Murder, Sex, Revenge, Poker, and Polygamy ... and Trains

Cowboy Bob Smith is a famous poker player whose career is cut short when he's murdered in a particularly grisly fashion. After a second poker player is killed in the identical manner, it seems as though a sick killer is on the hunt for
world champion players.
Noah Packard, a defrocked doctor-turned-detective, and his unlikely cohort a sharp-tongued ex-stripper, Jesica "One S", are hired to find the suspected serial killer, but they don't have much to go on.
To find answers, the pair wades through a mire of gambling, racism, violence, and revenge, injected with a dose of the supernatural. They descend into the slimy underbelly of Las Vegas and the horrors of polygamous cults in Southern Utah, all while struggling to stop a killer before he strikes again.
