After the departure of Geronte and his guests, Des Grieux, who has been told of Manon's whereabouts by the brother, comes in. The scene between them is musically full of emotional force, Des Grieux expressing his loneliness and despair at Manon's flight, while Manon deplores her weakness and assures him of her love in spite of all that the present situation entails. The highly dramatic duet works up to a fine intensity, and at the end their voices blend in a clever climax of a kind--a few strenuous reiterated notes in unison taking an upward leap at the finish--so characteristic of the composer. Their happiness is short lived, for Geronte comes in and puts them to confusion. After cajoling him into something like sweet reasonableness, Manon thinks the little affair will blow over. But her truly feminine desire for a compromise, a gentle slipping over of things, is not to be fulfilled. Des Grieux, when they are once more alone, tells Manon that her present life is impossible, that she must give it all up and fly with him. He has a fine broad melody when Manon tries to return to her plan of letting things go on as they are. Manon is moved by his intensity, and begs once again for forgiveness, and agrees to wholly give her heart to him. Lescaut now rushes in breathless to acquaint Des Grieux and his sister that Geronte has put the police on their track. The scene works up into a clever trio of quick movement, Manon imperilling herself and her companion by her desire to carry off as much spoil as she can lay hands on. Geronte, attended by a sergeant and two men, block the entrance, and Manon in her surprise and agitation drops her cloak, and the jewels roll to the floor. With this effective finish--Manon being arrested, as we may suppose, in this instance for larceny, and the grimness of the situation intensified by the rascally brother's double-dealing in the matter being hinted at--the act closes, Des Grieux being held back from rescuing his beloved, and uttering a cry of despair.
Before the third act comes a characteristic orchestral interlude, in which the Wagnerian plan of continuing the story by means of a symphonic tone poem is employed with individuality by Puccini. This intermezzo deals with two main ideas or phases, first the imprisonment of Manon, and secondly the sad journey to Havre, the port whence the _filles de joie_--how intensely sad is the irony of the description!--are to be taken over seas. To the score is appended a quotation from the Abbé Prévost's story, giving the clue to the strain of passion that comes in the music of this number, and blends skilfully with the sadness and the sense of movement which are its leading flavours, so to speak.
