Humbert Humbert, author of the manuscript, originally titled the Lolita, or the Confession of a White Widowed Male, died in 1952 in "legal captivity" (Fore.1), though we don't know what he was there for in the first place.
Humbert Humbert's attorney contacted the author of the Foreword and asked him to edit and publish it after Humbert's death.
Very few changes were made to the manuscript. Though the names were changed to protect the innocent, as they say – all, that is except Lolita because her name is so integral to the story.
If you care to do a little research in newspapers from fall of 1952, you would be able to confirm that "H.H."'s crime really occurred, though you won't find out why.
The fate of several people is announced – for example, a Mrs. Richard F. Schiller has died in childbirth – though who all of these folks are remains unclear.
Though the novel's subject matter is very racy, there are no "four-letter words" (Fore.4). Far from pornography, the novel teaches moral lessons.
Reader, be warned: the novel's narrator is a monster but a darned good writer and an honest one at that.
We have a lot to learn from the story, particularly about being more attentive guardians of innocent children.
