wake him after the cue for his going to sleep, and before the cue for his getting up, have been given; while it never allows him to dose an instant longer than the plot of the piece requires. Then as to poisons; there are some which kill the taker dead on the spot, like a fly in a bottle of prussic acid; others, which—swallowed with a sort of time-bargain—are warranted to do the business within a few seconds of so many hours hence; others again there are (particularly adapted for villains) that cause the most incessant torment, which nothing can relieve but death; a fourth compound (always administered to such characters as Nina Sforza) are peculiarly mild in their operation—no stomach-ache—no contortions—but still effectual.

The contents of the phial given to Nina by Spinola are compounded of the second and fourth of these formulæ. The drink, though deadly, is guaranteed to be a mild, rather-pleasant-than-otherwise poison, warranted to operate at a given hour; one calculated to allow the heroine plenty of time to die, and to make her go off in great physical comfort.

Nina has taken the poison; but, having a peculiar desire to die at home, orders a “trusty page” to provide horses for herself and attendant secretly, at the northern gate, that she may return to her native Venice. With this determination we lose sight of her.

Doria is aroused by a hunting-party who have risen so early that they seem to have forgotten to take off their nightcaps, to which the Italian hood, as worn by the Haymarket hunters, bears an obstinate resemblance. The Prince discovers his wife has fled, and orders his chasseurs to divert their attention from the game they had purposed to ride to cover for, and to hunt up the missing Nina.

“In the deep recesses of a wood” Spinola and Doria meet, the latter having, by some instinct, found out his pseudo-friend’s treachery; of course they fight: Doria falls; but Spinola is too great a glutton in revenge to kill him till he knows of his wife’s death, so, after gloating over his prostrate enemy, and poking him about with his rapier for several minutes, all he does is to steal his sword; this being found upon him by some of the hunters, who meet him quite by accident, they suppose he has killed Doria, and so kill him. Thus, Spinola being disposed of, there are only two more that are left to die.
