It's not much of a revelation to "speculate" that R.A.B. (the Horcrux-thief of book six) is Regulus Black, Sirius's brother (who was murdered by Voldemort 15 years before, aka the year Harry was born).
but i'm re-re-reading Order of the Phoenix, since HP is my comfort reading, and most of my other books are packed away for the move, and when the Gang cleans out the drawing room in Grimmauld Place, they remove (and presumably, throw out) a "heavy locket that none of them could open."
Merope is described as wearing a "heavy gold locket" that we know is Slytherin's.
So did HP and friends throw out the Horcrux? or maybe Kreacher nicked it from the rubbish sack??
More importantly, why do I spend so much time speculating about such things? I don't care nearly as much about what happens in the final book of The Series of Unfortunate Events (although i DO care quite a lot, and I'm eager for October 13 to roll around!), or what happens next in the Charlie Bone books (which I thought were sort of mediocre).
spells, spells, everywhere!
