Now this is an easy one. I'd finished an audio book and was wanting to get back to my favorite back-up audio, something featuring Sherlock Holmes read by Derek Jacobi.
In this case, the audiobook I turned to is the last collection of Holmes short stories: The Casebook of Sherlock Holmes.
Nothing could be more splendid than the way Jacobi characterizes Holmes, lightly and with a touch of playfulness ... almost like a seriously minded Bertie Wooster. It lightens up the Holmes-Watson relationship quite a bit and makes these a sheer delight. I'm on the third or fourth story and they do seem to be more of a mixed bag than the usual lot, but Jacobi's narration makes me simply enjoy the ride no matter where it takes us.
