Detective Dave Robicheaux travels to the mountains of Montana to help
his best friend and unearths a larger plot that threatens them both.
Oil speculator Weldon Sonnier is the patriarch of a troubled family
intimately bound to the CIA, the Mob, and the Klan. Now, the murder of a
cop and a bizarre assassination attempt pull Detective Dave Robicheaux
into the Sonniers' hellish world of madness, murder, and incest. But
Robicheaux has devils of his own--and they may just destroy the
tormented investigator and the two people he holds most dear.
