Query: Somewhat dark, but interesting, stories of Fujieda Baian

The original work by Ikenami Shotaro, "Koroshi no Yonin, Shikakenin Fujieda Baian" (Four Killers), was very popular in Japan. "Ninja Justice" is not a good name for the book. The 1973 adaptation of this book into the movie "Hissatsu Shikakenin" was also quite successful. In fact, I first came across these tales from watching the movie. Many subtleties in the original writing were lost in this English translation, but the storylines have been well captured.All the stories are interesting, and from one chapter to another they slowly bring alive the character of Fujieda Baian. At the end of the book you begin to like Baian, and you wish that there were more. Another seven volumes were published in the series, only the direct sequel, "Baian AriJigoku", was translated into "Master Assassin, Bridge of Darkness", but it has been long out of print. I believe that many readers would welcome a softcover reprint of this.
