Keeper seem real, polyjuiced Peter into Sirius to pass along the
Secret to whoever needed to know?  Just a wild theory, I know, except
that it would help explain why even those closest to Sirius thought he
was definitely the Secret Keeper.  The other idea of course is the
note theory.  After all, if Harry could learn a Fidelius Charm secret
 through a note from Dumbledore, couldn't Peter pass along the secret
 through a note that could be shared around on a need-to-know basis? 
Do we know, after all, that he'd have to sign it for it to work?  We 
may assume this, but it is not definite canon.

Carol responds:
Okay, my primary objection (that Snape didn't know who the Secret
Keeper was) is out of the way, so I accept the possibility that he and
DD could *theoretically* have known the hiding place (the Secret)
without knowing who the secret Keeper was.

But where is the evidence that they knew or that James, Peter, and
Sirius hatched some elaborate scheme to inform them of the Potters'
whereabouts? It seems to me that the Potters would have wanted as few
people as possible to know--possibly Dumbledore but certainly not
Snape. AFAWK, not even Lupin knew the Secret. He certainly didn't know
the Secret Keeper's identity, and if a polyjuiced Peter pretending to
be Sirius had come to him, he'd have said something about it in the
Shrieking Shack. ("But you told me about Godric's Hollow!" "No, I
didn't. That was Peter, Polyjuiced as me!")

And where's the evidence that anyone besides Peter (who must have
retrieved and hidden Voldemort's wand) was at Godric's Hollow? Neither
James nor Lily mentions Snape in Harry's Dementor-induced memories.
James tells Lily that "he" (meaning Voldemort) is here. No one else is
mentioned. Peter could have hidden as a rat. But why on earth would
DDM!Snape be there? He says that he was at Hogwarts. Granted, he could
be lying to Bella, but surely if he were there, she'd already know?

And as I said before, Dumbledore's words indicate that *James* gave
him the Invisibility Cloak *before* Godric's Hollow, and it's most
unlikely that Snape would show up at GH wearing James's Invisibility
Cloak. (Imagine James's reaction to that!) If Dumbledore can become
invisible without a cloak and James trusts him enough to have Peter
(disguised as Sirius) tell him the Secret, wouldn't he have gone there
himself rather than sending Snape, whom James *wouldn't* trust?

Maybe James's "arrogance," as Snape calls it, consisted of turning
down Dumbledore's offer to become SK and choosing Black in his place,
refusing to believe that he was a traitor and a spy (as Snape believed
he really was)?

Also, if Dumbledore wasn't awakened by the sudden realization that he
knew the hiding place and therefore the Potters were dead (and/or
snape woke him to show him his fading Dark Mark), how did he know that
anything was wrong? Sirius Black didn't know. He just went to see
Pettigrew as planned to make sure that he was all right and became
suspicious when Pettigrew wasn't home and there was no sign of forced
entry. He knew the Secret but he didn't know that the Potters were
dead until he reached their hiding place, and he arrived after Hagrid
(possibly because he used his motorcycle instead of Apparating). If
he'd sensed the Fidelius charm breaking, he'd have Apparated there
instantly. Dumbledore, IMO, *didn't* know the Secret until after the
Potters were killed (even if he owned the property and lent it to them
in the first place, the Charm would have wiped away that memory).

Carol, who doesn't see either the evidence or the logic of the
IC/Snape hypothesis but is at least convinced that it's consistent
with DDM!Snape
