"Valuable Information"
Yes. I have already read another of his books.
That anything is possible if you truly want it and are willing to focus on that one thing and work until you accomplish it.
"Surprise"
Probably not.
This was a decent mystery story but there is absolutely no relation to Sherlock Holmes except the character names. I mistakenly expected more of a connection. I was also very surprised by some explicit homesexual sex descriptions. There should have been a warning in the product information.
