"The Diary of Jack the Ripper: The Chilling Confessions of James Maybrick" generated a storm of media attention when it was published in hardcover. Reviewers coast-to-coast debated whether these gruesome journal entries are the genuine work of the notorious serial killer who terrorized London or a remarkably clever hoax. This new edition of "The Diary of Jack the Ripper" provides fresh evidence, published for the first time in the U.S., to support its authenticity: tests of the ink and paper show they could date from the year of the murders; clues pointing to Liverpool cotton merchant James Maybrick were left at the crime scenes, including his wife's initials on the bedroom wall of his last victim; and new information proves Maybrick was familiar with the Whitechapel neighborhood where the murders took place and had lived there with his mistress.
