Graham Greene is frequently included in "novels everyone should read" and "best of the century" lists, and I've been meaning to read him for years. But I'd never made it a priority ... until I found out that Colin Firth narrates this version. This short novel might not hold the broader appeal of the other novels on this list, but I found it enjoyable and thought-provoking, and Firth's narration is pitch perfect. If you love Brideshead Revisited, read this immediately.
