Yes, the protagonist is a deranged pervert - that we all know from the pearl-clutching shock that remains associated with the book after so many years. But it is so much more than a lurid tale of debauchery. In fact, after reading, it feels quite the opposite. Nabokov's artful prose rivals the very greatest modern writers you will have ever read. His skill with imagery and coined terms is magical, while the vehicle of his unreliable narrator carries you deep into and around the edges of madness and obsession. Simply a fantastic read.
