Second tense, tightly wound tangle of a case for Hieronymous Bosch (The Black Echo, 1991). This time out, the LAPD homicide cop, who's been exiled to Hollywood Division for his bumptious behavior, sniffs out the bloody trail of the designer drug ``black ice.'' Connelly (who covers crime for the Los Angeles Times) again flexes his knowledge of cop ways--and of cop-novel clich‚s. Cast from the hoary mold of the maverick cop, Bosch pushes his way onto the story's core case--the apparent suicide of a narc--despite warnings by top brass to lay off. Meanwhile, Bosch's boss, a prototypical pencil-pushing bureaucrat hoping to close out a majority of Hollywood's murder cases by New Year's Day, a week hence, assigns the detective a pile of open cases belonging to a useless drunk, Lou Porter.
