The Real Life of Sebastian Knight, the first novel Nabokov wrote in English, is a tantalizing literary mystery in which a writer's half brother searches to unravel the enigma of the life of the famous author of Albinos in Black, The Back of the Moon, and Doubtful Asphodel. A characteristically cunning play on identity and deception, the novel concludes " I am Sebastian, or Sebastian is I, or perhaps we both are someone whom neither of us knows."
