The Black Ice

This is an okay book written by Michael Connelly. Narcotics officer Cal Moore’s orders were to look into the city’s latest drug killing. Instead, he ends up in a motel room with his head in several pieces and a suicide note stuffed into his back pocket. Years ago, Harry Bosch learned the first rule of the good cop: don’t look for the facts, but the glue that holds them together. Now, Harry’s making some very dangerous connections, starting with one dead cop and leading to a bloody string of murders that winds from Hollywood Boulevard’s drug bazaar to the dusty back alleys south of the border and into the center of a complex and lethal game – one in which Harry is the next and likeliest victim.

This is second novel featuring the detective Hieronymus "Harry" Bosch.
