This is the true story of an Alabama serial killer, and the trial that obsessed the author of 'To Kill a Mockingbird' in the years after the publication of her classic novel - a complicated and difficult time in her life that, until now, has been very little examined. Willie Maxwell was a Baptist reverend in Alabama; he also happened to be a serial killer. Between 1970 and 1977, his two wives and brother all died under suspicious circumstances - each with hefty life insurance policies taken out by none other than the Reverend himself. With the help of a savvy lawyer, Maxwell escaped justice for years. Then, the teenage daughter of his third wife perished. At the funeral, the victim's uncle shot the Reverend dead in a church full of witnesses - and was subsequently acquitted of the murder, thanks to the same savvy lawyer who had represented the Reverend for all those years.
