Everything She Ever Wanted book by Ann Rule

Joined in a romantic love that most people only ever dream about, Pat Taylor's marriage to Tom Allanson was all she ever wanted. Both came from fine Southern families, and both longed to recreate for themselves a plantation where they would raise horses, grow roses, and move with grace and style in the highest social circles of Atlanta; in short, to be the Scarlett O'Hara and Rhett Butler of their time. But scarcely two months later, their perfect world had erupted into family hatreds, terror, bloodshed and murder, The beautiful estate was mysteriously burned to the ground and Tom Allanson stood accused of the brutal slaying of his own mother and father. Before the terrifying truth about the perpetrator was revealed, other innocent victims were to suffer attempts on their lives as intricate family loyalties and cruel, obsessive jealousies were played out.
