Under the banner of heaven

At the core of this book is an appalling double murder committed by a pair of Mormon fundamentalist brothers, Ron and Dan Lafferty, who insist they received a revelation from God commanding them to kill their blameless victims. He uncovers a shadowy offshoot of America's fastest growing religion, analyses the abduction of fourteen-year-old Elisabeth Smart (and her forced "marriage" to her polygamous kidnapper), and raises provocative questions about the religious belief.
