and, clearly on the edge of madness, asks Shuysky whether he has ever heard of dead children rising from their graves to question Tsars. Boris seeks assurance that the dead child the prince had seen in Uglich was really Dmitriy. He threatens Shuysky, if he dissembles, with a gruesome execution. The Prince describes the ghastly scene of Dmitriy's murder in a brief and beautiful aria ("In Uglich, in the cathedral"). But he gives hints that a miracle (incorruptibility) has occurred. Boris begins choking with guilt and remorse, and gives a sign for Shuysky to depart. [1872: The chiming clock again begins working.] Boris hallucinates (Hallucination or 'Clock' Scene). The spectre of the dead Dmitriy reaches out to him. Addressing the apparition, he denies his responsibility for the crime: "Begone, begone child! I am not thy murderer... the will of the people!"

Rangoni demands her obedience. Scene 2: Mniszech's Castle in Sandomierz. A Garden. A Fountain. A Moonlit Night (1604) Woodwind and harp accompany a pensive version of the 'Dmitriy Motif'. The Pretender dreams of an assignation with Marina in the garden of her father's castle. However, to his annoyance, Rangoni finds him. He brings news that Marina longs for him and wishes to speak with him. The Pretender resolves to throw himself at Marina's feet, begging her
