One golden summer afternoon in 1862, on the banks of the River Thames, the young Oxford mathematics don Charles Dodgson shared a picnic with three little girls, who asked for a story.

The adventure he created for one of the sisters, Alice Liddell, under the pen name Lewis Carroll, and the unforgettable characters he invented - the White Rabbit, the March Hare, the Mad Hatter, the Cheshire Cat, amongst others - have enchanted generations of readers. The world of Lewis Carroll, whose powerful imagination gave us the timeless magic of Alice in Wonderland and Alice Through the Looking Glass, is here vividly brought to life.
