The person identified as the killer of five women in London East End in 1888 has never before been named a suspect in more than a hundred years of intense speculation. * The co-author of the book is the great-great-nephew of the killer, who discovered extraordinary evidence while researching his illustrious ancestor. He did not set out to find Jack the Ripper, and did not want to believe that his great-great-uncle could have been responsible. But the evidence is incontrovertible. * The killer was a very eminent man in his field, and naming him will cause huge shockwaves in the places where he is still venerated. * No one has ever been able to find any evidence linking any of the suspects to the victims. This book puts forward clear evidence connecting the killer to three of the five victims, and circumstantial evidence connecting him to the other two. * Patricia Cornwell's international bestseller PORTRAIT OF A KILLER may have established that artist Walter Sickert wrote incriminating letters, but all other authorities (including the police) have always believed that the letters were a hoax and were not written by the killer. * The authors prove that their suspect was in Whitechapel at the same time as the crimes were committed, and had the knowledge and skills which the nature of the murders required. * For the first time, the book presents a consistent and plausible explanation for every aspect of the case, meeting all the key criteria of method, motive and opportunity. It also explains why the murders stopped as suddenly as they started. * The authors have even discovered what they believe to be the murder weapon. Further forensic testing may be able to establish this beyond any reasonable doubt.
