Hey
Remember how Kreacher left the house to go to the Malfoy's? How 
could he find his way back? I do not think DD would have told him 
the secret, because no one ever thought Kreacher would leave. So are 
house elves immune to Fidelius charm? If DD did tell him the secret, 
why would DD do that in the first place? Kreacher was not supposed 
to leave the house. If house elves can get around the Fidelius charm 
with their own form of apperation, wouldn't Voldemort want them on 
his side? A powerfully magical creature that could get into a house 
that no one else can get into without being told the secret? Seems 
like a valuable ally to me. Are we going to see Voldemort's version 
of S.P.E.W? Would Hermione approve? 

John who would like to see Hermione go over to the dark side to get 
S.P.E.W. off the ground.
