Query: Unconvincing, But An OK Read

The Black Dahlia murder mystery, which is one of this country's most talked-about murder cases is presented here by Janice Knowlton in a fashion that makes for great reading, but is of little actual signifigance to the case. Knowlton writes that Elizabeth Short (The Black Dahlia) died at the hands of her abusive father, George Knowlton. Some parts of the book are great, some are plodding, but overall, this is just fictional. If you want a great book on the case, buy "Severed," by John Gilmore, which is probably the only "real" book on the case.
