Harry Bosch investigates the drug-trafficking underworlds of inner city Los Angeles and the wastelands of Mexico.
When a body is found in a hotel room, the press soon pick up on the case: it appears to be the body of a missing LAPD narcotics officer, apparently gone to the bad. The rumours were that he had been selling a new drug called Black Ice that had been infiltrating Los Angeles from Mexico.
The LAPD are quick to declare the death as a suicide, but Harry Bosch is not so sure. There are odd, unexplained details from the crime scene which just don't add up.
Fighting an attraction to the cop's widow, Bosch starts his own maverick investigation, which soon leads him over the borders, and into a dangerous world of shifting identities and deadly corruption.
