NEW YORK TIMES BESTSELLER * This superbly written true-crime story (The New York Times Book Review) masterfully brings together the tales of a serial killer in 1970s Alabama and of Harper Lee, the beloved author of To Kill a Mockingbird, who tried to write his story.

Reverend Willie Maxwell was a rural preacher accused of murdering five of his family members, but with the help of a savvy lawyer, he escaped justice for years until a relative assassinated him at the funeral of his last victim. Despite hundreds of witnesses, Maxwell’s murderer was acquitted-thanks to the same attorney who had previously defended the reverend himself. Sitting in the audience during the vigilante’s trial was Harper Lee, who spent a year in town reporting on the Maxwell case and many more trying to finish the book she called The Reverend.

Cep brings this remarkable story to life, from the horrifying murders to the courtroom drama to the racial politics of the Deep South, while offering a deeply moving portrait of one of our most revered writers.
