I love to read and since 2011 I have been mostly listening to audiobooks because oftentimes there is nothing like a good narrator.
I like the genre, the sherlock holms like sleuthing and the british narrators, and this book did deliver that but it is clearly not geared towards adults. Many of the plot developments are obvious to an adult and if anyone had read Sir Conan Doyle's Sherlock Holmes novels, one particular development would have stood out like a sore thumb. I'll not say more because I don't want to spoil the story for anyone but as I said, to anyone who has read the original Sherlock Holmes it would be obvious. Even at the end, there would have been a blaringly obvious development being setup for the next book(s) in this series.
That said, I did enjoy the book to a degree, enough that I don't regret purchasing it but I do wish it was properly labeled. This should be in the teen or pre-teen sections.
