When C S Lewis? grandfather, Richard Lewis, hand-carved a wardrobe out of black oak to adorn his family home, he had little idea that it would provide his grandson with the inspiration for one of the world's best-loved children's stories.

The wardrobe stood for a time in the family home in Belfast, exerting a curious attraction for the children in the house. Two girls (both cousins of Lewis) remember sitting inside it, the door ajar, while the young C S Lewis held them spellbound with his stories. This young storyteller would become the author of one of the most famous books in the history of children's literature, The Lion, the Witch and the Wardrobe.

How God turned the atheistic C S Lewis into the most widely-quoted Christian writer of the twentieth century is as fascinating a story as any of the tales he told at that wardrobe door over a century ago.
