**By Katie H.**At this point, just about everyone thinks R.A.B. isRegulus Black. It makes sense, certainly: Death Eater leaving the flock knows he's going to get whacked, so he sticks it to The Man one last time before they send him beyond the veil. Getting from R.A.B. to Regulus Black is easy. Too easy. Its so easy that its starting to feel like a red herring.
So I went back and scoured the books to find anybody and everybody else who could possibly be R.A.B. I tried every possible R, A, and B in the whole set and I've come up with a favorite: Borgin of Borgin & Burke.Its a long shot, I'll grant (we don't know his full name) but he's got a lot going for him:
1) The guy knows a thing or two about magical artifacts, particularly the dark ones. If anyone can tell a horcrux from a hole in the ground, its thisguy.
2) Formerly Tom Riddle's employer. This is significant, since the note reads "be a mortal once more". There's a feeling that whoever wrote the note would remember Voldermort from when he was a Regular Joe the first time. Most of the Death Eaters are too young, but Borgin & Burke hired an 18-year-old Tom Riddle. They'd rememeber ...
3) Borgin is partly responsible for cheating Voldemort's mother of her most prized possession. What possession, you ask? Nothing less than the very locket that's now gone missing.
4) There's a good chance Voldemort off-ed his partner,Burke. That would explain why he's expecting to be dead soon. Goodness knows he gets nervous enough around Death Eaters.
5) If Burke is dead, Borgin woul dbe the first to know. He'd also probably know that Hepzibah Smith was dead. He'd notice that his salesman has dissappeared,and he'd also probably be aware that the locket is gone. (Antiques dealers are known to scan obituaries and will readings for estate information.) So: guy who sold locket = dead, woman who bought locket = dead, lock = missing, and salesman = missing there's a good chance the locket is significant. Borgin's probably smart enough to put it all together.
