The wolf thought to himself, 'What a tender young creature! what a nice plump mouthful - she will be better to eat than the old woman. I must act craftily, so as to catch both.' Collected by the German Grimm brothers, these folk tales have captured the imaginations of children and adults alike since they were first published in 1812. The best-known stories such as Rumpelstiltskin, Hansel and Gretel, The Frog-Prince and Little Red Riding Hood remain as popular today as when first told, although there is an underlying darkness and violence to the original stories.
