Has anyone ever discussed the way that the Potter books seem to work 
kind of like mysteries in that there's often some sort of crime or 
shady activity going around, with the true culprit later being 
exposed. It seems like one of the truths of the series is that it's 
always the least likely person. (This might get to be a problem 
later, as everyone gets used to the pattern). 
Has anyone ever anticipated the twist? (I never have, at least so 
far).
