I have to agree with everyone that this is the best of the series. The reason why is due to this being the least antagonistic the two mains have been to each other. The last chapter, while needed, nearly spoiled the book for me. It went back so easily to antagonistic and I wish they weren't. I get he wants to break the formula while still having Watson and Holmes style, but they worked because they were friendly towards each other. It might have been an act for the agent but eh. I look forward to the next book.
