City Of Bones by Michael Connelly

It's New Year's Day but that doesn't mean much to Detective Harry Bosch.  He's working anyway, holiday or not.  In fact, he catches a case when a man walking his dog reports that the dog has come back with a human bone.  The man is a doctor and insists he knows what a human bone looks like.  Harry goes out to see and looking around, finds the dump site and several other bones.

When the scene of crime technicians are through, the collected bones are sent to the medical examiner.  His report is that the bones are those of a young teen boy, probably twelve to thirteen.  Cause of death is blunt force trauma to the head.  Even more disturbing, the bones tell a story of continued child abuse with multiple fractures all over the boy's body.  Harry and his partner are determined to bring the boy's killer to justice even if this is a twenty-year old cold case.

Of course, things are never that simple.  Harry has met a new woman, a rookie cop who comes to the crime scene.  He knows it's probably not a good idea to get involved with someone from work but she's hard to resist.  Then there are his superiors who have always regarded Harry as a loner and a trouble-maker even if he is one of the best detectives the LAPD has.  There's always plenty of office politics to interfere in Bosch's cases.

Michael Connelly is one of the stellar names in police procedurals.  He has written over twenty Harry Bosch novels and Bosch is one of the detectives mystery readers recognize.  The character has even had an Amazon Prime TV series made to follow Harry's cases.  City Of Bones is the eighth Bosch novel and the one that Season One is based on.  Connelly is a solid writer and gives insight into a police detective's job and all the other factors that complicate an investigation.  This book is recommended for mystery readers.
