In the scorching, drought-plagued summer of 1934, as wildfires burn across Utah, Detective Lieutenant Art Oveson faces a unique assignment. Salt Lake City's mayor has tapped him to revive the Anti-Polygamy Squad, a unit formed years earlier for the purpose of driving out the city's "plural marriage zealots." As a Mormon ashamed of his own ancestors' part in the church's polygamist past, Art is eager to do his part to flush out the extremists. Then a local polygamist "prophet" is brutally murdered and a shell-shocked young girl is found at the scene of the crime. Is she the victim's daughter, a child bride, or the murderer herself? Art attempts to investigate the death, as well as discover her identity, despite a "wall of silence" put up by polygamists who would rather mete out their own rough justice. Soon, however, Art discovers that the sect has much more to hide than he thought. Historian and Hillerman Prize-winning author of City of Saints Andrew Hunt returns to 1930s Salt Lake City in this deeply researched mystery. A Killing in Zion portrays a city and a religion struggling to grow and shake off a notorious history that has not yet become a thing of the past.
