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.
