What is the author's style in Lolita by Vladimir Nabokov?

Lolita is a secular apologia pro vita sua by an imprisoned murderer and rapist. The novel consists of two numbered but untitled parts. The first part provides background on narrator Humbert Humbert's European background, including his analysis of why he is a voyeuristic pedophile, immigration to the United States, his settling in quiet Ramsdale somewhere in New England, marriage, widowhood, and setting on the road with his orphaned "nymphet" stepdaughter, Lolita. The second part follows H.H. and Lolita around the country on a meandering road trip
