About this episode

This episode discusses the cases of Helen Barthelemy and Mary Fleming, two victims of the infamous Jack the Stripper serial killings in London during the 1960s.

This is Part C of D of Undressing Jack the Stripper, an eight part series made in conjunction with the True Crime Enthusiast podcast. From the late 1950s to the mid-1960s, the bodies of eight sex-workers (Elizabeth Figg, Gwynneth Rees, Hannah Tailford, Irene Lockwood, Helen Barthelemy, Mary Fleming, Margaret McGowan and Bridget O’Hara) were found dumped in or near the River Thames in West London. Panic spread that a sadistic serial killer was on the loose who targeted young petite brunettes; stripped and strangled them, dumped each body within weeks and streets of each other. Yet with not a single witness to his crimes, even though several suspects have since been named, with no convictions, it’s a series of killing which remains a mystery to this day. After the success of their ten-part series, Psychopath: Two Side of Patrick MacKay, Mike at Murder Mile and Paul at the True Crime Enthusiast join forces once again to bring you an eight-part crossover series about one of Britain’s most infamous unsolved serial killing – Jack the Stripper. This episode is about Helen Barthelemy & Mary Fleming. Location: rear of 199 Boston Manor Road, Brentford, London, TW8 Date:  Friday…
