A Circle of Wives

I just finished, A Circle of Wives by Alice LaPlante.  Dr. John Howard was found dead in a hotel room in a suspicious manor.  At his funeral, 3 wives come out of the wood work. Since John's death was suspicious the Palo Alto police start an investigation.  The story follows Samantha Adams, the lead detective and her investigation of the primary suspects,  the "circle of wives."  It's a mystery novel trying to find the murderer.  It was an easy read and a good story.
