Picnic at Hanging Rock recounts the Appleyard College Mystery in which three schoolgirls and one governess go missing on the Hanging Rock in Australia.
I found this book to be relatively compelling in its mystery although it is never solved so if that is what you are looking for then this is not the book for you. The characters were developed to a point (as much as classical literature is) and I found the way Madam Appleyard thought quite humorous although I don't think you are supposed to. I'm not usually a fan of classic literature and this had similar issues to what I normally find such as a slow plodding pace, unrelated information and characters that are annoying. But the mystery was enough to keep me reading and although I knew it remained unresolved, I did have fun reading to the end. If classics are your thing then I would recommend but I won't read it again.
