I love the Wells&Wong Mysteries, always unexpected. Keeps you guessing. The sudden plot twist is surprising, love the ending. I enjoy Hazel's authority, patiently explaining the ins and outs of Hong Kong life. I think it's fantastic how informative these books are, explaining quite historically accurately about the time Hazel&Daisy lived. Knowing more about Hazel's life explains a great deal about why she felt so out of place in England. It's good to have a book more about Hazel.
