This book was very disappointing. I had expected some complex mystery since it was a Sherlock Holmes retelling and I got the opposite of that. I guessed who the murderer was withing the first 70 pages. The author made it way to obvious and I just wish there was more mystery to it. Also the relationship between Lock and Mori developed way too quickly. They legit said hi and then were basically best friends. Relationships don't work like that ever. This book was very unrealistic and it was very boring.
