When Jo's website first was published, there was this hidden early draft of PS in which the Stone was found in the Potters' safe and the trio were all, "Uhhhh" about it.
But I can't find it. :(
Did I imagine this? Does anybody else remember it?? Am I totally crazy???
ETA: FOUND IT!
On JKR's website, there's a phone in the upper left hand corner. Dial 62442 then press the call button. It's really hard to read, but it's really interesting! Maybe I'll try to transcribe it...
