This highly revelatory book, based on original research and completely new analysis, presents a compelling new suspect as the most notorious serial killer of all time: Jack the Ripper.Using a different analytical approach, for the first time, Sarah Bax Horton identifies a named perpetrator as Jack the Ripper by linking eye-witness accounts of the killer's distinctive physical characteristics to his official medical records. It argues that his broken left arm, which left him unable to work in early 1888, was one of his triggers to kill as part of a serious physical and mental decline caused by severe epilepsy.This new perpetrator fits the profile as stated by the police of the day: a local man of low class of whom they became aware after the final murder, when they launched an unsuccessful surveillance operation against him. As has never been done before, the author - an experienced former government researcher with specific expertise in research and analysis - formulates a complete analysis of the killer and his methodology, including how he accosted his victims, where he took them to their deaths, his unique modus operandi of a blitz-style attack, and how he escaped from each crime scene without detection.Each of the six murders - from Martha Tabram to Marie Kelly - is discussed and reconstructed as perpetrated by this man, with his escalating violence clearly demonstrated.
