Very well-written, with loads of research and notes. Tells EVERYthing about each murder, plus lots of background info., even to the careers of each police officer who had anything to do with the case; even background information on all but one of the victims! Only 2 of the 5 were actually full-time, regular prostitutes and/or alcoholics; Doesn't really deal with the letters from "Jack." He refers to the murderer as "the murderer" or "the Whitechapel murderer."
