It's Just a Spleen and a High School Ring - Joyce Spizer Foy - Bog

Private investigator Camellia "Mel" Walker flies from her home in Orange County, CA to East Texas in search of her son's former classmate, eight-year-old Angel Boudreaux. Mel knows better than to stand between an estranged husband with a long police record and his battered wife, but her search for justice spurs her deeper into the case once she finds a spleen that could belong to Angel. Along the way, she becomes embroiled in small town justice, feuding families, and joins a posse chasing convicts through the Big Thicket in this third installment of the Harbour Pointe Mystery Series.
