I've read this idea before and dismissed it. But, I'm re-reading GoF 
now and am very surprised at how different Sirius is. (Most everyone 
else on this list noticed this much quicker than I have.) So now 
the  poisoning idea sounds reasonable to me.  My question would be: 
If JKR was having a character poisoned, why would she kill him in 
some other way before the poisoning was discovered?  As I was typing 
that sentence, I swear, a voice in the back of  my head said: To set 
us up for someone being poisoned in the next book! 

But, poisons are potions and potions are magic.  Can house-elves 
work this type of magic?  If it was Kreacher, was someone giving him 
the poisons?
