I know that lots of classics are free online, like on the kindle etc - does that mean they are completely free of copyright?
Or is there a difference between specific classic novels like Pride and Prejudice, and fairy tales which while generally having a named author like Grimm/Andersen have lots of different interpretations and retellings (so it's more the theme of the story, as opposed to the specific words which make up a book like P&P)
Basically I have a very little idea for a game which would overtly use the themes from a well known old fairy tale, so I'm wondering if there are any legal implications for this, or if fairy tales are completely public domain...
Any legal folk around to give me an idea please? :)
