River of Secrets - Hardback Book - A Wallace Hartman Mystery - by Roger Johns - 9781250110121 - St Martin's Press

Herbert Marioneaux, a Louisiana politician infamous for changing his mind on hot-button issues, has been murdered and his body posed to send a message. Baton Rouge homicide detective Wallace Hartman has to figure out who’s sending that message. DNA points to Eddie Pitkin, a social justice activist who also happens to be the half-brother of Wallace’s childhood best friend. But even with the combative history between Pitkin and Marioneaux, murder seems out of character for Pitkin, whose usual MO is to confront the wealthy and powerful with their inconvenient past. As Wallace digs deeper, she unearths a possible alibi witness, along with evidence of a deeply troubled relationship that points the finger of suspicion at Marioneaux’s son.
