Lipton suggests that "Jack the Ripper" (or "The Grim Ripper," as he calls him) was actually two people, Montague John Druitt and J.K. Stephen. The murders were committed in order to destroy certain evidence of homosexual activities amongst the British upper classes, particularly events surrounding the Apostles and Prince Albert Victor. Very little evidence is given to back up these claims, apart from an anagram Lipton creates out of the letter of the "From Hell" letter which includes the names Montague Druit, Eton and Cambridge.
Although the author obviously has done his homework and knows the basic subject matter very well, when it comes down to it, the theory has practically nothing to support it. The book itself is chock full of facts and illustrations, but is in bad need of an editor to organize it all and clean up the sentence structure in order to make it a more readable text.
Those with an interest in Druitt and/or the royal conspiracy theories may find some interest in this book. Otherwise, it is unfortunately not recommended.
