As with all of Sujata Massey's Rei Shimura books, we are immersed, not only in a mystery, but also in the mysterious culture of Japan. Here, in the fourth book, the particular focus is the world of Japanese animation, where rape is standard fodder for a comic book and even the Japanese are unsettled by extreme fans dressed up as characters. We also spend a surprising amount of time with foreign (non-Japanese) male strippers and even a few gangsters; all of which is to say that "The Floating Girl" seems just a wee bit extra exotic compared with the first three books. Even the sex, which Massey has always kept a few notches above the norm for "cozies" seems just a little spicier here. Following Rei Shimura's adventures has always been an exciting exploration of both traditional Japan, as well as its hip modern side, and this book continues in that mode. Fan's of Rei Shimura will welcome this addition, but I'm inclined to believe that the series is best appreciated starting from the beginning at "The Salaryman's Wife", an approach that allows for a gradual exposure to Japan and Rei.
