Jack the Ripper is the ultimate whodunit. The Whitechapel Murders of 1888 remain unsolved and hundreds of theories have been suggested as to the killer's identity. However, many of the suggestions naming the infamous Ripper remain ill informed and, quite frankly, ludicrous - until now! The authors of this book are all members of The Whitechapel Society, the world's largest organisation for the study of Jack the Ripper. Each has spent many years researching a particular suspect and the results of their latest, cutting-edge investigations are published here for the first time. Based on indisputable facts and concrete evidence, the cases put forward in this collection allow readers to decide exactly who they believe is the man behind the myth. With each chapter discussing a separate suspect in detail, this book is the ultimate guide to the most famous criminal investigation in British history.
