I listened to this in audiobook format from the library. It was an older audiobook and so the recording was not quite as good as they are on audible. For example, you could tell when the narrator needed to have a drink of water or clear his throat. I assume that with audiobooks being recorded now, that a lot of editing is done so that the listener does not hear this.
This is the first Sherlock Holmes story and we find out how Holmes met Watson. I really enjoyed this part of the book but became quite confused when all of a sudden the narrator started telling a story of a man and a young girl crossing Utah on horseback and being rescued by the Latter Day Saints (Mormons) and all about the Mormon church. It all becomes clear near the end of the book how this section in the United States relates back to the story in England but for a while I had no idea what was happening.
I gave this book 3 stars mostly for the beginning of the book when we find out the backstory of the Holmes and Watson meet up.
