This moment also stuck out to me. Part of Dostoevsky's genius here is to extend the uncertainty of the situation as long as humanly possible, and Porfiry Petrovich is his conduit for doing so. Just before the supposed wink, the narrator recounts that Petrovich "suddenly looked at (Raskolnikov) somehow with obvious mockery." The word "somehow" implies the anguish Raskolnikov is experiencing for lack of knowing for certain what Porfiry is actually aware of with regard to the crime. This contributes to the ever tightening grip of suspense which is built up simultaneiously as Raskolnikov descends into madness.

I totally agree. My reading of DQ so far is that his misunderstanding of the situations he finds himself in, be they hallucinations or poor judgement, reflect a greater personification of attitudes toward shifts in European societal structures and the almost melancholy undertones of change. Don Quixote is at once an individualist and someone seeking public recognition. However nuclear his views, he propounds a far simpler perspective that is no doubt appealing to men who feel their only outlet of power is to gain kleos through physical prowess and courtly love.
