I received a free copy of this book in exchange for an honest review. This novel takes place in Japan and is about a serial killer with ritualistic overtones. Inspector Kotsuke Iwata leads an investigation into the murders of an entire family and this leads into all sorts of area including police corruption, a cult and, along the way, he suffers a lot of injuries (maybe more than one might consider plausible). This long novel is very interesting and keeps the reader on their toes and the characterisation is well-developed. Iwata, like many fictional detectives, is a troubled soul with a troubled past which is brought to light as the book progresses. He has suffered a great deal emotionally. I'd recommend this novel to any fans of Patricia Cornwell or Jeffery Deaver
