Bosch got a new partner who is a bit afraid of his way of doing things. Going head to head with the FBI and whoever like to stand in his way of investigation.
So... this is a not a straight forward murder. A man was first blackmail and then killed by possible terrorists.
This is a large print version and it is shorter than most of his other books.
The constant in a Bosch novel is lies. FBI lied to Bosch and Bosch lied to FBI.
In the last 2 chapters when the killer is being discovered. It is going to be a surprise.
