This is a very cool book that is similar to The Blair Witch Project in its advertising. It presents itself as a lost manuscript written by Jack the Ripper, and the reader is left to wonder whether this is a work of fiction or indeed something from the original Saucy Jack. It's well-written in the style of Jack's time, and covers the author's earlier exposure to murder, why he stayed unmarried, and "explains" why Jack's short, violent killing spree stopped so suddenly. I loved the "this is real" style of the book, which gave a bit of shine that would be lacking otherwise. If you come into it knowing that it is absolutely a work of fiction, it can be a bit tedious and also a little uncomfortable when the author discusses his conversations with the victims before their deaths. It feels almost disrespectful. But when you read with the slightest hope that this work could possibly contain even the tiniest bit of truth, it completely changes the experience. I appreciated the little extras, like the epilogue, appendix, and facsimile of the "original" manuscript, all of which add to the illusion that this could be the real deal. Cleverly done, and I enjoyed it.
