Simon Temple: It’s one of Evelyn Waugh’s earliest works, written in about 1930, that I just happen to be re-reading. I read it about 10 years ago and really enjoyed it. I happened to see it on the shelf when I was heading out, knowing there was a journey ahead, so I just grabbed it as I didn’t have a book on me. I don’t use the Underground that frequently. If you’re just travelling from point A to point B, you may as well fill the time doing something.
