“The Black Echo” One Sunday LAPD homicide detective Hieronymus 'Harry Bosch gets a call out on his pager. A body has been in a drainage tunnel off Mulholland Drive, Hollywood. The body looks like yet another OD, but Bosch isn't convinced the one new puncture wound amidst the scars of old tracks strikes an odd note. And something else: Harry knows him, Billy Meadows was a fellow tunnel rat out in Vietnam, running against the VC and against the fear they used to call the Black Echo. Harry let Meadows down once, he won't do it again
“The Black Ice” The corpse in the hotel room appears to be that of a missing LAPD narcotics officer. Rumours abound tat 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.
