I finished reading The Salmon of Doubt today. I very highly recommend that to anyone who enjoys Douglas Adams' other books. I'd only read his novels before and it was fascinating to read bits and pieces from him on all sorts of topics, from computers to his nose to the Brandenburg Concertos to atheism to travelling through Africa in a rhino suit. It also contains 11 chapters of the novel he was working on when he died, which was fun to read but frustrating to stop in the middle of. It's sad to think it will never get finished. The world lost a pretty amazing guy when he died.
