I've read J.K. Rowling's website and FAQ. I've read every interview with her that I know of. I've read all the books many, many times. I've read the HP Wikia, the Lexicon, essays, fan fiction, and even been to panels that touch on the subject of charms at HP cons.
I would like a definitive explanation on the Fidelius charm.
Who can tell who what, what happens when the Secret Keeper dies, who can say what to who? I've read so much contradicting information -- I'm pretty good at figuring these things out, but I'm stumped on this one.
How exactly does the Fidelius charm work?
