This is a story from the Grimm's Fairy Tales collection.

Here are some of the most enchanting fairy stories of all time. The Brothers Grimm conjure up a world of fantasy, hope and good fortune where the princess meets and marries the right prince (even if he once was a frog), and where the cruel witch, the arrogant wife and the greedy wolf get their comeuppance. It is a magical world which we must all inhabit at one time in our lives and which are as important in this computer age as ever before.
