I deliberated before giving this a five rather than four star rating, but I feel this is an absolute must read for certain readers, those who have read and enjoyed Mary Shelly's FRANKENSTEIN, Bram Stoker's DRACULA, novels by Wilkie Collins and Sheridan Le Fanu. This of course is also must reading for serious readers of any literature dealing with Jack The Ripper.I admit that I did find the first 63 pages very laborious reading, especially since I carefully read the "editor's" footnotes. However, I found the effort quite worthwhile as I became acquainted with principle characters, all of whom are authentic historical personages. Besides Stoker, there are Lady Jane Wilde (oscar Wilde's mother), Thomas Henry Hall Caine (a writer who was a far more successful and popular novelist than Stoker during the late 19th century but now totally and with good reason forgotten), Henry Irving, Ellen Terry, and Constance Wilde.In the second section, we also meet most notably Dr. Francis Tumblety who remains one of the primary persons suspected of the infamous and heinous slayings. The latter half of the book includes Inspector Frederick Abberline who, as Jack The Ripper devotees realize, has been portrayed on the screen by the likes of Michael Caine and Johnny Depp. Also prominent in the book is the secret society, The Hermetic Order Of The Golden Dawn, an authentic group which is still in existence.The story itself is quite engrossing as it progresses through three stages: the introductory background, the growing menace, and the very chilling and explicit supernatural horror of the latter half. The narrative develops from its very gentile yet colorful portrait of 19th century English society into graphic and gross descriptions of the crimes and isn't recommended for timid readers with sensitive digestion.Again, this is very rewarding reading for those who love 19th century gothic literature, but will likely bore those who haven't progressed beyond contemporary horror literature such as Stephen King, Dean Koontz, and recent graphic novels.
