The Black Ice (Harry Bosch Series, Book #2) by Connelly, Michael - 1993

When a body is found in a hotel room, reporters are soon all over the case: it appears to be a missing LAPD narcotics detective gone bad. The police are quick to declare the death a suicide, but Detective Harry Bosch is not so sure.

Working the case, Harry is reminded of the primal police rule he learned long ago: don't look for the fact but the glue that holds them together. Soon he's making some very dangerous connections, leading to a bloody string of murders that wind from Hollywood Boulevard to the back alleys south of the border.

Now this battle-scarred veteran will find himself in the center of a complex and deadly game -- one in which he may be the next and likeliest victim.
