Body and Soil — Ralph M. McInerny

Till death do us part... After nearly thirty years of unhappily ever after, Wyler, Indiana's most affluent and argumentative couple decided to call it quits. At least Pauline Stanfield did. Hal Stanfield knew a divorce would unearth secrets - both the financial and extramarital kind - he preferred to keep buried.

But when Hal is found bludgeoned to death in his kitchen, attorney Andrew Broom finds himself defending a wife suspected of choosing murder over divorce. Soon he discovers that even the best-laid plans of marriage - or murder - can go dangerously awry when a twisted killer decides to play judge, jury...and executioner.
