This may have already been discussed, but in OoP, when Harry and 
everyone are cleaning out the glass cupboards, they find aheavy gold 
locket.  Any chance that could be the real horcrux?  It never says 
they threw it away, but that Kreacher kept trying to smuggle things 
out to his little nest.  I'm just trying to think if we have seen or 
been introduced somehow to that horcrux.  Maybe Regulus (if RAB is 
him, I think it is) hid it the last time he visited home.  I don't 
know, I have so many thoughts on horcruxes swimming around in my head, 
and I thought maybe someone else had some ideas.  Thanks for any 
help...
