I agree a little more nuance and repeated acknowledgement that her own hypotheses were based on educated guess work and unreliable sources would have removed some of the controversy and improved the book.

But given the scarcity of reliable information (due to reporter bias and poor record keeping) I think she's done an absolutely astounding job to gather as much biographical information as she did. She turned them from bodies on a mortuary slab to living, breathing women who lived heartbreakingly difficult, troubled and sad lives, and as she described them bedding down in the gutter I found myself desperately wishing that someone could have come along and shaken them awake and moved them on before they could become the Ripper's victim. The book left me angry at their fate, and the fates of thousands of women like them. She brought them back to life. It's not a perfect book, but it's an amazing one nonetheless.
