"We banged in all the known past history of the victims, place names, locations, all the incidental details. Then we compared it to other people with the same names in London. The four names came out as the likeliest possible targets by virtue of the factors we included in the analysis. They were all prostitutes, the districts they lived in and where they were killed were similar, and there were some odd curves thrown out. Like, the original Annie Chapman’s body was found in Hanbury Street, while Fran’s friend of the same name was found slain in her flat in Hanbury Court, part of a building of another name. That was weird."
