Harry was about to call Sirius Black's house home. I reckon it's a 
setup job; not ESE!Dumbledore, but scheming, pragmatic DD.

When people know consciously (or instinctively) that they are dying, 
they usually put their affairs in order, and often "clean house!" 
Now that Sirius's house is clean I think that Harry is going to move 
in. I think he is going to find out something important at that 
house. 
What exactly was hidden up in the attic? 

He at least has to read the wizarding genealogy book that Sirius used 
to smash the spider like metallic creature that was crawling up 
Harry's arm (during the house decontamination scene).

I just hope they get rid of that horrid painting and the elf heads.
