The second part of the crime series with detective Harry Bosch.
"It's all a cesspool, man. It doesn't matter if you're at the bottom or the top. You're still swimming in shit."
A colleague of Harry's is found dead in a dodgy motel. From the suicide note, everyone assumes he committed suicide, but Harry knows not to put on the facts alone without a clear context. He suspects that the distributors of a new drug called Black Ice may have a vested interest in his colleague's death, and the discovery of two other dead people who played a role in the case reassures him of this view. Despite warnings to stay away from the case, Harry sets out on his own. The hunt escalates until the final denouement, which brings several unexpected twists.
The detective stories were also the basis for the successful television series Bosch starring Tito Welliver, currently in its sixth season.
