In that case, Eliza, I stand corrected.
When I was a child I only had 'Five Fall Into Adventure' - I loved it and read it over and over again. I asked my mother if I could have more Famous Five books for birthdays or Christmas (we didn't live anywhere near a book shop for me to buy one myself). She gave me a very tame, soppy Enid Blyton book about children who went on nature walks. She said she had looked at the Famous Five books but thought they were too boyish! Much as I loved her, she did spend years trying to turn me into the kind of person I never was and was never going to be.
