It’s one of the oldest stories of them all, deeply embedded in our nature and our culture. In some ways it’s the story that defines our humanity and we have told it a thousand times in a thousand different ways.

It’s in the Bible with Joseph and his coat of many colours, it’s King Arthur pulling the sword from the stone, it’s the ugly duckling, Cinderella, Great Expectations, Moll Flanders and Jane Eyre.
