Nabokov begins his ''Strong Opinions'': 'I think like a genius, I write like a distinguished author, and I speak like a child'. In the interviews collected here - covering everything from his own burgeoning literary celebrity to Kubrick's ''Lolita'' to lepidoptery - he is never casual or off-guard. Instead he insisted on receiving questions in advance and always carefully composed his responses. Keen to dismiss those who fail to understand his work and happy to butcher those sacred cows of the literary canon he dislikes, Nabokov is much too entertaining to be infuriating, and these interviews, letters and articles are as engaging, challenging and caustic as anything he ever wrote. This title is part of a major new beautiful hardback series of the works of Vladimir Nabokov, author of ''Lolita'' and ''Pale Fire'', in Penguin Classics.
