Jay Porter, after some traumatic events involving his brother's death in Lamentation is back. He's working as an insurance investigator now. He learns while investigating a claim that a young boy went to a hardcore behavioral modification center for a minor crime. When he finds out there's a lot of similar cases he decides to find out what is going on, aided by an attractive young clerk. It turns out there's some ties to his brother's death as well.
This is a true hardboiled, noirish tale. Porter is having a hard time dealing with his relationship with his wife, his brother's death and just himself. An upbeat tale this is not. It is dark, moving and rich.
I do recommend reading Lamentation before you read this one though.
