Brothers Ron and Dan Lafferty insist they were commanded to kill by God. In Under the Banner of Heaven, Jon Krakauer's investigation is a meticulously researched, bone-chilling narrative of polygamy, savage violence and unyielding faith. An incisive look inside isolated Mormon Fundamentalist communities in America, this gripping work of non-fiction illuminates an otherwise confounding realm of human behaviour.
Now a major TV miniseries starring Andrew Garfield.
