Step though the wardrobe - as historian Suzannah Lipscomb selects the creator of the Narnia Chronicles, CS Lewis.

The writer was a fascinating and extremely complicated man. Born in Northern Ireland, his mother died when he was a child, and his university career was interrupted so he could fight in the Great War.

Suzannah views his writings as deeply moving, as they have influenced her faith.

Presenter Matthew Parris is less convinced by the religious influence in his work.

But contributor to the Cambridge Companion to CS Lewis, Malcolm Guite sits firmly on Suzannah Lipscomb's side.

Produced in Bristol by Miles Warde.

First broadcast on BBC Radio 4 in January 2017.
