Potioncat:
My take on it.

No one sneaked in, crossed the lake, drained the basin, took the 
horcrux, left a fake, got out safely and went home. As difficult as 
it was for the Greatest Wizard who ever lived and the Boy Who Lived, 
I just don't think anyone else could get away with it.

Someone did switch the fake-horcrux-locket with the genuine horcrux 
prior to its being placed in the cave. So here's one possibility:
RAB is given the task by LV to place the Locket in a cave. RAB 
understands what the Locket is and has time to switch it, writing a 
note to go into the fake!horcrux and hiding the real one somewhere 
else. RAB and whoever else LV assigned, took the fake!horcrux to the 
cave, no spells/curses/hexes were yet in place. They dropped the fake!
horcrux into the basin and one of two things happened.
1) They then initiated the security spells themselves, and reported 
back to LV that the deed was done. In this case, RAB goes home. 
He/she may have been killed later.
OR

2) As soon as the fake!horcrux landed in the basin, the security 
spells were activated by magic LV had put into place and the treasure 
hiders, just like unfortunate pirates of yore, were killed. RAB is in 
the lake.

I believe RAB put the fake!horcrux in the basin because I don't think 
he/she could have gotten the real one out. And I don't think LV did 
it himself because he would have known the horcrux was fake. But I 
don't think the basin knew the difference. And it's very likely that 
RAB wasn't supposed to know what the Locket was.

And if I'm correct, Regulus' body was never found. So he isn't ruled 
out as RAB. (yet)
