David is the twelve-year-old narrator living in the rural town of Bentrock, Montana. Eager to be treated as an adult, he frequently eavesdrops on his parents' conversations to understand the adult world around him. He enjoys the freedom of the outdoors and harbors an innocent crush on his family's housekeeper.

Wesley is the 38-year-old sheriff of Mercer County who holds a law degree but works in local law enforcement to appease his dominating father. He prefers a non-violent approach to his job and keeps a small .32 caliber pistol in a dresser drawer rather than wearing it. His deep-seated prejudice against Native Americans heavily influences his initial handling of a serious criminal accusation.

Gail is a secretary who originally grew up on a farm in North Dakota. She feels out of place in Montana and longs for her husband to step out of his father's shadow to practice law elsewhere. Driven by traditional Christian values, she provides a strong moral compass for her household and readily believes the victims of abuse.

Frank is Wesley's older brother, a charismatic local doctor, and a decorated World War II veteran. Celebrated as the golden boy of the family, he enjoys immense privilege and operates with a sense of entitlement. He uses his medical practice and social standing to mask his predatory behavior toward Native American girls.

Marie is a young, vital Hunkpapa Sioux woman from North Dakota who cares for David while his mother works. Her sudden illness brings Dr. Frank to the house. She bravely refuses his medical treatment and reveals dark secrets about his behavior.

Julian is a wealthy rancher and the former sheriff of Mercer County. He is a commanding, old-fashioned patriarch who fully embodies the attitudes of the old West, solving problems with power, intimidation, and firearms. His open racism and absolute demand for family loyalty dictate the social dynamics of Bentrock.

Len is the current deputy sheriff of Bentrock, having previously served under Julian Hayden before working for Wesley. He is a recovering alcoholic who understands the unspoken rules of local law enforcement. He carries a large .44 or .45 caliber gun, unlike his current boss.

Enid is Julian's wife and the grandmother of David. She lives on the family ranch and supports her husband's dominating presence in the county.

Gloria is married to Dr. Frank Hayden. She enjoys the social status that comes with being the wife of a local war hero and medical professional, remaining largely insulated from his hidden crimes.

Daisy is Len's wife and the next-door neighbor to the Hayden family. She acts as a source of local gossip and provides informal confirmation to Gail about the open secrets regarding the town doctor.

Ollie is a respected local Native American elder in the Bentrock community. White residents view him as a model citizen, and Wesley consults him when gathering information about the reservation.
