C.S. Lewis, J.R..R. Tolkien and their friends were a regular feature of the Oxford scenery in the years during and after the Second World War. They drank beer on Tuesdays at the 'Bird and Baby', and on Thursday nights they met in Lewis's Magdalen College rooms to read aloud from the books they were writing; jokingly they called themselves 'The Inklings'. C.S. Lewis and J.R.R. Tolkien first introduced The Screwtape Letters and The Lord of the Rings to an audience in this company and Charles Williams, poet and writer of supernatural thrillers, was another prominent member of the group. Humphrey Carpenter, who wrote the acclaimed biography of J.R.R. Tolkien, draws upon unpublished letters and diaries, to which he was given special access, in his engrossing story.
