The Last Coyote by Michael Connelly

As this novel opens, Harry Bosch is out of work.  Two weeks ago, he had gotten into a scuffle with his supervisor, Lt. Pounds, and it ended with Harry putting him through a glass window.  Now Harry is on suspension and can't come back until he is cleared by a psychiatrist.  Harry is not pleased to be visiting Dr. Carmen Hinojos and he certainly isn't sure if he can trust her.  But he has to go and what else does he have to do?

Except Harry knows what else he has to do.  Now is the perfect time to investigate the case he has put off for years, the one case that matters to him more than any other.  When he was eleven, his mother, Marjorie, had been murdered, leaving Bosch to a series of foster homes and institutions until he was able to escape by joining the military.  Her case was never solved.  Maybe it's time for Harry to look into it.

When he gets the files, he is infuriated all over again.  It's clear the case was just kicked down the road and never really investigated at all.  His mother was a prostitute and apparently, the murder of a prostitute wasn't high on the list.  But, it's high on Harry's list and he is determined to get to the bottom of it all.

As he investigates, he starts to see some shadowy connections.  His mother appeared to have been connected to some influential men, men in the district attorney's office and wealthy men with lots of pull.  Is that why her case stalled out?  As Harry tracks down the policemen who handled the case, he gets more evidence and in a side note, meets a woman he feels instantly attracted to and has a real connection with, something that doesn't happen often for him.  Everyone tells him that he should let it go but he can't.  Can he find the truth after all these years?

This is the fourth book in the Harry Bosch series and it gives the reader a lot of the background that makes up Harry's outlook on life and what is important to him.  There are plenty of twists and turns and the reader feels closer to Harry as he delves into his personal history.  This book is recommended for mystery readers.
