The eighth Harry Bosch novel, published in 2002, opens when a dog unearths a human bone in Laurel Canyon in the hills above Hollywood. The dog's owner, a retired doctor, recognizes the discovery immediately and calls the police. Harry Bosch responds, climbs the hill where the dog had been playing, and discovers the bones of a child that had been buried in a shallow grave more than twenty years earlier.
An autopsy reveals that the boy had been murdered, but there are precious few clues apart from the bones themselves. A case this cold will be almost impossible to solve, but for Bosch, this case, like virtually all his others, becomes personal and he simply won't let go of it.
Harry is, ultimately, able to identify the victim, but tracking down the killer will take all of the skills he has honed through the years. Along the way, he will acquire a new love interest, and, as is almost always the case, will find himself in conflict with the department's brass who are, at least in Harry's view, much more interested in protecting the department's image than they are in achieving some sort of justice.
This is another very good entry in the series, featuring the level of detail and insight into police procedure that readers have come to expect from Connelly. One of the particular joys of this book lies in the minor characters, beginning with the doctor whose dog discovers the bones, all of whom are very well-drawn and unusually interesting. The book ends with a particularly shattering climax which will leave readers very anxious to get to the next book in the series.
