This story is based on real facts related to the opening of the Mussorgsky House Museum in St. Petersburg. And this is also a story of great love between two extraordinary people. Their feelings for each other, boundless devotion to Russian culture and love for Mussorgsky's music were able to bring to life all these unusual events. Obviously, the author was inspired to write all this by the life story of two great musicians - Galina Vishnevskaya and Mstislav Rostropovich. Nowhere in the text are their names mentioned. But the very outline of the events is a clear confirmation that it was they who served as the prototypes for these main characters.
