Two Ripper experts examine unsolved murders—from Great Britain and around the world—that occurred during the era of the notorious killer. The number of women murdered and mutilated by Jack the Ripper is impossible to know, although most researchers now agree on five individuals. These five canonical cases have been examined at length in Ripper literature, but other contemporary murders and attacks bearing strong resemblance to the gruesome Ripper slayings have received scant attention. These unsolved cases are the focus of this intriguing book. The volume looks at a dozen female victims who were attacked during the years of Jack the Ripper's murder spree. Their terrible stories—a few survived to bear witness, but most died of their wounds—illuminate key aspects of the Ripper case and the period: the gangs of London's Whitechapel district, Victorian prostitutes, the public panic inspired by the crimes and fueled by journalists, medical practices of the day, police procedures and competency, and the probable existence of other serial killers. The book also considers crimes initially attributed to Jack the Ripper in other parts of Britain and the world, notably New York, Jamaica, and Nicaragua. In a final chapter, the drive to identify the Ripper is examined, looking at suspects as well as several important theories, revealing the lengths to which some have gone to claim success in identifying Jack the Ripper. "When it comes to the meticulous details of a murder, the minute-by-minute examination of a crime and its policing, Messrs. Begg and Bennett are the very best in the true-crime genre."—Judith Flanders, Wall Street Journal
