This is an important book. Like others who have written, I grew up in an area not far from here, in a landscape dotted with oil wells, yet knew nothing of the murders detailed in this book. I am glad for the sake of the victims of this tragedy that this terrible injustice is now being brought to light.At the same time, I have some concerns about the way this book has been written. In an attempt presumably to maintain the reader’s interest, David Grann has chosen to write this non-fiction account as if it were a crime novel. Sometimes this leads to overwrought prose. As but one of many examples, he says of one character that he “would disappear into the streets with his gleaming English Bulldog.” The reference is not to a canine, but to the type of revolver the individual was reputed to own. It is difficult to imagine that this black gun was “gleaming” in the darkness of night, especially since there was no reason for him to have it drawn.More significantly, the decision to write in the manner of a sensational novel has affected the structure of the book. He begins with the story of two murdered individuals, setting forth a host of clues that, like in a good detective novel, one expects eventually to lead somewhere. For the most part, they don’t. As the story broadens, additional crimes and more characters are introduced so that to a large degree the events with which the story began fade into the background and some facts that appeared to be clues get dropped altogether. Perhaps this reflects the author’s own journey, as the book he set out to write turned into something else with the broad nature of the crimes uncovered through additional research. If that is the case, one can only wish he had taken the time to rewrite and give this story its proper frame.
