'I had sent my heroine straight down a rabbit-hole . . . without the least idea what was to happen afterwards,' wrote Lewis Carroll, describing how Alice was conjured up one 'golden afternoon' to entertain a young girl. His dream worlds of nonsensical Wonderland and the back-to-front Looking-Glass kingdom depict order turned upside-down: a baby turns into a pig, time is abandoned at a disordered tea-party and a seven-year-old girl is made Queen. But amongst the anarchic humour and sparkling word play, puzzles and riddles, are poignant moments of nostalgia for lost childhood.
