Bitter Blood (1988)

THE DYING BEGAN ON A SUNDAY

The first bodies found were those of a feisty millionaire widow and her beautiful daughter in their posh Louisville, KY, home. Months later, another wealthy widow and her prominent son and daughter-in-law were found savagely slain in Winston-Salem, NC.
Mystified police firs suspected a professional in the bizarre gangland-style killings that shattered the quiet tranquility of two well-to-do southern communities. But soon a suspicion of that turned their focus to family.
The Sharp., the Newsons, The Lynches.
The only link between the three families was a beautiful and aristocratic young mother named Susie Sharp Newsom Lynch. Could this former child "princess" and fraternity sweetheart have committed such barbarous crimes? And what about her gun-loving first cousin and lover, Fritz Klenner, son of a nationally renowned doctor?
