Jack the Ripper killed prostitutes, or so it has always been believed, but there is no hard evidence to suggest that three of his five victims were prostitutes at all. As soon as the bodies were discovered in dark yards or streets, the police assumed that they were prostitutes and that they had been killed by a maniac who had lured them to these places for sex. There is and never was any proof of this either. On the contrary, it was ascertained in the course of the coroners’ inquests that Jack the Ripper never had sex with his victims.
