The Black Ice
The corpse in the hotel room appears to that of a missing LAPD narcotics officer. Rumours abound that the cop had crossed over - selling a new drug called Black Ice that had been infiltrating LA from Mexico - and the LAPD brass are quick to declare his death a suicide.
Detective Hieronymus 'Harry' Bosch isn't so sure. Prompted by odd, inexplicable details from the crime scene - and an undeniable attraction to the cop's widow - Bosch starts his own maverick investigation. An investigation that soon leads him over the border to Mexicali and into a dangerous labyrinth of shifting identities and deadly corruption.
