ected conspiracy against
his life, despises the servile adulations of the Russians, and is for
sending them away. The Poles, on the other hand, by whom he is
surrounded, are rude and violent, and treat the Russians with contempt.
Demetrius longs for a meeting with his mother, and sends a messenger to
Marina.

Among the multitude of Russians who throng around Demetrius in Tula
appears a man whom he at once recognizes; he is greatly delighted to see
him. He bids all the rest withdraw, and so soon as he is alone with this
man he thanks him, with full heart, as his preserver and benefactor.
This person hints that Demetrius is under especial obligations to him,
and to a greater extent than he is himself aware. Demetrius urges him to
explain, and the assassin of the genuine Demetrius thereupon discloses
the real facts of the case. For this murder he had received no
recompense, but on the contrary had nothing but death to anticipate from

had attended upon all occasions without being observed, he is now
revenged. His tool, the false Demetrius, rules over Russia in Boris'

is awful. In the moment of the highest rage and despair, the assassin
drives him to the extreme of endurance, when with a defying and insolent
air he demands his reward. Demetrius strikes him to the earth.

Soliloquy of Demetrius. Internal conflict; but the feeling of the
necessity for maintaining his position as Czar is triumphant.

The delegates from Moscow arrive, and submit themselves to Demetrius.
They are received gloomily, and with a menacing demeanor. Among them is
the Patriarch. Demetrius deposes him from his dignity, and soon
afterwards sentences to death a Russian of rank, who had questioned the
authenticity of his birth.

MARFA and OLGA await Demetrius under a magnificent tent. Marfa speaks of
the approaching interview with more doubt and fear than hope, and
trembles as the moment draws near which should assure her highest
happiness. O
