In Broad Daylight is a 1988 true crime book by award-winning writer Harry N. MacLean,[1] detailing the killing of town bully Ken Rex McElroy in 1981 in Skidmore, Missouri.

The book won an Edgar Award for best true crime writing in 1989, was a New York Times bestseller for 12 weeks (charting at number 2) and was adapted into a television movie of the same name.

In Broad Daylight: A Murder in Skidmore, Missouri details the case of Ken Rex McElroy and his 21-year reign of terror throughout four counties in northwest Missouri, and the ultimate murder of McElroy, who was shot to death as he sat in his pickup truck on the main street of the town.

Critics have praised MacLean's lyrical depiction of rural, bucolic agricultural life in America's heartland – contrasted with a methodical and chilling description of the actions, causes and consequences of an ongoing nightmare of domestic terror.

The book, as well as the movie, chronicles the story of McElroy’s crimes, his killing on July 10, 1981, and the alleged coverup by the town of the identity of the killers for more than 30 years.
