I read the book. I enjoyed the book. I've even ordered the sequel. The stories are well written and engaging. But, I missed the mystery that I would associate with Sherlock Holmes and John Watson. The bulk of these nine stories made me feel like I was reading Indiana Jones Holmes. It's not a bad thing. It's just not how the book was marketed, it's reusing the characters in a different setting and in a different context. There may have been crimes committed. But, we generally know the criminal(s) and the story is the adventure of catching him/her/them.
I am sure that the people buying this book will enjoy it if they know going in that they're not buying a Sherlock Holmes mystery but a Sherlock Holmes adventure story. And, that needs to be what they're looking for.
