For the first time in ages I haven't read the whole thread so sorry if this has been done to death in the middle.
LOL Clam - Wasn't Mr Pinkwhistle half person and half pixie, so he didn't gain acceptance from either community, and spent his time doing good deeds? Another classic from Enid Blyton.
I have read my Malory Towers and St Clares quite recently I'm afraid they are pretty rubbish. St Clares in particular - by the time the twins are in the third form they are so perfect they just drop out of the story. As someone said up thread, as an adult it reads very differently. The stereotypically dishonest, weaselly yet chic French characters...poor old Alma Pudden who has "trouble with her glands". I remember a sentence something like "Doris started to imitate Alma at a meal and the girls screamed with laughter. But there was no malice in the laughter now..." That's alright then 
There are better characters in Malory Towers but there's also a hell of a lot of sneering at people if not bullying them when they don't "fit in" ie they are not identical to the core clique. Poor old Gwen. It's hard to see with some of them exactly why they are "baddies". Remember June, aged 14, who everyone hated because she was "domineering"?
Even Darrell is a bit nasty, particularly in the first book, she's ever so mean to Mary-Lou.
The Chalet School....now that is something else!! Can we have a thread for people who are re-reading? I've read all mine too often, would love to discuss them with like-minded people! My dad binned all mine when I went to uni
but I have gradually bought them back, got a fantastic motley crew of new "retro" paperbacks, nasty 80s ones, one from the 60s, and some spanking new GGB ones that include literary analysis. I've got about 30, only 20 or so more to find....
