Rutledge, David S. Nabokov's Permanent Mystery: The Expression of Metaphysics in His Work. 2010

This critical text examines the ways in which Vladimir Nabokov, one of the twentieth century's great writers, structured his works to encapsulate his metaphysical beliefs. It draws examples from Nabokov's novels, stories and nonfiction, revealing a startling consistency in his beliefs over the course of his career, even as the structure of his novels increased in complexity. At the heart of his work is a profound respect for what's missing, for unsolvable riddles, for questions even at the expense of answers. Nabokov's techniques--from wordplay to plotlines--reveal an enduring reverence for permanent mystery.
