Writing from memory, when Arthur Weasley was attacked by Nagini, 
he had fallen asleep and the cloak had slipped from him!  The 
snake didn't need to use anything other than normal vision to 
see him.

I was speculating whether Hermione might visit Krum to gain 
access to Durmstrangs library, which would undoubtedly have a 
lot of info about Horcruxes.  There is probably a specific curse 
to destroy a horcrux, which Dumbledore may not have known due to 
his censorship of the subject at Hogwarts, and with which he 
could have avoided the injury to his hand.

Is Harry's parents home still magically concealed?  With the 
secret keeper still alive, and with one of the three people whose 
secret it was still alive, the house should be invisible to all 
except those whom Pettigrew has told the secret.  So how did 
Hagrid get Harry from the wreckage?  Unless of course it was only 
James and Lilly's secret, in which case the spell was broken when 
they were killed.

Now that the secret keeper for 12 Grimauld Place is dead, will 
it be possible for anyone to find the house, other than those 
Dumbledore told before?  Or is the killing of the secret keeper 
the end of the fidelius charm?
