Query: Very weak, don't bother

Just about the weakest biography of anyone I've ever read - poorly written with little insight into the subject's character, this is a book that appears to have been thrown together with no care and little effort. An insult to the reader.For a good read on Martha Gellhorn, try Caroline Moorehead's Gellhorn: A Twentieth Century Life - a much more in-depth look at the subject and a superior quality of writing. Ms Moorehead is clearly a writer who knows her stuff. (Check out her latest, Human Cargo, for a powerful work on refugees).
