> CH3ed:
I agree with Ginny that the DEs knew Peter was the Secret Keeper 
(had Sirius been the SK and blabbed to Peter, that info still can't 
have been passed on to LV because in order to be able to find the 
Potters LV had to have heard it from the SK himself...like Harry had 
to read the note from DD in order to see 12 GP). So the most obvious 
conclusion is to extend that Snape knew that Peter was the betrayer 
and murderer(of 12 muggles) and not Sirius. 
However, it is still possible that Snape didn't know about Peter being a DE. <SNIP>


Le Green Dragon:
I think Ginny is right about the DEs knowing Pettigrew was the
traitor, not Sirius.  Snape was trying to get Harry expelled from
Hogwarts because of his hatred of James, and he couldn't let
Dumbledore know that he knew something which only the DEs could have
known.

When the DEs turned up at the graveyard, at the end of GoF, LV went
round talking to them, but he didn't name them all and they were all
masked.  I think it was Snape who said that LV operated in secrecy,
and that not all DEs knew who the others all were.
