Strange Affair by Peter Robinson

 

In this fifteenth book in the DCI Alan Banks series, Banks is on leave when he gets a strange call.  His brother, Roy has called and asked Banks to call him back, saying it could be a matter of life and death.  The two brothers aren't close so Banks is surprised.  When he gets to Roy's house, Roy has disappeared, leaving everything behind including his phone.

Meanwhile, back at the station, there's a new murder.  A young woman was found on the expressway in her car with a gunshot wound that killed her.  There have been several other murders and attacks on the expressway in the past few years and Annie Cabbot, who is in charge, wonders if the cases are related.  But there is one strange thing that doesn't fit that theory.  The woman has a piece of paper in her pocket that says Alan Banks and his address.  Is this a friend of Alan's?

As the two cases progress, Roy's brother seems to have perhaps been mixed up in some shady business dealings.  He has been successful but always willing to skate close to the line.  Has he gotten involved with something dangerous?  The woman is found to have worked in an abortion clinic.  Had that been a factor in her death and how did she know Banks?  Eventually the two cases collide and become one, one that neither Banks or Cabbot will forget.  This book is recommended for mystery readers.
