The Confession of Jack the Ripper has an interesting story line, solidly written main characters (the police detectives duo) but sadly, the ending is a bit weak and underwhelming.
But I can appreciate how the author used a series murder case which took place in the modern time Tokyo (with a self-proclaimed Neo-Jack the Ripper as the murderer) to discuss the pro-and-con of organ transplantation from all sides and angles.
PS: and it isn't a good idea to read a novel about people being dissected (thankfully, after they were killed) and their entire internal organs being ripped out and removed before you ate your lunch. XD
