Catlady, I agree that it must have been one of the four.  Following 
your assumption about the caster knowing who the secret keeper is, 
anyone else casting the charm would have been able to tell 
Dumbledore after James and Lily were killed that the secret keeper 
had been changed.  If our assumption is incorrect and the caster 
does not need to know the secret keeper's identity, of course the 
caster of the spell could have been anybody (probably Dumbledore).

Here's what makes me curious: Dumbledore knew that somebody close to 
James and Lily was passing information.  So why not make James or 
Lily the secret keeper?  Being the secret keeper doesn't prevent you 
from entering the building; after all, we know Dumbledore enters 
Grimmauld Place.  Wouldn't that be the safest bet of all?  Or is 
Godric's Hollow somehow James and Lily's secret in a way that 
Grimmauld Place is not Dumbledore's?

I am making one other assumption, I suppose: that Dumbledore does in 
fact enter Grimmauld.  We never actually see him there, so perhaps 
when he refers to going there he's actually on the front porch or 
something.  But this isn't really logical; why on earth shouldn't 
the secret keeper be allowed to enter?

Any ideas?

John.
