This series is written by Sean French and Nicci Gerrard under the pseudonym of Nicci French.  This is the fourth in the series starring Frieda Klein, psychotherapist and sometimes murder investigator.  The other books take place in London,where Frieda lives along with her friends and family.  In this novel, she returns home, a place she has avoided over for twenty years.
An old classmate contacts Frieda because she feels she is becoming estranged from her teenage daughter perhaps because of her recent divorce.  She begs Frieda to talk with Becky.  After several sessions, Becky reveals she was raped and the details remind Frieda of the rape that happened to her twenty years ago.  No one believed her at the time, including her own mother which is why she left as soon as she could.  Now Becky's mother doesn't believe her daughter was raped.  So Becky hangs herself and
Frieda decides to find out who is responsible for destroying Becky's life.

 She goes back to Braxton to her mother's house and finds her ill and not at all welcoming.  So she stays with an old classmate, Eva.  As she visits with old friends, she learns of several other similar  rapes and murders that have occurred since she left.  In trying to piece together  the whereabouts of her friends during the night she was raped, she faces hostility and deceit.  She thinks she is facing this alone with only occasional help from her family and friends, but veiled serial killer, Dean Reeve, is  close behind her. 
Frieda faces her own ghosts in this book and as a result there are changes in her close relationships.  And there may be a cautiously blooming romance in the future.
What I like about this series, is that Frieda is her own person and while she has friends who value her, they accept her at face value.  I also envy that when she needs to think, she walks the streets of London.  If you like quiet mysteries, full of character, then you will enjoy this series.  Start with "Blue Monday".  Reviewed by Jane
