1964 - Life on the North Dakota farm hasn't always been easy for Marjorie Trumaine. She has begun working as a professional indexer to help with the bills - which have only gotten worse since the accident that left her husband, Hank, blind and paralyzed. When her nearest neighbors are murdered in their beds, though, Marjorie suddenly has to deal with new and terrifying problems. Sheriff Hilo Jenkins brings her a strange amulet, found clutched in the hand of her murdered neighbor, and asks her to quietly find out what it is. Marjorie uses all the skills she has developed as an indexer to research the amulet and look into the murders, but as she closes in on the killer, and people around her continue to die, she realizes that the murderer is also closing in on her.

Sonny Burton was forced to retire from the Texas Rangers after taking a bullet from Bonnie Parker in a shoot-out. The bullet so damaged Sonny's right arm that he had to have it amputated. While Sonny struggles with recuperating and tries to get used to the idea of living a life with only one arm, Aldo Hernandez, the hospital's janitor, asks Sonny to help find his daughter and bring her back home. She has got herself mixed up with a couple of brothers involved in a string of robberies. Sonny agrees to help, but is more concerned about a wholly different criminal in town who has taken to killing young women and leaving them in local fields for crows to feast on. Just as Sonny is able to track down Aldo's daughter, he comes to an uncomfortable realization about who might be responsible for the string of murders and races to nab the killer before another girl is left to the crows.
