The Sign of Four

Vladimir Nabokov's Lolita is one of the best-known novels of the 20th century: the controversial story of Humbert Humbert who falls in love with twelve year old Lolita, beautifully repackaged as part of the Penguin Essentials range.

'Lolita, light of my life, fire of my loins. My sin, my soul. Lo-lee-ta: the tip of my tongue taking a trip of three steps down the palate to tap, at three, on the teeth. Lo. Lee. Ta.'

Humbert Humbert is a middle-aged, frustrated college professor. In love with his landlady's twelve-year-old daughter Lolita, he'll do anything to possess her. Unable and unwilling to stop himself, he is prepared to commit any crime to get what he wants.

Is he in love or insane? A silver-tongued poet or a pervert? A tortured soul or a monster? Or is he all of these?
