Dave Robicheaux, his wife, and his buddy Clete Purcell have retreated to an old friend's ranch in Montana, hoping to spend their days fishing and enjoying their distance from the harsh, gritty landscape of Louisiana post-Katrina. But the serenity is soon shattered when two college students are found brutally murdered in the hills behind where the Robicheauxs and Purcell are staying. They quickly find themselves involved in a twisted and dangerous mystery involving a wealthy, vicious oil tycoon, his deformed brother and beautiful wife, a sexually deviant minister, an escaped con and former country music star, and a vigilante Texas gunbull out for blood. At the center of the storm is Clete, who cannot shake the feeling that he is being haunted by the ghosts from his past-namely Sally Dio, the mob boss he'd sabotaged and killed years before.

Nach dem erschütternden Hurrikan Katrina braucht Detective Dave Robicheaux eine Auszeit. Gemeinsam mit seiner Frau Molly und seinem besten Freund Clete will er sich auf einer Ranch in Montana beim Fischen erholen. Doch die vermeintliche Idylle wird schnell durchbrochen, als zwei Studenten brutal ermordet und bei der Ranch aufgefunden werden. Robicheaux wird unmittelbar in den Fall hineingezogen, in die Machtspiele derer, die in Montana den Ton angeben. Clete hat währenddessen allerhand eigene Probleme und wird schon bald von seiner kriminellen Vergangenheit heimgesucht.
