Is there anything new to be read about Jack the Ripper, whose identity has been sought by countless "Ripperologists" for more than 120 years? This book answers an emphatic "Yes!" Drawing on recently discovered sources, the author argues that the Ripper's identity was no mystery to the police in 1891.

Police chief Sir Melville Macnaghten claimed to know the truth from "private information," but his source has remained unknown for more than a century. Here, the identity of Sir Melville's informer is revealed, explaining why the Ripper was disguised as an insane surgeon for public consumption. A number of photos are included, some never before seen.
