I know some people sneer at audio books because they're not really "reading," but I really enjoy them. I find the characters come more alive. My own acting abilities are really poor, and when I read a book, a lot of the characters talk in my head in a flat, calm voice, because that's my standard voice. So I love a good reader that can make the characters come alive. When the author is also an excellent writer, the combination is exquisite.
1. Josephine Tey, The Daughter of Time, read by Derek Jacobi
2. Dorothy L. Sayers, Strong Poison, read by Ian Carmichael (who also played Lord Peter Wimsey on PBS's Mystery series)
3. Any Rex Stout "Nero Wolfe" book read by Michael Prichard. I don't always like Michael Prichard's reading, but he has Archie Goodwin and Nero Wolfe down pat, and Stout's spare and perfectly chosen words come through superbly.
