Aleksander Petrovich Kuznetsov

 was a monk. He discussed the succession with Oksana Vladimirovna Kuznetsova. He didn't believe her story about the murder. He told the Ninth Doctor that he knew of Grishka. He thought that the Poles were invading, but the Doctor told him that this was a ruse as it was actually an alien invasion force. He later tried to get the populace to help him. Grishka died in his hands. (AUDIO: The False Dimitry)
