In 1893, two years after the last Ripper murder, Detective Inspector William Race met with two journalists working for the Sun and told them that he knew the identity of Jack the Ripper: 25-year-old Thomas Hayne Cutbush. Race's superiors ignored Race's suspicions, so he went to the Sun. Two journalists set about investigating Cutbush, gathering startling new evidence and compelling eyewitness testimony. When they published their results they caused a sensation, leading to the now infamous and deeply flawed Macnaghten Report. In The Man Who Would Be Jack, the author re-examines Inspector Race's and the journalists' findings and uncovers startling new evidence to support the idea that Cutbush was indeed Jack the Ripper.
