''Speak, memory'', said Vladimir Nabokov. And immediately there came flooding back to him a host of enchanting recollections - of his comfortable childhood and adolescence, of his rich, liberal-minded father, his beautiful mother, an army of relations and family hangers-on and of grand old houses in St Petersburg and the surrounding countryside in pre-Revolutionary Russia. Young love, butterflies, tutors and a multitude of other themes thread together to weave an autobiography, which is itself a work of art.
