has fallen in love with an unknown man who has seen her in church. Hearing noises in the street Triboulet rushes out to investigate, at which point the king enters the house in disguise; he and Blanche profess their love. The king leaves again, but in the street the jester encounters a group of courtiers. They claim that, in accordance with the earlier plan of the jester they want to abduct Madame de Cossé. In fact, they have come after Blanche whom they believe to be Triboulet's mistress. This is to be the revenge of the courtiers on the jester. They trick him into wearing a mask blindfold and run off with the girl. When he hears her voice in the distance he realises what has happened. The next day the courtiers prevent Triboulet from entering the room in which Blanche is with the king. When she emerges she tells her father the whole story, which makes the jester determined to take revenge. As Saint-Vallier is taken to his execution Triboulet replies that the curse will soon act on the king. He goes to Saltabadil at an inn by the Seine and pays half the money for the murder. The king also arrives at the inn, where he waits for Maguelonne, the assassin's sister. When the monarch goes to sleep, Saltabadil plans to deal the fatal blow, but Maguelonne asks him to spare the man who has charmed her and instead to kill a random stranger and give that body to the jester. Blanche overhears and can see that the king is unfaithful but decides to save him by sacrificing herself. She enters and is mortally wounded. In the final act, it is midnight and a storm is passing. Triboulet returns to collect his prize in a sack and refuses Saltabadil's offer to help him throw it in the river, but just as he is about to do so, he hears the king's voice singing and realizes he has been duped. As lightning flashes, he opens the sack and sees that the body in it is his daughter; after asking forgiveness of him, she dies. A crowd is attracted by Triboulet's cries and believes he has killed someone, but a woman stops them from taking him away. A doctor also arrives at the scene and pronounces Blanche dead. Triboulet collapses, exclaiming "J'ai tué mon enfant!" ("I have killed my child!").
