Eleanor Murphy Book Club: Murder Carries A Torch

Petite Patricia Anne and hefty Mary Alice, series sister-sleuths in their sixties, hasten to the aid of their cousin Luke, whose wife has apparently run off with a painter. They search for the woman and discover a dead body in a "snake-handling" church; much-married Mary Alice meets and flirts with the investigating sheriff; police find the painter dead; and someone "hides" a rattlesnake in Mary Alice's car. Set in Alabama.
