In "Wanted," a poem composed by Humbert Humbert (the narrator and main character in VN's novel Lolita, 1955) in a madhouse near Quebec after Lolita was abducted from him, there is a French stanza:
L’autre soir un air froid d’opéra m’alita:
Son félé - bien fol est qui s’y fie!
Il neige, le décor s’écroule, Lolita!
Lolita, qu’ai-je fait de ta vie? (2.25)
