It's amusing to see Ms. Cornwell present her case with the audacious words Case Closed right in the title. Er, psst, it's called research - might want to look into doing more of it next time out. She used to claim to do it for her other books, but now she's seemingly taken a page out of Ambrose's style book, or whomever she actually got her plagarism ideas from, or he his for that matter.
Much of this material that is presented in this book as *groundbreaking* and *brand. spanking. new.* has actually been covered many times, in books, magazines, and of course ad naseum on the WWW. Most notably, the core theme here, accusations that Mr. Sickert is JtR, or at least an accomplaice, or one of several real killers (OJ anyone?) has been presented again and again. Most notably, if only for it's controversy at the time, was 1978's "Jack The Ripper: The Final Solution" by Stephen Knight. Mr. Knight's tale dared to develop from hint to whisper to shout, that the highest levels of British government and, eek! not unlike this very week!, even the Crown may have been involved in convoluted coverups. Those weren't new ideas in 1978, much less now a generation on.
Well, at least Ms. Cornwell seems as sure of herself as Mr. Knight was of himself during his fifteen minutes.
Two stars for balls, or should I say guts? None for originality. If you're a RipperPhile or live under a rock, by all means buy it. If not - Next!
