The Trees is a page-turner that opens with a series of brutal murders in the rural town of Money, Mississippi. When a pair of detectives from the Mississippi Bureau of Investigation arrive, they meet expected resistance from the local sheriff, his deputy, the coroner, and a string of racist White townsfolk.

The murders present a puzzle, for at each crime scene there is a second dead body - that of a man who resembles Emmett Till, a young black boy lynched in the same town 65 years before.

The detectives suspect that these are killings of retribution, but soon discover that eerily similar murders are taking place all over the country. Something truly strange is afoot. As the bodies pile up, the MBI detectives seek answers from a local root doctor who has been documenting every lynching in the country for years, uncovering a history that refuses to be buried.
