Bertram, the King's ward, has to do the King's bidding. He grudgingly accepts her; they are married. He leaves her, and goes to the wars in the service of the Duke of Florence, designing to see her no more. Helena withdraws from the Countess's house, and comes to Florence disguised. Bertram woos Diana, a maid of Florence. Helena impersonates her, receives her unsuspecting husband at night, takes from him a ring, and gives, in exchange, a ring given to her by the King of France. At the end of the war, Bertram, hearing that Helena is dead, returns to France, wearing the ring. The King sees it and challenges it. Bertram can give no just account of how he got it. Helena, quick with child by him, confronts him, with the ring that he left with her at Florence. Diana, the Florentine maid, gives evidence that Helena impersonated her on the night of Bertram's visit at Florence. Bertram accepts Helena as his wife, and the play ends happily. This play (whenever written) was extensively revised during the ruthless mood that gave birth to _Measure for Measure_. The alterations were made in a mood so much deeper than the mood of its first composition that they make the play uneven. Something, perhaps some trick of health, that made the mind clearer than the imagination, gave to Shakespeare for a short time another (and pitiless) view of human obsessions. It was a part of his belief that treachery is generally caused by blindness, blindness generally by some obsession of passion. In this play he treats of the removal of an obsession by making plain to the obsessed, by pitiless judicial logic, the ugliness of the treachery it causes.
