>> Now if Snape had been present, it might have been a different 
story. He, I think, would have suspected a direct link to Salazar 
Slytherin, especially if he witnessed Regulus's death, even if he 
did not yet know about the Horcruxes (and, being Snape and trusted 
by DD, I think he did). But JKR has carefully made him absent from 
the scene, and no one present would have had any reason to see 
anything special in the locket. <<

   
  Hi Carol,
  I think you make some excellent points, but I have o disagree on one 
thing. I don't think Dumbledore told anyone else about the Horcruxes 
except Harry. I don't even think he's told MgGonagall about them, and I 
don't think he'd tell Snape either. Especially if Snape is DDM, spying 
on old Voldie, I think it would be extrememly dangerous for him to have 
told Snape. No matter how good an Occlumens he is, Voldie is a powerful 
Legilimens. No matter how much he trusted Snape, I don't think he would 
have taken that chance with such important information.
