Dust off the Bones: A crime fiction book

As someone who does not believe in an afterlife with punishment editions, and also would not strictly adhear to conventional ideas of reincarnation, death to me has always appeared to be a release from suffering. So the obsession with death as a punishment, the ultimate punishment, has always puzzled me, surely if punishment is really what you want then creating a worse life on earth is what is called for - and as we can see throughout history, we are really, really good at doing that.
