An anonymous tip puts Bosch on a case that has remained unsolved for decades, the vicious stabbing of a teenage boy whose body was found in an abandoned Old Hollywood restaurant. Cold cases are often the toughest: With no body, no murder scene, and no fingerprints, Bosch nevertheless gets lucky when DNA evidence from the murder weapon points to a known killer. But the DA insists that science alone is not enough - he needs the case to be bulletproof before he'll take it to court.Determined to speak for those who can no longer speak for themselves, Bosch has one chance to wrench a confession out of a cold-blooded killer, or risk letting him walk free for good.
