Query: It was a scam

It's important to realize that Chopin's purported letters to Delfina Potocka were thoroughly proven to be fakes; the two did have a more or less intense relationship, but little is actually known about it. Paulina Czernicka was a scam artist, and there was no conspiracy necessary to discredit her, as her work spoke for itself. It was easy to show, for example, that her letters used words that didn't exist in the Polish language in Chopin's time. While enjoying Igoshina's playing, please keep that in mind. If you are interested in Chopin's life, please read from reputable sources-- none of the films about him have much to do with reality, unfortunately.
