HBP MUST have appeared in COS

Any takers for Snape as the HBP? I know this is a wild guess and 
that as head of Slytherin he should presumably be pure blood, but 
there are maybe inconsistencies in the Slytherin = pure blood thing. 
Presumably for example Tom Riddle is in Slytherin, though I have 
been glancing though COS and can't seee his house mentioned. He is 
certainly heir of Slytherin but he is half blood. It seems to me 
like a JKR trick to muddy the waters of the pure blood/half blood 
distinction. (Sorry about the pun.) I do think he will be someone we 
know and perhaps know well and this will be a revelation that will 
clarify a lot of other things. It could be what Dumbledore knows 
about Snape and what makes him trustworthy.

My other guess is Malfoy, just because I like the thought of him 
turning out not so pure blood as he always believed :-) 

Apologies if these speculations have already been made. I haven't 
time to go back far through the lists.
