Miyuki Miyabe (宮部みゆき Miyabe Miyuki) is a popular contemporary Japanese author active in a number of genres including science fiction, mystery fiction, historical fiction, social commentary, and juvenile fiction. Miyabe started writing novels at the age of 23. She has been a prolific writer, publishing dozens of novels and winning many major literary prizes, including the Yamamoto Shūgorō Prize in 1993 for Kasha and the Naoki Prize in 1998 for Riyū [The Reason] (理由). A Japanese film adaptation of Riyû, directed by Nobuhiko Obayashi, was released in 2004.
As with many other Miyuki Miyabe's novels, this one is a passable, entertaining story about a teenage son of a lower-middle level cop trying to solve an outrageous serial murder-dismemberment cases. The small town setting, characters and the murder mystery are all decently written, but the ending and the killer's motive...though it isn't bad but it isn't very outstanding neither.
Okay, the MCs of this story is a cop and his teenage son, I can't stress this enough but cops who are taking their jobs seriously, wanting to protect the innocents and righting the wrongs are usually fictional characters from novels and movies, etc. Real-life cops are another specie entirely.
