The information here, including a very plausible theory of who was involved in the Dahlia killing, is very solid. But it's bogged down by messy writing. I frequently couldn't parse sentences or figure out what the writer was saying, and I am not a bad reader. If the quality of the writing had reached the level of the facts provided, this would be a classic of true crime writing. As it is, I'm sticking with 3.0 stars.
