Vanishing in the Haight by Max Tomlinson

Colleen Hayes killed her husband for molesting their daughter and went to jail.  She's now an ex-con who is acting like a private investigator.  The case she's given is a cold case that is over 10 years old.  The older man is dying and he wants to know who killed his oldest daughter.

Oceanview Publishing and Edelweiss let me read this book for review (thank you).  It will be published August 20th.

She begins asking questions.  As she stirs up attention to what she's looking into she's warned off by the cops.  She doesn't back down.  Then a retired cop she talked to and was going to give her a copy of his original police report doesn't make the meeting with her and is missing.  He's found.  Dead.  Now she's more determined than ever.

She talks to anybody who knew the dead woman and begins to put together an idea of what she thinks happened.  The only problem is that now the killer is on her trail...

With cops trying to kill her and the real killer after her, she has a lot of trouble.  There's more death but the lid comes off the case.  What's exposed is distasteful.  But even the big will fall.

I have to say that I liked the justice the wife of the retired cop dispensed.  She knew who killed him and she took care of it...
