'A Brief Guide to C.S. Lewis' explores Lewis's life, from his reconversion to Christianity under the influence of his friend J.R.R. Tolkien, which had such a profound influence on his writing - both fiction and non-fiction - to his marriage to American writer Joy Davidman Gresham and his battle with cancer. He died on 22 November 1963, a day before the first-ever episode of Dr Who, a TV series with many links to his Narnia stories was shown.
