Blackmailer, police informer and prostitute, “Russian Dora,” 60, was found stabbed to death in her flat in Long Acre, Covent Garden, London, on Sunday, September 5th, 1948. Her real name was Dora Freedman and according to police her death, and that of another prostitute, was the work of an unknown sadistic killer. Even so, other sources have named Tony Machin, a one-time Soho “enforcer,” as the killer, and have even added a third prostitute to his murder tally, on a strictly professional basis.
