Once it got up and running it was highly enjoyable.
I am deducting a half a star, though, because I was not all that enthused with the book's narrator, Simon Prebble. I found his voices for Holmes and Watson to be far too similar--especially at the beginning--and I was having trouble keeping up with the story. Reading the kindle version along with it helped tremendously.
ETA: My copy of the audiobook also contains The Adventure of the Dancing Man, but I'm going to hold off on listening to that one until after Halloween Bingo concludes.
