A CIRCLE OF WIVES

A CIRCLE OF WIVES by Alice LaPlante is a page turner.  When Dr. John Taylor dies in a hotel room in his own hometown, the police wonder if it really was a heart attack.  He had bruises on his body an at the autopsy they find potassium chloride in his system.  And then, many surprises pop up.  Like three wives and much more.  But which one did it or was it a disgruntled patient.  I guessed the murderer but was wrong and couldn't figure out how it happened.  Very good read
