The Complete History of Jack the Ripper is by Philip Sugden. The most comprehensive look into the Ripper killings and the search for his identity. This book is extremely well researched and fascinating to read, but don't look for a definitive answer to the ultimate question. A great nonfiction read for fans of Ripperology and those just wanting a detailed introduction to once of history's most famous killers.
