One of the French novelists, I can never remember accurately whether it was Maurois or Mauriac, said that 'the door slams shut on a writer before the age of 12' - meaning that all his raw material has been formed by then. It feels a bit early but I know what he meant. Likewise, perhaps all the influential books are those encountered in one's formative years. Fitzgerald had many faults - unpursued ideas, incomplete themes - but in Gatsby he created a sleek monster, a metaphor for that society of the rich dangerous to the heart even when passive . Review by Frank Delaney, whose books include 'The Sins of the Mothers' (Kirkus UK)
