What is the main conflict in Sunset Limited by James Lee Burke?

Sunset Limited by James Lee Burke is a story of the South and the secrets it holds. Set in New Iberia Parish, Louisiana, it is the story of Dave Robicheaux, bait shop owner and investigator for the New Iberia Parish Sheriff's Department. Born and raised in New Iberia, Robicheaux's childhood was less than happy. He still carries the emotional scars of his mother's infidelities and the sight of Jack Flynn's body, nailed to the side of a barn. As an adult, Robicheaux is sometimes plagued by memories of his time in Vietnam during the war and nightmares in which he relives the murder of his first wife, Annie. These days, Robicheaux enjoys the simple life in New Iberia. He lives with his wife Bootsie and their adopted teenage daughter, Alafair. He can often be found in the bait shop with his helper, Batist, or on the lake fishing with Clete Purcel.
