Scarpia presses his infamous proposals, when Spoletta returns, and speaking outside brings the news that Angelotti has poisoned himself rather than allow himself to be taken. A question as to the disposal of Cavaradossi brings the climax, and Tosca, by taking upon herself to give directions as to this, indicates her consent to Scarpia's wishes. But this master of deceit will not allow the release to be managed in any but his own way. He tells Spoletta that there will be an execution, but it will be a sham one, as in the case of another prisoner, by name Palmieri, the guns being loaded with blank cartridge only, and the victim instructed to fall and feign death. But Tosca wants more than this on her side of the bargain. Scarpia must give them both a passport out of the place, and as he goes to the table to write it Tosca's eyes catch sight of a knife on the table. In an instant her mind is made up, and as he returns to give her the paper, and to clasp her in a feverish embrace, she plunges the knife into his heart. The death-scene is perhaps a little prolonged, but seeing that it has been preceded by the torturing of Cavaradossi, it is at least logical that Tosca should remind him of the ghastly torture he inflicted on her loved one. The intensity of the scene is rounded off by the expressive phrase on a low monotone of Tosca, "And yesterday all Rome lay at this man's feet." The action to the finishing notes of this moving scene follows that of the play. Tosca searches for the passport, and snatches it from the fast locking palms of the dead man. With a shudder she rinses her finger with a serviette dipped in the carafe, and then puts the candles from the supper table at the head of the corpse, and taking a crucifix from the wall, places it on the breast, as the Scarpia theme in long-drawn chords is played softly by the orchestra. She goes out quietly as the curtain falls. The third act takes place on an open space or platform within the Castle of S. Angelo. At the back we see the dome of S. Peter's and the Vatican. The expressive prelude, and the opening song by a shepherd, are musically of great interest. It begins with a horn passage, and at the rise of the curtain it is still night, and we see the dawn break, and hear the many bells from the church towers, one of the most striking sounds of the Eternal city. The pastoral melody of the shepherd has a plaintive character, and he sings: Day now is breaking, The weary world awaking, Lending new sorrow And sadness to the morrow. And the sheep-bells come in with their jangle as the shepherd continues, with a suggestion of a love theme: If you could prize me To live I might try, But if you despise me I may as well die. Then the church bells continue the strain, now near, now afar.
